LETTER FROM THE PRESIDENT
Dear Members and Guests,
Welcome to the 69th annual meeting of the
Southwestern Surgical Congress!
Clay Cothren Burlew, MD
The Program Committee, under the leadership of Dr.
Fred Pieracci, has planned an outstanding educational
program. There will be 33 podium presentations and
68 quick shot presentations, and 63 ePosters (up from
54 last year!). A new event, the Presidents’ Poster
Session with oral presentations, hosted by 12 of the Past
Presidents, will take place Sunday afternoon following
the Presidential Address.
The Postgraduate Courses in Trauma and in Emergency General Surgery will be
held on Sunday morning with nationally recognized experts. Additional highlights
of the meeting include the Past President’s Panel, the American College of Surgeons’
panel discussions, the Global Opportunities luncheon, mock oral boards for the chief
residents, and the invited lectures from Dr. Christine Cocanour, Dr. Rob Todd, and
Dr. John Moore.
No meeting of the SWSC would be complete without family-oriented activities to
complement the educational program. There will be kayaking/snorkeling, hula lessons,
the golf tournament, and yoga on the beach. The casual SWSC Reception will be
Tuesday evening on the Haloni Kai Lawn.
I hope you enjoy your time in Maui. Thank you for your loyalty and support of the
SWSC. I look forward to seeing each of you during the meeting.

1. OUTPATIENT LAPAROSCOPIC APPENDECTOMY CAN BE
SUCCESSFULLY PERFORMED FOR UNCOMPLICATED APPENDICITIS:
A SOUTHWESTERN SURGICAL CONGRESS MULTICENTER TRIAL

Background: Laparoscopic procedures offer the advantages of less pain, shorter
hospitalization, and quicker return to full activities. Because of these advantages,
many surgical procedures that formerly required hospitalization are now performed
on an outpatient basis, including cholecystectomy, hernia repair, fundoplication, and
bariatric procedures. An exception to this trend has been laparoscopic appendectomy,
which continues to have a 1-2 day average length of hospitalization. We hypothesize
laparoscopic appendectomy can be safely performed as an outpatient procedure.
Method: Seven institutions adopted a previously described outpatient laparoscopic
appendectomy protocol. Patients with uncomplicated appendicitis were candidates for
the protocol. Exclusion criteria included age < 18 years, pregnancy, and gangrenous/
perforated appendicitis. Per protocol, patients were dismissed from the recovery room
unless there was a clinical indication for admission. Patient demographics, success with
outpatient management, time of dismissal, morbidity, and readmissions were analyzed.
Results: During the 1-year study period, 376 patients with a mean age of 35.4 years
were included in the protocol including two hundred six men and one hundred seventy
women. Seventy-eight patients (21%) had pre-existing comorbidities including cardiac
disease (4%), hypertension (13%), diabetes (3%), renal disease (1%), morbid obesity
(1%), gastrointestinal (1%), and pulmonary (1%). Of the 376 patients, 299 (80%)
successfully completed the protocol and were managed as outpatients. There were
no conversions from laparoscopic to open appendectomy. Postoperative morbidity
occurred in twelve patients (3%) and included cardiac, pulmonary, surgical site
infections, reoperation, and urinary retention. The time of patient dismissals was
evenly distributed: 6 a.m.-noon: 22.3%, noon-6 p.m.: 29%, 6 p.m.-midnight: 23.5%,
midnight-6 a.m.: 25.3%. Twelve patients (3%) required readmission. Outpatient
follow-up occurred in 63% of patients.
Conclusion: An outpatient laparoscopic appendectomy protocol was successfully
applied at multiple institutions with low morbidity and low readmission rates.
Application of this practice nationally could reduce length of stay and decrease overall
health care costs for acute appendicitis.

OUTCOMES OF PATIENTS UNDERGOING URGENT LAPAROSCOPIC
APPENDECTOMY ON ANTITHROMBOTIC THERAPY

Background: The literature regarding outcomes in patients on irreversible
antithrombotic therapy (IAT) undergoing urgent laparoscopic appendectomy is
limited. The aim of this multicenter retrospective study was to examine the impact of
prehospital IAT on outcomes in this population.
Method: From 2010 to 2014, seven institutions from the SWSC MCT group
conducted a retrospective study to evaluate the clinical course of all patients who
underwent urgent/emergent laparoscopic appendectomy. Given statistically significant
demographic variations between IAT vs. No-IAT, two groups (IAT vs No-IAT) were
matched 1:1 based on age and gender. The IAT group was subdivided into IAT-Aspirin
only and IAT-Aspirin-Plavix. The IAT-Aspirin-Plavix subgroup was matched 1:1 to
controls based on age, gender, and comorbidity profile. The primary outcomes were
estimated blood loss (EBL) and transfusion requirement. Secondary outcomes included
infections (SSI - Surgical Site Infection, DSI - Deep Space Infection, and OSI - Organ
Space Infection), hospital length of stay (HLOS), complications, 30-day readmissions,
and mortality. A chi-square or Fisher’s exact test were employed for statistical
significance in large or small sample sizes, respectively. A p ≤ 0.05 is considered
statistically significant.
Results: Out of the 2,903 patients included in the study, 287 IAT patients were
identified and matched in a 1:1 ratio to 287 No-IAT controls. In the IAT vs Control
group, no significant differences in EBL (p=1.0), transfusion requirement during the
preoperative (p=0.5), intraoperative (p=0.3) or postoperative periods (p=0.5), infectious
complications (SSI p=1.0, DSI p=1.0, and OSI p=0.1), overall complications (p=
0.3), HLOS (p=0.7), 30-day readmission (p=0.3), or mortality (p=0.1) were noted.
Outcomes in the IAT-Aspirin only subgroup vs controls also failed to demonstrate
statistical significance. Additionally, in the IAT-Aspirin-Plavix subgroup vs controls, no
statistically significant differences in the assessed outcomes were observed.
Conclusion: Our results demonstrate no difference in outcomes between the overall
IAT group and Controls. Furthermore, analysis of the IAT-Aspirin only and IATAspirin-Plavix subgroups failed to show a significant difference in any outcome. Our
analysis suggests that urgent/emergent laparoscopic appendectomy is a safe procedure
in patients on IAT therapy. Prehospital use of IAT therapy as an independent factor
should not be used to delay laparoscopic appendectomy.

*3. FOLLOW-UP TRENDS AFTER EMERGENCY DEPARTMENT
DISCHARGE FOR THE ACUTELY SYMPTOMATIC HERNIA
Lara Spence MD, Eric Pillado BS, Dennis Kim MD, David Plurad MD
Torrance, CA
Background: It is felt that patients with acutely symptomatic hernias that present
to the Emergency Department (ED) can be discharged with clinic follow-up in the
absence of immediate indications for repair. However, little is known about the
outcomes after discharge. The purpose of this study was to evaluate the outcomes of
patients with symptomatic hernias discharged from the ED to include the percentage
that undergo surgery or re-present needing emergency repair.
Method: A retrospective analysis of patients discharged from the ED with a
symptomatic hernia over a three year period at a safety-net hospital was performed.
The patient’s laboratory values, radiological findings, the number of re-presentations to
the emergency department, time to being seen in the clinic for the purposes of elective
repair, time to surgical repair, operative outcomes, the length of stay, and complications
of surgery were analyzed.
Results: There were 111 patients who presented with an acutely symptomatic hernia
and were discharged with elective follow up. Age ranged from 19-99 years, with a
mean age of 49 years. Seventy-five (57.9%) were male, 23 (21%) had a prior repair,
and 30 (27%) had a chronically incarcerated hernia. The number of inguinal (45%)
and umbilical (43%) hernias were nearly equal. Less than a quarter (24%) of patients
were seen in follow up clinic after initial ED discharge. Mean days to this clinic visit
was 128 days and patients who were repaired electively waited a mean of 32 days to
surgery thereafter. Only 20 (18%) patients overall eventually underwent hernia repair
where 43% were emergent. Twenty-five percent of patients bounced back once, 6%
bounced back twice and 5% bounced back three times. In patients returning to the
ED at least once, 32% required emergency repair where 2 (7%) underwent laparotomy.
Of these patients, most (78%) were never seen in their scheduled clinic visit to arrange
elective repair. The most common reasons for not undergoing more immediate repair
was obesity. Other common reasons were cirrhosis, uncontrolled diabetes, and patient
request.
Conclusion: In this population, only one quarter of the patients evaluated by a
surgeon after initial ED visit for a symptomatic hernia followed up in the clinic and
even fewer underwent hernia repair. Half of those that underwent surgery occurred
emergently after re-presenting to the ED. Failure of follow up after an ED visit for an
acutely symptomatic hernia leaves many patients at risk for needing emergency surgery.
Barriers to follow-up must be studied in this population of patients.

*4. DAY VERSUS NIGHT LAPAROSCOPIC CHOLECYSTECTOMY:
A COMPARISON OF OUTCOMES AND COST
SS Siada DO, SM Schaetzel MD, AK Chen MD, HD Hoang MD, FG Wilder MD,
RC Dirks PhD, JW Davis MD
Fresno, CA
Background: Acute cholecystitis is a common cause of the acute abdomen making
laparoscopic cholecystectomy (LC) one of the most common procedures performed
in the United States. Early treatment of acute cholecystitis has been advocated to
reduce morbidity, length of stay, and risk of complications. However, recent studies
have suggested higher complication and conversion to open rates for nighttime LC
and recommend against the practice. We hypothesize that patients undergoing
cholecystectomy at night have decreased length of stay and cost with no difference in
complication and conversion rates compared with daytime cholecystectomy.
Method: A retrospective review, in a 650-bed tertiary-care hospital, of all patients
with acute cholecystitis who underwent LC from August 2011 through June 2015
was performed. Patients who underwent elective cholecystectomy, incidental
cholecystectomy, a planned open cholecystectomy, had gallstone pancreatitis or
choledocholithiasis, and those admitted to the medicine service were excluded. Day
was defined as LC that started after 7 am and before 5 pm, and night LC started
after 5 pm and before 7 am. Variables that were analyzed included patient age,
gender, body mass index (BMI), American Society of Anesthesiologists (ASA) class,
presence of pre-operative systemic inflammatory response syndrome (SIRS), length
of operation, length of stay (LOS), cost of hospitalization, and complications. These
variables were compared between patients undergoing day cholecystectomy and night
cholecystectomy.
Results: During the study period, 1552 patients with a diagnosis of acute cholecystitis
who underwent laparoscopic cholecystectomy were analyzed; 867 made up the study
population and 685 met exclusion criteria. Of the patients in the study cohort, 647
(75%) had LC during the day and the remainder had LC at night. There was no
statistical difference in age, BMI, gender distribution, and presence of SIRS between
patients undergoing day and night operations. Patients undergoing night LC were
more likely to be ASA class 3 or 4 than the day LC group (37% vs 30%, p = 0.05).
Conversion to open rate was higher in the day LC group (9% vs 5%, p = 0.02).
Length of stay was shorter in the night group (2.4 vs 2.8 days, p = 0.002) and cost of
the hospitalization was lower in the night group ($4244 vs $4513, p = 0.22). Patients
without SIRS who underwent night LC had a greater reduction in length of stay (2.1 vs
2.7 days, p = 0.001) and cost of hospitalization ($3911 vs $4342, p = 0.14). There was
no statistical difference in the use of cholangiography, length of operation, mortality,
and rate of complications between the day and night groups.
Conclusion: Performing LC at night has no increased risk of complications, speeds
patient care, and decreases length of stay.

*5. ADDRESSING THE QUALITY AND COSTS OF CHOLECYSTECTOMY
AT A SAFETY NET HOSPITAL
RP Won MD, S Friedlander MPH, SL Lee MD
Torrance, CA
Background: Safety-net hospitals have limited resources, yet care for a
disproportionate share of low-income, uninsured, and otherwise vulnerable patients.
Complex, elective surgery at safety-net hospitals has been associated with inferior
outcomes and increased costs. However, it is unclear how safety-net burden affects
common urgent surgical procedures. The objective of this study was to evaluate the
effects of safety-net burden on the outcomes of cholecystectomy.
Method: The California State Inpatient Database was queried for all cholecystectomies
performed from 2005-2011. The hospitals performing cholecystectomy were then
stratified by safety-net burden: low-burden hospitals had the lowest quartile of
uninsured/Medicaid patients (0-14%), medium-burden hospitals had the middle
two quartiles (15-41%), and high-burden hospitals had the highest quartile (>42%).
Hierarchical and multivariate analysis were then performed with primary outcomes
including rates of advanced disease (perforation or hydrops), laparoscopy, morbidity,
length of hospitalization, and cost.
Results: High-burden hospitals treated a higher proportion of minorities (p<0.01) and
were the least likely to use laparoscopy (p<0.01). Rates of advanced disease, specifically
perforation and hydrops, were similar across all groups, yet high-burden hospitals had
the lowest morbidity (p<0.01). Low-burden hospitals had the longest mean length of
hospitalization (p<0.01), while high-burden hospitals had the lowest costs (p<0.01).
Multivariate analysis failed to show any differences in rates of laparoscopy or advanced
disease. However, multivariate analysis confirmed high-burden hospitals had the lowest
rates of complications (RR -0.33, 95% CI -0.46, -0.19, p<0.01) and the lowest costs
(cost difference -5592, 95% CI -8928, -2256, p<0.01). Length of hospitalization also
trended down with increasing safety-net burden (p=0.06).
Conclusion: Cholecystectomies at safety-net hospitals were associated with lower
morbidity and cost, challenging the stigma that safety-net hospitals have inferior
outcomes. Additional research is needed to evaluate how safety-net hospitals achieved
these results, as it may help improve all surgical outcomes at under-resourced hospitals.

6. ACUTE POST-OPERATIVE DELIRIUM INCREASES LONG TERM
MORTALITY IN OLDER SURGICAL PATIENTS
Moskowitz EE, Overbey D, Jones T, Jones E, Arcomano T, Moore JT, Robinson TN
Denver, CO
Background: Post-operative delirium is associated with increased morbidity and
mortality up to 1 year in older surgical patients. There is limited data on long term
outcomes for elderly patients who have delirium. The purpose of this study was to
determine if the presence of postoperative delirium can predict long term mortality
in older surgical patients. We hypothesize that post operative delirium attributes to
increased mortality over a 5 year period.
Method: Patients aged 50 years and older undergoing elective surgery with a planned
ICU admission were prospectively enrolled between 2007-2011. Preoperative
demographics, Charlson comorbidity index, cognitive function, psychiatric history, and
alcoholism screening were recorded. Factors associated with delirium including age,
operation type, labs, and medications were also included in the analyses. Post-operative
delirium was defined using ICU Confusion Assessment Method (CAM-ICU) Scores.
Long term outcomes were obtained via retrospective chart review.
Results: One hundred and seventy two patients were enrolled during the five year
study period. Mean patient age was 64±8years and the majority were male (96.5%).
Seventy five patients experienced delirium during their hospitalization (43.6%). Five
year follow-up data was available for 164 patients (95%). Mortality was 58.6% (41/70)
in patients with delirium compared to 12.8% (12/94) in patients without delirium
(p<0.001). Age, ICU length of stay, Charlson Index, operation type, and delirium were
significant on both univariate and multivariable analyses (p<0.05). Five year mortality
was 7.35 fold greater for patients who had delirium on multivariate analysis. (See Table
1 for comparison).
Conclusion: Post-operative delirium independently predicts a seven fold increase
in 5 year mortality. Delirium in the immediate postoperative period has lasting
consequences. The identification and prevention of postoperative delirium in elderly
patients is critical to long term survival.

*7. TARGETING RESUSCITATION TO NORMALIZATION OF
COAGULATING STATUS: HYPER AND HYPOCOAGUALABILITY
AFTER SEVERE INJURY ARE BOTH ASSOCIATED WITH INCREASED
MORTALITY
HB Moore MD, EE Moore MD, BR Huebner MD, IN Liras MD, CC Burlew MD,
FM Pieracci MD, CE Wade PhD, Sauaia A MD PhD, BA Cotton MD
Denver, CO
Background: Correcting hypocoagulability has been the primary focus of resuscitation
in trauma patients, but the impact of hypercoagulability early after injury is poorly
defined. Fibrinolysis shutdown (impaired fibrinolysis) has recently been reported to be
the dominant phenotype of altered coagulation following injury. However, fibrinolysis
resistance has not been evaluated in the context of additional coagulation factors
attributed to hypercoagulability. We hypothesize that the predominant phenotype
of postinjury coagulopathy is hypercoagulability, largely attributable to impaired
fibrinolysis.
Method: Blood samples from 160 healthy volunteers assayed with rapid
thrombelastography (R-TEG) were used to identify thresholds of hypo and
hypercoagulability (above or below the interquartile range) of Activated clotting time
(ACT), angle, maximum amplitude (MA), and lysis at 30 minutes (LY30). These
cutoffs were then evaluated in 2,504 severely injured trauma patients from two level 1
trauma centers with blood samples obtained within an hour of injury. The four R-TEG
indices were classified as hypocoagulable (hypo), normal, or hypercoagulable (hyper) in
all of these patients. Differences in the prevalence of hyper and hypo were contrasted
to the distribution of healthy volunteers using the Goodness of Fit test. In-hospital
mortality, cause of mortality, and massive transfusion (>10 untits of RBC in 6 hours)
were also assessed between composite coagulation status of patients using a Chi Square
analysis.
Results: The median injury severity score (ISS) of the trauma population was 25
with a mortality rate of 22%. All TEG variables evaluated had a different prevalence
compared to the healthy volunteer population (p<0.001 for all table 1). Only 9% of
all trauma patients had all 4 TEG indices within the interquartile range of health
volunteers (normal), while 41% of patients were hyper, 22% hypo, and 28% had a mix
of hyper and hyper. In the hyper group: 47% had a short ACT, 55% had a steep angle,
57% had an elevated MA, and 45% had a low LY30. In the mixed group a low LY30
was prevalent in the majority of patients (65%). The ISS between these cohorts was
different with hypo patients having a higher ISS (27 IQR 22-35) than mixed (25 IQR
21-30 p=0.004) and hyper (25 IQR 19-29 p<0.001). The mortality between the groups
was significantly different (normal 12%, hyper 19%, mixed 26%, and hypo 30%
p<0.001) and after logistic regression controlling for ISS, hypo (p<0.001) and mixed
coagulopathy (P<0.001) remained significant predictors of mortality with a trend
towards increased mortality with hypercoagulability (p=0.09). Massive transfusion was
significantly different between cohorts (p<0.001) with hypocoagulable patients having a
84

(cont.)
3-fold increased rate of MT compared to hypercoagulable patients (12% vs 4%). Cause
of mortality differed by coagulation status (p<0.001) with 44% (39/88) of hemorrhagic
deaths associated with the hypo group, and 55% (17/31) of all multiple-organ deaths
associated with the hyper group.
Conclusion: The majority of severely injured trauma patients present to the hospital
with deranged coagulation detected with R-TEG; the most common pattern being
hypercoagulability. These data support the ongoing need for goal directed resuscitation
in trauma patients, as empiric ratios of blood products only treat the hypocoagulability
aspect of TIC, while neglecting a potentially lethal hypercoagulable component.

8. IMPACT OF GERIATRIC CONSULTATIONS ON CLINICAL OUTCOMES
OF ELDERLY TRAUMA PATIENTS: A RETROSPECTIVE ANALYSIS
JP Dugan BS, KM Burns BS, M Baldawi MD, DG Heidt MD
Toledo, OH
Background: The elderly population accounts for the majority of cases of morbidity
and mortality secondary to traumatic injury, despite lower-energy mechanisms of injury
and fewer trauma admissions. Comprehensive geriatric wards demonstrate improved
clinical outcomes in the elderly hospital patient yet the benefit of inpatient geriatric
consultation teams remains unclear, particularly in the setting of trauma. Our center
established a mandatory geriatric trauma consultation service (GTCS) in January of
2015. We hypothesized that geriatric patients admitted during the period of mandatory
GTCS consultations would have better outcomes across all measures analyzed.
Method: We performed a single institution retrospective, non-randomized, pre- and
post-intervention analysis of a GTCS after obtaining IRB approval. All patients
admitted to the trauma service over 60 from January of 2014 to February 2016 were
eligible. Data was abstracted from the institution’s Trauma Service Database and the
EMR in order to measure the following outcome variables: mortality, length of stay,
complications, ICU admission, disposition status, and readmission within 30 days of
hospital release.
Results: Among the 1,102 patients over the age of 60 admitted to the trauma service
during the study period, 526 (48%) were in the pre-intervention cohort and 576 (52%)
were in the post-intervention cohort. There were no significant differences observed in
in-hospital mortality (2.9%, n=15 pre- vs. 3.1%, n=18 post-intervention, P=0.79), 30day mortality (3.6%, n=19 pre- vs. 3.6% n=21 post-intervention, P=0.976), mean ICU
length of stay (4.6 days, n=98 pre- vs. 5.1 days, n=101 post-intervention, P=0.55), mean
total length of stay (4.9 days, n=526 pre- vs. 4.8 days, n=576 post-intervention, P=0.78),
or complication rates (8.4%, n=44 pre- vs. 11.8%, n=68 post-intervention, P=0.059).
Despite no difference in complication rates, if a single complication was experienced,
patients seen after the implementation of the mandatory GTCS were nearly 3 times
more likely to experience multiple complications (1%, n=5, pre- vs. 2.6%, n=15, postintervention, P=0.04, OR=2.78). Patients in the GTCS group were more likely to be
discharged home (40.7%, n=214 pre- vs. 47.4%, n=273 post-intervention, P=0.025,
OR=1.3), but were four times more likely to be readmitted than the pre-GTCS group
(1.3%, n=7, pre- vs. 5.2%, n=30 post-intervention, P=0.000, OR=4.07).
Conclusion: We found the mandatory geriatric trauma consultation service to be no
more beneficial to patient outcomes than management exclusively by the trauma team,
and we in fact observed an increase in readmission rates. Multiple complication rates
were also higher following implementation of the GTCS. In summary, the additional
costs of and increased administrative and documentation burdens imposed by
mandatory geriatric consultations did not result in improved patient outcomes.

9. IS HEAD CT INDICATED AFTER EVERY GROUND LEVEL FALL IN THE
ELDERLY?
R Sartin BS, C Kim BS, S Dissanaike MD
Lubbock, TX
Background: The incidence of ground level falls in the elderly is increasing, along with
the ageing population in the US. Appropriate evaluation of these patients is a matter
of debate, with differing opinions on whether the routine use of advanced imaging
such as CT is indicated. We evaluated the clinical utility of routine head computed
tomography (CT) in this population.
Method: Retrospective review of all patients > 55years who presented to a level 1
trauma center after sustaining a ground level fall between January 2013 and May 2015.
Standard evaluation during this time at this institution included a chest radiograph and
a head CT scan. Inclusion criteria were GCS 15, hemodynamic stability and having
received a head CT scan.
Results: 148 positive findings were reported on head CT scans of 437 patients (34%).
94 resulted in a change in clinical management (64% of findings, 21.5% of entire
cohort). 19 patients required surgery, 59 had a medication change, 56 required ICU
admission and 84 had additional imaging. Risk factors for positive findings were age
> 85 years (p<0.03) and presence of a neurologic deficit on admission (p< 0.0001).
Patient sex, loss of consciousness at the time of event and history of anticoagulant or
antiplatelet medication use did not increase risk of intracranial injury in this cohort.
Conclusion: Head CT scan has a high rate of positive findings in elderly patients after
a ground level fall, even with a GCS of 15; the incidence of positive findings increased
with advancing age. We recommend routine head CT in the elderly presenting after a
ground level fall.

+10. PRETRANSFER CT SCANS ARE FREQUENTLY PERFORMED, BUT
RARELY HELPFUL IN RURAL TRAUMA SYSTEMS
DA Thornburg MS4, WE Paulson MD, PM Bjordahl MD
Sioux Falls, SD
Background: In rural trauma systems, many injured patients are assessed and
stabilized at community hospitals prior to transfer to a regional trauma center.
Subsequent evaluation often includes additional or repeated radiographic exams. Prior
studies have demonstrated that computed tomography (CT) scans are often repeated
at the receiving facility primarily due to difficulty in image transfer. The purpose of
this study is to evaluate the frequency and potential reasons behind repeat CT imaging
following transfer to a rural regional trauma center.
Method: Two hundred consecutive adult trauma patients transferred to a rural Level 2
trauma center from September 2014 through June 2015 were retrospectively evaluated.
Data considered included CT scans performed at transferring facilities, documentation
of the indication for transfer and intervention at the outside facility, level of trauma
activation, injury severity score, and repeat CT scans upon arrival to receiving facilities.
Repeat imaging was defined as CT scan performed upon arrival at the receiving trauma
center for a patient who underwent CT just prior to transfer. The majority of images
performed prior to transfer were viewed at the trauma center via the picture archiving
and communication system (PACS). The reason for repeating studies was recorded as:
(1) incomplete imaging, (2) change in patient condition, (3) inappropriate/inadequate
technique, (4) images not available, and (5) unknown/not determined.
Results: Three patients were excluded. 197 transferred patients’ records were evaluated.
152 patients (77.2%) underwent CT scan prior to transfer. CT scan findings were the
indication for transfer in 88 imaged patients (44.7%). One intervention (0.5%) was
performed as a result of CT imaging prior to transport, and resulted in unnecessary
iatrogenic injury. 84 patients (55.3%) received repeat CT imaging on at the trauma
center. There were no differences in rates of CT imaging based on injury severity,
mechanism, or age. The most common reasons for repeat CT scans were incomplete
initial imaging and inappropriate technique.
Conclusion: Repeat CT imaging in transferred trauma patients is very common.
Despite the lack of recommendations to perform CT imaging during initial
resuscitation, many trauma patients receive radiographic studies both prior to and after
the decision to transfer has been made in the rural community hospitals. Our results
suggest that management, aside from transfer decision, is very rarely altered as a result
of pre-transfer CT scans. In contrast to prior studies, the transmission of imaging data
was of minimal contribution to the rate of repeat CT imaging of transferred patients
in this series. The rural trauma system may benefit from improved protocols and
communication between providers in the community hospitals and trauma center to
provide prompt, efficient and safe care for rural trauma patients that omits evaluations
that do not impact care or outcome of this population.

*11. RETURNING FROM THE ACIDOTIC ABYSS: MORTALITY IN TRAUMA
PATIENTS WITH A PH <7.0
SW Ross MD MPH, BW Thomas MD, AB Christmas MD, KW Cunningham MD
MPH, RF Sing DO
Charlotte, NC
Background: Severe acidosis is part of the lethal triad and is a marker for mortality
in trauma. Venous blood gas (VBG) is a readily available, rapid lab in the emergency
department (ED). Subsequently, VBG is frequently used as an adjunct in the initial
trauma evaluation. We hypothesized that a VBG pH of <7.0 on ED presentation would
correlate with almost universal mortality in trauma patients.
Method: A retrospective analysis was performed on an institutional Level I trauma
center registry from 2013 to 2014. Pediatric and adult patients with initial pH ≤7.30
were included in the study. Patients without pH data were excluded. Patients were
then divided into two cohorts, <7.0 or≥7.0, and compared with standard bivariate
statistics. Hospital mortality was the primary outcome measured. Multivariate analysis
controlling for mechanism of injury (MOI), gender, age, injury severity score (ISS), and
initial Glasgow Comas Scale (GCS) was performed by pH status for charges, length of
stay (LOS), ventilator days, and mortality; p<0.05 set as statistical significance.
Results: There were 593 patients included in the analysis: 66 <7.0, 527≥7.0. The
majority of MOI were blunt (78.6%) with fewer penetrating (21.4%). Patients in the
<7.0 cohort were younger and had lower initial GCS and base deficit; p<0.05. However,
they had similar distribution of male sex, Caucasian race, mean ISS (22.7±14.9 vs.
19.2±13.8), and rate of penetrating trauma (16.7 vs. 20.9%); p>0.05. The lower pH
cohort was more likely to proceed directly to surgery (31.8 vs. 18.4%) or incur an ED
death (16.7 vs. 1.5%), but less likely to be discharged home (18.2 vs. 54.5%); p<0.01.
Mortality was 3x higher in the <7.0 pH cohort (62.1 vs. 20.3%; p<0.0001), however
there was no threshold for a pH below which there was 100% mortality. Despite higher
mortality, the <7.0 group had equivalent ICU LOS (7.2±9.6 vs. 6.0±6.2 days), ventilator
days (6.2±10.9 vs. 6.1±8.2 days), hospital LOS (8.8±15.7 vs. 9.0±11.0 days), and hospital
charges ($157,943vs. $129,393) as the≥7.0 cohort; p>0.05. On multivariate analysis, pH
<7.0 was not associated with increased ICU or hospital LOS, ventilator days, or charges;
p>0.05. However, even after controlling for these confounding variables, initial pH was
found to be an independent predictor of inpatient mortality at several cut-points (Odds
Ratio, 95% CI; p value): <6.7 (12.15, 1.14-129.7; p=0.039), <6.8 (4.83, 1.28-18.21;
p=0.020), <6.9 (5.66, 2.28-14.07; p=0.0002), <7.0 (6.33, 3.29-12.19; p<0.0001), <7.1
(3.76, 2.28-6.19; p<0.001). and <7.2 (2.38, 1.42-3.99; p=0.001)
Conclusion: Severe acidosis with pH <7.0 is associated with 62.1% mortality in trauma
patients, and higher rates of ED death, need for initial emergent surgery, and lower
rates of discharge home. However, there was no pH value where patient mortality
reached 100%. This data indicates that while patients with severe acidosis are at
increased risk for mortality, a pH <7.0 is not synonymous with futility.

Background: In its 2016 “Choosing Wisely” guidelines, the Society of Surgical
Oncology made the recommendation that women≥ 70 years of age with clinically
lymph node (LN) negative (-), hormone receptor (HR) positive (+) breast cancer should
not routinely be staged with a sentinel LN biopsy (SLNB). We sought to understand
the implications of such a recommendation in terms of adjuvant therapy decisionmaking.
Method: The National Cancer Database (NCDB), which captures data on over 70%
of cancer patients, was queried for patients who had clinically LN-, HR+ breast cancer.
Statistical analyses were performed to determine the impact of LN evaluation on
receipt of adjuvant chemotherapy and radiation therapy.
Results: Between 2004 and 2013, there were 193,728 patients in the NCDB who were
between the ages of 70 and 90 (median, 77) when they were diagnosed with clinically
LN-, HR+ invasive breast cancer. The median tumor size was 14 mm. 154,504 patients
(79.8%) had regional LN surgery; of these, the median number of LNs examined
was 3 (range; 0-88). 23,126 (15.1%) were found to be LN+; the median number of
positive LNs was 1 (range; 1-57). 63.6% of patients had a lumpectomy, 31.4% had a
mastectomy, and 4.9% had no surgery for their breast cancer primary. Of the 97,866
patients who had a lumpectomy with LN assessment, there was a significant difference
in receipt of radiation therapy between LN- and LN+ patients (73.8% vs. 81.4%,
respectively, p<0.001). Post-mastectomy radiation therapy also varied significantly
based on LN status (30.3% vs. 5.1% for LN+ vs. LN-, respectively, p<0.001). In
addition, patients with LN+ disease were more likely to receive chemotherapy (28.3%
vs. 5.5% for LN- patients, p<0.001), and more likely to receive hormonal therapy
(83.6% vs. 82.7%, p<0.001). On multivariate analysis, patients who were LN+
remained significantly more likely to receive chemotherapy independent of patient age,
race, insurance status, income, tumor size, grade, comorbidities, receipt of hormonal
therapy, or region of the country in which patients resided (OR = 5.587; 95% CI:
5.340-5.847, p<0.001). Similarly, on multivariate analysis of patients undergoing
a lumpectomy, LN+ patients were significantly more likely to receive radiation
therapy, independent of patient age, race, insurance status, income, tumor size, grade,
comorbidities, receipt of hormonal therapy, region of the country in which patients
resided, or crowfly distance to the nearest radiation facility (OR = 1.388; 95% CI:
1.309-1.472, p<0.001).

Conclusion: While only 15% of patients who are≥ 70 years of age with clinically
LN-, HR+ breast cancer will have positive nodes, and over 80% of them will receive
hormonal therapy as part of their treatment regimen, LN status seems to be an
important factor in decision-making regarding addition of chemotherapy and/or
radiation therapy in these patients. Hence, to avoid SLNB in these patients must be
considered in a multidisciplinary context.

*13. RADIOACTIVE SEED LOCALIZATION FOR BREAST CONSERVATION
SURGERY: LOW POSITIVE MARGIN RATE WITH NO LEARNING CURVETHE NEW GOLD STANDARD?
CS Velazco MD, MS, N Wasif MD, MPH, BA Pockaj MD, RJ Gray MD
Phoenix, AZ
Background: Radioactive seed localization (RSL) is an alternative to wire localization
for non-palpable breast lesions. Although most new procedures have a “learning curve”,
the skills required for RSL can be mastered easily by breast surgeons. We compared the
rate of positive margins (the key outcome of breast lesion localization) at our institution
during our early and later experience with RSL for evidence of a learning curve.
Method: A retrospective review of RSL procedures at a single institution was
performed. To adequately power the study to detect a 3% absolute reduction in positive
margin rates inclusion of at least 300 patients was calculated as an adequate sample
size. Three surgeons were included in this study. The first 100 cases and up to the last
100 RSL cases for each surgeon were examined. Intraoperative pathologic examination
with selective frozen section analysis was used in all cases. Positive margins were
defined as ink on tumor. Exclusion criteria included male sex, non-invasive carcinoma
and palpable tumors. Statistics were calculated using two-tailed Fisher’s exact test.
Results: Total experience with RSL for the three surgeons ranged from 142 to more
than 500 cases. The rate of positive margins among the first 100 of each surgeons’
experience with RSL (n=300) was 2.3% and the rate after exceeding 100 RSL
procedures or more (n=242) was 3.3% (p=0.62). Individual surgeon’s positive margin
rates ranged from 2-5% in the early experience and 2-7% in the later experience
(p=NS). When limiting the early experience to the first 50 cases only, the rate of
positive margins was 2% (n=150) for the early experience and 4% for the late experience
(n=150, p=0.49). Individual surgeon’s rates of positive margins for this division of
experience was 2% for all surgeons for the early experience and 2-6% for the late
experience. Setting the threshold at the first 10 or the first 20 cases also did not reveal
an increase in positive margin rates (0% and 0%, respectively).
Conclusion: Radioactive seed localization for breast conservation surgery has a low rate
of positive margins even early in a surgeon’s experience. Implementation of RSL can be
done with no evidence of a learning curve to achieve a low rate of positive margins.

DW Northfelt MD, KS Anderson MD PhD, AE McCullough MD, IT Ocal MD, BA
Pockaj MD
Phoenix, AZ
Background: In 2013, the results of ACOSOG Z1071 demonstrated the efficacy of
neoadjuvant therapy in axillary disease. We reviewed a cohort from a tertiary care
center to validate these results and examine our experience.
Method: From 2002 to 2015 we performed a retrospective review of a prospectively
collected database of women with breast cancer who underwent neoadjuvant therapy.
Patient factors, tumor factors, and specifically axillary staging procedures and response
were analyzed. Neoadjuvant therapy varied per medical oncology discretion. For
analysis, patients with stage IV disease, inflammatory breast cancer, and no axillary
staging procedure were excluded.
Results: Of 289 women, 38 (13%) had inflammatory breast cancer, 82 (28%) had
triple negative breast cancer (TNBC), 126 (44%) had ER+HER2- breast cancer and
77(27%) had HER2+ disease. The mean age of patients was 56 years (SD=12). The
majority of patients, pre-neoadjuvant therapy, were clinical stage IIA [72 (25%)],
IIB [62 (22%)] or IIIA [52 (18%)], respectively). After excluding patients with
inflammatory breast cancer, no axillary staging procedures, and stage IV disease, 225
patients were included for analysis. Pre-neoadjuvant therapy, clinical staging was cN0
in 54%, N1 in35%, N2 in 8%, and N3 in3%. Axillary US pre-neoadjuvant therapy
was performed in 62% of cases. 30% of these underwent biopsy, of which 80% were
positive. Forty-nine patients had planned axillary lymph node dissection (ALND,
22%), 126 had sentinel lymph node biopsy (SLNB) only (56%, and 50 SLNB +
completion axillary lymph node dissection (CALND, 22%). In patients undergoing
only SLNB, the mean number of lymph nodes resected was 4.2 (SD=3.3) compared to
15.1 (SD=7.0) for patients who underwent a CALND and 16.0 (SD=8.1) for SLNB +
CALND. Pathologically positive lymph nodes were found in 30 (63%) cases of patients
who underwent a CALND, 19 (17%) SLNB only and 44 (96%) in SLN + CALND.
Decisions not to proceed with CALND in those patients who had a positive SLNB
were made by the multi-disciplinary team caring for the patient. 31 (15%) who were
deemed to be N0 prior to neoadjuvant therapy were found to have axillary disease
at definitive surgery, whereas 32 (15%) who had clinical N1, 2, or 3 disease prior to
neoadjuvant therapy had no axillary metastases at definitive surgery. The use of SLNB
increased significantly over the study period. Prior to 2013, 33% (26/80) underwent
planned ALND and 67% (54/80) underwent SLNB or SLNB+ALND compared to
16% (23/145) and 84% (122/145), respectively, after 2013 (p=0.004).

There was no significant difference in overall survival or local/regional recurrence
between patients who underwent ALND, SLNB, or SLNB+ALND (p=0.41 and
p=0.95). A total of 3 axillary recurrences were found: CALND 1, SLNB 1, and 1
SLNB+ CALND.
Conclusion: Patients treated with neoadjuvant therapy can be safely selected to
undergo axillary staging using SLNB with infrequent axillary recurrences. Until results
of pending trials are available to further define the need for ALND, multidisciplinary
clinical judgment should guide the decision to pursue CALND with routine ALND in
at least the high risk patients (N2, N3, or TNBC).

*15. SURGICAL LYMPH NODE EVALUATION IS ASSOCIATED WITH
IMPROVED PROGNOSIS IN NODE NEGATIVE SWEAT GLAND CANCER
L Kilgore MD, G Winter BS, E Spornitz MA, D Subramaniam PhD, GJ Chen PhD,
JMV Mammen MD PhD
Kansas City, KS
Background: Sweat gland malignancies are rare cancers with an incidence of
approximately 5 cases per 1 million individuals annually. Surgical lymph node
evaluation is commonly used to better stage patients for many malignancies, commonly
by sentinel lymph node biopsy. While wide local excision of the primary tumor is
commonly performed, a standard of care for the surgical evaluation of lymph nodes for
sweat gland malignancies has not been defined. In this study, we sought to determine
if patient survival was improved in patients who had wide local excision with surgical
nodal evaluation versus wide local excision alone.
Method: We queried the National Cancer Database for all cases of sweat gland
malignancies from 1999 to 2013. For the further analysis, we included patients who
were clinical N0M0 with any T stage who had undergone surgical resection. In
addition to descriptive statistics, multivariate Cox-regression survival analysis was
performed with a p value < 0.05 denoting significance.
Results: A total of 2439 evaluable patients who had surgery were identified in the
National Cancer Database that were N0 and M0. 360 patients underwent wide local
excision and surgical nodal evaluation and were found to be pathologic N0 (Group 1).
2079 patients underwent wide local excision alone without surgical nodal evaluation
(Group 2). The median age of Group 1 patients was 58 years old versus 68 years
old in Group 2 patients. On multivariate analysis, younger age, female gender, low
grade, lower T stage, and surgical evaluation of lymph nodes were all associated with
improved survival with p values less than 0.05. 5 year survival for patients who had
surgery with lymph node evaluation alone was 58.2% versus 49.0% for patients who
had surgery without lymph node evaluation (p < 0.01).
Conclusion: Surgical evaluation of lymph nodes has been shown to be important in
order to appropriately stage patients with melanoma, breast cancer, and Merkel cell
cancer. In this study, we demonstrate that surgical evaluation of lymph nodes is an
independent prognostic factor towards better survival in sweat gland cancer patients
who are lymph node negative. Due to the challenge of performing a randomized study
in this rare disease, our data supports the routine use of sentinel lymph node biopsy in
patients with sweat gland malignancies.

*16. RE-EXCISION RATES AFTER BREAST CONSERVING SURGERY
FOLLOWING THE 2014 SSO-ASTRO GUIDELINES
AA Heelan Gladden MD, S Sams MD, C Finlayson MD, AL Gleisner MD, N
Kounalakis MD, RJ Brown MD, T Chong MD, DW Mathes MD, C Murphy MD
Aurora, CO
Background: Reported re-excision rates after breast conserving surgery (BCS) are
variable due to controversy over the definition of a “positive” margin. The Society of
Surgical Oncology (SSO) and the American Society for Radiation Oncology (ASTRO)
published consensus guidelines in 2014 where “no ink on tumor” was the new margin
requirement for invasive breast cancer after BCS. We sought to evaluate whether reexcision rates at our own institution were affected by the 2014 guidelines.
Method: All breast cancer patients treated by BCS between January 1, 2010, and
March 1, 2016 were identified. We utilized a guideline adoption date of June 1, 2014.
Re-excision rates were calculated and tumor characteristics recorded. Margin size was
defined as positive (tumor on ink) or close (≤ 2mm). Student’s t-test and Chi-squared
were performed where appropriate.
Results: During the designated time period, 759 patients underwent BCS, 434 before
the guideline adoption date and 325 after. Of the 434 patients who underwent BCS
prior to guideline adoption, 60 required re-excision. After guideline adoption, 39 of
the 325 patients required re-excision. Overall re-excision rates before and after the
guideline adoption date were 13.8% and 12% respectively (p = 0.46). Patient and
tumor characteristics were similar between time periods.
When stratified by reason for re-excision by tumor type, the distribution of patients
requiring re-excision before the guideline adoption date was 20% for invasive
carcinoma, 51.7% for DCIS, and 28.3% for both. After the guideline adoption date,
the distribution of patients requiring re-excision was 25.6% for invasive carcinoma,
53.8% for DCIS and 25% for both (p= 0.63).
When stratified by margin size on initial lumpectomy, the distribution of patients
who underwent re-excision for positive margins before guideline adoption was 66.7%
for invasive carcinoma, 26% for DCIS, and 82% for both. After guideline adoption,
the distribution of patients requiring re-excision for positive margins was 90% for
invasive carcinoma, 47% for DCIS, and 85.5% for both. The distribution of patients
requiring re-excision for close margins before guideline adoption was 33.3% for
invasive carcinoma, 74% for DCIS, and 17% for both. After guideline adoption, the
distribution of patients requiring re-excision for close margins was 10% for invasive
carcinoma, 52% for DCIS, and 12.5% for both (p= 0.10).
Conclusion: Overall re-excision rates at our institution did not significantly decrease
after release of 2014 SSO-ASTRO guidelines, even when stratified by tumor type
and size of margin. Re-excision rates were highest for DCIS and comprised over half
of all re-excisions. The 2014 SSO-ASTRO guidelines had minimal impact on our
institution’s re-excision rate as most re-excisions were done for margins containing
DCIS, which were not addressed by the new guidelines.

17. SOUTHWESTERN SURGICAL CONGRESS JACK BARNEY AWARD
COMPETITION PRESENTERS - WHERE ARE THEY NOW?
SN Kothari MD, KJ Kallies MS
La Crosse, WI
Background: Participation in scholarly activity is required for faculty and residents
by the Accreditation Council for Graduate Medical Education. Resident research
presentations at regional, national, and international surgical conferences offer a unique
opportunity and may encourage presenters to pursue future research endeavors after
graduation. The Jack A. Barney award was instituted in 1987 at the Southwestern
Surgical Congress (SWSC) to recognize the top-ranked resident paper.
Method: The programs from the 2010-2016 SWSC annual meetings were reviewed for
all presenters eligible for the Jack Barney award. In addition, all recipients of the Jack
Barney award from 1987-2016 were included. A literature search for all publications
authored by eligible presenters and recipients was completed. Fellowship, practice
location and type were reviewed. Descriptive statistics were applied.
Results: There were 109 presentations from 100 unique presenters eligible for the Jack
Barney award from 2010-2016, and 28 unique recipients of the award (2 presenters
won twice) from 1987-2016. Among the eligible presenters, 95% were residents, 4%
fellows, and 1% medical students. There were 9 presenters who had more than one
eligible presentation at separate annual meetings. Of the unique presenters eligible for
the award, 75% were from University residency programs, 23% were from independent
residency programs, and 2% from military programs. Forty-four presenters have
completed their surgical training; of whom, 28 (64%) completed fellowships. Thirty-six
(82%) presenters currently practice in a community/private practice hospital, 5 (11%)
in a university setting, 2 (5%) in a non-U.S. setting, and 1 (2%) in a military hospital.
Overall, subsequent scholarly articles were published in the peer-reviewed literature
by 41% of presenters. Among the 28 Barney award recipients, 24 (86%) and 4 (14%)
represented University and independent residency programs, respectively. Currently,
16 (57%) practice in community/private practice, and 9 (32%) practice in University
settings. Three recipients are still in training. Twenty recipients completed fellowships,
and 20 (71%) published after residency. Overall, 13 of the 100 (13%) eligible presenters
are current SWSC members, and 7 of 28 (25%) award recipients are current SWSC
members.
Conclusion: The Jack Barney award recognizes scholarly activity among surgery
trainees at the SWSC. Subsequent peer-reviewed publications were frequent among
eligible presenters and award recipients. Low retention rates of resident presenters as
SWSC members provide an opportunity for further recruitment and retention as they
have to potential to be future leaders of the SWSC.

Hunter MD, T Cook, Y Haque, K McLean, J Morgan, V Agrawal PhD, K Taubman
MD, MS Truitt MD
Dallas, TX
Background: The incidence of Posttraumatic Stress Disorder (PTSD) among
practicing physicians has been demonstrated to be higher than the general population.
Physician Burnout (PBO) is also on the rise. Given the potential overlap of symptoms,
we aim to evaluate the incidence of PTSD and PBO among surgery residents. To our
knowledge, no previous work has evaluated these two conditions in this cohort.
Method: A cross-sectional national survey of surgery residents was conducted.
Screening for PTSD and PBO was performed using the Primary Care PTSD Screen
(PC-PTSD) and a previously validated abbreviated burnout tool. Three or more
positive responses to the PC-PTSD screen were considered positive for PTSD (PTSD+).
Causative traumatic factors associated with PTSD were queried. Responses to PBO
questions were grouped into low, intermediate and high scores within the categories of
depersonalization and emotional burnout. Eleven risk factors for PTSD and PBO were
examined including resident demographics and residency characteristics. A chi-square
or Fisher’s exact test were employed for statistical significance in large or small sample
sizes, respectively.
Results: From September to October 2016, 549 surgery residents completed the survey.
A positive PTSD screen was noted in 22% of respondents (n=113), and 51% reported
symptoms of PTSD. Overall, there were significant differences in the incidence
of PTSD by Post-Graduate Year (PGY). PGY2 residents were at highest risk of
developing PTSD, followed by PGY4, PGY3, and PGY1 residents respectively. Upper
level residents (PGY5, PGY6, and PGY7) exhibited the lowest risk. Overwhelming
responsibilities at work (22%), discord between personal and professional life (19%),
and criticism or bullying by attendings (13%) were the most frequently cited stressful
experiences. No other risk factors were found to be significant.
Of respondents, 35% (n=191) were positive for a high degree of PBO (PBO+). The
emotional exhaustion and depersonalization subcomponents were positive in 23%
(n=125) and 29% (n=157) respectively. Degree of depersonalization increased with
PGY (p=0.003). Additionally, a greater proportion of women reported burnout on
the emotional exhaustion component (p=0.02). Finally, 37% of all PTSD+ surgery
residents were positive for one of the components of PBO as well (p < 0.001).
Conclusion: Our data indicate an incidence of 22% and 35% for PTSD and PBO,
respectively, among surgery residents. Additionally, we noted a strong association
between PTSD+ and PBO+ residents. Given the apparent relationship between PTSD
and PBO, screening and coping strategies should be considered. Physician satisfaction
has been linked to improved quality of care, cost containment, patient safety, and
overall patient satisfaction. As healthcare evolves, the wellness of physicians and
residents cannot be overlooked.

19. VENOUS THROMBOEMBOLISM IN COMMON LAPAROSCOPIC
ABDOMINAL SURGICAL OPERATIONS
R Fazl Alizadeh MD, S Sujatha-Bhaskar MD, MJ Stamos MD, NT Nguyen MD
Orange, CA
Background: Venous thromboembolism (VTE) is a substantial postoperative
complication with severe consequences following abdominal operations. The natural
history of this disease process appears to significantly vary between different surgical
procedures. In this review, we intend to examine the incidence and course of VTE
among different abdominal surgical operations and assess potential risk factors.
Method: The ACS-NSQIP databases were utilized to identify patients who underwent
laparoscopic abdominal operations from 2005 to 2014. All the malignant cases were
excluded. All the patients with VTE were identified and divided into six groups based
on sub-specialty: colorectal, bariatric, gall bladder, esophagus, hernia, and appendiceal
resections. Demographic patient data, preoperative risk factors, and postoperative
complications were reviewed for each of these six cohorts.
Results: 2424 out of 750060 (0.3%) patients diagnosed with VTE during this time
period. Of these, 734 out of 65512 (1.1%) were colorectal, 539 out of 153552 (0.4%)
were bariatric, 489 out of 239499 (0.2%) were gall bladder, 276 out of 168963 (0.2%)
were appendiceal, 215 out of 91122 (0.2%) were hernia repair, and 171out of 31412
(0.5%) were esophageal resections. Patients undergoing colorectal operations had
the highest VTE risk and median age of this patient subset was 59. A high incidence
of comorbidities was noted as 50.2% of this patient population had an ASA score
> 2. Median operative length during colorectal procedures (187 min) was longer in
comparison to other abdominal operations. Patients with VTE following colorectal
procedure additionally demonstrated highest rates of pulmonary embolism (33.9%),
organ space infection (15.9%), and sepsis (14.4%). Length of stay was prolonged in
colorectal operations including patients with VTE (13 days ±11.5) and without VTE (6
days ±8) in comparison to other abdominal operations.
Conclusion: Laparoscopic colorectal operations demonstrated the highest incidence of
VTE when compared against other abdominal operations. A high degree of suspicion
for potential VTE should be utilized during the postoperative phase.

20. PERIOPERATIVE COMPLICATIONS INCREASE THE RISK OF VENOUS
THROMBOEMBOLISM FOLLOWING BARIATRIC SURGERY
KL Simon MD, RM Higgins MD, TL Kindel MD PhD, MC Helm BS, JC Gould MD
Milwaukee, WI
Background: Morbidly obese patients are at an increased risk of venous
thromboembolism (VTE) following surgery. VTE, which includes deep vein
thrombosis (DVT) and pulmonary embolism (PE), has the potential to result in
significant morbidity and mortality. When a patient experiences a clinically significant
post-surgical complication, their risk of VTE may suddenly increase. Using a large
national database, we sought to determine the relationship between the most common
post-bariatric surgery complications (other than VTE) and a subsequent VTE in the
first 30 days following bariatric surgery.
Method: The American College of Surgeons-National Surgical Quality Improvement
Program (NSQIP) dataset between 2012-2014 was used to identify patients who
underwent primary or revisional bariatric surgery. The cohort included gastric
bypass (n=28,268), sleeve gastrectomy (n=30,258), bariatric revision (n=418), and
biliopancreatic diversion procedures (n=480). We examined 17 of the most common
perioperative complications including: wound dehiscence, surgical site infections,
reintubation within 48-hours of surgery, failure to wean from the ventilator,
pneumonia, sepsis, septic shock, blood transfusion, cardiac arrest, myocardial
infarction, ischemic stroke, reoperation, renal insufficiency, acute renal failure, and
urinary tract infection. Multivariate regression analysis was used to determine the effect
of post-operative complications on the risk of VTE.
Results: Of the 59,424 patients who met inclusion criteria, the overall incidence of
VTE was 0.5% (PE 0.2%; DVT 0.3%; n=282). The average time to diagnosis of DVT
was 14.3 days, while PE was 12.1 days. 80% of VTE events occurred after discharge,
but within the first 30 days after surgery. Patients with a post-operative VTE were more
likely to have previously had another major complication during their hospital stay
(21.3%; p<0.0001). Average post-operative length of stay in patients later diagnosed
with a VTE was 5.12 days, in comparison to 2.15 days for patients who did not have a
VTE (p<0.0001). Reoperation increased the risk of VTE 7.6-fold, renal complications
20-fold, cardiac complications 11.9-fold, pulmonary complications 21.7-fold, and SSI
6.2-fold (all p<0.0001). The more complications experienced by an individual patient,
the more likely they were to develop a VTE (Figure 1). Furthermore, 30-day mortality
increased 13.94 fold following VTE (p<0.0001).
Figure 1: Multivariate regression analysis assessing the impact of multiple postoperative complications on the risk of VTE within 30-days of surgery, after controlling
for age and sex.
Conclusion: Post-operative complications place patients at a significantly increased risk
of VTE following bariatric surgery. Once a significant complication has occurred, more
aggressive surveillance and preventative protocols should be put in place to address

this higher risk. Since the majority of VTE events occurred after hospital discharge,
studies to screen for lower extremity DVT, extended chemoprophylaxis after discharge,
and even considering insertion of inferior vena cava filters in those at highest risk,
are strategies that should be considered and may help minimize the incidence and
morbidity of these VTE events.

EXPENSIVE? THE USE OF HEM-O-LOK VERSUS ENDOSTAPLER DEVICES
MA Al-Temimi MD MPH, MA Berglin BA, AF Mousa BA, DJ Tessier MD, Samir
Johna MD MACM
Fontana, CA
Background: Few North American studies evaluated the use of Hem-O-Lok (HOL)
clip to secure the appendiceal stump and the mesoappendix during laparoscopic
appendectomy (LA). Our study evaluates the safety, efficacy and cost of using the HOL
clip in LA.
Method: We conducted a prospective cohort study of patients undergoing LA between
June and September 2016 at a single institution. Eight surgeons used the HOL clip
and twelve used the conventional endostapler during LA. Preoperative characteristics,
intraoperative details, and 30-day postoperative outcomes were compared using
univariate and multivariate analysis. Propensity score analysis was also used to adjust
for preoperative differences between the two groups.
Results: HOL clip was used in 45 out of 92 LA. The use of the HOL clip was
attempted in two patients, but the clip could not secure the thick stump. The stapler
was then used to complete these two procedures.
The minimum cost for the endostapler during LA was $273.13 ($101.97 for stapler
handle and $171.16 for stapler load) versus $32.14 for the HOL clip.
Age (mean+/-standard deviation (sd), 27.97 +/-16.01 vs. 32.1 +/-17.46), body mass
index (mean+/-sd, 25.93 +/-5.53 vs. 26.8 +/-6.98), gender (male, 40.4% vs. 40.0%),
any preoperative co-morbidity (51% vs. 63%) and resident participation (24.4% vs.
17.0%) were not different between the HOL and endostapler groups (P>0.05); however,
perforated appendicitis was more common in the endostapler group than the HOL
group (29.8% vs. 11.1%, P=0.027).
Operative time (mean+/-sd, 43.3+/- 15.8 min vs. 38.8+/- 20.5 min, P=0.247) and
intraoperative blood loss (mean+/-sd, 13.2+/-36.6 ml vs. 7.29 +/-9.1 ml, P=0.290) were
not different between the two groups. Drain placement (4.4% vs. 8.5%, p=0.430),
return to the hospital (2.2% vs. 10.6%, p=0.102), and longer hospital stay (mean+/-sd;
1.8+/- 1.32 days vs. 2.5 days +/-2.76, p=0.111) were more common in the endostapler
group, but did not reach statistical significance. Postoperative complications were more
common in the endostapler group (19.2% vs. 2.2%, p=0.009).
In multivariate analysis, the HOL clip was associated with a lower complications rate
(OR=0.05, 95% CI 0.003-0.744; p=0.030). In propensity score matched cohort with
balanced preoperative characteristics including the rate of perforated appendicitis,
the HOL group still had lower postoperative complications (15.8% vs. 2.6%). In a
subgroup analysis of 77 patients with non-perforated and non-gangrenous appendicitis,
postoperative complications were lower in the HOL group but that did not reach
statistical significance (6.1% vs. 0%, P=0.114).
Conclusion: Use of the HOL clip in LA is safe, effective and less costly than using
the endostapler. The HOL clip use might be associated with decreased postoperative
complications after LA.

*+22. FULL PATHOLOGICAL REVIEW OF ALL GASTRIC REMNANTS
FOLLOWING SLEEVE GASTRECTOMY: IS IT NECESSARY?
SK Hansen MD, BJ Pottorf MD, HW Hollis Jr MD, FA Husain MD
Denver, CO
Background: Obesity is now emphasized as a major health concern in the United
States. Current estimates show that over 50% of adults are overweight or obese; 6%
of the population qualifies as morbidly obese based upon body mass index (BMI
>40). Obesity has been proven to increase medical co-morbidity and mortality. To
date, the most successful treatment for obesity remains bariatric surgical intervention.
Sleeve gastrectomy has become a popular choice for the morbidly obese patient. Many
institutions across the country send the gastric remnant for full pathologic review.
This study attempts to determine if enough pathological abnormalities exist in these
remnants to warrant full pathologic evaluation in each instance.
Method: Data on patients presenting for elective sleeve gastrectomy between Aug
1, 2011 and June 30, 2014 were collected. All pathology results were reviewed. Any
abnormality noted on pathology report was documented. Significant abnormalities
(those requiring continued follow up or treatment) were documented separately. All
procedures were performed by a fellowship trained surgeon.
Results: A total of 385 patients comprised the study population. Full pathologic
evaluation, performed by credentialed pathologists, was available for 352 patients
(91.4%). One hundred and fifteen (115/352) were noted to have abnormal pathology
(32.7%). Chronic gastritis or inflammation was the most common abnormality, noted
in 95 (27%) specimens. Other abnormalities were noted in 19 specimens (5.4%). These
included: benign polyps, which were identified in 8 (2.3%), and active gastritis or
inflammation was noted in 7 (2.0%) specimens. Active H. Pylori infection was also
present in 7 (2.0%) specimens. Intestinal metaplasia was identified in only 6 (1.7%)
specimens and no dysplasia or frank malignancy was recognized in any specimen.
Conclusion: Bariatric surgery remains the gold-standard for the treatment of obesity
and its comorbidities. Of the effective surgical options, sleeve gastrectomy has increased
in popularity. Many institutions send all gastric remnants for full pathologic analysis
at a cost ranging from $500 to $1500 per specimen (in our institution). These data
suggest that this practice is not necessary. None of the 352 patients in this retrospective
cohort analysis showed pathological findings requiring treatment or continued followup. In an era of exponentially increasing healthcare costs these results suggest that
routine pathologic evaluation of the gastric remnant following sleeve gastrectomy is
unnecessary, particularly when gross pathology is not noted at initial operation. In high
risk or symptomatic patients, preoperative EGD may be warranted if gastric pathology
is suspected. In average risk patients, back table examination of the remnant at the time
of surgery, with full pathologic review if an abnormality is noted, appears to be both
safe and present significant cost savings.

*23. LAPAROSCOPIC COMMON BILE DUCT EXPLORATION VERSUS
ERCP FOR THE MANAGEMENT OF CHOLEDOCHOLITHIASIS FOUND AT
TIME OF LAPAROSCOPIC CHOLECYSTECTOMY: ANALYSIS OF A LARGE
INTEGRATED HEALTH CARE SYSTEM DATABASE
MA Al-Temimi MD MPH, EB Kim MD, BA Chandrasekaran MD, CN Trujillo MD,
VJ Franz MD, SD Johna MD MACM, DJ Santos MD
Fontana, CA
Background: Endoscopic retrograde cholangiopancreatography (ERCP) after
laparoscopic cholecystectomy (LC/ERCP) and laparoscopic common bile duct
exploration (LCBDE) are acceptable interventions for the management of
choledocholithiasis that is found at time of LC, however, LCBDE can potentially
decrease the number of procedures and cost and shorten hospital length of stay. This
study will use data from large integrated urban/suburban health care system to compare
the safety and effectiveness of LCBDE to LC/ERCP in patients with cholidocholithiasis
found at time of LC.
Method: All patients with LC and choledocholithiasis found on intraoperative
cholangiogram (IOC) with no preoperative ERCP were identified in the Southern
California Kaiser Permanente database between January 2005 and September
2015. Those undergoing LCBDE during the study period (N=105) were compared
to consequent cases of those undergoing LC/ERCP between September 2014 and
September 2015. Failure was defined as the inability to clear the common bile duct on
cholangiogram, readmission with retained stones within 1 year, or conversion to open
surgery. Success of clearing the common bile duct is the primary outcome of the study.
Hospital length of stay, intraoperative events, and postoperative complications were the
secondary outcomes. Bivariate and multivariate analysis was used to test the association
of type of intervention with the primary and secondary outcomes.
Results: During the study period, 5,046 patients had LC with IOC and no
preoperative ERCP. Out of 1,372 who had choledocholithiasis on IOC and met our
inclusion criteria, 300 patients were included in the study (105 LCBDE, 195 LC/
ERCP). Mean age was 47.5+/-20 years and 74.7% were females. Patients undergoing
LCBDE were more likely to have American Society of Anesthesiologists (ASA) class
>3 (28.6% vs. 17.4%, p=0.025) and history of roux-en-y gastric bypass (16.2% vs.
0%, P<0.001). LC/ERCP was significantly more effective at clearing the common bile
duct than LCBDE (98.9% vs. 89.5%, p = 0.01), however, LCBDE was associated with
lower number of procedures per patient (mean+/- standard deviation (sd), 1.1+/-0.4 vs.
2.0+/-0.12, p<0.001). There was no mortality. 30-day postoperative morbidity (6.7% vs.
7.2%), hospital length of stay (mean+/-sd, 3.5+/-2.4 day vs. 3.4+/-2.6 day), readmission
to the hospital, return to the operating room, conversion to open surgery and number
of retained stones were not different between LCBDE and LC/ERCP (P>0.05). Two
patients failed ERCP and underwent open CBD exploration, while 11 patients failed
LCBDE and had subsequent ERCP. All patients with roux-en-y gastric bypass had
successful LCBDE.
Conclusion: LC/ERCP is superior to LCBDE at clearing common bile duct stones in
a large integrated health care system, however, LCBDE is an effective alternative when
ERCP cannot be used due to roux-en-y gastric bypass.

24. A NATIONWIDE EVALUATION OF ROBOTIC VENTRAL HERNIA
SURGERY
KM Coakley DO, SM Sims MD, T Prasad MA, AE Lincourt PhD MBA, VA
Augenstein MD, R Sing MD, BT Heniford MD, PD Colavita MD
Charlotte, NC
Background: Robotic surgery offers technical advantages to traditional laparoscopic
surgery, however, this technology comes at greater cost. Our purpose was to examine
outcomes of robotic versus laparoscopic surgery using a comprehensive national
database.
Method: The Nationwide Inpatient Sample, which captures ~20% of US inpatient
admissions, was queried from October 2008 (inception of the robotic ICD-9-CM
code) to December 2013 for ventral hernias, defined as incisional, umbilical, epigastric,
hypogastric, and spigelian. Demographics, morbidity, mortality, and costs were
compared between robotic and laparoscopic techniques.
Results: From 2008-2013, 149,622 ventral hernia surgeries were identified; 117,028
open, 32,243 laparoscopic, and 351 robotic. Robotic use rose annually with 2013 alone
having 168 (47.9%) of all the robotic ventral hernias for the study period. Robotic
patients were more likely to be older (59.4 ±14.6 years vs 57.4±14.9 years; p=0.01) and
have more chronic conditions (3.8±2.7 vs 3.4±2.6; p=0.007). When comparing robotic
and laparoscopic groups, there was no difference between length of stay (3.5±3.6 vs
3.4±2.6, p=0.2). Pneumonia rates were higher in the robotic group (4.3% vs 2.4%
p=0.02); however, mortality and other major complications (CHF, renal failure, MI,
wound dehiscence, stroke, PE, ARDS, shock) were the same between laparoscopic and
robotic ventral hernias. Total charges were increased for the robotic group ($61,274.5
± $42,666.7 vs $38,715.2 ± $28,533.74; p<0.0001), and robotic technique was more
likely to be performed in zip codes with the highest median income,≥$64,000, (28.6%
vs 22.9% p=0.014). Robotic ventral hernias were more likely to be performed in urban
teaching hospitals (57.3% vs 48.2%; p=0.0007) and regionally the South had the
highest rate of robotic utilization (45.0% vs 38.1%, p=0.008).
Using multivariate regression, when controlling for age, number of chronic conditions,
hospital geographic region, public versus private hospital type, urban versus rural
teaching status, and zip code median income, robotic repair remained an independent
predictor of increased charges ($42,120± $257.1 vs. $61,458.9± $1431.0; p<0.0001)
Conclusion: The first nationwide evaluation of robotic ventral hernia repair
demonstrates comparable safety to the laparoscopic technique, with increased cost
and regionalization to urban teaching hospitals in areas of higher median income. The
results of this nationwide evaluation continue to demonstrate robotics’ higher costs
compared with conventional laparoscopy.

*25. DISPARATE EFFECTS OF CATECHOLAMINES UNDER STRESS
CONDITIONS ON ENDOTHELIAL GLYCOCALYX INJURY: AN IN VITRO
MODEL
JV Martin MD, LN Diebel MD, DM Liberati MS
Detroit, MI
Background: Geriatric trauma patients have high circulating norepinephrine (NE)
levels but attenuated release of epinephrine (Epi) in response to increasing severity
of injury. Sympathoadrenal activation and tissue hypoxia secondary to trauma
induce endothelial activation and glycocalyx injury, which are major factors in the
pathogenesis of the acute coagulopathy of trauma. Elderly patients also have a greater
proclivity to a post injury hyperfibrinolytic phenotype; however the pathogenesis is
unknown. To account for these findings, we hypothesized that NE and Epi ± hypoxia
have different effects on the endothelial and glycocalyx components of the vascular
barrier and were studied in vitro.
Method: Confluent human umbilical vein endothelial cells (HUVEC) were treated
with varying concentrations of NE or Epi and exposed to hypoxia-reoxygenation (H/R;
5% CO2 95% N2) or standard culture conditions (21% O2, 5% CO2). Cell culture
supernatants were obtained and glycocalyx injury indexed by syndecan-1 release and
endothelial cell activation/injury determined by soluble thrombomodulin (TM),
plasminogen activator inhibitor-1 (PAI-1), and tissue type plasminogen activator (tPA)
concentrations (all by ELISA).
Results: See table
Conclusion: NE ± H/R was associated with significantly greater glycocalyx damage
and endothelial activation/injury vs. Epi treatment groups. There were minimal
changes in PAI-1 with either NE or Epi ± H/R. However NE ± H/R was associated
with significantly higher tPA levels, reflective of a profibrinolytic state. Our study
supports the more liberal use of the anti-fibrinolytic agent tranexamic acid in the
severely injured elderly patient population.

IMAGING METRICS IMPROVE INJURY PREDICTION
MC Johnson MD, R Stewart MD, D Jenkins MD, J Myers MD, D Dent MD, L Liao
MD, R Cestero MD, S Nicholson MD, M Muir MD, E Scherer MD, C Crane MD, B
Eastridge MD
San Antonio, TX
Background: The abdominal seatbelt sign (ASBS) has an established association with
abdominal injury, yet its definition remains ill-defined. The goal of our study was to
better characterize abdominal seatbelt sign in the context of seatbelt wear pattern. We
hypothesize specific imaging characteristics associated with the ASBS such as location
above the pelvic brim and depth of abdominal wall soft tissue injury would better
predict underlying injury and need for operative intervention.
Method: We performed a retrospective chart review of all motor vehicle crashes
(MVC) evaluated at a level one trauma facility from 2010-2015. Inclusion criteria
included age >17, MVC mechanism, diagnosis of abdominal wall contusion, and
availability of CT imaging. The population was refined by documentation of an
“abdominal seat belt sign” in the medical record. Variables collected for the analysis
included demographics, intraperitoneal injuries, pelvic fractures, injury severity score,
operative procedures and outcomes. CT imaging was reviewed for the presence of a
transverse abdominal wall contusion consistent with lap belt use. Contusion location
was determined in relation to the anterior superior iliac spine (ASIS). Abdominal
wall thickness as well as contusion depth were measured at the contusion level and an
abdominal seatbelt sign depth index (ASBSI) was calculated.
Results: Sample size for the cohort was 333 subjects, of which 111 had evidence of
seatbelt sign on CT imaging and 163 had evidence of seatbelt sign only on exam.
Operative need was 7.4% in those with ASBS on CT (CT ASBS) and 2.8% in those
with only clinical evidence of ASBS (CL ASBS). CT ASBS above the ASIS was
associated with higher incidence of intra-abdominal injuries (33.3% vs 18.5%; p =0.07)
and a higher rate of abdominal operations (24.6% vs. 7.4%; p < 0.01) compared to
below the ASIS. In contrast, CT ASBS below the ASIS was associated with a higher
incidence of pelvic fractures (24.1% vs. 5.3%; p<0.005). Calculation of the associated
risk ratios for abdominal exploration noted those with CL ASBS were 1.17 times more
likely to need an abdominal operation while those with CT ASBS were 2.12 times more
likely to require intervention. Evaluating subjects with CT ASBS above the ASIS, those
requiring operative intervention were associated with seatbelt signs higher above the
ASIS (5.07 vs 3.21 cm; p- 0.01) and a deeper ASBSI (0.91 vs 0.57; p <0.001). Applying
these metrics to predict the need for operative intervention demonstrated that ASBSI
was significantly associated with abdominal injury requiring operative intervention
(Figure 1).
Conclusion: Characteristics of the abdominal wall injury on CT imaging such as
location above the ASIS and injury depth index are better predictors of abdominal

*27. NOT EVERY TRAUMA PATIENT WITH A RADIOGRAPHIC HEAD
INJURY REQUIRES TRANSFER FOR NEUROSURGICAL EVALUATION:
APPLICATION OF THE BRAIN INJURY GUIDELINES TO PATIENTS
TRANSFERRED TO A LEVEL 1 TRAUMA CENTER
G Capron MD, DB Wall MD
Urbana, IL
Background: Regional trauma protocols and local custom require all patients with
radiographically-identified traumatic brain injuries to be transferred to our level
1 trauma center for neurosurgical evaluation. However, few injuries ultimately
require neurosurgical intervention. Furthermore, in our rural area, transfer is costly,
inconvenient, and potentially risky in inclement weather. Joseph, et al have previously
validated within their own institution Brain Injury Guidelines (BIG) to identify
patients with head injuries who can be safely managed solely by acute care surgeons.
We propose that these guidelines may be useful in helping to determine which patients
could safely avoid mandatory transfer to a regional trauma center for neurosurgical
evaluation.
Method: All patients transferred to our level 1 trauma center with a diagnosis of
head injury between January 2012 and December 2013 were identified. Patients
without a radiographically-identified intracranial bleed or skull fracture, as well as
those with severe non-cranial injuries that mandated transfer, were excluded. The
remaining 340 patients were classified as BIG 1 (minor head injury-46 patients), BIG
2 (moderate head injury-59 patients), and BIG 3 (severe head injury and all patients
on anticoagulation-235 patients) according to Joseph, et al’s guidelines. Patient
characteristics and outcomes were compared.
Results: When compared with BIG 3 patients, BIG 1 and 2 patients were significantly
younger. BIG 2 patients were more likely to be intoxicated. BIG 1 and 2 patients had
a significantly higher GCS, lower Injury Severity Score, and shorter length of hospital
stay and ICU stay than BIG 3 patients. BIG 3 patients were significantly more likely
to require a neurosurgical procedure and to die. No BIG 1 patients deteriorated or
required neurosurgical intervention. One BIG 2 patient required lumbar peritoneal
shunt placement for prolonged cerebrospinal fluid leak after basilar skull fracture and
another required readmission 9 days after hospital discharge for an enlarged subdural
hematoma that was managed nonoperatively. In the BIG 3 group, 28 patients (11.9%)
required neurosurgical procedures and 47 (20%) died.
Conclusion: The BIG classification proposed by Joseph, et al can help stratify
patients for whom transfer is considered. BIG 1 patients have a minimal probability
of neurologic deterioration and could potentially be safely observed at their local
facility without transfer. In contrast, BIG 3 patients potentially need neurosurgical
intervention and should be transferred. BIG 2 patients have a small probability of
deterioration or of requiring neurosurgical intervention and the decision to transfer
should be individualized.

INTENSIVE CARE UNIT MONITORING
JC Perumean MD, M Martinez BS, R Neal BS, J Lee BS, B Wiliams MD, S Wolf MD,
H Phelan MD
Dallas, TX
Background: The standard of care for nonoperative management of blunt hepatic
injuries (BHI) is intensive care unit (ICU) observation. It remains unknown if
subpopulations of BHI exist which can be safely observed in a non-ICU environment.
We sought to determine which low-grade hemodynamically normal BHI at first
presentation to the emergency department were associated with any of three
interventions indicating ICU observation.
Method: We reviewed all BHI admitted to our urban, level 1 trauma center between
01/01/96 and 6/30/14, collecting information on packed red cell (PRC) transfusions,
imaging, hepatic angiography, laparotomy, associated injuries, and cause of death.
Two groups were created: Group A (hepatic injury grades 1-3 with normal first systolic
blood pressure (hemodynamically normal) and Group B (all other BHI). Interventions
traditionally undergoing ICU observation were defined as any with the following three
criteria: PRC transfusion within the first 24 hours, hepatic angiography, or all-cause
laparotomy. Outcomes between Groups and within Group A subgroups were collected.
Fischer’s exact was used for categorical data and t-tests for continuous data.
Results: Group A (n=838) had a significantly lower ISS, shorter length of stay, fewer
units of PRCs transfused, and lower mortality (all p<0.01) than Group B (n=331).
Interventions in Group A by grade subgroup are listed in Table 1. Hemodynamically
normal low grade injuries had a negative predictive value of 77.42% for any of the three
interventions that warranted ICU admission. Sensitivity/specificity of the criteria for
ICU admission were 46.53% and 73.49%, respectively. Laparotomy specifically for
management of BHI was low in both groups (1.9% in the Grade I/II subgroup and
4.3% in the Grade III subgroup). For patients with isolated BHI (n=156), the sensitivity
and specificity of the three interventions was 13% and 90%, while the NPV had a
small increase to 81%.
Conclusion: Hemodynamic stability at presentation is insufficiently sensitive as a sole
criterion for safe admission of Grade I-III BHI to a non-ICU environment.

29. OPERATIVE VERSUS NON-OPERATIVE MANAGEMENT IN THE CARE
OF PATIENTS WITH COMPLICATED APPENDICITIS
TS Helling MD, DF Soltys MD, S Seals PhD
Jackson, MS
Background: While there is some evidence that antibiotic therapy alone for
uncomplicated appendicitis may be sufficient therapy in a majority of patients,
the approach to complicated appendicitis, defined as evidence of perforation, periappendiceal abscess, or phlegmon, is less clear. We have sought to determine whether
early surgery or antibiotic therapy would be the preferred treatment for this group of
patients
Method: All adult patients (> 18 years old) admitted to a university hospital over
a five-year period 2009 – 2014 with a diagnosis of appendicitis were reviewed. The
majority of patients received a CT scan for diagnosis. The patients were grouped into
uncomplicated and complicated presentations. Operative management during the
index hospitalization was identified using specific CPT codes. The absence of these
codes was presumptive evidence of non-operative management. The patients were
stratified into age, gender, ethnicity, and socio-economic status by virtue of income
and payer source. Mortality, morbidity, length of hospital stay (LOS), readmission,
and hospital charges were used as outcome measures. Analyses utilized univariate and
multivariate methodology.
Results: Over the study period 611 adult patients were admitted with the diagnosis
of appendicitis. Of those 306 patients (50 percent) presented in an uncomplicated
manner, and 305 patients (50 percent) were complicated presentations. Complicated
presentations were more often seen in older patients (p < 0.001) and in white
ethnicity (p = 0.002). Overall, patients who underwent surgery for their appendicitis
(complicated or uncomplicated) experienced a lower rate of complications (OR = 0.33,
p = 0.0066), and in the complicated groupings, those who were treated non-operatively
had significantly more morbidity (OR = 6.94, p = 0.0005). There was a trend, but no
statistical significance, towards lower mortality in those patients with complicated
presentation who had surgery (OR = 0.23, p = 0.566). Length of hospital stay was
significantly longer for complicated patients treated non-operatively (OR = 4.37 versus
2.56, p < 0.0001) and they required more readmissions compared to uncomplicated
patients undergoing immediate appendectomy (OR = 6.84, p < 0.0001). By
multivariate analysis LOS and rate of hospital readmissions were significantly affected
in complicated patients treated operatively compared to those complicated patients
treated non-operatively (OR = 4.21 versus 2.33, p < 0.001; OR = 7.19, p < 0.001).
Conclusion: From this single center retrospective study it appears that the early,
operative treatment of patients presenting with complicated or uncomplicated
appendicitis is preferable to non-operative, antibiotic oriented treatment. Moreover,
the operative treatment of complicated appendicitis compared to non-operative
management reduced morbidity, LOS, and hospital readmission, all of which impact
cost of care.

UNCOMPLICATED RADIOGRAPHIC REDUCTION OF PEDIATRIC
INTUSSUSCEPTION
MU Mallicote MD, MA Isani MD, AS Roberts, MD, NE Jones BS, KA Bowen MD,
RV Burke PhD, JE Stein MD, CP Gayer MD, PhD
Los Angeles, CA
Background: Routine hospital admission for the management of pediatric ileocolic
intussusception has previously been done following successful radiographic reduction
due to the concern of possible early recurrence (≤48 hours). However, due to the low
recurrence rates we created a new institutional protocol starting 02/05/2014 in which
routine admission was eliminated. Patients were observed in the ED and discharged
2-4 hours after nonsurgical reduction provided they were afebrile, tolerating liquids,
and did not have tachycardia or abdominal pain. We hypothesize that this protocol is
safe and will reduce hospital cost/resources.
Method: IRB approval was obtained and we conducted a retrospective review of
pediatric patients who presented with intussusception between 01/01/2011 and
02/15/2016. Each patient was identified as being managed under the old protocol
versus those managed under the new protocol (implemented 02/05/2014). Outcomes
measured included early recurrence vs. later recurrence, length of stay, and adverse
outcomes. Patients requiring surgery at first presentation were excluded. Chi-square
and Student’s t-tests were used for analysis, as appropriate. ROUT analysis was used to
remove outliers.
Results: 132 patients were identified as having been treated for intussusception during
the study period. 57 were managed with the new protocol and 75 were managed with
the old protocol. Mean age for both protocols was 1.4 years. Recurrence rates were
similar for both protocols with the new having early recurrence rates (≤48 hours) of
5.97% (n=4, mean=18.25 hours) and later recurrences rates (>48 hours) of 8.96%
(n=6, avg 73 days) versus the old which had early recurrence rates of 4.65% (n=4, avg
32.88 hours) and later recurrence rates of 8.14% (n=7, mean=94 days). Average time
to early recurrence between old and new (t-test, p=0.1824, n=4) and later recurrence
(t-test, p=0.5390, n=6) were not statistically significant. Total recurrence rates for the
new protocol were 14.93% (n=10) with a mean of 44 days versus the old protocol of
12.79% (n=11) with a mean of 66 days. 1 patient from the new and 3 patients from the
old protocol underwent surgical management for their recurrence. The average length
of stay for patients observed in the ED under the new protocol was 5.4 hours, while
those admitted for observation under the old protocol was 27.9 hours without adverse
outcomes.
Conclusion: Discharging patients following uncomplicated radiographic reduction of
ileocolic intussusception that meet strict clinical criteria after a 2-4 hour observation
period is as safe as admitting them for a 24 hour observation period. However,
recurrence remains a possibility and families should be educated about both early and
later recurrence. Shorter hospital observation does not appear to lead to an increase
in adverse events, and larger trials will need to be conducted to help identify clinical
predictors of recurrent intussusception.

INCIDENTAL PAPILLARY THYROID CANCER CAN BE PERFORMED
SAFELY
CM Hall MD, DC LaSeur MD, SK Snyder MD, TC Lairmore MD
Temple, TX
Background: Extent of cervical lymphadenectomy for papillary thyroid cancer
(PTC) remains controversial, especially after an incidental finding of PTC following
thyroidectomy. Although level VI metastases are associated with increased recurrence
rates, central lymph node dissection (CLND) is often reserved for patients with
clinically positive lymph nodes or cancer recurrence. The purpose of this study is to
compare the pathological outcomes and operative morbidity for patients undergoing
a primary total thyroidectomy with CLND, to those patients undergoing an interval
CLND following a previous incomplete thyroid operation, or for unsuspected diagnosis
of cancer determined on final pathology.
Method: A single-institution, retrospective review of all patients undergoing
surgical treatment for PTC from 2000-2015 was performed under an IRB-approved
protocol. Patients were divided into three treatment groups: total thyroidectomy with
concurrent primary CLND, interval prophylactic CLND, and interval therapeutic
CLND. Primary outcomes were number of lymph nodes removed, permanent
hypoparathyroidism and recurrent laryngeal nerve (RLN) injury.
Results: Results for 73 patients undergoing interval CLND (33 prophylactic, 40
therapeutic) were compared with 218 patients undergoing primary total thyroidectomy
with CLND. Demographics and primary outcomes are shown in Table 1. Interval
CLND was associated with similar and acceptable complication rates, including RLN
injury and permanent hypoparathyroidism. Interval CLND was associated with a trend
towards decreased lymph node recovery. Positive level VI lymph nodes were identified
in 27% of patients undergoing an interval prophylactic CLND.
Conclusion: Re-operative (interval) CLND in patients with an initial incomplete
thyroidectomy, or unsuspected diagnosis of cancer revealed on final pathology, can be
performed with acceptable morbidity but may be associated with decreased lymph node
recovery. Interval CLND should be considered in patients with incidental PTC due to
the incidence of occult level VI lymph node metastases. We recommend routine CLND
at the primary operation when the diagnosis of PTC is known.

32. WHAT HAPPENS AFTER A FAILED LIFT FOR ANAL FISTULA?
ME Wright MD, AG Thorson MD, GJ Blatchford MD, M Shashidharan MD, JS
Beaty MD, NL Bertelson MD, P Aggrawal MD, L Taylor PAC, CA Ternent MD
Omaha, NE
Background: Anal fistula is a complex disease process that can sometimes be
frustrating to treat. The main tenets of treatment are control of sepsis, closure of the
tract, and maintenance of continence. There have been many treatments developed
over the years, but one of the most recent is Ligation of Intersphincteric Fistula Tract
(LIFT). This procedure preserves the sphincters by going between them to locate the
fistula tract and close it. It has been described as easy to learn and has an 70 to 90%
success rate. The aftermath of a failed LIFT has not been well documented.
Method: Retrospective chart review of patients undergoing LIFT procedure (CPT
46275) for transsphincteric anal fistula between March 2012 and September 2016.
Patient demographics, previous fistula surgeries, time to healing, time to recurrence,
and any subsequent procedures and results were recorded. Statistical analyses were
performed with Fisher’s Exact Test, Chi-square Test and Mann-Whitney U Test.
Results: 52 patients with LIFT procedures were identified, 16 of whom developed
fistula recurrence(30%) at a mean follow up time of 7.7 months. The mean time to
fistula recurrence after LIFT was 4.4 months. Demographic features between the two
groups did not show a significant difference(TABLE 1). Following LIFT, recurrence
of fistula was transsphincteric and intersphincteric in 50%(8/16) and 31%(5/16),
respectively(p=NS) in patients with available follow up. Eleven of 16 patients with
fistula recurrence following LIFT underwent further surgery, four were lost to follow
up and one is pending surgery. Persistent transsphincteric fistulas after LIFT were
treated with seton replacement in 83%(5/6) followed by rectal advancement flap in
33%(2/6) and second stage fistulotomy in 33%(2/6) at a mean time of 11 months
(range: 9-13 months). One transsphincteric fistula recurrence after LIFT treated
without seton replacement underwent closure of the tract with fibrin glue. Of the 5
recurrent intersphincteric fistulas 3 underwent seton replacement (60%) followed by
second stage fistulotomy, advancement flap, or seton replacement. One patient with
intersphincteric fistula recurrence went directly to fistulotomy (1/5) and one was lost to
followup. Of these 11 patients who underwent further surgery after failed LIFT, 45%
had resolution of the fistula. Among those patients with documented healing, 80%
had seton followed by fistulotomy, while the remaining 20% had a seton followed by
advancement flap.
Conclusion: The results of this study are consistent with previously published data
indicating a success rate of 70-90% for LIFT. None of the factors studied in this group
demonstrated a significant difference between patients who did or did not develop a
documented recurrence after LIFT. Once patients recurred, further LIFTs were not
undertaken. Among patients who undergo further surgery, healing was achieved in
45%.This study shows that the most successful treatment of recurrent fistula after LIFT

*33. THE HYPERCOAGULABILITY OF END STAGE RENAL DISEASE: THE
ROLE OF FIBRINOGEN
GR Nunns MD, EE Moore MD, MP Chapman MD, HB Moore MD, GR Stettler
MD, E Peltz DO, CC Burlew MD, C Silliman MD PhD, A Banerjee PhD, A Sauaia
MD PhD
Aurora, CO
Background: End Stage Renal Disease (ESRD) patients are prone to both
increased rates of bleeding as well as thrombosis. We have previously conducted
thromboelastography (TEG) to characterize the coagulation status in ESRD patients,
observing delayed clot formation (Activated Clotting Time, ACT) and increased
final clot strength (Maximum Amplitude, MA). In healthy individuals, the platelets
contribution to clot strength is 80% while fibrinogen contributes 20%. However, in
patients with ESRD the cause of increased clot strength is not understood. Given
the known platelet dysfunction and hyperfibrinogenemia associated with ESRD, we
hypothesize that the increase in clot strength in ESRD correlates with increased serum
fibrinogen levels. In addition, we investigated the role of fibrinolysis in ESRD.
Method: 58 ESRD patients underwent simultaneous citrated rapid TEG (rTEG) and
determination of serum fibrinogen levels prior to operative creation of dialysis access.
These were compared to 135 healthy controls that underwent rTEG. TEG variables
examined were ACT, angle, MA, and percent clot lysis at 30 minutes (LY30). Data
are presented as median and interquartile range (IQR). Cluster analysis identified
subgroups with unique TEG profiles. Correlations were assessed via Spearman Rho.
Results: Patients with ESRD and healthy controls demonstrate statistically significant
differences in ACT (121 (IQR: 105-136) vs 113 (IQR: 105-121) seconds, p=0.0004),
Angle (78.8 (IQR: 75.8-81.1) vs 73.9 (IQR 70.9-76.3) degrees, p<0.0001), MA (70.4
(IQR: 66.6-74.2) vs 65 (IQR 61.5-68) mm, p<0.0001) and LY30 (1.3 (IQR: 0.2-2.4) vs
2.7 (IQR 2.0-3.7) percent, p<0.0001). Cluster analysis revealed 3 subgroups of patients,
which explained over 75% of the variation: 1) Predominant fibrinolysis shutdown
phenotype (LY30 =<0.8%, n= 37); 2) Predominant physiologic fibrinolysis phenotype
(LY30 0.8-2.9%, n=10); 3) Predominant hyperfibrinolysis phenotype (LY30 >=3%,
n=10). Fibrinogen levels were elevated in ESRD patients (median 434 (IQR 338-535)
mg/dL) compared to the clinical reference range (150-400 mg/dL) and positively
correlated with MA (Rho = 0.67, p<0.0001) and Angle (Rho = 0.32, p<0.01) in ESRD
patients.
Conclusion: A unique coagulopathy exists in patients with ESRD consisting of
delayed clot formation, but increased final clot strength and decreased clot breakdown.
Additionally, a small subgroup with increased clot breakdown was identified. These
findings provide insight into the dichotomous clotting and bleeding seen in ESRD. The
existence of a subgroup of patients with increased clot breakdown suggests a population
susceptible to hemorrhage. At the same time, stronger clots that are resistant to
breakdown, may be a contributing factor towards the increased incidence of thrombosis

seen in the ESRD population. This increased clot strength appears to be mediated
through hyperfibrinogenemia. Therefore, strategies to ameliorate hypercoagulability in
ESRD should target fibrinogen.

QS 1. MANAGEMENT AND OUTCOMES OF CHOLECYSTECTOMY IN
PREGNANCY
RP Won MD, S Friedlander MPH, SL Lee MD
Torrance, CA
Background: Cholecystitis is a common surgical emergency during pregnancy.
Cholecystectomy is the treatment of choice in pregnant women due to significant
recurrence and morbidity associated with non-operative management. Given the
limited data in this patient population, our objective was to determine the presentation,
management practices, and outcomes of cholecystectomy during pregnancy.
Method: The California State Inpatient Database was queried for all women age
15-45 requiring cholecystectomy for acute and chronic cholecystitis in 2005-2011
(n=102,966). Hierarchical and multivariate regression analyses were used to compare
primary outcomes including laparoscopy, morbidity, length of stay, and cost in
pregnant and non-pregnant women. Rates of prematurity and fetal loss in patients
undergoing cholecystectomy were also compared to baseline rates in all pregnant
women from 2005-2011 (n=3,084,964).
Results: Of the 102,966 cholecystectomies performed, 5,763 (5.6%) were in pregnant
women and 97,203 (94.4%) were in non-pregnant women. On univariate analysis, rates
of laparoscopy (pregnant=95.5% vs. non-pregnant=94.5%, p<0.01) and non-pregnancy
related complications (pregnant=2.5% vs. non-pregnant=3.3%, p<0.01) appeared
clinically similar despite reaching statistical significance. Univariate analysis also
revealed pregnant women had a longer length of hospitalization (3.4 days vs. 3.1 days,
p<0.01) and higher costs ($11,510 vs. $11,099 dollars, p<0.01). Multivariate analysis
confirmed pregnant and non-pregnant women had similar rates of non-pregnancy
related complications (RR 0.89, 95% CI 0.72-1.05, p=0.15). Multivariate analysis also
confirmed pregnancy contributed to increased total cost (median difference $509, 95%
CI $54-$963, p=0.03), despite showing no difference in length of hospitalization (RR
1.00, 95% CI 0.97-1.04, p=0.95). Compared to baseline rates in pregnancy, patients
undergoing cholecystectomy had similar rates of fetal loss (0.51% with cholecystectomy
vs. 0.43% without cholecystectomy, p=0.50), but higher rates of pre-term delivery
(9.9% vs. 6.2%, p<0.01; RR 1.07, 95% CI 1.02-1.13, p=0.01).
Conclusion: Cholecystectomy was safe during pregnancy with similar rates of
maternal, non-obstetric morbidity. Pregnancy did not preclude use of laparoscopy and
was performed with similar overall costs. Although cholecystectomy did increase risk of
prematurity, these risks were marginal and acceptable given the potential morbidities of
non-operative management.

QS 2. PREDICTORS OF FAILED TRANSCYSTIC LAPAROSCOPIC
COMMON BILE DUCT EXPLORATION: A MULTICENTER INTEGRATED
HEALTH SYSTEM EXPERIENCE
MA Al-Temimi MD MPH, EB Kim MD, BA Chandrasekaran MD, CN Trujillo MD,
AF Mousa BA, DC Santos MD, SD Johna MD MACM
Fontana, CA
Background: Transcystic laparoscopic common bile duct exploration (TLCBDE) is
generally more favorable than laparoscopic choledochotomy (LCD), however, some
anatomical characteristics might preclude performing TLCBDE. The characteristics
for successful TLCBDE in the literature were mostly derived from expert opinion. The
purpose of this study is to report cases of LCBDE from a large integrated health system
and identify anatomical predictors of failed TLCBDE.
Method: This is a retrospective study (2005-2015) of all patients who underwent
laparoscopic common bile duct exploration (LCBDE) at thirteen Kaiser Permanente
Southern California Medical Centers. Patient demographics, preoperative
comorbidities, intraoperative imaging and preoperative laboratory findings were
reviewed. Intraoperative details and postoperative course and complications were
reported. Failure was defined as inability to clear the common bile duct (CBD),
retained stone or conversion to open procedure. In a subset analysis of predictors of
failed TLCBDE, failure was defined as inability to clear the CBD. Predictors of failed
TLCBDE were identified using univariate and multivariate analysis.
Results: Out of 3,650 patients diagnosed with choledocholithiasis during the study
period, 120 (3.2%) underwent LCBDE. Of those, 15 cases were done after failed
ERCP and 17 patients had roux-en-y gastric bypass. TLCBDE (89.2%) was more
commonly performed than LCD (10.8%). Mean patient age was 52.6 years and the
majority were females (74.2%). Average hospital length of stay was 3.8 days, which was
slightly shorter with the TLCBDE than LCD (mean+/-sd; 3.7+/-2.6 days vs. 4.8+/-2.7
days, p=0.153). There was no mortality and eight patients (7.5%) had postoperative
complications. Patients undergoing LCD had larger CBD (11.9+/-4.3 vs. 9.7+/-3.2,
p=0.03) and were more likely to be done in an elective setting (46.2% vs. 15%,
p=0.006) than TLCBDE. LCBDE was successful in 88.3% of cases (88.8% TLCBDE
vs. 84.6% LCD, p=0.658). Failed LCBDE was due to conversion to open in 2 cases,
equipment failure in 2 cases, need for intraoperative ERCP to visualize the proximal
bile duct in 2 cases, and failure to clear the common bile duct in 8 cases. To identify
predictors of failed TLCBDE, failure to clear the CBD was associated with cystic duct
tortuosity (25% vs. 4.3%, p=0.018) and larger common bile duct diameter (mean+/sd, 11.9 +/- 4.3 cm vs. 9.7 +/- 3.2 cm, p=0.044). There was a suggestive association of
stone size, stone size to cystic duct diameter ratio, presence of multiple stones, and stone
location with failure, however that did not reach statistical significance. In multivariate
analysis, only cystic duct tortuosity (OR=9.5, 95% CI 1.03-87.6) was associated with
failure of TLCBDE.
Conclusion: LCBDE is effective in the management of choledocholithiasis in patients
with roux-en-y gastric bypass or those who fail ERCP. Cystic duct tortuosity is an
independent predictor of failed TLCBDE.

QS 3. AN ACUTE CARE SURGERY MODEL IS ASSOCIATED WITH
DECREASED COSTS AND LENGTH OF STAY AFTER APPENDECTOMY

Bloom MD, H Sax MD, N Melo, MD
Los Angeles, CA
Background: Appendectomy remains as one of the most commonly performed surgical
procedures in the United States. With continued increase in operative expenses,
efforts to improve costs associated with appendectomy are important with the advent
of healthcare reform. Acute care surgery (ACS) services have been implemented in
many facilities nationwide as a surgical hospitalist model for the management and
intervention of urgent and emergent surgical cases such as appendicitis.
Method: From October 2012 to June 2016, data was prospectively collected on all
patients who underwent appendectomies at a large urban academic center with over
950 beds. Patients were divided into two groups, those who had an appendectomy
performed by the ACS service (surgical hospitalist, n=445) and those who had an
appendectomy by a non-ACS surgeon (including private practitioners, n=682). Primary
outcome measures were length of stay (LOS), costs, and readmission rates
Results: A total of 1,127 patients underwent appendectomies during the study period,
of those 445 (39.5%) were performed by the ACS service. Analysis of data revealed a
mean age of 36.1 in the ACS group vs. 44.4 for the non-ACS (p<0.001). There was a
significant difference in both total costs observed of $12,030 for the ACS group vs.
$15,697 for the non-ACS group (p<0.001) and direct institutional costs of $5,739 vs.
$7,549 for the non-ACS group (respectively, p<0.001). Length of stay was shorter for
the acute care surgery group at 2.1 days vs. 3.2 days for the non-ACS group (p<0.001).
There was no difference in readmission rates, of 0.02% (n=7) for the ACS group, vs.
0.03% (n=17) for the non-ACS group (p=NS).
Conclusion: Appendectomies performed by an acute care surgery, or surgical
hospitalist group led to decrease in total and direct hospital costs and decreased length
of stay, without any significant difference in readmission rate.

QS 4. OUTPATIENT LAPAROSCOPIC APPENDECTOMY MAY BE SAFE FOR
NON-PERFORATED GANGRENOUS APPENDICITIS
A Patel BA, CL Isbell MD, JL Regner MD, RW Smith MD, TS Isbell MD, B Hodges
RN, SW Abernathy MD, RC Frazee MD
Temple, TX
Background: Appendicitis is one of the most common surgical emergencies with
an annual incidence of 1 per 1000 of which 20% are perforated. Our institution has
managed simple appendicitis with outpatient laparoscopic appendectomy (OLA) since
2010. Recently the American Association for the Surgery of Trauma (AAST) developed
the Appendicitis Disease Severity Score (DSS) to assist with benchmarking outcomes.
We hypothesized that local severe appendicitis (with gangrene, AAST DSS 2 or local
perforation, AAST DSS 3) is clinically different than severe diffuse appendicitis (AAST
DSS 4 and 5).
Method: In 2014, we chose appendectomy as a targeted procedure for our participation
in the National Surgical Quality Improvement Program (NSQIP). Patients with
acute appendicitis were initially managed with OLA unless evidence of gangrenous or
perforated appendicitis was noted at the time of surgery. We compared AAST DSS 2-5
to determine if differences existed in demographic variables and length of stay (LOS).
Using our NSQIP targeted appendectomy data from July 2014 to June 2015 in the
Semi-Annual Report (SAR) and concurrent chart review for AAST DSS, the outcomes
for each group were analyzed and compared.
Results: Between July 2014 and June 2015, 152 patients underwent appendectomy for
acute appendicitis. The number of patients with each AAST DSS, demographics, and
length of stay (LOS) is seen in the Table. Most patients (8/10) with AAST DSS 2 were
discharged from day surgery, and none were discharged with antibiotics. Complications
overall were low. Per NSQIP, we had no SSIs (1st deciles) and 5 readmissions, two
related to the previous surgery (2nd decile). Wound occurrences were all considered
PATOS (present at time of surgery). When comparing all groups for complications, no
statistical differences could be found between any AAST DSS. No statistical differences
were noted for LOS between AAST DSS 3-5. Univariate analysis showed preoperative
sepsis/SIRS, AAST DSS, and age to be associated with longer hospital LOS. Median
hospital LOS for those admitted was 1 (IQR 1-2 days). Patients with a LOS of one day
or less had a median age of 33 years while patients with a LOS of two or more days had
a median age of 53 years. All patients who were admitted were treated with antibiotics
and discharged with antibiotics.
Conclusion: AAST DSS 1 and 2 can safely be managed as an outpatient. No LOS
differences are readily seen between AAST DSS 3-5 for perforated appendicitis. Future
studies are needed to pinpoint risk factors for longer hospitalization after perforated
appendicitis and development of best practice guidelines.

QS 5. EVALUATION OF NEGATIVE PRESSURE WOUND THERAPY TO
CLOSED LAPAROTOMY INCISIONS IN ACUTE CARE SURGERY
E Schurtz MD, J Differding MPH, E Jacobson MD, C Maki MD, M Ahmeti MD
Grand Forks, ND
Background: Surgical site infections are a major burden to the healthcare system
accounting for $1.6 billion in hospital care costs per year in the U.S. Negative pressure
wound therapy (NPWT) is an established treatment for non-healing wounds and
open surgical incisions. NPWT has been demonstrated to stimulate cell proliferation,
reduce inflammatory mediators, increase O2 partial pressure and reduce wound stress.
Surgical Incision Management Systems (SIMS) are battery-powered, single-patient
use systems designed to deliver 125 mmHg of negative pressure to closed incisions.
SIMS hold incision edges together, remove fluids as potential infectious sources and
act as a barrier to external contamination while delivering negative pressure. Multiple
studies have shown reduced rates of wound infection and complications when used
in Cardiothoracic, OB-Gyn, Orthopaedic and Vascular Surgery. SIMS have not
previously been evaluated for use in the non-elective trauma and acute care setting.
Method: Institutional Review Board approval was obtained for a single-center,
retrospective case-controlled study. Inclusion criteria: 18 years of age, non-elective
closed laparotomy incision performed by Trauma & Acute Care Surgery team.
Exclusion criteria: nearby ostomy, open wounds or other functional limitation
precluding use of SIMS dressing. Closure of skin was performed with sutures or
staples. SIMS remained in place for 4-9 days. Incisions were evaluated for infection,
dehiscence, hematoma or seroma immediately after removal and at post-operative
office visits. Additional data collected and analyzed included basic demographics,
BMI, smoking status, immunosuppression, diabetes mellitus, operation characteristics,
hospital readmissions and survival. Cases were matched with controls of equivalent
comorbidity conditions, wound class, procedure and surgeon.
Results: Forty-eight cases were identified along with matched controls. No statistically
significant difference in age, sex, height, BMI, surgical blood loss, wound class, hospital
length of stay or survival was found between groups. There were more patients with
diabetes in SIMS group. Significantly lower rate of wound infections (p = 0.04) and
hospital readmission (p = 0.05) were found in the SIMS group.
Conclusion: Results demonstrate a decreased rate of SSIs and hospital readmission
for any reason when using SIMS for management of non-elective closed laparotomy
incisions in trauma and acute care surgery. To our knowledge, the use of SIMS in
this setting has not previously been evaluated. Given these results, we recommend
considering increased use of SIMS to non-elective closed laparotomy incisions. Strength
of our findings is limited by the retrospective nature and limited sample size.

FASCIITIS

Keeley MD,Mohammad Karimzada BS, Mari Allison Ph.D., Angela Neville MD,
David Plurad MD, Brant Putnam MD, Christian deVirgilio MD Dennis Kim MD,
Torrance, CA
Background: Necrotizing soft tissue infections (NSTI) are rapidly progressive, and
diagnosis is based on a high index of suspicion, good clinical exam, and the Laboratory
Risk Indicator for Necrotizing Fasciitis Scoring System (LRINEC). Recent data has
questioned the validity of the LRINEC while studies have shown that major predictors
for NSTI are hyponatremia and leukocytosis. The purpose of this study was to validate
the LRINEC and create a modified LRINEC (mLRINEC) that would have better
accuracy.
Method: A retrospective analysis of patients referred to acute care surgery for
concern of NSTI over a five-year period at a single institution. LRINEC scores were
calculated from admission laboratories. The mLRINEC score excluded the c-reactive
protein (CRP) value. The mLRINEC was further adjusted with sodium corrected for
hyperglycemia (cNa) and leukopenia (2 pts given to WBC <4) to assess which was the
best test. An mLRINEC score≥4 was considered positive. An NSTI was defined by
pathologic reports.
Results: There were 482 patients referred for NSTI concern. Of these, 281 patients
were diagnosed with an NSTI and 201 were excluded from having an NSTI. Mean
age was 47 years old and 72.4% were male. Only 15.6% (n=75) had a CRP level on
admission, the LRINEC in this population had a sensitivity of 54.8% and a negative
predictive value (NPV) of 66.7%. When CRP was excluded on these patients
(n=75) the mLRINEC had a sensitivity of 77.4% and NPV 78.1%, (p=0.038). The
mLRINEC, when applied to the whole group (n=482), had a sensitivity of 64.8% and
a NPV 56%. Further adjusting mLRINEC for leukopenia had an increase in sensitivity
66.9% and NPV 57.3%, (p=0.06). When adjusting mLRINEC for cNa, or cNa and
leukopenia there was no increase in sensitivity (55.5% and 58.4% respectively). The
mLRINEC correlated with the number of debridements (p < 0.001) but did not
correlate with mortality (p= 0.644).
Conclusion: In our population, mLRINEC outperformed the traditional LRINEC.
When CRP is not included in the calculation (mLRINEC), there is a significant
improvement in the sensitivity. Correcting for cNa or leukopenia does not change the
predictive performance of the mLRINEC. The mLRINEC has a significant correlation
with the number of debridements, which indicates it may predict the severity of the
infection. Overall CRP is not helpful in predicting an NSTI when incorporated into an
LRINEC score.

Background: With increasing screening practices and awareness, the incidence of
gastro-duodenal ulcer (GDU) has decreased. Perforated GDU is thought to occur
rarely with advances in medical therapy. However; variability exists among institutions
with patients with perforated GDU. The aim of this study was to report a 10 year single
institutional experience in managing perforated GDU.
Method: We performed a 10 year retrospective analysis of patients presenting to our
institution with perforated GDU. Patient demographics, medication use, operative
intervention, hospital and 1 year post-discharge information was collected. Outcome
measures: hospital length of stay, in-hospital complications, and disease recurrence.
Results: Over 10 years, a total of 41 patients with perforated GDU were included with
mean age was 56.5±21.4 years, 70% male, and median American Anesthesiology Score
(ASA) 3[2-3]. 51% ulcers were pre-pyloric, 30% ulcers were duodenal, and remaining
was gastric. 51% patient had Helicobacter Pylori positive. 30% patient had history
of anti-inflammatory medication use. 14% patients had history of gastric ulcer and
treated. 83% had open primary repair with Graham patch while the rest (17%) had
laparoscopic repair. The mean intensive care unit stay was 2.5±1.2 and mean hospital
length of stay 6.1±3.5 days. The overall complication rate was 24% and mortality rate
was 7%. One year post-operative readmission rate, complication and recurrence rate
was 0%.
Conclusion: Perforated gastro-duodenal ulcer continues to persist despite increasing
screening and medical managements. H.pylori infection had high prevalence. Use of
anti-inflammatory medications had lower incidence among our patient population.
Further broadening of screening practices and spreading awareness of this disease
process is warrented.

QS 8. A FLIP OF A COIN: THE NATIONWIDE RISK OF MORTALITY AND
ADVERSE OUTCOMES FOR ABDOMINAL COMPARTMENT SYNDROME

Heniford MD, AB Christmas MD, RF Sing DO
Charlotte, NC
Background: Abdominal compartment syndrome (ACS) is a rare but often lethal
complication, therefore most of our treatment and understanding of ACS is guided
by small population single center studies. Our purpose was to define the incidence of
morbidity and mortality of this disease process and to identify risk factors for poor
outcomes using a comprehensive national database.
Method: The National Inpatient Sample (NIS) database was queried from 2006-2013
for all traumatic and non-traumatic diagnoses of ACS. Univariate analysis compared
outcomes by mortality and trauma status. The primary outcome was in-hospital
mortality, and secondary outcomes were hospital charges, length of stay (LOS), and
medical and procedural complications. A multivariate stepwise logistic regression was
then performed to identify independent predictors of mortality.
Results: 4,977 patients with ACS were identified, of whom 871 had traumatic and
4,106 had non-traumatic etiologies. Of these, 3,156 (63.2%) underwent an open
abdominal operation during their admission, and 2,302 (46.3%) underwent a
laparotomy. Average LOS was 20.9 ± 25.2 days, and the average hospital charges were
$297,643 ± 338,526 USD. 96.7% of patients developed medical complication, and
49.4% developed procedural related morbidity. Inpatient mortality was 50.2%.
Traumatic ACS patients were younger (46.3 ± 18.5 vs 59.1 ± 15.9 years), less likely to
be female (25.1 vs 41.6%) but more likely to be to have an open surgery (72.9 vs 61.4%)
including exploratory laparotomy (59.8 vs 43.4%), and require a tracheostomy (26.2
vs 15.9%); p<0.0001 for all. While the two groups had equivalent LOS, mortality and
procedural complications, traumatic ACS had lower rates of medical complications
(81.3 vs 100%) and higher charges ($331,474 vs $290,520); p<0.001.
Compared to survivors, ACS patients who died had equivalent rates of laparotomy,
gender, and traumatic or non-traumatic etiology. However, non-survivors tended
to be older, less likely to survive to tracheostomy, ventral hernia repair (VHR) or
gastrostomy, had lower LOS, fewer medical and procedural complications, and
decreased charges (p<0.05).
On multivariate analysis, increasing age (1.02 per year, 95%CI 1.05-1.12), Charlson
Comorbidity Index (1.08 per point, 1.05-1.18), and admission to a teaching hospital
(1.57,1.31-1.89) were independent predictors of mortality. Survival to reopen
laparotomy (0.70, 0.58-0.85), tracheostomy (0.35, 0.28-0.43), VHR (0.24, 0.15-0.38),
or the development of medical (0.42, 0.27-0.64) or procedural complications (0.73,
0.62-0.86) were predictors of survival; p<0.001 for all.
Conclusion: In this study of the NIS, over 50% of inpatients died from ACS and
almost all patients suffered associated morbidity (97%). Despite higher rates of
laparotomy, traumatic ACS has similar rates of survival and complications as nontraumatic ACS. Further investigation on treatment and early recognition of ACS is
warranted to reduce the risk of mortality to less than just the “flip of a coin.”

QS 9. POSTOPERATIVE MORTALITY FOR PATIENTS WITH COLONIC
VOLVULUS ADVERSELY AFFECTED BY ASSOCIATED COMORBIDITIES
H Dao MD, JW Kempenich MD, J Marcano MD, AJ Logue MD, KR Sirinek MD
PhD
San Antonio, TX
Background: While colonic volvulus is a less frequent cause of large bowel obstruction
in the United States, it still accounts for approximately 15% of such cases in general
surgery practice. Contemporary studies demonstrate a postoperative mortality around
14% for all patients undergoing surgery and as high as 24% for those undergoing
an emergent operation. Most deaths are thought to occur as a result of medical
comorbidities rather than from the surgical procedure itself. This study analyzes current
factors associated with mortality in patients undergoing surgery for colonic volvulus.
Method: The American College of Surgeons (ACS) National Surgical Quality
Improvement Program(NSQIP) database was queried for the year 2014. Patients
undergoing surgery for colonic volvulus were selected for analysis. Demographics,
comorbidities, surgical procedure performed, length of hospital stay, and 30-day
postoperative mortality were analyzed. Categorical variables were analyzed using ChiSquare and continuous variables were compared using T-test. A logistic regression
model was then created to assess the influence of independent variables for mortality.
Significance was established with a P value <.05.
Results: There were 1,077 patients who underwent an operation for colonic volvulus
during 2014 at NSQIP participating institutions. The mean age of these patients
was 63.7 years, 54.7% were female, 78.3% were white and 85.2% of operations were
classified as emergent. Mean length of hospital stay was 10.2 days. Overall mortality
was 3.9%. Univariate analysis revealed that mortality was higher among patients with
congestive heart failure (9.5% vs. 1.0%, P< .0001), acute renal failure (7.1% vs. 0.4%,
P< .0001), steroid use (11.9% vs. 2.6%, P <.001), hypertension (66.6% vs. 44.6%,
P<.005), and dyspnea (23.8% vs. 4.9%, P<.0001). Other variables associated with an
increased mortality rate were: an emergency operation (4.4% vs. 0.6%, P<.02) and
transfer from an outside institution (6.4% vs. 3.2%, P<.03). Multivariate analysis
showed that acute renal failure, dyspnea, and congestive heart failure were the only
variables associated with an increased postoperative mortality in patients with colonic
volvulus (Table 1).
Conclusion: The postoperative mortality rate for patients with colonic volvulus has
significantly decreased (3.9%) from previous reports and this is probably multifactorial.
Significant patient comorbidities (renal, pulmonary, cardiac) have been shown to play
a major role in the postoperative mortality of these patients with colonic volvulus. It
would appear that further reductions in the overall mortality for the surgical treatment
of patients with colonic volvulus depends upon early and aggressive perioperatory
medical management of the pathophysiology associated with these three organ systems.

QS 10. MANAGEMENT, OUTCOMES, AND COST OF NECROTIZING
SOFT TISSUE INFECTIONS AT A COMMUNITY TEACHING HOSPITAL:
SHOULD YOU SLASH BEFORE YOU DASH?
BT Grover DO, KJ Kallies MS
La Crosse, WI
Background: Necrotizing soft tissue infections (NSTIs) are rare, highly morbid, and
aggressive infections associated with substantial morbidity and mortality. Management
includes aggressive debridement, antibiotics, fluid resuscitation, reevaluation, and
nutritional support. Emergent operative debridement provides the best chance for
survival, as delays in operative treatment can be fatal. Given the complexity of
diagnosis and management of NSTI, the associated hospital charges are substantial.
The objective of this study is to review the management, outcomes, and cost among
patients treated for NSTI at our community teaching hospital. We also compared
patients who initially presented to outside facilities and transferred without operative
treatment to those who presented directly to our main campus.
Method: The medical records of all adult patients admitted to our community
teaching hospital with a diagnosis of NSTI from May 2006 through June 2016 were
retrospectively reviewed. Statistical analysis included t tests and Fisher’s Exact Test.
Results: Seventy four patients met inclusion criteria; 58% were male. Patient
comorbidities included diabetes (51%), chronic kidney disease (20%), peripheral
vascular disease (11%), and current or former tobacco abuse (58%). Upon admission,
65%, 17%, and 9% of patients presented with tachycardia, hypotension, and a fever,
respectively. Seven patients elected to receive palliative care and did not undergo
surgical treatment. The 30-day mortality rate was 22%. A total of 23 (31%) patients
were transferred from outside facilities, potentially increasing time between diagnosis
and operative treatment. Of all mortalities, 40% were from this group of patients.
There was a 188 % increase in patients presenting with NSTIs when comparing the
first 5 years to the last 5 years of the study period. Patients who died within 30 days
were older (mean age 68.5 vs. 54.0 years; P=0.001), and more likely to have peripheral
vascular disease (27% vs. 7%; P=0.048).
Conclusion: This study is one of the largest contemporary series, over a 10-year time
frame, from a U.S. community-based teaching hospital. NSTIs are becoming more
common, and have a high morbidity and mortality. They require extensive hospital,
staff, and financial resources. Early debridement is an essential aspect in treating this
disease. Referring hospitals with surgical capabilities should consider initial operative
debridement prior to transferring to the regional referral center.

QS 11. EMERGENT CHOLECYSTECTOMY IS SUPERIOR TO
PERCUTANEOUS CHOLECYSTOSTOMY TUBE PLACEMENT IN SEVERELY
ILL PATIENT WITH EMERGENT CALCULOUS CHOLECYSTITIS
BR Hall, PR Armijo, TR Burnett, D Oleynikov
Omaha, NE
Background: Percutaneous cholecystostomy (PC) tube placement has been well
studied in critically ill patients with acalculous cholecystitis, however the role of PC
remains undefined in patients who have multiple medical comorbidities who are
presenting with emergent calculous cholecystitis. The aim of this study is to compare
surgical outcomes in high-risk operative candidates between PC and laparoscopic or
open cholecystectomy.
Method: A query of the Vizient UHC database from October 2012 to October 2015
was done for high-risk patients with calculous cholecystitis, who underwent either PC,
laparoscopic cholecystectomy (LC), laparoscopic converted to open cholecystectomy
(CONV), or open cholecystectomy (OC) in the emergent setting. High-risk was
defined by a validated clinical algorithm that assesses 29 comorbidities, patient
demographics and major diagnosis. Major severity outcomes, mortality, length of stay,
and direct cost were compared between the groups. Statistical analysis was performed
using SPSS v23.0.0.0 using Chi-square tests with Bonferroni correction along with
non-parametric tests where appropriate, α=0.05.
Results: 13,521 patients with major illness severity score were analyzed (PC = 17.1%;
CONV = 8.2%; OC = 7.2%; LC = 67.5%). LC was the most common approach with
statistically significant lowest risk of death, complications, length of stay (LOS) and
cost (Table 1). Rate of conversion for laparoscopic cases was 10.8%. The risk of overall
complications was highest in OC (18.6%), and lowest in LC (4.9%) (Table 1). The
rate of overall complications in patients undergoing PC was nearly three fold higher
than LC (14% v 4.9%). PC had the highest death rate at 11.3% compared to 2.3% in
CONV and 0.8% in LC. Post-operative infection rates were similarly highest in the PC
group at 3% compared to the LC group at 0.7%. Aspiration pneumonia was highest
in the PC group at 3.3% compared to 0.9% in the LC group. LOS in PC was 10 days
compared to 6 days in LC. Similarly, cost in the LC group at $8,000 compared to PC
and CONV, both of which were estimated at $13,000.
Conclusion: Emergent cholecystectomy for calculus cholecystitis even in patients
with major severity of illness is safer and more cost effective than PC. While the
observed conversion rate and complication rate was higher then those reported in low
risk patients, PC had significantly worse outcomes compared to both LC and CONV
cases. While PC may be an option for patients with acalculous cholecystitis, our data
demonstrates significantly worse outcomes for patients undergoing PC compared to
both LC and CONV cases. Patients who are surgical candidates and present with
calculus cholecytitis should undergo cholecystectomy as the primary approach for their
disease.

QS 12. EFFECT OF A CLINICAL PHARMACIST ON THE TRAUMA
RESUSCITATION TEAM DURING RAPID SEQUENCE INTUBATIONS: A
PROSPECTIVE OBSERVATIONAL STUDY
CE Frank, C Dente MD, S Miller PharmD DABAT, BC Morse MD MS, P Rhee, MD
Atlanta, GA
Background: Clinical pharmacists are often a valuable luxury when on the trauma
resuscitation team and their value as a team member is often unrecognized. We
hypothesized that the use of a trauma pharmacist during resuscitation would reduce
the time to rapid sequence induction (RSI) for intubation and also administration of
maintenance sedation.
Method: A prospective observational cross-sectional study was employed to record
times from decision to intubate to administration of RSI medications as well as to
initiation of maintenance sedation at a Level I trauma center from April - July 2016.
Results: There were 39 patients observed that required RSI during resuscitation.
Due to limited resources, clinical pharmacists are not always present during trauma
activations, and their presence was observed only 62% of the time. When the clinical
pharmacist was present, time to induction was reduced by 50.49% (p<0.0001) and
time to administration of maintenance sedation was reduced by 55.78% (p=0.001).
A pharmacist arrived after intubation and/or maintenance sedation was withheld for
several patients, accounting for lack of congruency in all time windows. (Table 1)
Conclusion: Pharmacists can play a vital role in trauma resuscitations, and their
presence increases efficiency in obtaining definitive airway management and sedation.
Having a clinical pharmacist as a trauma team member allows nurses and physicians
to concentrate on the initial care of the patient and should decrease time to necessary
advanced diagnostics and interventions, which may improve outcomes.

QS 13. GERIATRIC TRAUMA PATIENTS WITH RIB FRACTURES: IS
THERE A DIFFERENCE IN OUTCOMES BETWEEN PATIENTS TREATED
WITH RIB FIXATION COMPARED TO NON-OPERATIVE MANAGEMENT?
FR Ali-Osman MD, AJ Mangram MD, GR Shirah MD, JS Sucher MD, AK
Hollingworth MD, VA Johnson MD, P Moeser MD , JK Dzandu PHD
Phoenix, AZ
Background: We are seeing an increase in the number of our geriatric trauma patients
age≥60 years (G-60). Traditionally, rib fractures have been managed non-operatively in
the majority of cases with flail chest being the most cited exception. In the last decade,
the enthusiasm to repair rib fractures has grown, however outcomes in G-60 patients
treated with operative fixation (ORF) remains largely unknown. The purpose of this
study was to compare outcomes in G-60 patients treated with (ORF) vs. non-operative
management (NOM).
Method: We performed a retrospective review at our level I trauma center. We queried
our registry and identified G-60 patients who had rib fractures treated with ORF or
NOM. Age, gender, mechanism of injury (MOI), BMI, # of ribs broken or fixed, ISS,
hospital/ICU length of stay, ventilator days, discharge disposition and mortality were
examined. We also assessed the effect of ORF on pulmonary function tests (PFT’s).
T-test, Mann-Whitney U and Chi-Square test and ANOVA were used for analysis.
Results: From May 2014 through October 2016, 64 patients underwent ORF,
compared to 135 patients treated with NOM from May 2013 through April 2014. The
median age (ORF vs. NOM) was 68.5 vs. 72, p= 0.004. There was no difference in
gender, p=0.183 or BMI, p=0.777. The MOI was associated with treatment category
(ORF vs. NOM), p=0.001. The median # of ribs broken (ORF vs. NOM) was 7 vs. 5,
p=0.001. The number fixed was 3. The median ISS (ORF vs. NOM) was 17.5 vs. 14.0,
p =0.027. The median vent days were similar p=0.935. The median ICU-LOS (ORF
vs. NOM) was 6 (IQR=3-10) vs. 2 (IQR= 0-5), p=0.001. The median HLOS (ORF vs.
NOM) was 12 days (IQR= 9-16_vs. 4.8 (IQR=2.9-8.4), p= 0.001. There was 1 out of
64 deaths (1.5%) in the ORF group compared to 13 out of 135 (9.6%) in the NOM;
p=0.04. Discharge destinations were similar (p=0.145). Repeated measures ANOVA
indicated there was a statistically significant effect of ORF on PFT’s (FEV1 and FVC)
post-op.
Conclusion: Our study shows that patient outcomes are different when treated
with ORF vs. NOM. In particular, there was a significant decrease in mortality.
Interestingly, there was a statistically significant increase in PFTs with ORF.
Randomized controlled studies are needed to consolidate these results, including
examination of the effect of ORF on patient satisfaction, pain control and return to
pre-injury daily activities.

QS 14. ABDOMINAL SEATBELT SIGN: NO LONGER A REQUIREMENT FOR
ADMISSION?
TR Kopelman MD, JW Walters DO, JN Bogert MD, PG Pieri MD, KM Davis, MD,
SJ Vail MD
Phoenix, AZ
Background: The Eastern Association for the Surgery of Trauma guideline regarding
blunt abdominal trauma (BAT) states that any patient with a seatbelt sign (SBS) should
be admitted for observation and serial physical examination despite radiographic
evaluation. Given the improvements in computed tomographic imaging (CT) since this
guideline appeared in 2002, the purpose of this study was to determine if admission
remains necessary after negative CT in patients with suspected BAT and documented
SBS.
Method: After obtaining IRB approval, a retrospective evaluation of adult trauma
patients (age > 15 years) who presented over a 5 1/2 year time period to a Level I
trauma center status post motor vehicle collision were reviewed. Inclusion criteria
included the presence of a documented SBS and performance of CT of the abdomen/
pelvis. Abnormal CT findings were defined as any intra-abdominal abnormality (IAA)
possibly related to trauma as interpreted by the attending radiologist. A CT SBS was
defined as any soft tissue changes seen on CT in the area of the SBS. Outcomes were
measured at 24 hours and/or time of discharge and included clinical deterioration,
need for celiotomy, and mortality. Negative predictive value of CT was defined by the
subsequent need for intervention or the delayed identification of an IAA.
Results: One hundred and seventy five patients met inclusion criteria. CT evidence of
soft tissue changes consistent with a CT SBS was observed in 55 patients (31%). While
more likely to be radiographically evident if the SBS was described on examination
as an ecchymosis (39/94;42%) rather than an abrasion (16/81;25%), ultimately the
presence of a CT SBS had no effect on incidence of underlying IAA. Overall, 24
patients (15%) had CT imaging concerning for IAA: 6 had radiographic evidence
of an isolated solid organ injury (SOI), 14 had findings suspicious for hollow viscus
injury (HVI), 3 had findings concerning for both SOI and HVI and 1 had a placental
abnormality. Four patients underwent immediate celiotomy based upon CT findings
concerning for HVI and one patient had a delayed celiotomy for CT evidence of a
mesenteric hematoma and Grade II liver laceration with worsening clinical exam.
On laparotomy, all patients had injuries confirming CT findings. An additional 2
patients had significant CT findings isolated to CT SBS, one with significant muscular
transection and one with active bleeding. The remaining 149 patients (85%) had CT
interpretation negative for traumatic IAA. No patient with negative imaging required
delayed intervention or had delayed identification of IAA. Overall, despite the presence
of a SBS, CT in a patient with suspected BAT had a negative predictive value of 100%.
Conclusion: This study suggests that hospital admission and prolonged observation
does not benefit patients with suspected BAT and documented SBS after negative CT.

QS 15. NOVEL CLINICAL COAGULOPATHY SCORE IS HIGHLY
SENSITIVE FOR MORTALITY RISK SECONDARY TO TRAUMA-INDUCED
COAGULOPATHY RELATED HEMORRHAGE
PM Einersen MD, HB Moore MD, A Sauaia MD PhD, A Banerjee PhD, CC Silliman
MD PhD, EE Moore MD
Aurora, CO
Background: Trauma-induced coagulopathy (TIC) is the most common preventable
cause of post-injury mortality, accounting for up to 50% of deaths in hospitalized
patients. In the ongoing effort to improve understanding and management of TIC,
the Trans-Agency Consortium for Trauma-induced Coagulopathy (TACTIC) has
established a quantitative clinical coagulopathy score (CCS), which our group has
previously demonstrated to provide early discrimination of injury severity, transfusion
need and mortality. In this follow-up study with increased statistical power, we set out
to evaluate associations between TACTIC CCS and cause of death.
Method: Data were reviewed for 342 patients admitted in three prospective studies
at a level 1 trauma center between April, 2014 and January, 2016, with inclusion
criteria specifying highest level trauma and TACTIC CCS issued by attending
surgeon at initial ED assessment as follows: 1) Normal Hemostasis (negative), 2) Mild
Coagulopathy (equivocal) 3) Coagulopathy Refractory to Direct Pressure (possible
positive), 4) Coagulopathy Requiring Blood Component Transfusion (positive) and 5)
Diffuse Persistent Bleeding from Multiple Sites (definitive positive) (Figure 1). Cause
of death was assigned by a panel of 2 physicians following retrospective chart review.
Statistical variance between score groups was assessed using one-way ANOVA and
Spearman’s correlation.
Results: Of 342 patients reviewed, 278 (81.3%) were male, 273 (79.8%) were white
and 185 (54.1%) sustained blunt injuries. Postive TACTIC CCS (i.e. score > 3) was
associated with overall mortality of 48.8%, odds ratio 10.1 (p<0.0001) and mortality
in the first 24 hours of 31.1%, odds ratio 12.5 (p<0.0001). The leading cause of overall
and early mortality in patients with positive TACTIC CCS at ED presentation was
uncontrolled hemorrhage secondary to TIC (35.0% and 46.7% respectively) and all
seven patients with mortality attributable to TIC-related hemorrhage received positive
initial TACTIC CCS representing 100% sensitivity in this cohort.
Conclusion: Clinical assessment of trauma patients using TACTIC CCS
at presentation offers a useful adjunct to conventional clotting assays and
thromboelastography (TEG). Positive TACTIC CCS provides a highly sensitive
indication of which patients are at greatest risk for hemorrhagic death secondary to
TIC allowing for crucial therapy to be initiated promptly at the point of care while lab
tests are in process or in settings where they may not be available to the provider.

Background: Geriatric patients (≥ 60 years) are exceptionally vulnerable to single or
multiple episodes of fall mediated orthopedic injury. Vitamin D deficiency has been
associated with poor clinical outcomes in patients with orthopedic injury. Here we
present a study assessing the impact of Vitamin D deficiency in the clinical outcomes of
the geriatric trauma patient.
Method: A retrospective chart review of all traumatic geriatric orthopedic injury
patients from 2006 to 2016 was conducted. Patients were grouped based on initial
Vitamin-D level of (A) ≤ 13 ng/mL (VD-) or (B) > 13 ng/mL (Control). General
demographics, fracture characteristics and clinical outcomes were evaluated. A chisquare or Fisher’s exact test was employed for statistical significance in large or small
sample sizes, respectively. A p ≤ 0.05 is considered statistically significant.
Results: Out of 696 geriatric trauma patients, 28% (n = 193) were VD- (13 ± 0.7
ng/mL) vs. 72% (n = 503) were Control (26 ± 12 ng/mL). Our VD- trauma cohort
consisted of 67% female, 77 ± 11 y/o and 9 ± 5 ISS. Fall (55%) was the most common
cause of injury. Hypertension (24%) followed by diabetes (9%) and congestive heart
failure (3%) were the dominant comorbidities. Our analysis showed statistically
significant differences in fracture profiles (femoral neck displacement) and clinical
outcomes (time to ambulation and hospital length of stay). VD- patients were found
to have significantly more femoral neck fracture (53% VD- vs. 41% control; p<0.001),
longer time to ambulation (3.8 ± 2 days VD- vs. 3.5 ± 2 days control; p=0.006) and
hospital length of stay (6.4 ± 3 days VD- vs. 6 ± 5 days control; p=0.04).
Conclusion: Our analysis reveals significant differences in the fracture profile
and clinical outcomes of Vitamin D deficient geriatric trauma patients. Given the
vulnerability of this population to fall associated orthopedic injury, muscle weakness
and mortality, the effect of Vitamin D supplementation should be evaluated to
determine its effect on outcomes.

QS 17. INCIDENCE AND PREDICTORS OF EMERGENCY DEPARTMENT
THORACOTOMY PERFORMED OUTSIDE OF TEMPORAL GUIDELINES
FOR TRAUMA ARREST

MD, CJ Fox MD, R Lawless MD, K McVaney MD, M Migliero RN, M Cohen MD,
EE Moore MD
Denver, CO
Background: Emergency department thoracotomy (EDT) is a potentially lifesaving procedure, the success of which is dependent upon accurately identifying
salvageable patients. Based upon the Western Trauma Association data, our trauma
center has a guideline predicated upon the duration of pre-hospital cardiopulmonary
resuscitation (CPR). The primary objective of this study was to examine adherence to
the institutional guideline, as well as factors leading to deviation. A secondary objective
was to compare survival following EDT performed within and out of guidelines.
Method: Patients who underwent EDT following trauma arrest at our level I trauma
center from 2011-2015 were reviewed. Time of CPR initiation was obtained from the
paramedic trip sheet, and time of EDT from nursing records. An EDT was considered
to be “within window” based on the following defined institutional criteria: < 15
minutes of pre-hospital CPR for penetrating torso trauma; < 10 minutes for blunt
trauma; < 5 minutes for penetrating extremity trauma. Patients with isolated head
trauma, as well as those who underwent EDT for refractory hypotension (without
arrest) were excluded. Patients were stratified by mechanism of injury, age, and gender.
Results: A total of 243 trauma arrest patients were analyzed; 146 (60.1%) underwent
EDT. Overall, 65 EDTs (44.5%) occurred out of window. Deviation from the
guidelines occurred more commonly in cases of penetrating extremity trauma (80.0%)
and age < 18 years (57.1%), and less commonly in cases of penetrating torso trauma
(41.3%) and age > 65 years (40.0%) (Table). Likelihood of deviation was not associated
with mechanism of injury, age or gender. Overall, 15 (10.3%) EDT patients survived
to hospital discharge; 6/75 (8.0%) for penetrating torso trauma, 7/66 (10.6%) for
blunt trauma, and 2/5 (40.0%) for penetrating extremity trauma (p=0.07). Survival
was 14/81 (17.3%) in the within window group and 1/65 (1.5%) for the out of window
group (p<0.01). The singular patient who survived following out of window EDT
sustained a brachial artery transection, underwent EDT after 6 minutes of pre-hospital
CPR, and was discharged home neurologically intact.
Conclusion: Almost one half of EDTs occurred outside of institutional temporal
guidelines, and were nearly universally unsuccessful. Efforts to mitigate this finding
should target pediatric and penetrating extremity trauma patients. The survival
observed herein following EDT performed within the temporal pre-hospital CPR
window represents the highest reported to date.

QS 18. SHOULD INFANTS WITH BLUNT TRAUMATIC BRAIN INJURIES
AND INTRACRANIAL HEMORRHAGE HAVE ROUTINE REPEAT
IMAGING?
EP Hill MD, B Bitter MS4, J Reyes MEd, R Grundmeyer MD, SD Helmer PhD, JM
Haan MD
Wichita, KS
Background: Children with suspected brain injury usually undergo head CT, and if an
injury is identified, follow-up CT is routine within 24 hours. To date, no studies have
evaluated the practice of repeat imaging nor the diagnostic or therapeutic value of these
repeat CTs in infants as a distinct population. The purpose of this study was to: (1)
evaluate progression of traumatic brain injuries, (2) determine the prevalence of repeat
imaging and whether or not it changes patient management, and (3) to determine if
detecting worsening intracranial hemorrhage correlates with other clinical findings
such as seizure, changes in neurologic exam, or retinal hemorrhage.
Method: A 7-year retrospective review was conducted of all trauma patients aged ≤ 12
months with blunt traumatic head injury (N=50). Data included demographics, head
injury details, number of repeat scans and findings, change in GCS or neurological
exam, management changes following CT scans, and hospital outcomes.
Results: Most patients (68%) had at least one repeat CT, with nearly three-quarters
(74%) showing no change or a reduction in hemorrhage. Presence of neurological
symptoms (p=0.025) and decrease in GCS (p=0.043) were significantly associated
with having repeat CT scans. There was a correlation between increased hemorrhage
on CT in those patients with subarrachnoid hemorrhages (p=0.012) and decreased
GCS (0.019), but not with retinal hemorrhage or seizure activity. Repeat imaging led
to changes in management (staying in the ICU, additional repeat imaging, addition
of hypertonic saline, or going to the operating room) in 8 patients; in 4 patients this
change in management was a surgical procedure. Repeat CT scans were associated with
increased length of stay in the hospital (p<0.045), but not with increased ventilator
days, ICU length of stay, or mortality.
Conclusion: Findings from this study confirm a correlation between change in
neurological exam, namely decreased responsiveness, and increasing size of intracranial
hemorrhage in infants. However, size of initial hemorrhage, seizure, and retinal
hemorrhage were not predictive of increased hemorrhage. These findings and the
difficult nature of neurologic exams support the practice of routine repeat head CT in
infants with blunt traumatic brain injuries. Larger and prospective studies may show
that some populations are less likely to progress and may not require routine repeat
imaging as has been seen in older children and adult populations.

QS 19. DAMAGE CONTROL LAPAROTOMY IS ASSOCIATED WITH
INCREASED ABDOMINAL COMPLICATIONS: A MATCHED ANALYSIS
M J George MD, SD Adams MD, MK McNutt, JD Love DO, LJ Moore MD, CE
Wade PhD, JB Holcomb MD, JA Harvin MD
Houston, TX
Background: Damage control laparotomy (DCL) is thought to be associated with
increased abdominal complications compared to definitive laparotomy (DEF). Proving
the difference between these two interventions is difficult retrospectively and cannot be
controlled for using multivariate modelling. The purpose of this study is determine the
effect of DCL on abdominal complications by comparing two groups: DCL patients
who were prospectively adjudicated to have been patients who could have safely been
closed at the primary laparotomy and those who underwent DEF.
Method: Patients from 2011-2015 who underwent emergent laparotomy for trauma
were included. From 11/1/2013 - 10/31/2015 at a major university trauma center, we
performed a quality improvement project in which we prospectively and collaboratively
adjudicated every DCL. The adjudication process occurred by majority vote after each
emergency laparotomy. This group of adjudicated DCL patients was then matched
to patients who underwent DEF in a 1:1 ratio according to mechanism of injury,
abdominal injury severity, operating room transfusions, and performance of a colon
resection.
Results: From 2011 - 2015, 1,029 trauma patients underwent emergency laparotomy
- 665 (65%) underwent DEF, 321 (31%) underwent DCL, and 43 (4%) died
intraoperatively. 27 of 101 DCLs during the quality improvement period were
adjudicated to have been patients who could have safely undergone DEF. Matching
resulted in 16 pairs of patients who underwent DCL and DEF and were similar
in terms of demographics, vital signs, injury severity, transfusions and procedures
performed in the operating room. Patients undergoing DCL were more likely to have
a fascial dehiscence (38% versus 0%, p=0.018), organ/space surgical site infection
(56% versus 19%, p=0.066) and to be re-opened after fascial closure (38% versus 0%,
p=0.018).
Conclusion: In a group of matched patients, including patients who underwent DCL
but could have safely undergone DEF, DCL was associated with increased abdominal
complications. We believe that this study accounts for residual confounding not
controlled for in other studies of DCL. Thus, this represents the least-biased treatment
effect of DCL reported to date.

QS 20. ROUTINE “PAN-SCAN” IS NOT INDICATED IN THE ELDERLY
AFTER GROUND LEVEL FALLS
C Kim BS, R Sartin BS, S Dissanaike MD
Lubbock, TX
Background: Ground level falls are a common injury mechanism in elderly patients.
We have noticed a trend in recent years toward performing a “pan scan” (computed
tomography (CT) of head, C-spine, chest abdomen and pelvis) at initial ER evaluation
of these patients, similar to what has become commonplace in motor vehicle collisions
and other high impact trauma. While a head CT may be justified in this population
due to age-related cerebral atrophy, dementia hindering an accurate neurologic
examination, concomitant anticoagulation or other indications, we hypothesized
there was little benefit from the remaining CT scans. Our hypothesis was that a
panscan was not indicated in elderly patients with ground level falls, GCS of 15 and
hemodynamically stable.
Method: Retrospective review of patients who presented to a level 1 trauma center after
a ground level fall January 2013 -May 2015. Inclusion criteria were hemodynamically
stable patients > 55years of age with a GCS of 15, who received a panscan during initial
ER evaluation. Radiologist reads of the scans were reviewed for new findings on CT;
clinical documentation was then reviewed for evidence of a change in management
based on CT findings.
Results: 153 (21%) patients received panscans, resulting in an additional 134 (87.6%)
new findings.
The most common findings were cervical spine injuries 15 (9.8%), hematomas 13
(8.5%), rib fractures 13 (8.5%). 45 (6%) resulted in a minor change in management,
such as use of a neck brace (8, 5.2%), serial examination (7, 4.6%), pain control (5,
3.3%), ICU observation (4, 2.6%), oxygen therapy (3, 2.0%), occupational therapy/
physical therapy (1, 0.7%), pulmonary toilet (1, 0.7%), non-operational sacral fracture
treatment (1, 0.7%) and other alterations (3, 2.0%).
One patient received tube thoracostomy for findings of pneumothorax on chest CT,
and 2 patients (1.3%) underwent surgery for findings of dens and odontoid fractures
on cervical spine CT. All three had clinical symptoms and signs suggestive of their
diagnosis, which would have led to directed evaluation regardless of the panscan.
Conclusion: The major benefit of additional CT scans in imaging patients with ground
level falls was to diagnose occult cervical spine injuries or pneumothorax; however
these findings occurred in fewer than 5% of patients. In patients with stable vital
signs amenable to physical examination, there is no indication for routine panscan;
use of CT of the cervical spine , chest, abdomen or levis should be based on clinical
evaluation. Reducing the use of panscans will avoid unnecessary radiation and contrast
exposure to patients while limiting waste of healthcare resources.

QS 21. ACUTE KIDNEY INJURY IN TRAUMA PATIENTS RECEIVING
CHLORIDE-RICH VS. CHLORIDE RESTRICTIVE RESUSCITATION
EJ Glendinning MD, SD Barker MS4, J Reyes MEd, SD Helmer PhD, RJ Nold MD,
JM Haan MD
Wichita, KS
Background: Recent studies have shown a positive association between fluid
resuscitation with chloride-rich fluids (such as normal saline) and acute kidney injury
in several patient populations. Among surgery patients, use of chloride-restricted
fluids has been associated with decreased fluid requirement, transfusions, decreased
length of stay and ventilator days, and decreased need for dialysis. Within the trauma
population, chloride-restrictive resuscitation has been shown to be associated with
less severe biochemical abnormalities compared to patients who received chloride-rich
fluids. Our goal in this study was to compare clinically significant outcomes in trauma
patients receiving chloride-rich vs. chloride-restrictive fluid resuscitation.
Method: A retrospective chart review was conducted of all adult trauma patients who
presented to our Level 1 trauma center with an injury severity score > 15, and who
did not have a pre-existing diagnosis of Stage IV chronic kidney disease, from March
2011 through April 2015. In March 2013 the multidisciplinary trauma team changed
the standard resuscitation fluid available in the trauma bay to chloride-restricted
resuscitative fluid (Period II) as the standard for resuscitation in light of evidence in
favor of its use. The standard IV fluid available prior to that time was normal saline
solution, which has a supraphysiologic chloride concentration of 154 mEq/L (Period I).
Data collected included the type and volume of IV fluid received as well as urine output
and creatinine through hospital day 7. We also collected data regarding nephrology
consultation and in-hospital dialysis. Acute kidney injury was identified based on urine
output values averaged over each day and by increased creatinine values according to
standard definitions.
Results: Data were collected on 528 patients during the study periods. Of those
patients, 274 were treated during Period I and 254 during Period II. These groups were
similar with regards to initial vital signs, initial creatinine, and injury severity. Analysis
of rates of acute kidney injury did not show a significant difference between these
groups. Analysis of clinical outcomes showed no difference between ICU admissions,
ICU days, or mechanical ventilation. There was a nonsignificant trend toward fewer
ventilator days (3.5 days vs. 4 days, P =0.18) and decreased hospital length of stay (6
days vs. 7 days, P =0.10) in those treated during Period II.
Conclusion: Among trauma patients presenting with ISS >15, our data do not
demonstrate significant differences in rates of acute kidney injury or major outcome
measures between groups who initially receive chloride-rich versus chloride-restrictive
IV fluids. Nonsignificant trends were seen toward decreased length of stay and
ventilator days among chloride-restricted patients. Further study may be indicated as to
how the benefits of chloride-restrictive resuscitation extend to the trauma population.

QS 22. BASE DEFICIT IS SUPERIOR TO LACTATE IN TRAUMA
JW Davis MD, RC Dirks PhD, Am Kwok MD, LP Sue MD, P Tran MD, MM Wolfe
MD
Fresno, CA
Background: Base Deficit (BD) and lactate have been used as biochemical indicators
of shock and effectiveness of resuscitation. An animal study demonstrated strong
correlation between lactate and BD, but there has been limited data comparing BD and
lactate on admission in trauma patients. The purpose of this study was to determine the
association of BD and lactate and to determine if one is superior.
Method: A retrospective review of all trauma patients admitted to an ACS verified
level I trauma center from 3/2014 through 2/2016 was performed. An arterial blood
gas and serum lactate were part of the admission trauma lab panel for the highest
level of activation. Data collected included demographics, systolic blood pressure on
arrival, ISS, BD, lactate, blood transfusion, volume of resuscitation and outcomes.
Patients were excluded for absent BD or lactate data or if the ABG and venous blood
draw were more than 10 minutes apart. BD was modeled as a continuous variable and
categorically; normal (2 to -2), mild (-3 to -5), moderate (-6 to -9) and severe (< -10).
Lactate was modeled as a continuous variable. Statistical analysis was performed with
Mann Whitney U test, X2 and regression analysis with significance attributed to p <
0.05. Data are expressed as mean + SD.
Results: 752 patients were included in analysis. BD and lactate had a strong correlation
(r = -0.78 p < 0.001). As continuous variables, higher lactate and more negative BD
were associated with administration of blood products within 24h and mortality. On
multivariate regression, only BD was associated with administration of blood products
and mortality (OR = 0.8, p < 0.001; OR = 0.9, p = 0.004, respectively). As a categorical
variable, worsening BD was associated with decreased BP, higher ISS, increased
transfusion need, and worse outcomes.
Conclusion: BD and lactate are strongly related. BD was superior to lactate in assessing
risk of mortality and the need for blood. The BD categories may discriminate high risk
trauma patients better than lactate.

QS 23. MINIMALLY INVASIVE VERSUS OPEN CYTOREDUCTIVE
SURGERY AND HYPERTHERMIC INTRAPERITONEAL CHEMOTHERAPY
- A COMPARISON OF SHORT TERM OUTCOMES
RW Day MD, A Ashfaq MBBS, R Gray MD, B Pockaj MD, CC Stucky MD, N Wasif
MD
Phoenix, AZ
Background: Cytoreductive surgery and HIPEC is being increasingly used as a
treatment option for pseudomyxoma peritonei and peritoneal carcinomatosis. The
traditional open approach has been well described in the literature, but is associated
with considerable morbidity and mortality. In this study we describe our experience
with minimally invasive HIPEC and compare short term outcomes with conventional
open HIPEC.
Method: A retrospective review of all 80 patients undergoing HIPEC at a single
institution between 2010 and 2016 was performed. Demographic data and outcomes
data were stratified by surgical approach and analyzed based on intention to treat.
Results: Fifty-five patients undergoing open HIPEC were compared with 25 patients
undergoing minimally invasive HIPEC. The two groups had similar demographics,
except the minimally invasive group was more likely to have an ECOG performance
status of 0 (p=0.016). Two patients undergoing minimally invasive approach were
converted to an open procedure (8%) and 3 patients (12%) underwent palliative
HIPEC. The median surgical peritoneal cancer index (PCI) score was higher for the
group undergoing open surgery (14 vs. 3, p=<0.001). There was no difference in ability
to achieve a CC-0 or CC-1 resection between groups (72.7% vs. 88%, p=0.158). The
median length of stay was significantly shorter for the minimally invasive HIPEC
group (3 vs. 9 days, p=<0.001), with two patients successfully undergoing outpatient
HIPEC. Patients undergoing minimally invasive HIPEC had both lower morbidity
overall (76.3% vs. 28%), p=<0.001) and lower major morbidity (40% vs. 4%, p=0.001)
when compared to open HIPEC. There was no difference in 90-day mortality.
Conclusion: Conclusion: Minimally invasive HIPEC is a safe approach for patients
with primary or secondary peritoneal malignancy, with less morbidity and shorter
length of stay compared to open HIPEC. Patient selection is important, and patients
with low PCI scores or undergoing palliative HIPEC deserve consideration of
minimally invasive approaches.

QS 24. REDUCING VTE EVENT RATES IN COMPLEX ABDOMINAL
CANCER SURGERY: A RETROSPECTIVE, SINGLE INSTITUTE
COMPARISON OF DEXTRAN VS HEPARIN
Richard Sleightholm, John Burt, Lynette Smith, Duncan Watley, Steven Wahlmeier,
Asish Patel, and Jason Foster
Omaha, NE
Background: VTE rates in cytoreductive surgery (CRS) for peritoneal metastasis
(PM) without prophylaxis are high, 30-50%. Many factors in this population promote
VTE events including tumor burden, tumor hypercoagulability, performance status,
procedure duration, inflammation, and immobility. In CRS the major deterrent to
heparin based prophylaxis is the significant bleeding risks inherent in these procedures
which often require multi-visceral resections. When heparin prophylaxis is employed
it is often postoperative, and rates still remain as high as 20%. As an alternative
to heparin, Dextran has been used in PM patients at our institution both pre and
postoperatively. Herein we compare VTE events for heparin & dextran in 117 PM
patients who underwent CRS.
Method: A retrospective analysis (2010-15) identified 69 and 48 patients who
underwent CRS and received dextran-40 or heparin, respectively. Dextran was
started (25 ml/hr) in the OR prior to incision and maintained for at least 72 hours
postoperatively. Similarly, unfractionated heparin 5000U was administered prior to
incision and continued post-operatively throughout the entire hospital stay. SCDs were
used in all patients, and physical therapy ambulated patients daily. The incidences of
perioperative bleeding and VTE rates in-hospital, 30 days, 90 days were determined.
Results: Both dextran and heparin therapies were tolerated without any adverse
events. Median lengths of stay for patients receiving dextran or heparin were 10 and
9 days respectively. No differences were observed in the demographics of the patients
studied, and median age was 58 in both groups. Surgical outcomes were comparable
between cohorts. The heparin group experienced slightly higher rates of kidney
complications (p = 0.02), but not other differences were found between medical and
surgical complications. In-patient, 30-day, and 90- day VTE rates were found to be 5.8
v 10.2%, 8.7 v 10.2%, and 8.7 v 12.5% for dextran v heparin respectively (P = 0.7, 1.0,
and 0.5 respectively). No pulmonary emboli were observed in the dextran group, while
2 patients were identified in the heparin group. Overall VTE event rates were 8.7 and
12.5% (p=0.55).
Conclusion: Demographics, surgical procedures, and complication rates were
comparable between patients receiving dextran and heparin. Although VTE rates were
lower in those administered dextran, this was not statistically significant. Based on
these findings, dextran appears to be a safe and effective alternative to heparin based
prophylaxis in those undergoing advanced abdominal surgeries. A non-inferiority
clinical trial is warranted and necessary to validate the safety/utility of dextran based
VTE prophylaxis compared to UFH or LMWH.

QS 25. FIT TEST FOR COLORECTAL CANCER SCREENING: OUR
COMMUNITY EXPERIENCE
EJ Furay MD, J Uecker MD, JM Kerr MD
Austin, TX
Background: The gold standard for screening for colorectal carcinoma (CRC) is
colonoscopy. There are other approved methods for CRC screening from the USPSTF
including stool based studies. Fecal immunochemical tests, which utilize antibodies
against human hemoglobin to detect the presence of blood in stool have been gaining
popularity. We set out to see if in an urban population if these were effective screening
tools.
Method: From 2012-2015 packets, which including qualitative Fecal
Immunohistochemical Tests (FIT) and a letter explaining the purpose of the packet,
were mailed to patients 50-75 years old who had been seen within the Seton Healthcare
Family Clinic. Patients then mailed in these kits back and if positive were referred
for colonoscopy. Patient that had a colonoscopy within a year of having a positive or
negative FIT test were included. Information about patient follow up colonoscopies was
determined by chart review or by requesting records from physician who performed
the colonoscopy. We then determined whether the colonoscopy was normal, had
premalignant lesions or cancerous lesions based on biopsy results. Normal included
polyps with no malignant potential. One patient was excluded due to inability to
obtain pathology records regarding polyp biopsied.
Results: During these 4 years, 3505 kits were mailed out and 596 were returned
making the response rate for this mode of distribution 17% overall. Of the 596 FIT
tests that were returned 36 were positive and 560 were negative. Upon chart review
we were able to obtain information on 32 follow up colonoscopies. Nineteen of these
patients had positive FIT tests and 13 had negative FIT tests. Of the patients with
positive FIT tests and a colonoscopy 12 were found to have precancerous lesions
(63.16%). Of the patient with negative FIT tests and a colonoscopy 3 were found to
have precancerous lesions (23.07%). Calculating specificity and sensitivity based on our
results the FIT test had a specificity of 58.82% and a sensitivity of 80%. No cancerous
lesions were found.
Conclusion: It was hypothesized that compliance rates would be higher with a simple,
less invasive test that could be performed easily at home. In our population, which
includes many underserved and underfunded patients we found that the compliance
rate was poor. A 17% response rate does not appear to be a promising and effective
screening method for this population. FIT test in our community was not as effective
screening tool as previously reported in literature.

QS 26. SPLENECTOMY IN HEMATOLOGIC DISEASE: DO WE MAKE A
DIFFERENCE?
Sheaffer WW, Mikhael JR, Neville MR, Harold KH, Gray RJ, Wasif N, Pockaj BA,
Stucky CCH
Phoenix, AZ
Background: Splenectomy is an accepted treatment for idiopathic thrombocytopenic
purpura (ITP); however, its role in the management of other hematologic disorders is
not well-established. We evaluated our recent splenectomy outcomes to identify benefits
for patients undergoing splenectomy for diagnostic and therapeutic purposes.
Method: We performed a retrospective review of patients undergoing splenectomy with
an unknown diagnosis (UD), a hematologic malignancy (HM) or ITP from 2006 to
2016. Surgical indications and postoperative, hematologic, and diagnostic outcomes
were evaluated.
Results: Of the 113 patients undergoing splenectomy, 31% had UD, 29% had HM,
and 40% had ITP. Comorbidity index, body mass index, splenic weight and length,
and preoperative blood counts differed amongst the groups (Table 1). The majority
(74%) of patients underwent laparoscopic splenectomy with HD patients having the
highest rate of open splenectomy (36%). Post-operative complications and outcomes
were similar amongst the groups in terms of transfusions, infections, and readmissions
(Table 1).
Indications for splenectomy in UD were cytopenias (20%), B-symptoms (3%),
splenomegaly symptoms (9%) and a combination of these indications (60%).
Definitive diagnosis was achieved in 46% of patients. Of these patients, 69% had
cytopenias, 50% B-symptoms, 50% splenomegaly, 25% splenic mass, 63% prior
bone marrow biopsy. Improvement in indications were seen in 57% of patients (50%
cytopenias, 25% multiple factors, 15% splenomegaly and splenic mass symptoms, 5%
B-symptoms). Indications for splenectomy in HM were cytopenias (33%), B-symptoms
(3%), splenomegaly symptoms (12%), and a combination of these 52%. The diagnosis
changed after splenectomy in four (12%) of the HM patients. Improvement in
symptoms or labs occurred in 52% (65% multiple factors, 9% cytopenias, and 9%
splenomegaly symptoms).
Conclusion: Splenectomy was able to provide a diagnosis in almost 50% of
undiagnosed patients with low morbidity. In addition, 50% of HM patients had
improvement of labs and symptoms. These groups compare favorably to our ITP
patients and therefore splenectomy may be a useful diagnostic and therapeutic tool in
UD and HM patients for the correct clinical situation.

QS 27. INFLAMMATORY BREAST CANCER REMAINS A POOR
PROGNOSIS: A SINGLE INSTITUTION REVIEW
PT Hangge MD, HE Kosiorek MS, JM Chang MD, RJ Gray MD, N Wasif MD, CH
Stucky MD, DW Northfelt MD, KS Anderson MD PhD, AE McCullough MD, IT
Ocal MD, BA Pockaj MD
Phoenix, AZ
Background: Inflammatory breast cancer (IBC) accounts for approximately 1.0-2.5%
of all breast cancer diagnoses and carries a poor prognosis. Current treatment involves
tri-modality therapy with neoadjuvant chemotherapy, surgery and radiation therapy.
Additional endocrine and targeted therapy are used as indicated. The goal of this
study is to determine clinical history and outcome of patients at our institution in the
modern era.
Method: A retrospective review of a prospectively collected database of women with
breast cancer who underwent neoadjuvant treatment from 2002-2015 was performed.
A total of 37 patients were identified with IBC. Patient factors, tumor factors and
response were analyzed. Kaplan-Meier curves were performed to show overall survival
and survival based on tumor marker status.
Results: A total of 289 breast cancer patients underwent neoadjuvant therapy; 37
(13%) had IBC. Mean age was 59.2 (range 40-74) and 74% were postmenopausal.
Race was comprised of white (90%), Hispanic (8%), and Native American (3%). Mean
BMI was 29.4 (range 19.9-41.2). Mean follow-up time in years was 1.2 (0-8.2). Tumor
markers were 40% ER+Her2-, 32% Her2+, and 29% triple negative breast cancer
(TNBC). Histologically, 73% were invasive ductal carcinoma (IDC), 5% invasive
lobular carcinoma (ILC), 5% mixed IDC/ILC and 16% other. Most presented at Grade
3 (62%) and others were Grade 2 (27%) or Grade 1 (3%). 5 patients presented with
stage IV disease and 3 presented with recurrent breast cancer. Most patients presented
with clinically positive lymph nodes (N0 27%, N1 27%, N2 30%, N3 16%). All
patients underwent pre-operative chemotherapy. All patients underwent a mastectomy
except for one patient who refused mastectomy despite counseling and chose to pursue
lumpectomy. Axillary staging after chemotherapy was a planned axillary lymph node
dissection (ALND) in 64%, sentinel lymph biopsy followed by ALND in 28%, SLN
biopsy only in 3% and no axillary procedure in 3%. Only 1 did not undergo an axillary
staging due to patient preference on risk of lymphedema. After chemotherapy, breast
complete pathologic response was found in 9 patients (24%). Angiolymphatic invasion
was persistent at final pathology in 57%. Most patients had residual disease within the
axilla (66%), but 5 patients (15%) had a complete response. TNBC was most likely to
recur overall, 8/13 (61.5%), and more likely to recur to distantly, 4/13 (30.8%). Overall
survival at 5 years for those who presented with stage III disease was 46.5% (n = 38). 5
year survival for ER+/Her2- was 66.7% (n = 15), Her2+ 46.9% (n =12), 2 year survival
was 28% (n = 11) for TNBC (Figure 1).

Conclusion: Despite advances in screening and treatment, IBC continues to carry a
high mortality rate. At our institution, ER+/Her2- IBC had the highest overall survival
and TNBC had the highest mortality, local and distant recurrence rates. This difference
in response among tumor markers underscores the importance of tumor biology to
tailor IBC treatment in the future.

QS 28. SURGICAL OUTCOMES OF LYMPHADENECTOMY IN THE
ELDERLY MELANOMA POPULATION
T Weidner MD, CC Stucky MD, B Pockaj MD, R Gray MD, N Wasif MD, A
Mangold MD, J Jakub MD, S Bagaria MD
Phoenix, AZ
Background: Lymph node dissection (LND) for macroscopic metastatic or recurrent
melanoma is the standard of care. LND is associated with substantial risks and
therefore its use in micrometastatic disease identified on sentinel lymph node (SLN)
biopsy or as a prophylactic treatment is currently under investigation. We reviewed our
surgical outcomes of LND in the elderly melanoma population to examine whether this
group has a higher risk of postoperative complications.
Method: A retrospective review was performed on elderly patients (≥65 years of
age) with a diagnosis of cutaneous or subungual melanoma who underwent LND at
three Mayo Clinic sites from 2005-2015. Surgical and oncologic outcomes were the
compared to a single-site cohort of patients <65 years of age.
Results: 88 elderly patients underwent 111 LND for melanoma (42% neck, 30% axilla,
28% groin). Primary tumor thickness was T1 in 13 (15%) patients, T2 in 14 (16%)
patients, T3 in 32 (36%) patients, T4 in 13 (15%) patients, T-in situ in 1 (1%) patient
and 15 (17%) patients had either unknown primary tumors or not-reported outside
pathology. Indications for LND included positive sentinel node (45%), initial palpable
metastatic disease (18%), recurrence to regional nodal basin (32%), and prophylactic
LND at time of primary excision (5%). All patients undergoing prophylactic LND
did not have identification of metastatic disease in any of the lymph nodes examined.
The median length of drain placement was 12 days (range 0-150 days). Complications
included nerve injuries (19%), infection (13%) seroma (13%), wound dehiscence (4%),
and chyle leak (3%). Median length of hospital stay was 2.4 days (range 0-22 days),
significantly longer than for patients <65 years (1.5 days, p=0.0029). Lymphedema was
noted in 38% of elderly patients (36% upper extremity vs. 54% lower extremity), which
was significantly higher than among patients <65 years (18%, p=0.0185). The 30-day
readmission rate was 11% versus 10% for younger patients.
Conclusion: Elderly melanoma patients experience noteworthy postoperative
complications after LND. These results along with those from upcoming trials of
the need for completion lymph node dissection after a positive lymph node will aid
in our ability to make appropriate decisions of whether or not to pursue LND in
our melanoma patients especially in light of the associated morbidities especially in
the elderly where the risk is somewhat higher. The use of prophylactic lymph node
dissection should be discouraged.

QS 30. SPECT-CT impacts surgical and radiographical approach in sentinel
lymph node biopsy for head and neck melanoma
BB Trinh MD, BC Chapman MD, A Gleisner MD PhD, JJ Kwak MD, R Morgan
MD, MD McCarter MD, C Gajdos MD, N Kounalakis MD
Aurora, CO
Background: Detecting metastasis in a sentinel lymph node (SLN) in cutaneous
melanoma predicts overall survival. Previous studies have shown that traditional
pre-operative imaging in the form of 2-D planar lymphoscintigraphy (PL) has a
lower detection rate of SLN in head and neck melanoma compared to other primary
sites. The addition of single-photon emission computed tomography (SPECT-CT)
significantly increases the likelihood of retrieving a positive SLN in this patient subset.
This study aimed to examine whether SPECT-CT alters a surgeon’s incisional approach
and ability to locate the SLN intra-operatively in cutaneous melanomas of the head and
neck.
Method: Patients who underwent SLN biopsy for cutaneous melanoma between
November 2011 and October 2016 were included in a prospectively collected,
retrospectively reviewed database. Surgeons were given a survey to complete postoperatively that asked whether SPECT-CT: a) influenced the incision for SLN, b)
influenced the extent of incision, and c) helped distinguish a SLN difficult to visualize
on PL due to proximity to the primary tumor site. Only patients who underwent SLN
biopsy for head and neck primary melanoma were included. Patient demographics
and pathologic outcomes were analyzed in comparison to surgeon responses using
chi-square test for categorical variables and Wilcoxon rank-sum test for continuous
variables.
Results: Surgeon responses were available for 71 head and neck melanoma patients.
Mean age was 58.9±17.9; 49 were male (69%); primary locations included scalp
(33.8%), ear (14.1%), face (42.3%), neck (8.5%), and conjunctiva (1.4%). Biopsy
depth was 2.6±3.2 mm; ulceration was present in 11 (15.5%); mitosis was present in
57 (80.3%). Surgeons responded that SPECT-CT influenced their incision in 58 cases
(81.7%), influenced the extent of incision in 33 cases (46.5%), and helped distinguish
a SLN difficult to visualize on PL due to proximity to the primary tumor site in 27 of
70 cases (38.6%). SPECT-CT most commonly improved localization of the SLN due
to proximity of the primary tumor in melanomas of the face (11 patients) and scalp (10
patients). These responses did not have a statistically significant association with any
patient characteristics or pathologic variables.
Conclusion: According to a questionnaire answered by surgeons who performed SLN
biopsy for cutaneous melanoma of the head and neck, SPECT-CT has been shown
to influence the incision, extent of incision, and improve identification of SLNs near
the primary tumor site. This study supports the notion that SPECT-CT is a useful
adjunctive modality in SLN biopsy for cutaneous melanoma of the head and neck.

QS 31. EARLY EXPERIENCE WITH CYTOREDUCTION AND
HYPERTHERMIC INTRAPERITONEAL CHEMOTHERAPY AT A NEWLY
DEVELOPED CENTER FOR PERITONEAL MALIGNANCY: LESSONS
LEARNED FROM THE FIRST 50 CASES
Whitney Guerrero MD, Gitonga Munene MD, Paxton V. Dickson MD, John Mays
BS, Dina Darby RN/NP, Donna Freeman RN, David Shibata MD, Evan S Glazer
MD, Jeremiah L. Deneve DO
Memphis, TN
Background: Peritoneal carcinomatosis (PC) was previously considered a terminal
condition and is the pattern of metastasis for a variety of malignancies including
appendiceal, ovarian and colon cancers. Cytoreductive surgery and hyperthermic
intraperitoneal chemotherapy (CRS/HIPEC) has significantly improved outcomes
for appropriately selected patients. We present our cumulative experience and lessons
learned from the initial completed 50 CRS/HIPEC procedures in a newly developed
center for peritoneal malignancy.
Method: After IRB approval, a single-institution retrospective review was performed
for the first 50 patients treated with CRS/HIPEC. Clinicopathologic variables and
outcomes data were recorded. Twenty-six pts (34%) who underwent attempted CRS/
HIPEC were excluded as excessive disease (CCR 3) resulted in incomplete CRS (IC
CRS/HIPEC) and HIPEC was therefore not performed.
Results: Patients treated with CRS/HIPEC were Caucasian (66%), female (64%) with
a median age of 53 years (11-73 years). Primary pathology included: appendix (42%,
n=21), ovary (18%, n=9), colon (14%, n=7), desmoplastic small round cell tumor (14%,
n=7) or other (12%, n=6). The median peritoneal cancer index (PCI) score was 15.5 (139). Forty-five patients (90%) underwent multivisceral resection and 92% underwent
complete cytoreduction (CCR 0/1). Median hospital length of stay was 9.0 days (6-35
days). Twenty-one patients (42%) experienced a complication, 8 (16%) major morbidity
(Clavien-Dindo 3-5) with 2 (4%) 30-day mortalities. With a median follow up of 18.5
months (1-49 months), recurrence-free survival was 14.1 months (95% CI: 11.1, 17.2
months) and overall 1-, 2- and 3-year survival was 82%, 54%, and 33%, respectively.
Recent additions to improve outcomes included the addition of a dedicated CRS/
HIPEC coordinator to facilitate patient flow and coordination. Furthermore, the
development of a goal-directed fluid therapy protocol (GDFT) was instituted with
anesthesia assistance to attempt to shorten recovery and hospital stay. Physical therapy
and nutritional assessment protocols were developed to improve early postoperative
mobilization and optimize recovery. Selective use of diagnostic laparoscopy (DL) was
instituted for high-grade appendiceal and colon malignancies as these pathologies were
more often associated with IC CRS/HIPEC.
Conclusion: Short-term outcomes observed after CRS/HIPEC in a newly developed
center for PC are consistent with published higher volume center experiences. Hiring a
CRS/HIPEC coordinator has proven instrumental in facilitating patient coordination,
scheduling of preoperative studies and adherence to protocols. Appropriate patient
selection, selective use of DL, institution of GDFT protocols with preoperative
nutritional and physical therapy assessments will hopefully yield improved outcomes as
experience develops.

QS 32. A NSQIP ANALYSIS OF CRS-HIPEC OUTCOMES COMPARED TO
OTHER MAJOR GASTROINTESTINAL SURGERIES
R Sleightholm BS, L Smith PhD, A Patel MD, and JM Foster MD
Omaha, NE
Background: Currently less than 15% of patients with peritoneal metastasis who
are candidates for cytoreductive surgery (CRS) with HIPEC are referred for surgical
evaluation. One misconception that remains a major barrier for appropriate patient
referral is the perceived high morbidity and mortality of CRS-HIPEC, while major
gastrointestinal surgeries with similar morbidity and mortality rates such as whipple,
hepatectomy, and esophagectomy have become the standard of care. Utilizing the
NSQIP database the safety of CRS-HIPEC was evaluated in a comparative outcomes
analysis to determine the relative safety.
Method: A retrospective review of the NSQIP data base (2005-2014) was performed
to identify patients who underwent CRS (1700), hepatectomy (23,579), whipple
(13755), and esophagectomy (6524). Hepatectomies compared included trisegmental
hepatectomy (TSH 2079) and right lobe hepatectomy (RLH 4262). Records were
analyzed for rates of return to OR (RtOR), superficial infection (SI), deep incisional
infection (DII), organ space infection (OSI), length of stay (LOS), and 30 day
mortality. LOS was analyzed using analysis of variance (ANOVA) and Tukey
adjustment for pairwise comparisons. Chi-square testing was performed on all other
binary data.
Results: Compared to CRS-HIPEC, rates of RtOR were higher for esophagectomies
(P<0.001); SI were higher in whipple and esophagectomies (P<0.001); and OSI
were higher for RH, TSH, and whipple (P<0.0001, 0.03, <0.0001 respectively).
LOS for CRS was 9.8 days which was lower than whipple, 13.2 days (P<0.0001),
and esophagectomy 14.7 days (P<0.0001). Overall 30 day mortality was 1.24%
in CRS which was lower than TSH (4.38%), RLH(3.38%), whipple (2.65%), and
esophagectomy (3.10%), P<0.001.
Conclusion: In this comparative safety analysis of major NSQIP morbidity metric,
CRS-HIPEC had either comparable or improved observed outcomes. The LOS was
lower compared to both esophagectomy and whipple procedures but comparable to
TSH and RH. Lastly, CRS-HIPEC had the lowest observed mortality rates. In this
comparative analysis, CRS-HIPEC had the lowest complication, and safety concerns
should not be an obstacle to patient referral.

NEOADJUVANT STEREOTACTIC BODY RADIATION THERAPY VERSUS
INTENSITY-MODULATED RADIATION THERAPY IN PANCREATIC
ADENOCARCINOMA

MD, C Meguid DNP, C Bartsch PA, T Schefter MD, K Goodman MD, C Gajdos
MD, RD Schulick MD, BH Edil MD, MD McCarter MD
Aurora, CO
Background: Neoadjuvant chemoradiotherapy is increasingly used in borderline
resectable pancreas cancer to facilitate surgical resection. We compared perioperative
outcomes and survival in patients receiving neoadjuvant stereotactic body radiation
therapy (SBRT) with those receiving intensity-modulated radiation therapy (IMRT).
Method: We analyzed institutional data in patients receiving neoadjuvant SBRT or
IMRT for pancreatic adenocarcinoma (2012-2016). A chi-squared test was utilized for
categorical variables and Wilcoxon rank-sum test for continuous variables. Differences
in progression-free survival (PFS) and overall survival (OS) from date of diagnosis were
compared with a log-rank test.
Results: We identified 54 (76.1%) patients receiving SBRT and 17 (23.9%) receiving
IMRT. The median dose of radiation and duration in the SBRT group was 30 Gy and 9
days, respectively, and 45 Gy and 36 days, respectively, in the IMRT group. Patients in
the SBRT group were more likely to receive neoadjuvant FOLFIRINOX (n=34, 63%)
and gemcitabine/abraxane (n=17, 31%) compared to the IMRT group (FOLFIRINOX
n=9, 53% and gemcitabine/abraxane n=2, 12%) (p=0.007). There was no difference in
the number of patients that made it to surgery and had resectable disease in the SBRT
(n=31, 57%) group compared to the IMRT (n=11, 65%) (p=0.909). Among resected
patients, there was no difference in blood loss, operative time, pancreatic fistula,
abdominal abscess, wound infections, length of stay, 90-day readmission and mortality
(all p>0.05). Although more lymph nodes were examined in the SBRT group (median
19 vs. 13, p=0.008), there was no difference in lymph node status, margin status,
lymphovascular invasion, perineural invasion, or pathologic response to neoadjuvant
treatment (all p>0.05). In the SBRT group, 38 (70.4%) patients had disease progression
compared to 14 (82.4%) in the IMRT Group. Among all patients, median PFS was 11
months in the SBRT group and 15 months in the IMRT group (p=0.211). In resected
patients, median PFS was 18 months in the SBRT group and 20 months in the IMRT
group (p=0.465). Median OS was 23 months in all patients and 25 months in resected
patients; median OS was not reached in the IMRT group.
Conclusion: As part of a neoadjuvant therapy regimen for borderline resectable
pancreatic adenocarcinoma, SBRT and IMRT appear to have similar rates of resection
and perioperative outcomes. Improved understanding of the role for selection bias
and longer follow up are needed to better define the impact of neoadjuvant radiation
modality on PFS and OS.

QS 34. IMPLEMENTATION OF A NURSE-DRIVEN PROTOCOL FOR
CATHETER REMOVAL TO DECREASE CATHETER ASSOCIATED
URINARY TRACT INFECTION RATE IN A SURGICAL TRAUMA
INTENSIVE CARE UNIT
AF Tyson MD, LR Spangler RN, SW Ross MD, EF Campbell RN, CL Passaretti MD,
CE Reinke MD, RF Sing DO
Charlotte, NC
Background: Catheter associated urinary tract infections (CAUTIs) are a significant
source of morbidity, mortality, and cost in healthcare. Early removal of urinary
catheters is one of the most effective strategies for CAUTI prevention; however, under
traditional physician-directed systems, catheters are consistently used longer than
necessary. We hypothesized that a nurse-directed catheter removal protocol would
result in fewer catheter days and a decrease in CAUTI rates in a Surgical-Trauma
Intensive Care Unit (STICU).
Method: We performed a retrospective, cohort study following implementation of
a nursing-driven protocol for early catheter removal in August 2014 in the STICU
at a regional hospital. Under this protocol, nurses performed twice-daily assessment
of all patients with urinary catheters. Catheters were removed when they no longer
met criteria according to the protocol. Data from a 19-month historical control was
compared to data from a 15-month intervention period, following a 2-month washout
period. Pre- and post-intervention CAUTI rate and catheter days were compared.
Results: The study population included 20803 catheter days: 11490 pre-intervention,
1127 in washout, and 8186 post-intervention. A total of 77 CAUTIs occurred during
the study period, with 59 before, 2 in the washout, and 16 after the protocol. Both
CAUTI rate and catheter utilization decreased following implementation of the
protocol (rate 5.06 to 1.95/1000 catheter days, p-value <0.01; utilization 0.78 to 0.70,
p-value <0.01). The CAUTI rate prior to the nursing protocol was 2.6 times greater
than the rate following the protocol.
Conclusion: Implementation of a nurse-driven protocol for early urinary catheter
removal can result in measurable decreases in both catheter utilization and CAUTI
rates and can be a useful adjunct for infection prevention in the STICU setting.

QS 35. LONG-TERM OUTCOMES OF FALLS IN OCTOGENARIANS
TAKING ORAL ANTI-PLATELET AND ANTI-COAGULANT MEDICATIONS
CM Hall MD, S Essler MD, J Dandashi BS, S Wieters MD, D Drigalla MD, K Stone
MD, JL Regner MD
Temple, TX
Background: Falls are the leading cause of traumatic brain injury in elderly patients
and account for over $31 billion annually in Medicare expenses. Oral anti-platelet
(OAP) and anti-coagulant (OAC) medications increase the risk of hemorrhagic events
and mortality in elderly patients following a fall. Many of these patients, however,
are discharged from the Emergency Department (ED) with no obvious injuries and a
normal head CT. The purpose of this study is to characterize long-term outcomes of
falls in octogenarians taking OAP or OAC, including those who were not injured from
their sentinel fall.
Method: A single-institution, IRB-approved, retrospective review of a level I trauma
center was performed on all patients over 80 years old who presented to the ED for
a ground level fall and underwent a head CT between January 2014- January 2016.
Patients taking OAP or OAC were included in the study. Demographic data included
age, medication, place of residence, ambulatory status, and presence of intracranial
hemorrhage identified on CT scan. Primary outcomes were death, readmission,
recurrent falls, and delayed intracranial hemorrhage.
Results: One hundred fifteen patients were identified for inclusion in this study. Mean
age was 86.9 ± 5.0 years (range 80-101), 58% of patients were female, 56.5% lived
at home, and 22.6% of patients were taking OAC, including warfarin, rivaroxaban,
apixaban, dabigatran, and enoxaparin. One hundred patients (86.9%) were taking
OAP, including aspirin, clopidogrel, or both. Demographics and primary outcomes
are shown in Table 1. The incidence of traumatic intracranial hemorrhage was 13.9%
(16 patients). Intracranial hemorrhage was associated with an increased risk of 30-day
mortality (OR: 4.5, 95% CI: 1.3-16.0). Twenty-four of the deceased patients (57.1%)
died within 1 month of the sentinel fall or a recurrent fall. Overall mortality at 6
months following the sentinel fall was 20.8%. Significant risk factors for 6-month
mortality included male gender (OR 2.9, 95% CI: 1.2-7.4), history of congestive
heart failure (OR 3.0, 95% CI: 1.2-7.7), and readmission within 30 days (OR 4.36,
95% CI: 1.5-12.3). Three patients who presented with intracranial hemorrhage had
delayed progression of intracranial bleeding. Delayed intracranial hemorrhage was not
identified in patients who presented with a negative head CT.
Conclusion: Mortality and readmission rates following a ground level fall in
octogenarians taking OAP and OAC medications are high, even in patients with a
negative head CT. Acknowledgement of these outcomes and the likelihood of recurrent
falls should direct goals of care and strategies for rehabilitation. More studies are
needed to determine if this patient population would benefit from individualized care
plans to decrease the burden of recurrent falls.

QS 36. MAJOR VENOUS INJURIES AND VTE: WHAT IS THE RISK?
AE Mendoza MD, MPH, CA Wybourn MD, AR Campbell MD, MM Knudson MD
San Francisco, CA
Background: The true incidence of venous thromboembolism (VTE) after penetrating
venous injuries is unknown and likely related to the approach to the injury (repair
vs ligation), the use of anticoagulants, and post-operative imaging studies which
may introduce surveillance bias. We hypothesized that venous injuries are a major
independent risk factor for VTE and that such patients should receive aggressive postoperative anticoagulation.
Method: This is a retrospective case-control study from 2005-2015 involving trauma
patients with or without penetrating major venous injuries defined as injuries to the
vena cava, iliac and/or femoral veins. The patient groups were matched on ISS and age.
Patients were excluded from the analysis if they died within 24 hours of admission.
Descriptive statistics were performed on demographics, repair technique (ligation or
repair), injury location, VTE and outcomes. Data were analyzed using unpaired t-test
for continuous variables, sign test for categorical variables, odds ratio with chi-squared
analysis and logistic regression.
Results: Over a 10 year period (2005-2015) 49 patients who sustained major
penetrating venous injuries were compared with 70 patients with penetrating injuries
not involving major veins. The mean age (31 vs 29, p=0.50), sex (88% vs 90%
male, p=0.29) and ISS (20 vs 22, p=0.32) were similar between groups. The two
groups had no difference in ICU LOS (p=0.07), hospital LOS (p=0.09) or overall
mortality (p=0.13). However, patients with venous injury did have higher transfusion
requirements (17.2 + 17.3 vs 6.53 + 7.81; p=0.00004) and mechanical ventilation
days (8.57 + 16.41 vs 2.81 + 6.83; p=0.01). DVT rates were significantly higher in
the venous injury group (22% vs 1.42%, p=0.001). The PE rate was also higher in
the venous injury group (8.16% vs 5.71%) but this difference did not reach statistical
significance (p=0.13). On regression analysis, vein injury location was not predictive of
VTE but ligation was (p=0.004). The odds ratio of having a VTE with a major venous
injury was significantly higher (OR 6.6, 94% CI: 1.86-29.16), p=0.0006).
Conclusion: Our study suggests that major penetrating venous injuries are highly
associated with VTE. Further prospective studies are warranted to evaluate the
incidence of VTE in this high risk patient group.

QS 37. ULTRASOUND-GUIDED JUGULAR CENTRAL VENOUS CATHETER
INSERTION IN SEVERELY THROMBOCYTOPENIC CANCER PATIENTS IS
SAFE WITH OR WITHOUT PLATELET TRANSFUSION
Z Al Rstum, MD, TTT Huynh, MD, SY Huang, MD and GT Pisimisis, MD
Houston, TX
Background: Most current consensus statements support the transfusion of platelets
(PLT) from donors to achieve a PLT count of at least 50,000/ μL for safe central venous
catheter (CVC) insertion in thrombocytopenic patients. In patients with hematologic
malignancies, CVC is often required for treatment. Routine PLT transfusion to reach
the recommended threshold prior to CVC insertion in these patients can lead to delay
in treatment and deplete the scarce supply of PLT. We sought to assess the incidence of
bleeding after ultrasound-guided internal jugular (USGIJ) CVC insertion in severely
thrombocytopenic cancer patients, with and without PLT transfusion, and to identify
possible risk factors for peri-procedure bleeding.
Method: This is a retrospective study of consecutive cancer patients with severe
thrombocytopenia (PLT count <50 x 10/ μL) who underwent USGIJ CVC insertion
(December 2014-September 2016) in single tertiary referral cancer center. Patients
were divided into two groups based on whether they received PLT transfusion prior
or during the procedure (peri-procedure). The decision to administer peri-procedure
PLT transfusion for CVC insertion was made by the primary oncology team. Our
analysis included descriptive statistics, t-test and Fisher›s exact test for continuous and
categorical variables respectively, Spearman›s correlation and multivariate regression
analysis for predictors. Statistical significance was at P<.05.
Results: A total of 52 patients had USGIJ CVC placement. Peri-procedurally, 28
patients received at least 4 packs of PLT (200 ml) transfusion (Group A), and 24
patients received no PLT (Group B). Demographics, baseline comorbidities and
procedural characteristics were equally distributed between the groups. Mean age of
cohort was 53±16 year-old, mean body mass index (BMI) 27±7, median CVC size 12 F
(IQR:6). In 20/52 (38%) patients CVC was tunneled. There were 29/52 (56%) patients
diagnosed with acute myelogenous leukemia (AML) and 23/52 (44%) with other
hematologic malignancies. Mean PLT count before transfusion was 21.4±13 x10 /μL
in group A and 26.9±11 x10/ μL in group B, P=.054. After transfusion the PLT count
was 31.7±18 x10 / μL in group A, and 26.9 ±10 x10/ μL in group B, P=.137. There was
a mild trend towards peri-procedure PLT transfusion in patients with lower PLT count
(rho= -0.237, P=.091). Overall, 10/52 patients (19%) had postoperative minor bleeding,
but none with major bleeding. There was no significant drop in hemoglobin level in
either group A or B. The incidence of post-procedure bleeding was similar in both
groups (21% vs. 17%, P=0.736). Higher PLT count was protective (Odds ratio [OR]
0.85, 95%CI 0.74-0.98, P<.03). Larger CVC French size was associated with higher risk
of bleeding ( [OR] 1.86, 95% CI 1.01-3.39, P<.05). There was a trend towards bleeding
with AML diagnosis ([OR] 9.97, 95% CI 0.92-107.51, P=.058) and age ([OR] 1.07,

95% CI 0.99-1.18, P=.083). Gender, BMI, renal dysfunction and tunneled insertion
were not significant predictors.
Conclusion: The results of our study show that ultrasound guided internal jugular
CVC insertion has low incidence of minor bleeding in severely thrombocytopenic
patients. Furthermore, our study suggests that peri-procedural platelet transfusion can
be limited to patients with identified risk factors, such as for patients with the diagnosis
of AML or needing large bore CVC.

QS 38. COAGULOPATHY OF HEMORRHAGIC SHOCK IN A LETHAL
SWINE MODEL: TRANSITION FROM FIBRINOLYSIS TO FIBRINOGEN
AND PLATELET DYSFUNCTION
BR Huebner MD, HB Moore MD, P Lawson BS, G Nunns MD, G Stettler MD, M
Fragso DVT, PM Einersen MD, CC Silliman MD, PhD, A Banerjee PhD, EE Moore
MD
Aurora, CO
Background: Trauma-induced-coagulopathy (TIC) is associated with increased
mortality, with hyperfibrinolysis being the most lethal form of TIC. Animal models
have focused on long durations of moderate shock and have failed to establish
a reproducible TIC. The combination of severe hemorrhagic shock followed by
resuscitative balloon endovascular occlusion of the aorta (REBOA) allows for neardeath hemorrhage followed by continued buildup of ischemic mediators while
sustaining blood flow to vital organs. We hypothesize that a fast severe hemorrhagic
shock will induce a short period of hyperfibrinolysis followed by REBOA and saline
resuscitation resulting in a separate unique coagulopathy.
Method: Swine were anesthetized and access obtained (n =6). A short period of
controlled hemorrhage and severe shock (MAP<25) was instituted followed by
Zone 1 REBOA. After 15 minutes of balloon occlusion, the REBOA was deflated
and resuscitation ensued with 1200cc normal saline (NS). Pigs were monitored for
15-minutes followed by two additional 5-minute REBOA occlusions and deflation
with 600cc NS resuscitation with 30 minutes of monitoring. Blood was drawn over
the duration of the experiment for ABG, BMP, and thromboelastography (TEG).
TEG parameters were analyzed using Friedman test over the course of the experiment.
Values described as mean ± SD.
Results: Median blood loss was 62% total blood volume resulting in 50% mortality
(prior to saline resuscitation). The survivors established a significant acidosis with
a median pH of 7.18 and base deficit of 18 at the end of the experiment. Increased
fibrinolysis was seen at the post-hemorrhage time-point, with an LY30 (lysis at 30
minutes) of 3.2±1.9% as compared to baseline (1.0±0.7%, p=0.025) and the end of
the experiment (0.03±0.08%, p=0.079). Of the survivors, REBOA in combination
with saline resuscitation resulted in slower clot formation (angle 15-minutes postNS infusion #1 30.5±8.9°) compared to baseline (55.7±5.1°) and post-hemorrhage
(61.2±17.7°) (p=0.008), as well as decreased clot strength (maximum amplitude (MA)
58.0±6.9mm) compared to baseline (80.8±1.0mm) and post-hemorrhage (76.3±2.8mm)
(p=0.013). These abnormalities persisted over the duration of the experiment.
Conclusion: Hyperfibrinolysis (increased LY30) is seen early in hemorrhagic shock
while fibrinogen dysfunction (decreased angle) and platelet dysfunction (decreased
MA) occur later, likely resulting from prolonged acidosis, ischemia-reperfusion injury,
and NS resuscitation.

QS 39. HIGHER PAIN SCORES TRIGGER THE INITIAL ONSET OF
POSTOPERATIVE DELIRIUM
DM Overbey MD, BC Chapman MD, SA Hilton MD, EL Jones MD, TN Robinson
MD, TS Jones MD
Denver, CO
Background: Postoperative delirium is a common surgical complication with direct
adverse effects on morbidity and mortality. Increased pain has been implicated as
an etiology of postoperative delirium, but limited evidence exists in support. Prior
studies have implicated adjunctive and global pain control to have a positive impact
on delirium prevention. Our purpose was to identify factors temporally antecedent
to delirium onset with the goal of identifying triggering events. We hypothesize that
uncontrolled pain can cause delirium, and thus be used in a goal-directed fashion to
prevent delirium onset.
Method: Patients aged 60 and older undergoing major elective operations requiring
postoperative intensive care admission were included (n=325). A post-hoc analysis was
performed to examine postoperative risk factors associated with the initial onset of
delirium. Each delirium event was defined by the onset of new delirium (n=226), and
that individual patient-day was evaluated for triggering events compared to delirium
free days (n=1,188). Univariate analyses compared factors associated with delirium,
followed by multivariable logistic regression analysis to analyze the impact of pain
scores on triggering delirium.
Results: 301 patients were included with an average age of 69 years. Daily pain scores,
Richmond agitation sedation score (RASS), ventilator dependency, labs, and oxygen
saturation are reported in Table 1. Pain scores measured at the initial onset of delirium
averaged 4.1±2.8 compared to 2.9±2.3 for days without delirium (p<0.001). Each
unit of elevation in pain score was independently associated with a 12% increase in
delirium onset (OR 1.12, 95% CI 1.05-1.19). Interactions with delirium and pain score
maintained ≤4/10 proved to be protective of delirium with incidence rates declining
from 16% to 9% (p=0.012).
Conclusion: In post-operative ICU patients, the initial development of delirium
is significantly associated with higher pain scores. Increased pain scores are a valid
independent predictor for the initial onset of delirium. The importance of these
findings is that because pain can be treated, alleviating pain may prevent the initial
onset of delirium. The data suggests that a goal of reducing pain scores to less than
4/10 may minimize delirium risk. Post-operative goal-directed pain control may have a
protective effect against delirium.

QS 40. FUTILITY NO MORE: CRITICALLY INJURED TRAUMA PATIENTS
WITH SEVERE ACIDOSIS
V Karun BS, NM Tapia MD, R Campana BS, EA Alore MD, BG Scott MD, SD
Gordy MD, CT Wilson MD, SR Todd MD, JW Suliburk MD
Houston, TX
Background: Severe acidosis in trauma is a poor prognostic indicator. Historically
these patients are reported to have an extremely high mortality rate, with some
regarding attempts at salvage of a patient with initial pH < 7 as futile care. The purpose
of this study was to evaluate mortality in patients presenting with severe acidosis. We
hypothesized that severe acidosis (pH < 7.1 on the initial arterial blood gas [ABG])
would result in a 30-day mortality rate less than 50%.
Method: This is a single center retrospective review from an urban level 1 trauma
center. All level I trauma activations with an emergency center systolic blood pressure
(SBP)<100mmHg from 2006-2015 were reviewed. In addition to ABG data, variables
collected included demographics, mechanism of injury, injury severity score, and
30-day mortality. Variables were analyzed using Student’s t-test and Chi-square. For
acidosis analyses we arbitrarily selected 3 ABG pH cut points: < 7.1, < 7.05, < 7.0.
Results: There were 1,537 level I trauma activations with an initial SBP<100mmHg.
Patients who were pronounced dead on arrival, had computed tomography evidence
of a devastating head injury with Glasgow Coma Scale (GCS)<8, and those with no
ABG were excluded. This left 74 patients with pH<7.1, 64 with pH<7.05, and 39 with
pH<7.0. Mortality for patients with a pH<7.1, pH<7.05, and pH<7 was 42%, 45%,
and 51%, respectively (p=0.071). Gender, race, MOI, and initial base excess were not
significantly different among deaths or survivors. The mean ISS was significantly higher
(p<0.021) and mean GCS significantly lower (p<0.029) in deceased patients at each
pH cut-point (table). Patients with a pH<7.1 had overall, blunt, and penetrating injury
mortality rates of 42%, 48%, and 39%, respectively, which was significantly higher
than patients with a pH>7.1 whose overall, blunt, and penetrating mortality rates were
8%, 7%, and 8%, respectively (p<0.001 for all comparisons).
Conclusion: Level I trauma activations with a SBP<100mmHg, without evidence of
severe head injury and with severe acidosis, had significantly higher mortality rates than
those without severe acidosis. However, the majority of these patients survived. Thus,
an initial pH<7.1 or is not futile in modern trauma care.

QS 41. AN EFFECTIVE MODEL FOR PROVIDING ACCESS TO SURGICAL
CARE TO THE UN- AND UNDER-INSURED
SC Walling BE, JC Heimroth MS, SK Edwards BA, EH Sutton MD
Louisville, KY
Background: The uninsured and underinsured population’s lack of access to necessary
surgical care in the United States is well documented in the literature. Despite
modern healthcare reform efforts, including the Affordable Care Act, the emergency
department remains the only option for many Americans seeking surgical care. To
address this deficit in the healthcare system, Surgery on Sunday Louisville (SOSL) was
established in February 2013 and provides free outpatient surgery to this population
in Louisville, KY. The aim of SOSL is to serve uninsured and underinsured patients
seeking care by acting as a referral resource, increase access to surgical care through
SOSL’s monthly ambulatory clinic, and allow this population to obtain timely care
through SOSL’s free surgical events. Our objective is to show that SOSL’s model is an
effective method of attaining these goals.
Method: In a retrospective cohort study using data from SOS-L’s secure database,
the initial outcomes of the program from October 2013 to October 2016 were
analyzed, including the utilization of SOS-L’s services, the patients’ demographic,
financial, social, and medical parameters, and the spectrum of surgical and endoscopic
procedures performed.
Results: In the first 36 months of operation, SOSL received 134 surgical referrals from
18 distinct referral sources. The number of referrals received has increased annually
with 29 in the first year, 50 in the second, and 55 in the third. The referred population
was 53.7% male with a mean age of 41.2 years and a range of ages from 1 to 87 years.
96.3% were uninsured, and the average patient’s financial situation placed him/her at
24% of the federal poverty level with an average annual household income of $10,001.
Only 29.9% were registered US residents, and 82.1% were Hispanic. 34% of referred
patients were not included in the program due to patient refusal (62%) and medical
(21%) and financial (9%) exclusions. In the first 32 months of the program, 58 patients
were provided consultation in a physician’s private office (mean 1.8 encounters/month);
however, in the most recent 4 months, SOSL has established its own ambulatory clinic,
in which 42 patient encounters have occurred (mean 10.5 encounters/month). 68
patients have undergone 70 surgical procedures: 10 in the first year, 26 in the second,
and 34 in the third. The most common procedures were inguinal hernia repairs (14),
cholecystectomies (12), and umbilical hernia repairs (7). 99% of patients were provided
a follow-up visit with 1 patient lost to follow-up. There were no complications requiring
overnight hospitalization or readmission. 8 patients remain in SOSL’s queue awaiting
future surgical services.
Conclusion: SOSL’s model is an effective method of serving the un- and under-insured
who seek care by acting as a growing referral resource, permitting access to surgical
care through its highly effective ambulatory clinic, and allowing patients to obtain care
through its free surgery events.

QS 42. ELIMINATION OF ROUTINE CHEST X-RAY AFTER IMAGE
GUIDED CENTRAL VENOUS ACCESS PORT PLACEMENT IS SAFE AND
COST EFFECTIVE
AR Cannon MD, MC Mone RN, CL Scaife MD, EW Nelson MD
Salt Lake City, UT
Background: Safe, durable, central venous access remains a vital component of care
for those in need of long-term access. Historically, central venous access ports (CVAP)
have been inserted without real-time imaging and a post-procedure chest x-ray (CXR)
utilized to ensure proper positioning and exclude complications. Since the adoption
of intraoperative ultrasound and fluoroscopy, the necessity and benefit of obtaining
a CXR on all patients has been questioned. To confirm the practice of eliminating a
standard CXR, we performed a cohort study to examine the benefit and cost of routine
CXR after guided CVAP placement.
Method: A retrospective cohort study of CVAP procedures using fluoroscopy in the
operating room (OR) was conducted. Data was collected for two consecutive year-long
periods for CVAP procedures performed by two experienced general surgeons. We
compared a historical control group that routinely received post-procedure CXR (Oct.
2011-Oct. 2012), to a second group (No-CXR) in whom a CXR was obtained only for
clinical indications (Oct. 2012-Oct. 2013). Variables included: demographics, body
mass index (BMI), diabetes, access site, anesthesia, OR time, complications, and use of
post-procedure CXR.
Results: A total of 498 patients were included: 292 (58.6%) in the historical CXR
cohort and 206 in the No-CXR group (41.4%). Groups were not different with regards
to age, BMI, diabetes, ASA score (1-2 vs 3-4), OR time, and anesthesia. In the NoCXR group there were significantly more attempted access sites (1.1 vs. 1.0, p=0.02),
and subclavian lines placed (5.8% vs 2.1%, p=0.03). There was a 0% rate of acute
pneumothorax and/or hemothorax in the entire cohort. There was no difference in
catheter placement complications (arterial stick or anatomic misplacement), 1.4% in
historical group vs 2.9% in the No-CXR group, p=0.19. In the historical group, five
patients did not receive a post-procedure CXR (1.7%). In the No-CXR group, nine
patients received a CXR (4.4%), three of which were unrelated to CVAP placement and
six done for clinical indications related to difficult line placement or anatomy. There
were a total of 197 CXR (95.6%) that were safely deferred with no adverse clinical
consequences.
Conclusion: Cost savings related to unnecessary testing is an important goal
in healthcare. Imaging performed at the time of CVAP placement, can result in
substantial savings based on the cost of radiographs, professional fees, and coincident
staffing needs. The estimated cost of a single CXR is variable, but reports range from
$100 to $150, resulting in potential savings of up to $30,000 in this sample alone. We
conclude that when using fluoroscopy guided CVAP placement, additional imaging
with CXR is unnecessary unless indicated due to questions related to difficult line
placement, including multiple access attempts or sites, or clinical symptoms. Given the
considerable number of CVAP used in patient care throughout the healthcare system,
this savings could be significant.

QS 43. ACS-NSQIP RISK CALCULATOR ACCURATELY PREDICTS
COMPLICATIONS IN VENTRAL HERNIA REPAIRS DESPITE THE LACK
OF HERNIA SPECIFIC RISK FACTOR INPUT
MM Mrdutt MD, AN Patel BS, CL Isbell MD, Y Munoz-Maldonado PhD, JL Regner
MD
Temple, TX
Background: Risk stratification is critical when counseling ventral hernia patients.
While the ACS-NSQIP surgical risk calculator predicts risk across a range of
complications, it does not account for hernia specific factors such as hernia size,
infected mesh, or number of prior repairs. Our study evaluates the accuracy of ACSNSQIP calculator in ventral hernia patients with attention to hernia size and previous
abdominal surgery.
Method: An IRB-approved, single institution, retrospective review of ventral hernia
repairs (VHRs) from January 2014 through February 2016 was performed. Inclusion
criteria were elective open or laparoscopic VHRs: initial or recurrent, reducible or
incarcerated, umbilical, epigastric, spigelian and incisional. NSQIP database was
queried for demographics and 30 day outcomes (Table 1). Chart review provided
surgical history and hernia fascial defect surface area (SA). A risk profile was calculated
for each patient using the ACS-NSQIP surgical risk calculator. Brier scores, which
measure the accuracy of probabilistic models based on observed versus predicted
outcomes, were calculated for each complication. Brier score closer to 0 reflects a
more accurate model. Planned sub-group analysis for surgical site infections (SSI)
and readmission compared predicted risk by hernia SA subgroups, previous open or
laparoscopic surgeries and prior hernia repair. Wilcoxon-Rank-Sum test compared the
distribution of predicted risk with significance at p<0.05.
Results: 388 patients were included. Median age was 54, and the cohort had the
following comorbidities: 187 (55.3%) BMI > 29.9, 40 (11.8%) diabetes, 145 (42.9%)
hypertension and 73 (21.6%) current or recent tobacco use. 136 (40.2%) of patients
had undergone previous open abdominal surgery, 117 (34.6%) previous laparoscopic
surgery and 55 (16.3%) at least one previous abdominal hernia repair. 205 (60.7%)
patients had a hernia with fascial defect SA < 2 cm2, 68 (20.1%) 2-5 cm2 and 65
(19.2%) >5 cm2. 185 (54.7%) cases were laparoscopic. Observed complications were
lower than predicted in all complications (see Table 1) except readmission rates (3.55
vs 3.0%, Brier score 0.033) and cardiac complications (0.3 vs 0.1%, Brier score 0.003).
This low complication rate prevented direct comparison of outcomes and hernia specific
factors. Despite the lack of hernia specific criteria in the ACS-NSQIP calculator,
subgroup analysis of predicted risk by SA and surgical history demonstrated increased
complication risk with previous abdominal surgery, hernia repair, and larger hernia
surface area (all P<0.0001).
Conclusion: ACS-NSQIP surgical risk calculator accurately predicts complications
within our VHR population. When stratified by hernia specific variables not reflected

in the NSQIP calculator, predicted risk increases with increased surface area and prior
abdominal surgeries. These findings suggest current hernia repair CPT codes may
better capture risk of disease than appreciated.

QS 44. INSURANCE STATUS IS ASSOCIATED WITH SURVIVAL IN
PATIENTS WITH METASTATIC CANCER
M Ali-Mucheru, MD, DA Etzioni, MD, MSHS, BA Pockaj, MD, RJ Gray, MD, CC
Stucky, MD, YH Chang, PhD, N Wasif, MD, MPH
Phoenix, AZ
Background: Multiple factors play a role in improving survival outcomes for patients
with metastatic cancer, especially the biologically less aggressive malignancies.
Adequate health care coverage allows for access to multimodal cancer care which
improves survival and quality of life, even though cure is rare. We hypothesize that
patients with metastatic cancer who are underinsured or uninsured have worse survival
outcomes.
Method: Retrospective analysis of the National Cancer Database (NCDB) of patients
diagnosed with Stage IV lung, colorectal, pancreas, breast and prostate cancer from
2003-2011. Survival analysis was conducted using the product limit method and
displayed using Kaplan Meier curves. Overall survival was compared between patients
with different insurance coverage types using a Cox proportional hazards model,
controlling for age, race, sex, education, and income. In a second model chemotherapy,
radiation and surgery were added to control for the influence of treatment.
Results: A total of 799,678 patients with lung (58%), colorectal (14%), pancreas (13%),
breast (8%) and prostate (7%) cancer were included. Most patients were treated at
comprehensive community cancer centers (56%). When compared to patients with
private insurance/managed care, patients who were uninsured or on Medicaid had
lower rates of chemotherapy, radiation and surgery as well as lower overall survival
(Figure 1). On multivariable analyses, being uninsured was associated with a higher
risk of mortality [breast HR 1.41, 95% CI 1.35-1.47, colorectal HR 1.28, 95% CI
1.24-1.33, lung HR 1.29, 95% CI 1.27-1.31, pancreas HR 1.28, 95% CI 1.23-1.33,
and prostate HR 1.73, 95% CI 1.63-1.83] when compared to patients with private
insurance/ managed care. A similar association was also seen for patients on Medicaid
(breast HR 1.35, 95% CI 1.31-1.40, colorectal HR 1.27, 95% CI 1.24-1.31, lung HR
1.21, 95% CI 1.19-1.22, pancreas HR 1.20, 95% CI 1.16-1.23, and prostate HR 1.77,
95% CI 1.68-1.87). After adjustment for use of chemotherapy, radiation and surgery
these differences attenuated but persisted.
Conclusion: Patients with metastatic cancer who are uninsured or on Medicaid
have lower rates of treatment and worse survival in comparison to those with private
insurance. This is especially notable for metastatic colon, breast and prostate cancer,
suggesting that expanding insurance access for these patients may improve outcomes.

QS 46. ESTABLISHING A SYSTEM-WIDE ASSESSMENT OF PREOPERATIVE FRAILTY IN ELECTIVE SURGERY
MM Mrdutt MD, ET Bird MD, CL Isbell MD, RC Frazee MD, HT Papaconstantinou
MD
Temple, TX
Background: Frailty is a promising metric for pre-operative risk stratification. With
reimbursement now linked to outcomes, identification and management of patients
at high risk for poor outcomes is paramount. Correlation of frailty with outcomes
requires baseline measurements within a patient population. Our health care system
implemented a quality initiative to achieve compliance with pre-operative frailty
assessment. This study assesses our success with implementation of this program.
Method: Our Department of Surgery includes 13 surgical subspecialties with more
than 90 surgeons at 4 separate hospitals. Collectively, this group performs >1000
elective operations each month. Recent institutional goals prioritized implementation
of pre-operative frailty assessment in elective surgery patients. Previously validated
frailty assessment included age, gender, body mass index, American Society of
Anesthesiologists Physical Status classification, handgrip strength and recent
hemoglobin value. To facilitate documentation, a frailty calculator was built into our
electronic health record with the score easily imported into clinic notes. Compliance
with frailty measurement was tied to physician compensation, with threshold and high
performance targets set at 70% and >90% compliance. A 3-month education period
(January-March 2016) permitted instruction and work flow optimization. Feedback
was provided during the trial period (April), without impact on compensation.
Performance compliance was linked to compensation starting in May, and defined as
performance month 1 (PM-1). Compliance measurement, reporting and performancebased compensation continued in subsequent months (PM-2, PM-3 and PM-4). Data
was analyzed using Wilcoxon-sign-rank and Kruskal-Wallis tests with significance at p
< 0.05.
Results: Preoperative frailty assessment performance was evaluated for 92 surgeons,
with median surgeon performance over time along with threshold and high
performance targets illustrated in Figure 1. Median surgeon compliance for the system
was 16% in the education period and 75% in the trial period. Compliance during
PM-1 was 88%, with subsequent months showing similar or improved results (PM-2
86%, p=0.055; PM-3 90%, p=0.019; PM-4 87%, p=0.077). Surgical subspecialty and
regional hospital specific analysis revealed no difference from the overall performance
trend (p=0.082 and 0.66, respectively). As of PM-4, 73% of surgeons met threshold
performance when considering all 4 performance months (>70%), of which over ½
achieved high level goal (>90%).
Conclusion: Pre-operative frailty measurement at a system level was successfully
implemented. Performance on quality initiative was tied to physician compensation.
Short-term sustainability was demonstrated over the measured time frame. This
program serves as a model for the implementation and compliance of physician driven
quality metrics.

QS 47. RACIAL AND SOCIODEMOGRAPHIC FACTORS ASSOCIATED
WITH STAGE AT DIAGNOSIS IN PANCREATIC ADENOCARCINOMA
DS Swords MD, C Zhang MS, AP Presson PhD, MA Firpo PhD, SJ Mulvihill MD,
CL Scaife MD
Salt Lake City, UT
Background: Most patients with pancreatic adenocarcinoma (PDAC) are diagnosed
too late for potentially curative resection. Previous studies have shown little to no
association between patient characteristics and stage at diagnosis. Most studies have
compared local disease (stages IA-IB), regional disease (stages IIA-III) and stage IV.
Since > 70% of resected patients are node positive (Stage IIB) and many stage III
patients are not resectable, it would be more clinically relevant to compare Stages IAIIB, which are all technically resectable, to all others. We hypothesized that there are
disparities in being diagnosed at stages I-II by racial and sociodemographic factors.
Method: Patients with PDAC in the Surveillance and End-epidemiology (SEER)
database from 2007-2013 were reviewed. Characteristics of patients diagnosed at stages
I-II were compared to those with stages III, IV, or unknown by a chi-squared test.
Multivariable logistic regression was used to assess factors independently associated
with diagnosis of stages III, IV and unknown relative to stages I-II. Adjusted odds
ratios (ORs) and 95% confidence intervals (CIs) are reported. As a sensitivity analysis,
we repeated these analyses in Stages I-IV only (excluding unknown stage).
Results: There were 43,699 patients available for analysis. The distribution by stages
was: I 6.0%, II 27.1%, III 9.5%, IV 50.6%, and unknown 6.8%. The rates of being
diagnosed at stages I-II were 30.5% for 18-59 year olds vs. 35.6% for >79, 34.7% for
females vs. 31.6% for males, 34.1% for White patients vs. 30.0% for Black and 30.9%
for Hispanic, and 34.3% for those with non-Medicaid insurance vs. 30.7% for those
with Medicaid and 26.0% for the uninsured. The rate of stages I-II varied among the
18 SEER registries from 27.8% in Hawaii to 46.3% in Rural Georgia. There were
annual increases in stages I-II, from 30.3% in 2007 to 34.9% in 2013 (P<0.001, test
for trend). Multivariable logistic regression analysis identified the following associations
with higher stage at diagnosis: young age (OR 1.5, 95% CI 1.4, 1.7), male sex (OR
1.11, 95% CI 1.1, 1.2), black (OR 1.16, 95% CI 1.1, 1.3) and Hispanic race (OR 1.18,
95% CI 1.1, 1.3) relative to non-Hispanic whites, being unmarried (OR 1.07, 95% CI
1.02, 1.1), being uninsured (OR 1.3, 95% CI 1.1, 1.5), living in a low-income county
(OR 1.14, 95% CI 1.04, 1.3), and residing in the Western (OR 1.1, 95% CI 1.02, 1.2)
or Northeastern US (OR 1.3, 1.2, 1.4). Results were similar when unknown stage
patients were excluded. The rate of stage I-II among white patients with non-Medicaid
insurance was 1.5 times higher than in Hispanic uninsured patients (Figure).
Conclusion: Racial and sociodemographic disparities exist in being diagnosed at
a definitively resectable stage in PDAC. This indicates that there is variation in the
quality of diagnostic care received by PDAC patients, and points to an opportunity for
improvement by focusing more on efficient and timely diagnoses.

QS 48. SUSPECTED COMMON BILE DUCT STONE DISEASE: CURRENT
PRACTICE PATTERNS FOR DIAGNOSIS, MANAGEMENT, AND
DEFINITIVE SURGICAL TREATMENT
FZ Zhao MD, WL Biffl MD, JA Pahang BS, GX Zhang PhD, and AU Loengard MD
Honolulu, HI
Background: In the patient with suspected common bile duct (CBD) stone disease,
there are 2 generally accepted methods for definitive treatment: 1) endoscopic
retrograde cholangiopancreatography (ERCP) with subsequent laparoscopic
cholecystectomy (LC) or 2) LC with intraoperative cholangiography (IOC) and
either concurrent CBD exploration (CBDE) or postop ERCP. Prior studies between
the 2 groups reported equivalent clearance rates of CBD stones with 0.5 days shorter
length of stay (LOS) for LC+CBDE. However, current practice patterns for diagnosis,
management, and definitive treatment are still highly varied and institutionally
dependent. The purpose of this study was to characterize current practice in our
institution.
Method: We conducted a single institution retrospective review of admitted
patients with suspected CBD stone disease from July 2013 to September 2015. To
capture this pathology, we selected all patients with diagnoses of biliary pancreatitis,
choledocholithiasis, cholangitis, or cholelithiasis/cholecystitis with elevated total
bilirubin > 1.2mg/dL. From this dataset we evaluated the diagnostic modalities
performed during hospitalization (CT, MRCP, US), number of performed procedures
(ERCP, cholecystectomy, IOC, and CBDE), length of stay (LOS) and hospitalization
cost. Data was analyzed using Kruskal-Wallis Test (p<.05)
Results: Between July 2013 and September 2015, 364 patients were admitted with
suspected CBD stone disease. Average patient age was 58.3 + 17 years. Abdominal US
was performed in 215 patients (59%), abdominal CT in 201 patients (55%) and MRCP
in 77 patients (21%). 151 (41%) patients received 2 or more diagnostic tests prior to
any procedure. 152 patients (42%) underwent ERCP + cholecystectomy (lap or open).
104 (29%) underwent only cholecystectomy (lap or open) with IOC. 26 (7%) of these
patients had concurrent CBDE because of positive IOC findings of choledocholithiasis.
69 patients (19%) underwent only ERCP and were discharged with plans for elective
LC. 39 patients (11%) had normalization of their bilirubin without procedures and
were discharged with plans for elective LC. The median LOS did not differ significantly
between groups of ERCP+LC and LC with IOC + CDBE 5.0 vs 5.2 days (p=.26).
However, the median cost of hospitalization was significantly higher in the ERCP+LC
group $17312 vs $14601 (p<0.0001). The 70% rate of cholecystectomy did not differ
significantly when stratified by total bilirubin level on presentation.
Conclusion: There is wide variation in the approach to suspected CBD stone disease.
Only 70% of our patients received a cholecystectomy during their index admission.

Unnecessary diagnostic testing prior to stone extraction can also lead to increased LOS
and cost. A multi-institutional review could confirm the variation seen in practice
patterns. Ultimately, developing a clinical guideline would streamline the management
of these patients with the potential to shorten LOS and decrease hospitalization costs.

QS 49. DOES SLUDGE ON ULTRASOUND INDICATE CHOLELITHIASIS: A
RETROSPECTIVE REVIEW
EA Shapera MD, MT Nelson MD
Albuquerque, NM
Background: Ultrasound is key in diagnosis of gallstone disease. We sought
ultrasonagraphic determinants predictive of gallbladder pathology to further aide
physicians in the diagnosis of cholelithiasis and cholecystitis. Specifically, we examined
how often an ultrasonic diagnosis of sludge equates to cholelithiasis being indentified.
Method: A retrospective chart review of 500 patients with cholecystectomy was
conducted at the University of New Mexico Hospital Health System. Data was
collected from October 2014 to May 2016 and included presence of diabetes, postoperative symptomatic resolution, age, BMI, gender, laboratory work, findings on
ultrasound and findings on pathology. Cholelithiasis was considered definitively
present if identified in the operative note or the pathology report. A stepwise logistic
regression determined the independent variables associated with our outcomes of
interest: pathologic findings of cholelithiasis, acute cholecystitis, chronic cholecystitis
and necrotizing cholecystitis.
Results: Ultrasonagraphic detection of sludge without stones was predictive of
cholelithiasis found on pathology or intra-operative report 58% of the time (15/26).
Logistic regression found only ultrasonographic finding of stones was associated with
presence of stones on pathology. The addition of sludge to this model did not increase
this association. Logistic regression found that ultrasound findings of distension and
fluid, white blood cell count, patient age, elevated total protein and low albumin to be
associated with the pathology finding of acute cholecystitis, whilst a gallbladder found
to be normal (no fluid or stones etc) was less likely associated with acute cholecystitis.
Ultrasound finding of stones or read as normal was associated with the pathology
finding of chronic cholecystitis, while the ultrasound finding of fluid or diabetes was
less likely. White blood cell count and radiologist interpretation of gallbladder as
“gangrenous” was associated with the pathology finding of necrotizing cholecystitis.
Conclusion: A majority of patients with ultrasound findings of sludge without stones
did have cholelithiasis per pathology report or operative report documenting spillage.
Our logistic regression found the most critical predictor of the pathology finding
of cholelithiasis was ultrasound finding of stones and this was unaffected by the
addition of ultrasound sludge as an independent variable in its modeling. However,
our focus is on finding patients who have false negative ultrasounds, and the finding
of sludge without stones appears to be a substantial false negative for the presence
of cholelithiasis. If patients present consistent with symptomatic cholelithiasis and
ultrasound finding of sludge, even in the absence of stones, cholecystectomy should be
considered.

QS 51. IMPACT OF OPERATION TYPE ON UNPLANNED READMISSION
FOLLOWING COLORECTAL SURGERY IN PATIENTS WITH CHRONIC
OBSTRUCTIVE PULMONARY DISEASE
R Fazl Alizadeh MD, S Sujatha-Bhaskar MD, Z Moghadamyeghaneh MD, JC
Carmichael MD, A Pigazzi MD PhD, MJ Stamos MD
Orange, CA
Background: Patients with underlying pulmonary diseases have higher complication
rates following surgical operations. Given that emergency operation has worse
outcomes compared with elective resections, we sought to evaluate impact of operation
type on unplanned readmission (UR) in chronic obstructive pulmonary disease
(COPD) patients following colorectal resections.
Method: The American College of Surgeons National Surgical Quality Improvement
Program (NSQIP) databases were used to examine the clinical data of patients with
history of COPD who underwent emergent and elective colorectal resections from
2005 to 2014. Multivariate regression analysis was performed to investigate impact of
operation type on UR in such patients.
Results: A total of 10597 patients had preoperative COPD including 5634(53.2%)
patients who had emergent surgery and 4963(46.8%) patients who underwent elective
resections. Mean length of stay was 18±16.57 and 8±8.12 for the patients with emergent
and elective resections respectively (P<0.05).
Patients undergoing emergent surgery had significantly higher mortality (26.7% vs.
2.5%, AOR: 6.01, P <0.0001) and serious morbidity rate (63.2% vs. 26%, AOR: 2.55,
P <0.0001) compared to the elective resection group. Prolonged hospitalization was
higher among patients following emergent procedures (3.2% vs. 1.6%, AOR:0.32:
P=0.01).
Overall rate of UR was 6%. Patients undergoing elective resections had higher rate
of UR compared to emergent cases (8.5% vs. 3.9%, AOR: 0.13, P=0. 001), and also
the highest rate of UR was seen in patients who underwent elective operation and
discharged home within one week of the operation (7.8% vs. 3.1%, P<0.05). However,
most of the emergently operated patients were hospitalized more than one week (68%).
The most common reason of UR was intra-abdominal infection in both elective
(10.7%) and emergent operations (7.4%).
Patients who underwent elective operations had significantly higher rate of colorectal
resections without protective stoma creation (60.5% vs. 39.5%) compared to the
emergent cases. This group of patients also had higher UR rate (8.3% vs. 4%, P<0.05)
compared to the emergent cases.
Conclusion: Emergent operation significantly increases in-hospital mortality and
morbidity rate in COPD patients undergoing colorectal resections. However, UR rate is
significantly higher following elective resections compared to emergent cases. This may
be related to lower rate of protective stoma in elective operations and earlier discharge
of these patients. Further studies are needed to investigate reason of relatively high UR
following elective colorectal operations.

QS 52. THE IMPACT OF FALCIFORM PEDICLE WRAP AFTER
PANCREATICODUODENECTOMY ON POST OPERA-TIVE PANCREATIC
FISTULA
Y Hong MD, J Rostas MD, V Hancock BA, K McMasters MD PhD, P Philips MD, E
Davis MD, R Martin MD PhD, C Scoggins MD MBA
Louisville, KY
Background: Post operative pancreatic fistula (POPF) is a complication that occurs in
up to 30% of pancreati-coduodenectomy (PD) procedures. The falciform ligament is
often utilized as a pedicle flap to wrap around the pancreaticojejunostomy anastomosis
with unclear benefit. We aim to deter-mine the incidence, grade, and time of closure of
POPF after PD in patients with or without falci-form ligament pedicle flap coverage.
Method: A retrospective review of 116 consecutive patients who underwent PD with
or without falciform pedicle wrap from June 2011-April 2016 by six hepatobiliary
surgeons was performed. Postop-erative pancreatic fistula was determined according to
the International Study Group on Pancre-atic Fistula (ISGPF) definition.
Results: A total of 62 (53.4%) patients underwent PD with the falciform ligament
pedicle flap. The overall incidence of POPF was 15.5%, with no difference in the rate of
fistulas between the two groups (p=0.617). There were more minor fistulas (grade A) in
the wrapped group 54.5% vs 0%; p= 0.037). The average time to closure of POPF was
shorter (31.2 +/- 4.36 days vs 41.2 +/- 4.67 ; p=0.166) and had lower need for secondary
percutaneous drainage in the wrapped group (0.09% vs 42.8%; p = 0.245) but did not
reach statistical significance.
Conclusion: Falciform pedicle flap coverage of the pancreaticojejunostomy anastomosis
demonstrated com-parable incidence of pancreatic fistula compared to non-falciform
pedicle flap group. However, when pancreatic fistula occurred, the pedicle flap group
was noted to have lower grade of se-verity with a trend towards shorter time to fistula
closure and lower need for secondary proce-dures. While a randomized control trial
would definitively answer the benefit of a falciform pedi-cle flap, the pedicle flap serves
as a simple way to potentially reduce the morbidity of a pancre-atic fistula.

QS 53. READMISSION AFTER PANCREATECTOMY: CAN IT BE
PREVENTED?
M Bonds MD, T Garwe PhD, B Oluborode MBChB, Z Sarwar MBBS, J Bender MD,
R Postier MD
Oklahoma City, OK
Background: Pancreatectomy has a significant rate of procedure specific morbidity
despite recent improvements in mortality. Morbidity is a predictor of readmission in
this population. As proposals to base insurance reimbursement on quality of care are
being considered, attempts to predict readmission have taken on a new focus. The
goal of this study is to determine what factors are associated with readmission after
pancreatectomy and whether any intervention can prevent intervention.
Method: A retrospective review of a single institution’s pancreatectomies between
January 2011 and April 2015 was performed. Exclusion criteria included subjects
missing data for initial hospitalizations, subjects who died during initial hospitalization
and pancreatectomies done for trauma. Data concerning patient demographics,
intraoperative details, pathology, in-hospital complications, and follow-up were
collected. Grades of delayed gastric emptying (DGE) and pancreatic fistula (PF)
were calculated using the International Study Group of Pancreatic Surgery (ISGPS)
calculator found on the Pancreas Club website. Information regarding 90-day
readmission was gathered as well. Univariate and multivariate analyses were performed
to determine which factors increase risk for readmission.
Results: A total of 257 patients met inclusion criteria. Of these, 84 (32.7%) were
readmitted; the average time to readmission was 21 ± 20.68 days. Based on unadjusted
comparisons, readmitted patients were more likely to have a PF and the incidence
of PF was higher in the readmitted patients across all PF grades (A-C). Surgical site
infections, both deep and superficial, were more common in readmitted patients
(18% vs 6.4%, p=0.0138). There was a trend towards higher prevalence of obesity
(42% vs 33%, p=0.0713) and higher incidence of hospital-induced delirium (11% vs
5%, p=0.0985) among readmitted patients compared to those not readmitted. Upon
multivariable adjustment, only pancreatic fistula (p=0.0005) and BMI (p=0.0793)
remained as significant and marginally significant predictors of readmission,
respectively. A positive dose-response relationship was noted between pancreatic fistula
grade and the odds of readmission, with odds ratios (ORs) ranging from 1.6 (95%
CI: 0.6-4.1) for Grade A to 16.7 (95% CI: 1.8-156.8) for Grade C, albeit with limited
precision.
Conclusion: Readmission after pancreatectomy is a common occurrence despite the
many advancements in perioperative care. Our data suggests that PF and obesity
are risk factors for readmission after pancreatectomy. Presently, these specific factors
are not preventable but may be helpful in counselling patients regarding risk of
readmission. Readmission, however, may not be the best measure of quality to utilize in
the evaluation of pancreatic surgery.

QS 54. NATIONWIDE TRENDS IN ROBOTIC ANTIREFLUX SURGERY
KM Coakley DO, SM Sims MD, T Prasad MA, AE Lincourt PhD MBA, VA
Augenstein MD R Sing DO, BT Heniford MD, PD Colavita MD
Charlotte, NC
Background: In the management of esophageal gastroesophageal reflux disease,
adoption of minimally invasive laparoscopic approaches is particularly widespread.
Robotic surgery offers technologic advances in visualization and dexterity, however,
with increased cost. The purpose of this study was to examine if a similar adoption
trend was seen nationally for robotic-assisted antireflux surgery (RAS) cases, as
previously noted for laparoscopy in antireflux surgery procedures.
Method: The Nationwide Inpatient Sample, which captures approximately ~20% of all
US inpatient admissions, was queried from October 2008 (the inception of the robotic
ICD-9-CM code) to December 2013, for minimally invasive procedures. Outcomes
were compared between laparoscopic and robotic technique over two time periods:
early 2008-09 (T1) and later 2012-13 (T2).
Results: In total, from October 2008-December 2013, 25,150 antireflux surgeries were
performed, 989 (3.9%) robotically. Robotic cases have rose annually with 349 cases
identified in 2013 alone (35.5%).
Between T1 and T2, the total volume of robotic antireflux surgery (RAS) increased
six-fold from 96 to 609. Compared with T1, T2 patients undergoing RAS were older
(54.9±15.3 vs 59.1±14.8; p=0.006) but similar in race, gender and rates of chronic
conditions. Robotic utilization in non-elective admission increased between T1 and
T2 (2.2% vs 10.2 %, p=0.02). There was no change seen in length of stay (LOS),
complications, or mortality. Total costs for RAS related admission significantly
increased between T1 and T2($40,120± $19,004 vs $57,610±$41,197; p<0.0001). Over
this time, RAS was more often performed in zip codes with median income <25k
(10.5% v. 21.4%; p<0.01) and geographically became more common in the South(7.3%
v. 43.0%; p<0.0001).
When comparing laparoscopic antireflux procedures with RAS, there was no difference
in age, gender or chronic conditions in either T1 or T2. In T2, LOS was slightly
greater for robotic procedures (2.8±3.7 vs 2.9±3.2; p=0.02). There was no difference
in complications or mortality between laparoscopic and robotic at either time points.
Total charges were significantly more for robotic procedures in both T1 and T2
($32,638.4 ± $25,348.9 vs $40120 ± $19,004; p<0.0001 and $41,678 ± $30573 vs
$57,610 ± $41,197; p<0.0001). In T2, robotic procedures were more likely to be
performed at urban teaching hospitals (58.5% vs 61.8%; p=0.002) and, regionally, the
robot was more commonly used in the South (33.6% vs 42.53%; p<0.0001).
Using multivariate regression, when controlling for age, hospital geographic region,
hospital ownership type, teaching status, elective versus non-elective, and zip code
median income, robotic repair remained an independent predictor of increased charges
($54, 684.3± $930.3 vs $41,654.6 ± $396.0; p<0.0001).
Conclusion: Utilization of RAS has rapidly increased. Increased robot utilization in
non-elective admissions has not worsened outcomes. Compared to its laparoscopic
counterpart, robotic antireflux surgery has significant increased cost.

QS 55. TEN-YEAR TRENDS IN TRAUMATIC INJURY MECHANISMS AND
OUTCOMES; A TRAUMA REGISTRY ANALYSIS
Z Khorgami MD, W Fleischer MD, YA Chen MD, N Mushtaq PhD MBBS MPH, MS
Charles MD, CA Howard MD
Tulsa, OK
Background: Trauma is the leading cause of death among persons aged 1-44 years in
the United States. In addition to mortality and disability, trauma can place a significant
financial and social burden on individuals and families. The Oklahoma Trauma
Registry collects data regarding injured patients from all state-licensed acute care
hospitals. This study investigates trends and outcomes of trauma in Oklahoma using a
retrospective review of the Oklahoma Trauma Registry.
Method: Patient characteristics, mechanisms of injury, and outcomes of trauma were
analyzed from Oklahoma Trauma Registry data from 2005-2014, excluding 379
patients (0.3%) without recorded etiologies. The study population consisted of patients
with a trauma diagnosis (ICD-9 800.00-959.9) and with major severity (Abbreviated
Injury Scale severity value≥ 3, Injury Severity Score≥ 9, TRISS or Burn Survival
Probability < 0.90, or death). One of the following was also required: 1) length of
hospital stay≥ 48 hours; 2) dead on arrival or death in the hospital, 3) hospital transfer,
4) ICU admission, or 5) surgery on the head, chest, abdomen, or vascular system.
Exclusion criteria included isolated orthopedic injury to the extremities due to same
level falls, overexertion injuries, electrocution and other miscellaneous injuries.
Results: 107,549 patients were analyzed (62.6% male, mean age 43.3±26.1 years, and
mean injury severity scale 10.6±9.2). Prevalence of falls increased during the study
period with an annual percent change (APC) of 4.0 (CI 95%: 3.1 to 4.9) while motor
vehicle collisions decreased with an APC of -3.9 (CI: -5.1 to -2.8). The ICU admission
rate over the study period was 26.2% with the highest rates in gunshot wounds (36.6%)
and motor vehicle accidents (37.2%) (p<0.001). Patients with falls had the lowest rate of
discharge to home (59.4%) in contrast to 72.8% of the entire cohort (p<0.001). Mean
overall mortality rate was 5.4% with the highest rates in gunshot wounds (19.3%) and
auto-pedestrian accidents (11%). The number of overall deaths per year remained stable
except in falls which increased proportionate to the increase of fall frequency. The
mortality of patients with falls was 4.2% and intracranial bleeding was present in 60%.
Conclusion: Falls are significantly increasing as a mechanism of trauma admissions
and trauma-related deaths in the state of Oklahoma. Analysis of state-based trauma
registries can identify trends in the etiologies and other characteristics of injuries and
may indicate a reference point to prioritize action plans by trauma centers to care for
injured patients.

QS 56. OPERATING ROOM FIRES REPORTED TO THE FOOD AND DRUG
ADMINISTRATION
DM Overbey MD, SA Hilton MD, TS Jones MS, BC Chapman MD, TN Robinson
MD, EL Jones MD
Aurora, CO
Background: Operating room fires cause catastrophic surgical complications. More
than 600 operating room fires occur in the United States annually. Fires occur when all
three elements of the fire triangle are present, and are therefore preventable if surgeons
can understand what elements of the fire triangle are most commonly associated with
surgical fires. There is a gap in knowledge in the surgical literature given no large
series focused on operating room fires exists. Our PURPOSES were: (1) to describe
the elements of the fire triangle common in operating room fires, and (2) to quantify
injuries created by operating room fires.
Method: The FDA’s Manufacturer and User Facility Device Experience (MAUDE)
database was searched for reports involving a fire related to a device or product between
2006 and 2016. Three criteria were used for inclusion: location inside an operating
or procedure room, involvement of a patient, and inclusion the words “fire”, “flame”,
“explosion”, or “smoke”. Reports were stratified by elements in the fire triangle: ignition
source, oxygen, and fuel source. Patient injury was quantified and serious patient injury
was defined when a patient required an additional invasive procedure to treat the injury
due to the fire.
Results: 604 reports were individually examined, of which 205 met all inclusion
criteria (34%). Reports increased in frequency from 10 reports in 2006 to 44 reports
in 2015. Patient injuries occurred in 56% of cases (n=115). Of all injuries, serious
injuries requiring further invasive procedure occurred in 34% (n=39). Surgeon injuries
occurred in 2% (n=4).
Examining the elements of the fire triangle involved with operating room fires:
Ignition source: Ignition sources were most commonly electrosurgical devices for 89%
(n=183; p<0.001 vs composite of all other ignition sources). Specific ignition sources
included monopolar (n=134, 65.4%), lasers (n=19, 9.3%), bipolar (n=16, 7.8%), and
peripheral equipment (n=16, 7.8%).
Oxygen: Head and neck operations in close proximity to increased oxygen composed
the majority of reports (n=68, 33.2%)(p<0.001 vs composite of all locations). Increased
oxygen concentrations were explicitly stated to be the cause of the fire in 34% (n=70).
Fuel sources: Fuel sources included equipment or devices (n=80, 39.0%), patient tissue
(n=60, 29.3%), drapes (n=27, 13.2%), prep solution (n=15, 7.3%), sponges (n=15, 7.3%),
and surgeon tissue or gloves (n=8, 3.9%).
Conclusion: Fires cause serious injury in one in three events. In the context of the
fire triangle, operating room fires most commonly occur due to electrosurgery as the
ignition source, increased oxygen as the oxidizer and additional equipment material
as the fuel source. These practical findings can aid surgeons to prevent fires because
removing one of the elements of the fire triangle will prevent the occurrence of an
operating room fire. This report represents the largest collection of operating room fire
reports to date.

QS 57. PREPERITONEAL PELVIC PACKING IS EFFECTIVE FOR
HEMORRHAGE CONTROL WITH OPEN PELVIC FRACTURES

Campion,
Mitchel J. Cohen, Ryan A. Lawless, Fredric M. Pieracci
Denver, CO
Background: Open pelvic fractures are historically reported as devastating injuries
with a mortality rate between 30-60%. Preperitoneal pelvic packing (PPP) has been
suggested to be ineffective for hemorrhage control in open pelvic fractures. With a
developing experience in PPP for hemodynamically unstable patients with pelvic
fracture related hemorrhage, we questioned this belief. The purpose of this study was
to evaluate the role of PPP in patients with open fractures. We hypothesize that PPP is
effective at hemorrhage control for pelvic facture bleeding in patients with open pelvic
fractures and reduces mortality.
Method: Patients undergoing PPP for pelvic fracture hemorrhage from 2005-2015 were
studied prospectively. We identified a subgroup of patients with open pelvic fractures,
defined as direct communication of the bony injury with overlying soft tissue, vagina,
or rectum. Indication for PPP is persistent systolic blood pressure (SBP) <90 mmHg
in the initial resuscitation period despite the transfusion of 2 units of packed RBCs. In
addition to PPP, all patients also had external fixation of their fractures performed.
Results: During the 10-year study, 126 patients underwent PPP; 14 (11%) patients
sustained an open pelvic fracture; their mean age was 35  14 years and ISS 46 
12. The lowest mean emergency department SBP was 75 mmHg, highest heart rate
was 119, and worst base deficit was 12. Median time to operation was 44 minutes.
Median RBC transfusions prior to SICU admission compared to the 24 postoperative
hours were 12 versus 3 units (p<0.05). After PPP, 1 (7%) patient underwent
angioembolization with a documented arterial blush.
Fracture classification included APC-III (5), APC-II (4), LC-III (3), and LC-II (2)
patterns. The open fracture classification included perineal/sacral wounds (8) and
vaginal lacerations (4). PPP controlled pelvic hemorrhage; there was one death in the
study population which was due to a traumatic brain injury. The overall mortality rate
was 7%.
Conclusion: PPP is effective for hemorrhage control in patients with open pelvic
fractures. Mortality in this unstable pelvic fracture group was 7% which is lower than
previous reports. PPP should be used in a standardized protocol for hemodynamically
unstable patient with pelvic fractures regardless of associated perineal injuries.

RESUSCITATIVE ENDOVASCULAR BALLOON OCCLUSION OF THE
AORTA WITH CLOSED CHEST COMPRESSION (REBOACCC) IS HIGHER
COMPARED TO OPEN CHEST CARDIAC MASSAGE WITH AORTIC
CROSS-CLAMP (OCCMACC)
M Brenner MD MS, WA Teeter MD MS, M Bradley MD, A Romagnoli MD MS, P
Hu PhD, S Yang, T Scalea MD, D Stein MD MPH
Baltimore, MD
Background: EtCO2 is a marker of quality of cardiopulmonary resuscitation
(CPR). The purpose of this study is to compare OCCMACC versus REBOACCC on
resuscitation outcomes.
Method: Between Feb 2013 and September 2016, patients who received REBOACCC
for traumatic arrest were compared to patients receiving OCCMACC for the same
indication. Physiologic data was calculated from continuous vital sign monitoring,
and timing metrics were recorded by time-stamped videography. Final measurements
were collected at 15mins or death, whichever occurred first. Total cardiac compression
fraction represents the duration of cardiac compression relative to duration of
resuscitation in a patient in arrest.
Results: 45 patients were enrolled; 21 REBOACCC and 24 OCCMACC. 89% were
male with mean age of 37±13 years. 22 patients suffered penetrating trauma in the
OCCMACC group compared to 7 of the REBOACCC group (p=0.0001). Mean
ISS did not differ between OCCMACC (40.9±14.6) and REBOACCC (35.7±15.6),
p=0.25. During the period of CPR prior to aortic occlusion, there was no significant
difference in initial EtCO2 values between groups, but mean, median, peak, and final
EtCO2 values were lower in OCCMACC (p < 0.013). During the periods of CPR after
aortic occlusion, the initial, mean, median, and final EtCO2 values were higher with
REBOACCC than OCCMACC (p=0.006, 0.014, 0.013, 0.04). The rate of return of
spontaneous circulation (ROSC) was higher in REBOACCC (57%) vs OCCMACC
(24%) (p = 0.037), and REBOA/CCC patients survived to operative intervention
more frequently (p=0.09). REBOACCC patients had greater total cardiac compression
fraction prior to AO than OCCMACC (85.3±12.7% vs. 35.2±18.6% p<0.0001), as well
as after AO (88.3±7.8% vs. 71.9±24.4%, p=0.0052). In-hospital mortality was 93%
(100% OCCMACC vs. 86% REBOACCC, p=0.9). Location of death differed between
groups (p=0.03); all OCCMACC patients died in resuscitation area or operating room,
while 3 REBOACCC patients died in the ICU, 2 were discharged from the hospital,
and 1 discharge is currently pending.
Conclusion: REBOACCC patients have higher EtCO2 levels before and after
aortic occlusion compared to patients who receive OCCMACC, suggesting that
REBOACCC may offer improved resuscitation as measured by EtCO2. REBOACCC
patients also receive a greater duration of cardiac compression, have a higher rate of
ROSC, and survive more often beyond the resuscitation area compared to OCCMACC
patients. Further research is needed to determine whether these findings can translate
into improved clinical outcomes.

QS 59. PATHOLOGIC FINDINGS OF THE GALLBLADDER IN PATIENTS
UNDERGOING SURGERY FOR BILIARY DYSKINESIA
H AHMED MD, D HWANG, S DISSANAIKE MD
Lubbock, TX
Background: Cholecystectomies have been shown to be effective for patients with
symptomatic cholelithiasis, but have shown variable success in patients with acalculous
gallbladders. Some studies attempted to correlate factors such as gallbladder ejection
fraction by hepatobiliary iminodiacetic acid (HIDA) scans as indicators of pathology
in cholecystectomy patients, to our knowledge there are only few studies that have
compared the direct pathologic characteristics such as cholecystitis and cholesterolosis
of acalculous gallbladders with biliary dyskinesia.
Method: In this study, we reviewed the gallbladder pathology reports of 100 patients
from 2005-2016 who underwent cholecystectomies for acalculous biliary dyskinesia at
our institution. We also documented the results of preoperative diagnostic tests, and
general demographic information.
Results: Patients had a mean age of 32 (9,85) and were predominantly female (81%)
(Table 1). The majority of our patients reported as white or Hispanic (50% and 43%
respectively). All patients had abnormal HIDA scan/Ejection fraction (EF<35%). The
pathology reports were normal for 35% of patients, while 28% reported cholecystitis.
37% of patients also reported other pathology such as mucosal hyperplasia,
cholesterosis, and sinuses/polyps. In females, the average age of cholecystitis affected
individuals was younger than all other pathologies. Although not a large enough
difference to be statistically significant, there could be a correlation between age and
cholecystitis.

Conclusion: The finding of other pathologies suggest that the preoperative diagnosis of
biliary dyskinesia may not be the only cause of symptoms for patients and could be due
to other pathologies of the gallbladder in two thirds of patients that may also be related
to biliary dyskinesia. A majority of patients undergoing surgery for Biliary Dyskinesia
show some pathologic abnormality, the relative significance of these findings need to be
further explored.

QS 58. ROUGH DAY AT THE BEACH: EPIDEMIOLOGY AND CLINICAL
PRESENTATION OF SPINAL CORD INJURY IN HAWAII
S Steinemann MD, W Biffl MD, J Cheng BA, D Galanis PhD
Honolulu, HI
Background: Spinal cord injuries (SCI) result from a broad spectrum of blunt trauma
mechanisms, predominantly falls and motor vehicle crashes. However in our state,
ocean related activities are a common cause of SCI. We propose that ocean related SCI
represent a unique subset of SCI in terms of geographic and demographic clustering
and pattern of injury.
Method: Data from our state trauma registry, capturing trauma team activations and
admissions at 7 hospitals, were reviewed. SCI were identified by ICD9-CM diagnosis
codes in the 806.0-806.9 and 952.0-952.9 series. Statistics were adjusted for patients
who were transferred between hospitals.
Results: A total of 630 SCI cases from 2009-2013 were identified. The most frequent
causes were ocean related activities (209 patients, 33% of the total), followed by falls
(25%), and motor vehicle crashes (22%). The incidence of ocean related SCI nearly
doubled over the 4 years, from 27 to 52 cases annually. Among the 209 patients injured
in ocean activities, most (85%) were injured by “wave forced impact” (WFI) while
surfing (14), body boarding (46), body surfing (54) or being “tossed by a wave” (63).
There were also 31 injuries from dives into the ocean. 84% of patients injured by WFI
were out-of-state visitors, as well as 45% of those injured from dives. 89% of ocean
related SCI were isolated to the cervical spine. Only 27% had a fracture in addition
to SCI. A complete cord lesion was suffered by 23% of those injured by diving and
10% injured by WFI. The locations of ocean related SCI were dispersed statewide; the
4 beaches with the highest numbers were all on different islands. However, 55% of
injuries were clustered on 10 beaches which host a minority of beachgoers. 2 of these
beaches, facing northwest, had most incidents during the winter.
Conclusion: Ocean related activities are the leading cause of SCI in our state. These are
typically isolated cervical injuries, most without an associated fracture. Ocean related
SCI, particularly those caused by WFI, disproportionately affects out-of-state visitors at
distinct high risk beaches. These data may inform the development of targeted injury
prevention efforts.

QS 60. SURGICAL EVACUATION OF ACUTE SUBDURAL HEMATOMA IN
OCTOGENARIANS: A TEN YEAR EXPERIENCE FROM A SINGLE TRAUMA
CENTER
MJ McGinity MD, JS Rodriguez PhD, JE Michalek PhD, JR Floyd MD
San Antonio, TX
Background: Elderly patients presenting with an acute subdural hematoma (aSDH)
have historically had unfavorable outcomes. Traditionally, elderly has been defined as
greater than sixty five years of age when discussing traumatic brain injury. However,
an aging population has lead to an increase in low mechanism induced traumatic brain
injury in the very elderly(>80). Prior series have discussed surgical outcomes of subdural
hematoma evacuation in patients >80, but have not separated chronic subdural
hematoma(cSDH) from aSDH which act markedly different. We sought to determine
surgical outcome of acute subdural hematoma evacuation via craniotomy for patients
>80 years old.
Method: We retrospectively reviewed all charts of patients from 2005 through 2015
who were 80 years of age or older and underwent craniotomy or craniotomy for surgical
evacuation of aSDH. Metrics collected were as follows: Glascow Outcome Score
(GOS), age, mechanism of injury, procedure used for clot evacuation (craniotomy vs.
craniectomy), pre-hospital use of anticoagulants or antiplatelets, pupillary reactivity,
thickness of aSDH, amount of midline shift, initial Glascow Coma Score (GCS),
presence of neurological decline prior to surgery, best post operative GCS, length
of hospital stay, # of ICU days, # and type of comorbidities, # of major in-house
complications, # of total invasive procedures performed, requirement of percutaneous
endoscopic gastrostomy (PEG) tube placement, requirement for tracheostomy, and
initial disposition from hospital. Specific metrics were compared against the primary
outcome measure, Glascow Outcome Score. GOS of 4-5 was deemed a good outcome
and a GOS of 1-3 was deemed to be a poor outcome.
Results: Thirty-four patients met inclusion criteria, with a mean age of 84 years (range
80-91) and an overall mean follow up of 65 days. Patients with good outcome (GOS
4-5) had mean follow up of 112 days (range 25-245). Six patients had good outcome at
last follow up (GOS 4-5) and 27 patients had poor outcome (GOS 1-3). One patient’s
medical record was incomplete and did not indicate outcome. The majority of injuries
resulted from falls (31 falls, 2 motor vehicle accidents, 1 assault). The mean number of
days spent in the ICU was 9.9 days (median 9 days, IQR 11). The mean length of stay
in the hospital was 13.2 days (median 14, IQR 13). The pre-injury use of antiplatelet,
anticoagulant or combinations of the above did not statistically correlate with outcome.
It was noted, however, that all patients taking Plavix (5 patients) had a poor outcome.
Six patients were operated on with at least one dilated and non-reactive pupil with
1 of these patients surviving and recovering to normal. Although the thickness of
the subdural hematoma’s effect on outcome did not reach statistical significance, the
difference appears to be clinically relevant [(good outcome: mean 16.6mm, median
17mm, IQR 7) vs (poor outcome: mean 21.1mm, median 20mm, IQR 8.5), p=0.17,

Figure 1]. In addition, the amount of midline shift similarly did not reach statistical
significance, but also appears to be clinically relevant [(good outcome: mean 8.75mm,
median 10mm, IQR 6.5) vs. (poor outcome: mean 14mm, median 14, IQR10), p=0.07,
Figure 1].
The presenting GCS trended towards being higher in patients who had good outcome
compared to poor outcome (good: mean 13.1, median 14.5, IQR 2.5; poor: mean 9.6,
median 10, IQR 8). This did not reach statistical significance but also appears to be
clinically relevant (p=0.06). Patients with a higher in-hospital post-operative GCS had
much better overall outcome than patients who left the hospital with lower GCS which
was highly statistically significant (good: mean 14.5, median 14.5; poor: mean 8.4,
median 9, p=0.001). Thirteen of the included patients arrived to the hospital with GCS
scores of 14 or 15 and were initially managed conservatively. However, all but 1 of these
patients had a decline in neurologic examination, prompting surgical intervention and
inclusion into the study. Patients with an in-hospital decline in neurological exam prior
to operative intervention fared slightly better than patients who presented with an exam
necessitating emergent surgical intervention, but this was not statistically significant
(p=0.66).
No individual major comorbidity was statistically predictive of outcome (renal disease,
cardiac disease, hypertension, diabetes mellitus, pulmonary disease, prior cerebral
vascular accident, any other prior neurological disease). Mean overall number of
comorbidities was 3.3 (median 3, IQR 1). Patients with poor outcomes had mean
number of comorbidities of 3.4 (median 3, IQR1) compared to good outcomes of 3
(median 3, IQR 0). Every patient in the study had at-least one comorbidity except one,
where no past medical history was available. Total number of in-house complications
trended towards being higher for patients with good outcomes (mean 3, median 3, IQR
1.5) compared to poor outcomes (mean 2.2, median 2.5, IQR 2), presumably because
they were alive to have complications arise. This did not reach statistical significance,
p=0.26, however. The most common complications were pneumonia, deep venous
thrombosis or pulmonary embolism, seizures, new onset cardiac arrhythmia, and
urinary tract infection. Mean overall number of invasive procedures performed was
6 for the entire population (median 6, IQR 2). There was no statistically significant
difference between number of procedure performed on patients with good outcome
(mean 5.33, median 4.5 IQR 2.5) compared to poor outcome (mean 6.1, median 6,
IQR2), p=0.19. No patient requiring gastrostomy placement (n=3) recovered to have a
good outcome. One patient requiring tracheostomy (n=5) recovered to having a good
outcome.
Conclusion: Although very frequently associated with poor prognosis, the evidence
presented here does not indicate acute subdural hematoma in the very elderly to be a
universally fatal or debilitating disease. Surgical evacuation should be considered in
these patients.

QS 62. HYPERTRIGLYCERIDEMIA INDUCED PANCREATITIS: DOES
PLASMAPHERESIS REALLY MAKE A DIFFERENCE?
LB O’Meara CRNP, BC Eaton CRNP, AM Pasley DO, ES Wise MD, LA Harmon
MD, AV Herrera MS, JD Pasley DO, JJ Diaz MD, RB Tesoriero MD
Baltimore, MD
Background: Hypertriglyceridemia (HTG) accounts for up to 10% of all cases of
acute pancreatitis (AP). Optimal treatment of HGT-AP is not well characterized.
Plasmapheresis (PLX) rapidly reduces plasma triglyceride concentration and may
ameliorate cytokine-mediated inflammation. Its efficacy as an adjunctive therapy to
reduce disease severity in HTG-AP has thus far only been suggested in case reports and
small case series. We sought to review our institutional experience with PTX in HTGAP to evaluate its effect on outcomes compared to conventional therapy.
Method: A retrospective review of consecutive adult patients who presented with
HTG-AP to a single quaternary care center from 2010-2015 was performed. Hospital
records were reviewed for demographics, comorbidities, laboratory values, computed
tomography (CT) severity of AP, mortality, intensive care unit (ICU) and hospital
length of stay (LOS), use of mechanical ventilation, and 6 week readmission rate.
Patients were stratified based on the presence or absence of PLX treatment at any point
during their hospital stay. The decision to initiate PLX was at the discretion of the
medical team. Statistical comparisons between PLX cohorts were conducted using
Fisher’s exact test or the Mann-Whitney U Test, as appropriate. The criterion P<.05 was
used to denote statistical significance.
Results: Eighteen patients who presented with HTG-AP were identified, eight of
whom received plasmapheresis. The two cohorts were well-matched with respect to
demographics, admission triglyceride and lipase levels, and CT severity scores. There
were no significant differences in mortality, hospital LOS, ICU LOS, mechanical
ventilation, and readmission rates evaluated (Table 1). Thirteen patients required
admission to the ICU, 7 of whom received PLX. Within the ICU subgroup, there was
no difference in overall LOS (20 [17-29] days vs. 20 [10-26]; P = .58), ICU LOS (13
[12-20] days vs. 10 [5-15] days; P = .37) nor days on the ventilator (10 [5-10] days vs. 12
[9-13] days; P = .57), when comparing those who received PLX with those treated with
conventional therapy.
Conclusion: We report one of the largest North American series comparing patients
with HTG-AP who received plasmapheresis to those treated with conventional therapy.
Though limited by a restricted sample size, this comparison of two well-matched
groups of patients did not show a benefit in LOS, requirement for ventilator support, or
patient mortality in those who were treated with PLX. Considering the added expense
and potential morbidity from PLX further well designed studies are needed to more
thoroughly understand its role in the management of HTG-AP.

QS 63. THE GREY’S ANATOMY EFFECT: TELEVISION PORTRAYAL OF
TRAUMA PATIENTS MAY CULTIVATE UNREALISTIC PATIENT AND
FAMILY EXPECTATIONS FOLLOWING INJURY
RO Serrone MD, JA Weinberg MD, PW Goslar PhD, EP Wilkinson PA, JL
Dameworth MD, S Hosler, SR Petersen MD
Phoenix, AZ
Background: Prior research has demonstrated that public perception of healthcare is
influenced by medical television dramas, and representations of medical interventions
are relatively inaccurate. This is salient for trauma patients and families, given that
exposure to genuine trauma patient experience is sparse. It is our perception that
portrayal of hospitalization following acute injury is inaccurate. The purpose of this
study was to compare outcomes and course of hospitalization following major trauma
on television dramas versus reality.
Method: Providers from an ACS level-1 Trauma Center screened 269 episodes of
seasons 1-12 of the television series Grey’s Anatomy, the most popular fictional medical
drama airing from 2005 to present. A TV registry was constructed by collecting
demographics, injury characteristics, procedures, length of stay, and discharge
disposition for each fictional trauma patient. A certified trauma registrar calculated
ISS. Comparison data were obtained from a sample selected from the 2012 National
Trauma Databank (NTDB) to reflect a level-1 trauma center in a similar geographic
region as the setting for Grey’s Anatomy.
Results: 290 patients comprised the TV registry versus 4812 patients from NTDB
sample. Demographically, TV patients were younger (mean age 34vs.41,p<0.0001),
more likely female (40%vs.30%, p<0.0001), and had higher ISS (mean
14vs.12,p=0.013). Mortality following injury was significantly higher on TV compared
with reality (22%vs.7%,p <0.0001), with most TV patients dying within the first 24
hours. Most TV patients went straight from ED to OR (71%), compared with 25% in
NTDB (p<0.0001). Among TV survivors, hospital length of stay appeared to be less
than one week for most patients followed by discharge home (92%), whereas 30% of
the NTDB cohort had a length of stay beyond 1 week and 22% were discharged to
long-term care.
Conclusion: On television, trauma patients typically go straight from ED to OR, and
survivors experience a short hospital course followed by return to home, whereas in
reality, most patients do not go immediately to OR, and a significant portion have a
prolonged length of stay followed by discharge to long-term care. TV portrayal of rapid
functional recovery following major injury may cultivate false expectations among
patients and families who are regular television viewers.

QS 64. ADRENALECTOMY IN OCTOGENARIANS: ASSESSMENT OF
OUTCOMES
SM Sims MD, KM Coakley DO, T Prasad MA, VA Augenstein MD, KW Kercher
MD, R Sing DO, BT Heniford MD, PD Colavita MD
Charlotte, NC
Background: The increasing life span of Americans and rising prevalence of advanced
imaging studies have led to a greater incidence of elderly patients presenting with
adrenal lesions. The purpose of this study is to evaluate outcomes after adrenalectomy
in patients age 80 and over as compared with younger patients.
Method: The National Surgery Quality Improvement Program database was utilized
to investigate patients with CPT codes associated with laparoscopic and open
adrenalectomies from 2005-2014. Patient demographics, mortality, hospital length of
stay, discharge disposition and complication rates were compared in octogenarians and
in patients ages 50-79.
Results: 4785 patients age 50 or older in the United States who underwent
adrenalectomy were identified. There were 190 (3.97%) age 80 and above and 4595
(96.03%) in the younger group, utilizing laparoscopic technique in 3330 (69.6%) and
an open approach in 1455 (30.4%). 4231 (88.4%) were performed by general surgeons
and 515 (10.8%) by urologic surgeons. More patients in the older group underwent
an open adrenalectomy (41.6% v. 30.0% p=0.0006). Rates of diabetes, COPD, CHF,
history of an MI or CVA, and chronic renal failure were similar between the two
groups. There was a greater incidence of current tobacco use in the younger group
(10.5 v. 23%). There were similar rates of wound complications, DVTs, pulmonary
embolism, acute MI, sepsis, and transfusion requirement between the two groups, but
an increased rate of prolonged ventilator use for >48 hours (5.79 v. 2.46% p= 0.016),
progression to renal insufficiency (2.63 v. 0.44% p= 0.003), and stroke with neurologic
deficit (1.58 v. 0.22% p= 0.01) in the older group. The hospital length of stay (LOS)
was significantly higher in the patients age 80 and above (9.36 ± 11.85 v. 4.67 ± 6.92
p=0.0001. Controlling for confounding variables, with multivariate linear regression,
age >80 was independently associated with longer LOS (10.3 ± 0.81 v. 6.21 ±0.19
p<.0001). The surgical approach also independently impacted LOS in this analysis
(laparoscopic 5.06 ± 0.43 v. open 11.5 ± 0.49 p<0.0001). The overall 30-day mortality
rates were similar (2.11 v. 1.04%, P=0.15).
Conclusion: Although advanced age can be associated with increased LOS and rates
of need for prolonged intubation and cerebrovascular accidents, there is not significant
difference in 30-day mortality or most complications following adrenalectomy.
The increased LOS was still found to be higher in the older population, even when
controlled for the greater proportion performed with an open approach in this
group, signifying age as well as surgical approach independently impact hospital
stay postoperatively. As such, in appropriately selected patients, adrenalectomy can
be considered in patients age 80 and older without prohibitively increased risks as
compared with their younger counterparts.

QS 65. CHANGING PRACTICES: THE ADDITION OF A NOVEL SURGICAL
APPROACH TO GYNECOMASTIA
DL Wyrick MD, M Roberts MD. ZT Young MD, AT Mancino MD
Little Rock, AR
Background: Gynecomastia can be a significant impediment to quality of life for
men who suffer from this affliction. Numerous techniques have been described in
the literature ranging from minimally invasive options such as liposuction to incision
based reductions. The standard for the general surgeons at our institution has been
subcutaneous mastectomy through a circumareolar incision, which often proved
inadequate for patients with grade II or III gynecomastia. In November 2013 we
adopted a new technique, the “double donut”, that offers the post-operative appearance
of a limited incision, with the additional benefits of mastopexy, skin reduction, and
mastectomy through an enlarged incision which is not superficially evident at the
completion of the procedure.
Method: We reviewed our surgical database for all cases performed for gynecomastia
in the period from May 2005 to August 2016. Basic demographic information,
diagnostic modality, symptoms, indication for procedure, operation performed, and
final pathology were collected and analyzed.
Results: There were 70 mastectomies performed on 52 subjects. All subjects were
male; 14 were African American and 38 were Caucasian. The average age was 47 (2373) years old. The majority of the patients were evaluated with mammogram and/or
ultrasound. All but one patient presented with pain as their chief complaint. There were
41 mastectomies done prior to initiation of this technique and 29 were performed after.
The total volume of breast tissue excised via the previous technique was 127.1cm3, this
increased to 157.2cm3with the new technique. No necrosis of the NAC was seen and
no wound infections resulted in complication. Cosmetic satisfaction was seen in 98
percent of patients.
Conclusion: The “double donut” technique is particularly useful for males with
grades II or III gynecomastia. It provides good wound results, with acceptable patient
satisfaction and cosmetic outcomes. Although initially developed for patients with
higher grade gynecomastia, the improved visibility and increased patient satisfaction
allowed this to become the preferred technique at our institution.

MELANOMA
BC Chapman MD, A Gleisner A MD, PHD, DM Overbey MD, C Stewart MD, JJ
Kwak MD, C Gadjos MD, NW Pearlman MD, MD McCarter MD, N Kounalakis
MD
Aurora, CO
Background: Head and neck (H&N) melanoma accounts for 15-30% of primary
melanomas. The objective of this study is to identify and assess novel prognostic
features associated with cutaneous melanomas of the head and neck.
Method: Retrospective review of patients undergoing sentinel lymph node biopsy
for cutaneous melanoma of the H&N (1998-2016). Using Cox proportional hazards
model, variables associated with disease free survival (DFS) and overall survival (OS)
on univariate analysis with a p<0.1 were analyzed on multivariate analysis.
Results: Among 256 patients identified, median age was 57 years (range 14-91)
years, 196 (77%) were male, and median tumor depth was 1.6 mm (range 0.2512.0). The majority of melanomas (65%) were first noticed by patients although 9%
were diagnosed by a hairdresser. Cryotherapy was performed on the melanoma site
prior to diagnosis in 9% of patients. Transection at the base of the diagnostic biopsy
occurred in 96 (38%) patients, yet 74 (77%) had no residual melanoma on the wide
local excision (WLE). In total, residual melanoma was found on WLE in 108 (42.2%)
patients. A positive SLN was identified in 40 (16%) patients. At a median follow-up
time of 2.3 years, 40 (16%) patients had a loco-regional recurrence and 43 (17%) had
distant disease. Gender, diagnostician, prior cryotherapy, type of melanoma, mitosis,
and a transected biopsy were not associated with DFS or OS. On multivariate analysis,
factors associated with both a worse DFS and OS included increasing age and tumor
depth, scalp melanoma, ulceration, and a positive SLN. Although residual melanoma
on the wide local excision was associated with a poorer DFS, it was not found to be
significant for OS.
Conclusion: Increasing age and tumor depth, scalp melanoma, ulceration, and a
positive SLN are poor prognostic features in H&N melanoma. Three quarters of
patients with a positive deep margin on diagnostic biopsy had no residual melanoma
at WLE. Independent of other prognostic variables, residual melanoma was associated
with a worse DFS.

QS 67. ASSESSING EMERGENCY EXPLORATORY LAPAROTOMIES IN
PATIENTS WITH ADVANCED MALIGNANCIES
EB Pillado BS, ZW Ashman MD, MP O’Leary MD, DY Kim MD, DS Plurad MD
Torrance, CA
Background: Advanced cancer often requires emergent surgical interventions
despite high rates of complication and death. To quantify in-hospital mortality, 30day mortality, and overall outcomes in patients with advanced malignancies who
underwent emergency exploratory laparotomy.
Method: We reviewed our institutional experience between 2008 and 2016 of acute
care surgery consultations among patients with advanced malignancy that underwent
emergency exploratory laparotomy.
Results: Out of 52 patients, 26 (50%) were male. Twelve (23.1%) patients were
newly diagnosed with cancer on exploratory laparotomy while 4 (7.7%) patients were
upstaged to Stage IV. Common primary malignancies were colorectal (n=26, 50%),
prostate (n=4, 7.8%), and gastric (n=4, 7.8%). Remaining diagnoses included other
intra-abdominal malignancies and lung cancer. Indications for surgery included
obstruction (n=25, 56.8%), perforation (n=11, 25%), or a combination (n=8, 18.2%).
In-hospital mortality was 13.5% (n=7), post-discharge thirty-day mortality was 7.7%
(n=4), and 32.7% (n=17) had post-operative complications. Seventy-one percent were
discharged home, 3.9% were discharged to hospice, and 5.8% were discharged to
home hospice. Overall ICU stay was significantly longer in those who died within 30
days (18.4±7.1 versus 1.9±0.78, p<0.01). Two patients had preadmission DNR orders.
Thirteen patients (25.5%) had DNR orders placed during the hospitalization, 8 of
which expired within 30 days (p<0.01).
Conclusion: Selective use of surgical intervention in patients with advanced
malignancy can result in acceptable short term outcomes including discharge home.
Additional efforts should be directed at increasing the rate of advanced directives in
this population with limited life expectancy.

QS 69. 4- HOUR POST-OPERATIVE PTH LEVEL PREDICTS
HYPOCALCEMIA AFTER THYROIDECTOMY IN CHILDREN
LB Hsieh MD, SW Bruch MD
Ann Arbor, MI
Background: Hypocalcemia is a common complication of total thyroidectomy
in pediatric patients, reported to be anywhere from 30-40%. Four hour postoperative PTH monitoring has been shown to be predictive of the need for calcium
supplementation in the adult thyroidectomy population. We evaluated the role of
the 4 hr post-operative PTH level in determining calcium supplementation after
thyroidectomy in the pediatric patient.
Method: This is a retrospective review of pediatric patients undergoing total
thyroidectomy by a single pediatric surgeon from July 2011 to June 2016. Intact
PTH obtained four hours post-operatively was used to determine the use for calcium
supplementation for patients beginning in November 2014 onward. Total calcium
levels were monitored concurrently with intact PTH levels. Each patient had at least
one post-operative visit 2-4 weeks after surgery to assess healing as well as development
of hypocalcemia.
Results: From July, 2011 to June 2016, there was a total of 53 thyroid procedures,
of which 34 are total thyroidectomies. Prior to November 2014, all pediatric total
thyroidectomies received calcium supplementations per our institutional protocol,
with 30% (6/20) post-operative hypocalcemia based on ionized calcium levels. From
November 2014 to June 2016, there was a total of 14 pediatric patients with total
thyroidectomies. 4/14 (29%) had low 4-hour post-operative PTH levels. 3 out of the 4
patients with low 4-hour post-operative PTH levels had corresponding total calcium
levels less than 8, with only one patient with symptomatic hypocalcemia. 10 of the 14
patients had normal 4-hour post op PTH levels, with 1/10 having hypocalcemia based
on lab values (Table 1.) A single 4-hr post-operative PTH <10pg/dl has a sensitivity of
75% and specificity of 90% in predicting post-operative hypocalcemia (<8mg/dl), with
a positive and negative predictive value of 75% and 90% respectively (Table 1). Only
one patient developed persistent hypocalcemia.
Conclusion: The 4-hour post-operative PTH level can help determine the need for
calcium supplementation in pediatric patients undergoing total thyroidectomy, thereby
reducing unnecessary calcium supplementation and serial lab draws to monitor for
hypocalcemia.

QS 70. QUICK CAROTID SCAN FOR STROKE PREVENTION
GS Lavenson MD
Bethesda, MD
Background: Over 800,000 seniors have strokes every year that have been unabated
for at least the last 10 years. Strokes result in over 100,000 deaths and 300,000 cases
of disability requiring long term institutionalization annually. Effort to reduce strokes
has been primarily expended at determining which treatment is best for carotid artery
disease (CAD), the leading immediate cause of strokes. However, the reason that
strokes continue is that 80% of carotid strokes are due to silent asymptomatic carotid
stenosis (ACS) and while management is effective, the ACS is not known and the
management cannot be applied preemptively to prevent the strokes. The only means to
reduce strokes is to screen large numbers of seniors for ACS so that it can be managed
before strokes occur and the stroke prevented.
Method: A Quick Carotid Scan (QCS) using image only without use of velocities, hard
copies, history, or counseling can be done in 1-2 minutes and rapidly triage out those
with normal carotids from those with visible lesions, color shift connoting increased
velocity due to stenosis, or those with an indeterminate scan who are referred for a full
duplex examination. The QCS had a sensitivity of 93% in our laboratory and 97% at
NYU compared to only 50% with an audible bruit or presence of risk factures in the
Framingham Risk Scale. The QCS is far different than the long, complicated protocol
of the IAC and avoids many objections of the United States Preventive Services Task
Force.
Results: A large composite screening of 22,000 seniors by the SVS/SVU for which
I was a principal investigator, NYU, Madigan Army Hospital (still screening under
Colonel Charles Andersen), and by those of us in Central California found a nearly
uniform incidence of 7.5% of seniors >60 years of age with a >60-70% carotid stenosis.
So, if at least 5% or our 44 million seniors or 2.2 million have significant ACS, and
with a stroke rate without identificatikon and managemnt at least as high as the 10%
with Best Medical Treatment in the Asymptomatic Carotid Artery Stenosis and
Asymptomatic Carotid Surgical Trial studies. This contrasts to the risk of stroke with
current management of 1-2% or less. Thus there are at least 220,000 strokes annually
in the United States due to ACS or 28% of our 800,000 strokes which pencils out to
prevailing estimates which could be prevented.
Conclusion: A QCS of large numbers of seniors can discover the ACS that causes 80%
of strokes due to CAD allowing excellent low risk preemptive management, potential
prevention of strokes on an epidemiological scale, and cost reduction exceeding 60
billion dollars for the health care system.

QS 72. COMPARATIVE ANALYSIS OF PEDIATRIC NON-POWDER VS
POWDER FIREARM INJURIES
MC Johnson MD, E Scherer MD, L Lilian MD, B Eastridge MD, J Myers MD, S
Nicholson MD, M Price MD, D Jenkins MD, R Stewart MD
San Antonio, TX
Background: Firearm injuries remain a significant public health and safety concern
in the United States. Less appreciated is the role non-powder firearm [NPF] injuries
play, especially in our pediatric population. NPF can be purchased in the toy section of
many stores and national estimates show on average over 10,000 pediatric non-powder
firearm-related injuries are seen in US Emergency rooms each year. However, research
regarding the severity and outcomes related to these injuries in children is limited to
small case series and reports. We sought to characterize pediatric injuries from NPF
versus powder firearms [PF] on a national level in regards to demographics, injury
patterns, and outcomes to better understand the extent of morbidity and mortality in
children with NPF injuries. Although likely associated with a decreased mortality, we
hypothesized non-powder firearm injuries would be associated with high morbidity and
operative need.
Method: The National Trauma Data Bank Research Data Set from 2012-2014 was
utilized for analysis. Pediatric population was defined as ages 1-17, and firearm injuries
were searched using e-codes. NPF was defined as propulsion by spring, air, or CO2
(ie: pellets and bb’s) while PF was defined as propulsion by explosion (ie: handguns,
rifles, etc.). Data included demographics, firearm type, intent, disposition, diagnoses,
procedures, and outcomes. Injuries were categorized by body region and associated
procedures were reviewed. Analyses were performed using t-test for continuous and chisquared for categorical variables.
Results: We identified 1,080 children injured by non-powder firearms and 4,525
children injured by powder firearms. Majority of both NPF and PF injuries involved
males. Average age of NPF injuries was significantly less than PF injuries (10.7 vs.
14.16 years; p- <0.001) with a significant predisposition towards non-Hispanic, whites
(p- <0.0001). Comparative analyses showed a significant proportion of non-powder
firearm injuries were unintentional (82.1% p- <0.0001). The majority of NPF injuries
were orbital (29.17%) followed by cranial (14.07%), thoracic (14.81%), and abdominal
(13.70%) injuries. Emergency department disposition indicated a need for operative
intervention in 23.33% vs 28.46% of NPF and PF injuries, respectively. Mortality was
0.37% and 12.55% for NPF and PF, respectively.
Conclusion: A majority of non-powder firearm injuries are unintentional and occur
in the pre-teen population while requiring operative intervention at a clinically
similar rate to powder firearm injuries. Non-powder firearm injury patterns and their
associated operative rate raise concerns for extensive, long-term morbidity in our young
population. These findings further emphasize the need for a comprehensive approach to
reduce NPF injuries.

QS 73. SHORT AND LONG TERM OUTCOMES OF CHILDREN AND
ADOLESCENTS WITH PAPILLARY THYROID CARCINOMA
B Wallace MD, D Partrick MD, A Kulungowski MD, S Travers MD, D Bensard MD,
R McIntyre Jr MD
Aurora, CO
Background: Over previous decades, significant evolution of care for children
and adolescents with papillary thyroid carcinoma (PTC), including the advent of
ultrasound technologies, the advancement of standardized care to total thyroidectomy,
and the use of radioiodine ablation, has made the assessment of applicable modern
outcomes difficult. Therefore, our group evaluated the short and long term outcomes
of a contemporary cohort of pediatric patients treated for PTC by a multidisciplinary
team.
Method: We performed a retrospective chart review over 77 patients less than 21
years of age diagnosed and surgically treated for PTC at two academic institutions
between 2000 and 2016. Presentation, preoperative workup, surgical procedure, short
term outcomes of wound complications, vocal cord paralysis, hypoparathyroidism and
hypocalcemia; long term outcomes of disease free survival, recurrence rates, need for
further surgeries, follow up, and overall survival were assessed.
Results: Median patient age was 14 years ranging between 3.5 and 20 years of age
(SD 4.5), 72% were female, and all patients presented with a palpable neck mass,
occasionally with additional symptoms such as dysphagia. Overall patient survival rate
was 100% with median 4 years follow up. Only 2 patients did not receive preoperative
imaging to evaluate possible metastases. Regional lymph-node metastases at time of
surgery were identified in 67% of patients, with distant metastases occurring in 8%,
most commonly in the lungs. Consequently, 92% of patients were TNM Stage I at
time of operation. Central lymph-node dissection (LND) was performed in 71%,
additional lateral LND in 41%, bilateral LND in 12%, and lobectomy in 8 patients (all
but one had a negative or indeterminate preoperative FNA), with 5 lobectomy patients
receiving immediate subsequent completion total thyroidectomy following pathology
results. Of all patients, 90% measured a nadir serum calcium that met hypocalcemia
definitions, although only half of these patients became symptomatic (not significant
to type of operation nor presence of incidental parathyroid glands). 8% of patients
had longer than 6 months of treatment for hypocalcemia. The cohort had no wound
complications, no axillary nerve injuries, and no unintentional permanent laryngeal
nerve injuries. 62% of patients received I-131 treatment, and 10% of the children had
a local recurrence in the neck additional to the previously mentioned 8% with distal
metastases by time of operation.
Conclusion: Similar to previous reviews, our data demonstrate an increased incidence
of PTC in females, greater pediatric incidence of lymph-node and distant metastases by
time of diagnosis compared with adult populations, and greater need for repeat surgery
in those receiving less than total thyroidectomy. However, while this pediatric cohort
still showed higher recurrence rates than adults, this contemporary pediatric patient
group highlights recurrence rates significantly lower than in alternate studies.

QS 74. SURGICAL TRAINEE AUTONOMY DURING ARTERIOVENOUS
FISTULA CREATION: IS THERE A COST?
A Korn MD,H Alipour MD; J Zane, K Gray MD; A Shahverdani, MD; A Kaji, MD,
PHD, T Ryan, MD; C deVirgilio MD
Torrance, CA
Background: Background: Upper extremity arteriovenous fistula (AVF) creation for
hemodialysis access is a common vascular procedure performed during general surgical
residency. As such, it may provide an opportunity for resident autonomy. We examined
the effect of level of trainee and teaching assistant (TA) on operative times and the 30day complications.
Method: Methods: At a public teaching hospital, consecutive upper extremity (AVF)
performed by surgical trainees were retrospectively reviewed from a 20 month period.
Procedures were classified into those with one trainee taught by the attending (no
resident teaching assistant), and those with two trainees (a junior resident as primary
surgeon, assisted by a more senior trainee who served as TA, supervised by an attending
surgeon. Primary outcome measures were surgical time and 30 day complications.
Results: Results: 261 total cases were performed in the study period. In 157 (60.1%),
there was no trainee TA, whereas a TA was present in 104 (39.8%) operations. The
postgraduate (PG) level of the TA was as follows: a vascular fellow in 17 cases (PGY6 or 7); in 59, a general surgery chief resident (PGY-5); in 5, a PGY-4, and in 23, a
PGY-3 resident. In the majority of cases (65%) the primary surgeon was a PGY-3.
Presence of a TA was associated with increased operative times (112 vs 97 minutes
Wilcoxon p-value= 0.001) as compared to procedures done without a TA. Within
the group without a TA, the PG year of trainee did not affect surgical time (p= 0.7).
Complication data were available for 249 cases. There were 19 total complications.
Presence of a TA was not associated with increased complications within 30 days of
operation (7.7% vs 7.4% OR 1.05 CI 0.4-2.7 p= 0.91).
Conclusion: Conclusion: The AVF appears to be suited for providing graduated general
surgery resident autonomy. The 30 day complication rates are similar whether or not
a TA is utilized. However, the presence of a TA is associated with significantly longer
operative times. With an increasing emphasis on efficiency in the operating room,
hospitals will need to determine whether lengthier operations for the sake of autonomy
are feasible.

P 1. TYPE OF CERVICAL SPINE FRACTURE AND VASCULAR INJURY
OF THE NECK
Y Ishida MD, VJ Olivas MD
El Paso, TX
Background: Due to advancement in imaging technology, more vertebral or
carotid vascular injuries are detected after trauma. Vertebral and carotid vascular
injuries are serious conditions that could lead to stroke, irreversible neurological
sequelae and mortality. Up to 70% of traumatic vertebral artery injuries have an
associated cervical spine fracture. However, there exists no consensus on when
to obtain radiographic imaging of the neck to evaluate for vascular injury. Our
purpose is to determine which type of cervical spine fracture is more associated
with carotid or vertebral artery injuries and to determine if CT angiography of the
neck is warranted in a patient with an isolated occipital condyle fracture.
Method: This was a retrospective chart review of all carotid and vertebral artery
injuries at UMC of El Paso’s Level I Trauma Center from January 2004 to
December 2014.
Results: We had 54 patients total including 16 blunt carotid artery injury patients
(30%) and 38 blunt vertebral artery injury patients (70%).
The most common mechanism was motor vehicle collision (60%) followed by fall
(15%). The mortality was 18%. Angiography was performed in 42% and 18%
required intervention such as stent placement.
Facet dislocation/subluxation (31%) was the most common type of cervical
fracture associated with cervical arterial injury, followed by C1-3 vertebral body
fracture (25%), and transverse process fracture involving the transverse foramen
(22%). (Figure 1) None of isolated occipital condyle fractures were associated with
a carotid or vertebral artery injury. One patient with a transverse process fracture
not involving the transverse foramen had a vertebral artery injury (2%).
Comparing the number of carotid and vertebral artery injury in each type of
fracture, C1-3 vertebral body fracture and facet sublaxation/dislocation were both
more associated with vertebral artery injury versus carotid artery injury. (93% vs
7%, p=0.042; 94% vs 6%, p=0.011) The basal skull fracture was more associated
with carotid artery injury than vertebral artery injury. (100% vs 0%, p=0.0003)
Conclusion: Facet subluxation/dislocation, C1-3 vertebral body fracture and
transverse process fracture involving transverse foramen are the type of fractures
that are frequently associated with carotid or vertebral artery injury.
It is important to assess for vascular injury in a patient with cervical spine fracture
using radiographic imaging.
Vascular imaging may be low-yield in a patient with isolated occipital condyle
fracture.

P 2. MASS CASUALTY PLANNING: A SURVEY OF TEN TEXAS TRAUMA
CENTERS
SE Long, MD; PG Teixeira, MD; TB Coopwood, MD; CVR Brown, MD; JD
Aydelotte, MD
Austin, TX
Background: The general audience of the Disaster and Emergency Preparedness
committee of the Texas Governor’s EMS & Trauma Advisory Council (GETAC)
was polled about cooperation and communication between emergency preparedness
planners (EPP) and clinical providers, specifically in reference to mass casualty incident
planning and preparation. Over 80% suggested there was little to no cooperation
between those who are hired by hospitals to develop the mass casualty plans and
those who are charged with clinically executing them. Members of the committee
were alarmed at this informal result and put together a task force to help answer
this question at the hospital level. Our hypothesis was that the coordination and
communication within major trauma centers in Texas was better than the committee
poll would indicate.
Method: We conducted an in-person survey of ten Level I and II trauma centers in
Texas (Ben Taub, Parkland, Memorial Hermann, University Hospital San Antonio,
San Antonio Military Medical Center, University Medical Center Brackenridge,
South Austin Medical Center, John Peter Smith, Baylor Scott and White-Temple,
and Baylor Scott and White-Dallas). A 31-question survey was administered assessing
perceptions of communication, cooperation, and key elements of each institution’s
mass casualty plans. Four key individuals of the disaster preparedness committee
from each institution were interviewed: the Emergency Planner, the Trauma Medical
Director, a chief Administrator (CMO, COO, CEO), and the Charge Nurse on duty
in the Emergency Department at the time of our visit. The primary outcome was how
often all parties felt that they met expectations in both the development and practice of
mass casualty plans. Secondary outcomes included agreement on who would serve as
the triage officer, which triage system would be used, and awareness of the designated
delayed area in each hospital.
Results: Forty respondents completed the survey for a response rate of 100%. In 80%
of the hospitals, the interviewees considered the coordination and communication for
developing the mass casualty plan either met or exceeded expectations. However, only
40% of the respondents rated the coordination and communication for carrying out
the plan as either met or exceeding expectations. Only 20% of the hospital respondents
agreed on who would function as the triage officer and in only one hospital did all
three respondents agree on which space would serve as the delayed treatment area. 45%
of the respondents were unaware of the location of the delayed area altogether. Only
30% of the charge nurses surveyed had actively participated in the development of the
mass casualty plan for the emergency department and only half had been involved in
practicing the mass casualty plan.

Conclusion: Significant deficiencies in communication and coordination regarding
mass casualty plan execution was identified in the majority of the Texas trauma centers
surveyed. And major disagreement regarding roles and responsibilities during a mass
casualty exist. This seems to validate the original polling numbers and suggests our
hospitals may not be as prepared as expected for a true mass casualty event. A bestpractice model for mass casualty planning and practice should be developed and an
education / support system to standardize the practice in the state is warranted.

P 3. GEOGRAPHIC ANALYSIS OF TRAUMA READMISSIONS IN NORTH
TEXAS
DJ Sanchez MS, RE Gilder RN, M Dome MS, LB Petrey MD
Dallas, TX
Background: Due to the high cost and increased risk of mortality associated with
unplanned patient readmissions, research has aimed to identify risk-factors in patients
with high hospital utilization and recidivism. This study sought to identify geographic
and clinical factors that are predictive of readmissions in trauma patients.
Method: 11 years of data were collected for 21,231 patients admitted to a level 1
trauma center and readmissions following an index trauma admission were identified
over this time. Data was queried from a regional database comprised of 88 member
institutions that encompass more than 150 hospitals in the North Texas region. Patient
ZIP code and county of residence were analyzed using binary logistic regression to
determine significance of predictability of readmission by patient geography. Clinical
variables such as demographics, diagnosis, ISS, procedure, Elixhauser comorbidity,
insurance, and disposition data were also analyzed to create a full clinical and
geographic regression model describing patterns in readmissions.
Results: 4,487 patients were identified as having been readmitted during the data
collection period with a combined 12,235 encounters. 52 variables were identified
as significant predictors of readmissions including 21 geographic variables. Several
counties and patient residence distance to the admitting hospital exhibited higher odds
of readmission. While some ZIP codes were found to show an increased likelihood
of readmission, others were identified as having a decreased likelihood. Median
household income for each significant ZIP code was collected from a demographic
data sharing website. Although income was not tested by statistical analysis, 7 out of
the 12 significant ZIP codes had household incomes below the Texas average with no
observable relation to odds ratio.
Conclusion: This study found that a patient’s location can be used to help determine
a likelihood of readmission following an initial admission for trauma. We believe
that identifying risk factors for readmissions may help to aim targeted interventions
toward patients to reduce chances of readmission and therefore, hospital utilization
and cost. Identifying geographic areas that exhibit high readmission rates may help to
develop outreach programs specialized in serving local patients to ensure adequate postdischarge follow-up and better quality recovery.

P 4. SERIOUS INJURY REPORTING SYSTEMS IN CHILDREN PLAYING
ORGANIZED SPORTS: A SURVEY OF ALL 50 US STATES
P Daher MD, J Aydelotte MD, K Rix MPH, B Ford MD, A Mardock, PG Teixeira
MD, T Coopwood MD, CVR Brown MD
Austin, TX
Background: Participation in school sanctioned sporting events is at an all-time high.
While efforts have been made by some states and private reporting agencies to estimate
injury rates and patterns, no uniform reporting systems exist to capture major injuries
on a large scale. Recent cases of catastrophic injuries sustained in sporting events that
have garnered national attention prompted the authors to identify the overall landscape
of injury reporting systems for both catastrophic injuries, deaths, and minor injuries
sustained during sporting events.
Method: All 50 states’ health departments and state governing athletic bodies were
contacted via phone or email. Both agencies were surveyed to assess the presence and
nature of an athletic injury reporting structure, the types of injuries collected (spinal
cord injury, head injury, abdominal injuries, major fractures, and concussion), and the
location of the compiled data.
Results: 46 out of 50 states responded to our survey. Two states actively declined to
participate and two states failed to respond at all. Twelve states had at least some sort
of state-wide reporting system for sports-related injuries. Eleven states reported that
they partially collected sports injury information, including 8 states (Alaska, Arkansas,
Idaho, Illinois, Indiana, Ohio, Massachusetts, and Michigan) that only reported
concussion and brain injury information (Figure1). Wisconsin collects only voluntary
reported information on hospitalizations. Florida has an organized reporting structure
but not a uniform data collection or storage platform. Nevada has only voluntary
reporting by officials at games for any (but not all) injuries. All of which are highlighted
in grey. Only Hawaii (highlighted in black) reported that they required schools to
report all injuries sustained during athletic competition. Hawaii reports all injuries to
their department of education and are analyzed by the state department of health.
Conclusion: Injury reporting systems for school-sanctioned sports-related injuries are
inconsistent in the United States with only Hawaii having any sort of formalized data
collection for major injuries. Efforts should be made to create an easy to use, standard
reporting system for both state health agencies and athletic governing bodies to capture
injuries.

P 5. INFECTION AFTER PENETRATING BRAIN INJURY -- A DECADE OF
ANALYSIS
LA Harmon MD, LB O’Meara CRNP, MJ Joshi MBBS, TA Paterson MD, A Dhanda
MD, J Kufera MS, TM Scalea MD, DM Stein MD, MPH, DJ Haase MD.
Baltimore, MD
Background: Penetrating brain injuries (PBI) are common, but the incidence of
secondary central nervous system infections (INF) after PBI is poorly described. We
determined the incidence and identified factors predictive of INF after PBI.
Method: We retrospectively reviewed all patients with PBI, age greater than 18 years
who survived over 72 hours, at a level 1 trauma center from 2006 to 2015. Patients were
stratified by the presence or absence of INF. PBI was defined as the evidence of dural
penetration by either CT scan or operative findings.
Data included type of surgical intervention or intracranial pressure (ICP) monitoring,
duration of antibiotic therapy, and type of INF.
Descriptive statistics were calculated for all variables of interest, including age, sex,
abbreviated injury score (AIS), length of antibiotics, length of stay, and disposition.
Mantel-Hansel Chi square test was used to compare distribution of categorical variables
between patients with and without INF. The Wilcoxon’s rank-sum statistic test was
used to compare the distribution of non-parametric variables between the populations.
Results: One hundred and fourteen patients with PBI were identified. Eight patients
(7%) developed INF. Sixty two percent (n=71) of patients underwent operative
intervention. Forty six percent (n=53) of patients had intracerebral pressure (ICP)
monitors placed; 9% developed INF, compared to 5% without ICP monitors (p=0.19).
INF rate was 10% in those patients compared to 2% in patients treated without
operation (p=0.10).
CSF or tissue cultures were obtained on all infections. Four patients (50%) had cultures
positive for Staphylococcus or Propriobacteria. Four patients had negative CSF cultures
but clinical signs of cerebral infection including one parenchymal abscess and three
cases of ventriculitis were treated empirically. Two patients had surgical debridement.
Eighty nine percent of patients (n= 101) received at least one dose of prophylactic
antibiotics. All patients with INF received prophylactic antibiotics and 75% received an
extended course (p=0.04). Prophylactic antibiotics did not impact the development of
INF (p=0.37).
Eighty seven percent (n=7) patients with INF had associated facial fractures and only
one patient with INF had an isolated brain injury. Median Face AIS in patients with
INF was 2 versus 1 in patients without INF (p=0.36).
Median age was 48.5 years in those with INF and 27 years in those without INF
(p=0.02). Mortality was 12.5% and 14%, respectively (p=0.27) Patients with INF had
significantly longer hospitalization (p=0.02).
Conclusion: INF occurs in only 7% of patients with PBI. Patients with INF were more
likely to be older and have associated facial fractures. INF was not higher in patients
treated with operation or ICP monitoring. Prophylactic antibiotics did not reduce the
rate of INF.

P 6. THE HIGH COST OF LARGE BORE TUBE THORACOSTOMY FOR
TRAUMATIC PNEUMOTHORAX
BW Thomas MD, WB Lyman MD, RS Descamp BS, AB Christmas MD, KW
Cunningham MD, RF Sing DO
Charlotte, NC
Background: Tube thoracostomy is a common procedure in patients that have
sustained a traumatic pneumothorax. Within the last five years smaller diameter chest
tubes have been used with increasing frequency to treat traumatic pneumothorax
(PTX) The purpose of this study was to compare small bore chest tubes (SmCT)
as defined as < 20 French (Fr) to large bore chest tubes (LgCT) defined as≥ 20 Fr.
Hospital charges during admission and chest tube related complications were the
primary outcomes.
Method: A retrospective chart review of all trauma patients admitted to a regional
American College of Surgeons verified Level 1 trauma center over a 38 month time
period (01/2013-03/2016) was conducted. Patients requiring chest tube (CT) insertion
for a traumatic pneumothorax either prior to arrival or during their hospitalization
were included. All patients not surviving to removal of their initial chest tube
were excluded. Patients requiring CT insertion for other indications including
hemothorax, hemopneumothorax, and extremis were excluded and Injury Severity
Score (ISS) of each subset was calculated in order to compare patients of similar acuity.
Demographics, interventions, and outcomes were measured. Statistical analyses were
performed using Fischer’s Exact Test and two sample t-tests.
Results: A total of 327 patients received a chest tube for a traumatic PTX. 69.1%
(n=233) had a LgCT initially inserted and 30.9% (n=104) had a SmCT initially
inserted. LgCTs and SmCTs stayed in for an average of 5.8 and 3.0 days respectively.
Primary outcomes for the small vs. large chest tube cohorts are reported in table 1.
Conclusion: Small bore chest tubes (<20 Fr) are associated with a shorter duration
of treatment, lower total hospital charges, and lower incidence of tube thoracostomy
related complications. In light of these findings, small bore chest tubes should be the
initial treatment of choice for traumatic pneumothorax.

P 7. CAN CT IMAGING OF THE CHEST, ABDOMEN, AND PELVIS
IDENTIFY ALL VERTEBRAL INJURIES OF THE THORACOLUMBAR
SPINE WITHOUT DEDICATED REFORMATTING?
J Imran MD, T Madni MD, C Cornelius BS, J Pruitt MD, M Subramanian MD, A
Clark MD, A Mokdad MD, I Nassour MD, J Minei MD, M Cripps MD, A Eastman
MD
Dallas, TX
Background: Patients who sustain blunt trauma are at risk for multiple injuries and
often undergo computed tomography (CT) imaging of the chest, abdomen and spine.
Screening for thoracolumbar spine (TLS) injuries with reformatted CT imaging (CT
T/L) is recommended; however it may not be necessary if CT imaging of the chest,
abdomen, and pelvis (CT CAP) adequately screened for TLS injuries. The objective of
this study was to compare TLS fracture detection rates between CT CAP and CT T/L.
Method: We identified all patients at our institution with a TLS fracture after
sustaining blunt trauma from July 2013 to December 2015. Patients who had both CT
CAP and reformatted CT T/L imaging were included. Patients with isolated cervical
spine fractures or incomplete imaging were excluded. The CT CAP imaging was
reviewed and interpreted by one faculty radiologist who was blinded to the results of
the reformatted images. Fractures were divided into groups based on type and location
of fracture. The sensitivity of CT CAP to identify fracture was calculated for each
fracture type. Continuous variables were represented as median and interquartile range
(IQR) and categorical variables were expressed as percentages.
Results: A total of 514 TLS fractures were identified in 125 patients using reformatted
CT T/L spine imaging, with an equal number of lumbar and thoracic fractures.
Multilevel fractures found in 33 patients (26.4%). The sensitivity of CT CAP for
detecting TLS compression/vertebral body fractures and chance/burst fractures was
77% and 96%, respectively. Overall, 79 fractures (15%) were missed on CT CAP
that were identified on CT T/L. However, only one fracture that was missed on CT
CAP required therapy (bracing). Eleven vertebral body compression fractures with no
height loss and one thoracic burst fracture were missed on CT CAP. Those with missed
compression fractures did not require intervention. The median patient age and injury
severity score were 43 years (IQR 30-53 years) and 27 (17-34), respectively.
Conclusion: CT CAP could potentially be used as a screening tool for clinically
significant TLS injuries. Improvements in imaging technologies should improve
detection of present but clinically insignificant fractures.

P 8. POST-TRANSFER TUBE THORACOSTOMY PLACEMENT AMONG
TRAUMA PATIENTS DIAGNOSED WITH A PNEUMOTHORAX OR
HEMOTHORAX: IS IT ASSOCIATED WITH POOR OUTCOMES?

Babawale Oluborode MD, Prasenjeet Motghare, Mary K. Lindemuth MD, Roxie M
Albrecht MD, Aaron Scifres MD
Oklahoma City, OK
Background: Tube thoracostomy is commonly utilized in the trauma patient
population. The benefits of tube thoracostomy placement can be immediate and lifesaving, though there are inherent risks. In all patients diagnosed with pneumothorax or
hemothorax, Advanced Trauma Life Support (ATLS) guidelines currently recommend
tube thoracostomy prior to transfer to definitive care facility. The purpose of this
investigation is to describe the demographic characteristics, clinical characteristics
and outcomes of chest trauma patients transferred to a Level 1 trauma center based on
pre- and post-transfer tube thoracostomy placement. We hypothesize that pre-transfer
placement of chest tubes does not improve outcomes in the trauma population and
therefore may unnecessarily delay transfer to definitive care.
Method: A retrospective study based on a cohort of chest trauma patients transferred
to a Level I trauma center between January 2013 and June 2014. These patients carried
the diagnosis of either pneumothorax or hemothorax, both with tube thoracostomy.
Initially, 310 patient charts were reviewed. Exclusion criteria included patients
were excluded for being under age 18, the diagnosis of bilateral pneumothoraces or
hemothoraces, or a diagnosis of a pneumothorax or hemothorax that was not evident
upon review of plain chest radiograph taken at presentation. Outcomes data was
analyzed for the remaining patients.
Results: Of the initial 310 patients, 77 met study eligibility. Thirty-eight patients had
a chest tube placed by outside facility prior to transfer to our trauma center, while 39
had initial chest tube placed after transfer. There was no statistical significance in the
demographics or comorbidities between the patient populations.
Despite the presenting similarities, trends were noted in length of stay and days on
ventilator; both were decreased in the patient population who received their chest tube
after transfer. Complication rates between the two groups were nearly identical, though
there was a slight trend towards higher rate of dislodgement in chest tubes placed prior
to transfer.
Interestingly, statistical significance was noted in the need for additional procedures,
with 50% of all patients who had underwent chest tube prior to transfer requiring
either additional chest tubes, video-assisted thoracoscopy, or formal thoracotomy. Of
the patients who received their initial tube thoracostomy after transfer, less than 13%
required additional procedures for pleural pathology.
Conclusion: This survey of one trauma center’s patient population suggests that
deferring tube thoracostomy placement until after transfer to definitive facility may be
a safe strategy for management of hemodynamically stable traumatic pneumothoraces
and hemothoraces. It may also serve to spare patients further invasive procedures.
However, future, large-scale studies are needed to assess the risks and benefits of tube
thoracostomy placement in trauma patients prior to transfer to trauma centers.

P 9. PRE-HOSPITAL SPINAL IMMOBILIZATION: NEUROLOGICAL
OUTCOMES FOR SPINAL MOTION RESTRICTION VS. SPINAL
IMMOBILIZATION
A Nilhas MD, RM Drake MEd, SD Helmer PhD, J Reyes MEd, M Foster MD, JM
Haan MD
Wichita, KS
Background: A new recommendation for EMS spinal precautions limits long
spinal board (LSB) use to extrication purposes only. The purpose of this study
was to determine neurological outcomes for spinal motion restriction vs. spinal
immobilization using LSB.
Method: Beginning in January 1, 2014, a protocol for selective use of LSB was
instituted by EMS with the agreement that LSB would not be used if patients were
oriented, not clinically under influence of alcohol/drugs, without distracting injury,
and without spinal tenderness. A 2-year retrospective review was conducted of all
trauma patients admitted to a level 1 trauma center with documented spinal injury,
while using the selective protocol. Demographics, accident events, injury severity
scores (ISS), Glasgow Coma Scale (GCS) scores, alcohol/drug screen, and neurologic
assessments from EMS, trauma teams, and hospital staff were collected for those
transported with or without LSB.
Results: Of the 277 trauma patients reviewed, 25 (9.0%) had LSB in place upon
arrival. Thirty-five (12.6%) patients had previous neurologic deficit/diagnosis. Patients
placed on LSB more often had documented neurological deficits by EMS (30.4% vs.
8.8%, P=0.01) and the trauma team (29.2% vs. 10.9%, P=0.02). Patients placed on LSB
were more often moderately or severely injured [ISS>15 (36.0% vs. 9.9%, P=0.001)] and
had a GCS <9 (12.0% vs. 2.8%), but this was not statistically significant (P>0.05). Of
note, there was an increased motor deficit noted from post extraction to trauma team
(4.4% vs 8.5%) for those not on LSB. On further review, in all but one instance these
were patients with peripheral nerve deficits and extremity fracture. The final patient
had an L1 fracture with diffuse weakness of bilateral lower and upper extremities,
which later improved. As such, no progression of injury occurred in any patient with
and without LSB.
Conclusion: This study suggests that LSB is being properly used in the majority of
more critically injured patients. No progression of injury was identified in patients with
spinal injury, even without long board immobilization. Further research is needed to
compare neurological outcomes for spinal restriction vs. immobilization using a larger
sample size and more consistent documentation of pre-extraction EMS examination.

P 10. RIDE-SHARING PLATFORM TECHNOLOGY’S IMPACT ON DRUNK
DRIVING CRASHES AND DEATHS
E Ross MD, S Radpour MA, PGR Teixeira MD, TB Coopwood MD, CVR Brown
MD, JD Aydelotte MD
Austin, TX
Background: Drunk driving represents a severe public health problem in the state
of Texas. In 2014, 14.5% of all alcohol involved traffic fatalities in the United States
occurred in Texas. Mothers Against Drunk Driving estimates the 2013 taxpayer
burden of alcohol related crashes in Texas at $6.2 billion. According to the University
of Washington’s Institute of Health Metrics and Evaluation, in 2012 Travis County
had rates of any alcohol consumption, heavy drinking and binge drinking above the
national average. Ride-sharing companies such as Uber and Lyft began to operate in
Austin in the Spring of 2014. A study in Seattle, Washington, found that drunk driving
arrests decreased after the implementation of ride-sharing platforms. Our hypothesis
was that the emergence of ride-sharing platforms contributed to an overall decrease in
drunk driving crashes and deaths in our city.
Method: All crashes and deaths involving drunk drivers recorded in the Texas
Department of Transportation’s (TxDoT) Crash Records Information System (CRIS)
database for Travis County were extracted from May 2011 through August 2015.
In order to correct for changes in traffic volumes, total vehicle traffic, calculated as
millions of vehicles per month (mvpm) was estimated by the TxDoT Traffic Count
Database System (TCDS) at two permanent points in Travis County. This system
serves as part of the the raw data for vehicle miles travelled as reported to the US
Department of Transportation. Time periods were compared as monthly averages in
the entire period prior to ride sharing implementation (PreRide) and after the platforms
were implemented in Austin (PostRide). The two time periods (pre and post-ride
sharing implementation were compared using a student’s t-test.
Results: PreRide and PostRide drunk driving crashes (43.6, 44.2, p=0.81), deaths (3.3,
3.2, p=0.81) and vehicle traffic (10.0 mvpm, 10.1 mvpm, p=0.46) were compared. The
monthly rate of drunk driving crashes per million vehicles was 4.3 crashes per mvpm
in the PreRide period and 4.4 crashes per mvpm in the PostRide period (p=0.63). The
monthly rate of drunk driving fatalities per million vehicles was 0.33 deaths/mvpm in
the PreRide period and 0.32 deaths/mvpm in the PostRide period (p=0.84).
Conclusion: There does not appear to be an association with ride-sharing platforms
and a decrease in drunk driving crashes or deaths in Austin, TX. A larger, multi-city/
multi-state, study should be done over a longer time period to better analyze the data.

P 12. HAWAII: ISLANDS OF PARADISE- AND PERFORATED DUODENAL
ULCERS
C Souther MD, WL Biffl MD
Honolulu, HI
Background: The incidence of complications from duodenal ulcers has been decreasing
since the introduction of proton-pump inhibitor (PPI) therapy. Despite this trend in
the literature, we seem to see perforated duodenal ulcers relatively frequently in our
local hospitals in Hawaii. The purpose of this study was to determine whether the
incidence of perforated duodenal ulcers is truly higher in Hawaii and to characterize
the patient population.
Method: A retrospective review was conducted using data obtained from the
Healthcare Cost and Utilization Project (HCUP) database provided by the US
Department of Health and Human Services. The total number of hospital discharges
with the principal diagnosis of chronic duodenal ulcer with perforation (ICD-9 code
532.50) and associated demographic data were obtained from the state of Hawaii and
from the national level (which includes 47 states) during the years of 1997 through
2013. The data from Hawaii were compared with national numbers using T-tests (a
p-value of <0.05 was considered significant).
Results: From 1997 to 2013, a significantly higher proportion of hospital discharges
in Hawaii (17.8 cases per 100,000 hospital discharges) were associated with a principal
diagnosis of perforated duodenal ulcer than in the US as a whole (13.7 cases per
100,000 hospital discharges; p=0.006), with cases increasing in Hawaii throughout
the study period (Figure 1). A significantly higher percentage of these patients were
discharged home in Hawaii than at the national level (p=0.002). The mean charges
for these hospitalizations were significantly different between Hawaii and the entire
US ($48,754 and $61,666 respectively; p=0.027). The mean age of these patients was
similar in Hawaii and nationally (59.6 vs 61.5; p=.097).
Conclusion: The diagnosis of chronic duodenal ulcer with perforation was seen more
frequently in Hawaii than in the US as a whole during the time period between 1997
and 2013. This may be due to lower accessibility of PPIs especially for patients who
have recently moved from other Pacific Islands. More of the patients were discharged
directly home and the average charges were lower in Hawaii which may be due to the
familiarity of managing this disease process due to its higher incidence. In contrast to
the rest of the US, perforated duodenal ulcers remain an important surgical problem
in Hawaii. This regional variation in incidence should prompt further investigation to
elicit the causative factors so that earlier interventions can be made.

Background: Tornados are among the deadliest of all natural disasters. Each year,
approximately 2,000 tornados occur worldwide. The purpose of this study was to
characterize patterns of injury in adult and pediatric patients treated at at a combined
pediatric and adult trauma center.
Method: After institutional IRB approval, patients treated with tornado-associated
injuries were identified from the trauma registry at a combined pediatric and adult
trauma center.
Results: During the study period from May 1999-June 2013, 96 patients were
seen as trauma activations corresponding to two EF5 and four EF4 tornados in the
surrounding community, 38 pediatric and 58 adult patients. There were tendencies to
different presentations between groups in terms of injuries, interventions and hospital
length of stay. (Table 1) Pediatric patients were more likely to be male (70% vs. 50%),
have soft tissue injuries (61% versus 31%) and long bone fractures (26% versus 17%).
TBI was common in both groups (18% versus 21%). Children were less likely to have
spine fractures (3% versus 43%) and no spinal cord injuries were identified in pediatric
patients (0% versus 7%).
Conclusion: This patient cohort represents the highest concentration of deadly
tornados in one geographic area. Since Mmulti-system injuries were common in ;
both pediatric and adult patients, tornado victims should be delivered to benefit from
treatment at trauma centers capable of providing multidisciplinary care.

P 16. OUTCOMES OF RURAL TRAUMA PATIENTS WHO UNDERGO
DAMAGE CONTROL LAPAROTOMY
PA Harwell MD, J Reyes MEd, SD Helmer PhD, JM Haan MD
Wichita, KS
Background: Rural trauma patients have nearly twice the mortality of their urban
counterparts. A majority of fatal motor vehicle collisions occur in a rural setting. While
rural hospitals may be ill-equipped to treat these patients long-term, there may be a role
for operative stabilization before transfer to higher-level trauma centers.
Method: A 5-year retrospective review was conducted of all trauma patients≥18 years
of age with abdominal injuries transferred to an ACS verified Level 1 Trauma Center
from a rural facility. Demographics, injury severity and details, operative procedures,
and hospitalization outcomes were evaluated for those patients who had a damage
control laparotomy performed at an outside hospital (DCL), were considered unstable
and had an exploratory laparotomy within two hours of arrival from an outside hospital
(ILU), or were considered stable and had an exploratory laparotomy within two hours
of arrival from an outside hospital (ILS).
Results: Among the 16 patients included in this study, 25% (n=4) had DCL, 25%
(n=4) had ILU, and 50% (n=8) had ILS. Only 18.8% (n=3) of patients sustained
penetrating injuries. All other injuries were from blunt trauma. Half of the DCL group
had significant intra-abdominal vascular injuries. Three patients in the ILU group had
significant intra-abdominal injuries and two patients were hypotensive on arrival. Small
bowel and colon injuries were more common in ILS. All patients in DCL and ILS
survived while no patients in ILU survived hospitalization (see table).
Conclusion: While this study has limited patients for comparison, the data would
support that a patient’s mortality is improved with damage control laparotomy prior to
transfer in unstable trauma patients.

P 17. GLOBAL HEALTH OPPORTUNITIES: DOES INTEREST EQUAL
ACTION?
AM Pasley DO, ES Wise MD, U Shah, S Gupta MD, N Hansraj MD, JD Pasley DO,
A Kushner MD, M Brenner MD, JJ Diaz MD
Baltimore, MD
Background: Trauma has become a worldwide pandemic projected to be the 4th
leading cause of death by 2030, the burden of which is highest in low-and-middle
income countries (LMICs). Interest to help tackle this global burden of injury
is rising within the trauma community after the Haiti earthquake and Typhoon
Haiyan. It is unknown whether surgical critical care fellowship programs (SCCFP)
offer opportunities in this area, or if these experiences are represented at national
conferences.
Method: All ACGME SCCFP websites were identified. Inclusion criteria included
mention of global or international opportunities for fellows. Details of opportunities
were recorded. Program brochures from The American Association for the Surgery of
Trauma (AAST), Eastern Association for the Surgery of Trauma (EAST), and Western
Trauma Association (WTA) from 2015 and 2016 meetings were examined to determine
the number of presentations discussing global/international health issues.
Results: 110 SCCFP were identified. Four (3.6%) programs mention an international/
global trauma opportunity. One level 1 trauma center mentions the opportunity to
be exposed to international trauma systems, another advertises opportunity to “train
abroad” with no further specifications, and a third describes opportunities of “global
health” to develop programs in “economy-restricted environments”. A fourth program
describes direct international collaboration with an international trauma society.
Representation of this topic on a national forum is equally dismal; in 2015, zero of 208
presentations were on global health (0.0%), in 2016 only three of 376 presentations
(0.008%) discussed the topic.
Conclusion: Despite a recognized need and interest in global trauma care, there is a
clear lack of opportunity available to prospective applicants to SCCFP. The almost
absent representation of such experiences at national meetings is likely a direct
outcome of this unfortunate reality. Educational relationships with accredited SCCFP
and LMIC collaborators would provide a valuable opportunity to trainees while
concurrently helping to improve global trauma care.

P 18. LAPAROSCOPIC APPENDECTOMY IN THE NON-ACUTE APPENDIX:
IS IT APPROPRIATE?
DL Wyrick MD, AT Mancino MD
Little Rock, AR
Background: Although laparoscopy is the common approach to appendectomy for
acute appendicitis, there is debate on the preferred approach for appendiceal masses and
mucoceles. Our aim was to review our experience with management of these entities.
Method: We reviewed our surgical database for appendectomies performed for
reasons other than appendicitis, in the period from July 2006 to October 2016. Basic
demographic information, diagnostic modality, symptoms, indication for procedure,
operation performed, and final pathology were collected and analyzed.
Results: Eleven cases were identified, all were male. The median age was 60 years. Five
were African American and the remainder were Caucasian.
Seven patients were asymptomatic; four were identified incidentally on computed
tomography (CT) and three on screening colonoscopy. Four patients presented with
pain and appendiceal pathology was diagnosed on CT.
Preoperative diagnosis included two appendiceal masses, three polyps, and six
mucoceles. Eight of the operations were approached laparoscopically with one
conversion to open due to difficult dissection. The remainder were done via an
open approach; two due to previous surgeries/adhesions and one due to concern for
mucinous cancer. Appendectomy was performed on all, including a portion of cecum
on the three patients with polyps at appendiceal orifice. Final pathology on the two
masses were an angiomyolipoma and a carcinoid tumor. The three polyps were benign.
The final pathology on the mucoceles included three low grade mucinous neoplasms,
one mucocele, and one benign appendix. No patients needed further resection after
review of final pathology.
Conclusion: Laparoscopy is an effective technique in the management of these
uncommon appendiceal pathologies. Appendectomy with additional partial cecectomy
or hemicolectomy should performed as indicated. Conversion to open should be
considered in the face of difficult dissection to prevent spillage of mucin.

P 20. EPIDEMIOLOGY PROJECT REVEALS SIGNIFICANTLY LOWER
INCIDENCE OF FUNCTIONAL GALLBLADDER DISORDER THAN THE
STATE AND NATIONWIDE ADMINISTRATIVE DATABASE
MO Mohamed MBBS, CA Thiels DO, J Bingener MD
Rochester, MN
Background: Recently, several authors have postulated that there is an unjustified
increase in the use of cholecystectomy for functional gallbladder disorder (FGBD)
nationwide based on large administrative data sets. We aimed to identify the incidence
and the cholecystectomy rate for FGBD in an epidemiologically well-defined
population and to compare results to previously published administrative data.
Method: After IRB approval had been obtained, we extracted data from the Rochester
Epidemiology Project (REP), a unique population-based research infrastructure
system that links together nearly all of the medical records of residents of Olmsted
County, MN. Olmsted County includes a community and a teaching hospital serving
a population base of about 135,000 people. Similar to other studies, we used ICD9 codes for “˜gallbladder disease not elsewhere specified’ (575.8) and “˜unspecified
disorder of gallbladder’ (575.9) to identify all patients with FGBD from 2000 to 2014.
Medical records were abstracted for demographics, diagnostic testing, additional
diagnosis and imaging findings including HIDA scan. Patients with the concomitant
diagnosis of cholelithiasis were excluded.
Results: Over a 15-year period, after excluding patients with cholelithiasis (n=354), we
identified 253 patients with a CPT code for unspecified gallbladder disease. Of those,
184 patients had other confirmed diagnosis such as Primary Sclerosing Cholangitis.
Sixty-nine patients had biliary symptoms with no gallstones on ultrasound. In the
community hospital, 22/25 (88%) of the patients underwent HIDA scan as part of the
diagnostic workup compared to 18/44 (41%) in the teaching hospital. Based on the
review of their medical records 24 of these patients had confirmed FGBD, 20 women
(83%), mean age 38.2±14.4 years.The incidence of FGBD in Olmsted County was
1.77/10,000. (15/141 (11%) of patients with ICD-9 code 575.8 and 9/112 (8%) with
ICD-9 code 575.9). The rate of cholecystectomy for FGBD was 70% at both hospitals.
Conclusion: The incidence of FGBD in Olmsted County (1.7) was much lower than
the previously published incidence in administrative data for Minnesota 3.0/100,000.
In our study, only a small fraction of patients (11%) with the ICD-9 codes for
unspecified gallbladder diagnosis had FGBD compared to the State Inpatient Sample
which postulated that FGBD accounted for more than 80% of administrative code
575.8. Medical diagnosis patterns differed between teaching and community hospitals,
whereas the cholecystectomy rate was similar between the two hospitals (around
70%) and only slightly lower than the previously published rate in a nationwide
sample (78%). Additional investigation may be needed to understand if the rate of
cholecystectomy is truly increasing.

P 21. PHEOCHROMOCYTOMA: A CASE OF DEVASTATING RESPIRATORY
FAILURE WITH ECMO SALVAGE
Greenleaf CE MD, Griffin LA MD,Cox KM MD Shake JE MD , Orr WS MD
Jackson, MS
Background: Pheochromocytoma (Pheo) is an uncommon adrenal tumor that
typically presents with headaches, sweating, palpitations, and paroxysmal hypertension
(HTN). Surgical resection of Pheo is the curative treatment. Preoperative management
includes alpha-blockade and volume expansion followed by beta-blockade, after
sufficient alpha-blockade has been established in order to prevent hypertensive crisis.
Pheo crisis can lead to cardiomyopathy, pulmonary edema, and total circulatory
collapse.
Method: Here we describe our experience with a patient who was transferred to our
institution with Pheo crisis in hypoxic respiratory failure requiring extracorporeal
membrane oxygenation (ECMO) to stabilize prior to surgical resection of a left Pheo.
Results: A 37 year old female presented to an outside hospital (OSH) with complaints
of nausea, vomiting and abdominal pain. In the emergency department (ED), she had a
syncopal episode, and was found to be hypoxic with oxygen saturations in the 80s and
profoundly hypertensive with a blood pressure (BP) of 200s/100s. She was intubated
and transferred to our tertiary center.
Upon arrival, she was found to have worsening oxygenation and ventilation (OV)
despite increasing ventilatory support. Initial arterial blood gas showed a pH of 6.8,
pCO2 of 51, pO2 of 71 and a lactate of 10. She was admitted to the medical intensive
care unit (MICU). Multiple ventilatory modes to improve respiratory status were tried
unsuccessfully. The patient also had BP lability with systolic BP ranging from the 80s
to 200s. Due to failure to ventilate and oxygenate, she was placed on veno-venous
ECMO (ECMO). Her OV markedly improved.
After stabilization, further work-up was obtained. Family discussion revealed the
patient had a long history of refractory HTN as well as a history of intermittent
headaches and palpitations. Due to financial strain, the patient had not been able
to afford her anti-hypertensive medications for two weeks prior to presentation.
Computerized tomography scan showed bilateral, diffuse areas of ground glass opacity
in the lung parenchyma as well as a large left adrenal mass. Laboratory work-up
revealed elevated serum and urinary metanephrines.
The patient spent 3 days on ECMO and temporary hemodialysis. After two weeks of
alpha blockade, the patient underwent an open left adrenalectomy. Final pathology
showed Pheo without local invasion. The patient was discharged on only one antihypertensive medication, and at two months postoperatively she was found to be doing
well with a BP of 120/80 and normal kidney function.
Conclusion: This case highlights the difficulty in the management of cardiogenic
shock and respiratory failure secondary to pheochromocytoma and the important role
that ECMO can have in the successful resuscitation and management of these patients.

P 22. DIRECT PERITONEAL RESUSCITATION IN SEVERE NECROTIZING
PANCREATITIS: A STRATEGY FOR PREVENTION OF ABDOMINAL
COMPARTMENT SYNDROME? A CASE REPORT
AM Pasley DO, L O’Meara CRNP, F Boulos MD, N Hansraj MD, B Eaton CRNP,
JD Pasley DO, R Tesoriero MD, JJ Diaz MD.
Baltimore, MD
Background: Intra-abdominal hypertension (IAH) complicates 15-60% of severe
acute pancreatitis (SAP) cases. Up to 30% develop abdominal compartment syndrome
(ACS) with mortality rates as high as 75%. The use of direct peritoneal resuscitation
(DPR) has been shown to increase primary fascial closure and reduce intra-abdominal
complications in acute care surgery due to reductions in crystalloid infusion and
prevention of visceral edema. We hypothesized that DPR may be able to mitigate ACS
in patients with SAP.
Method: We present a case report describing the use of DPR to prevent ACS in SAP.
Results: A 54 year old male presented with acute necrotizing pancreatitis with a
computed tomography severity index (CTSI) of 9. He was intubated for rapidly
progressive respiratory failure and despite ongoing resuscitation developed circulatory
failure requiring three vasopressors, acute kidney injury, and ACS. He was taken to
the operating room and a standard peritoneal dialysis catheter was placed. He received
DPR with 2.5% Deflex; 1 liter infusion with a 1 hour dwell time every 4 hours. Over
the next three days he gradually improved [post-operative day (POD) 1; bladder
pressure (BP): 25, urine output (UO): 505 milliliters (mL), vasopressors: 3. POD 2; BP:
16, UO: 1700 mL, vasopressor: 1. POD 3 BP: 13, UO: 2735 mL, vasopressors: 0.] He
received a tracheostomy due to prolonged respiratory failure and was discharged to a
rehabilitation center on hospital day 37 without permanent organ failure.
Conclusion: Due to need for aggressive fluid resuscitation in SAP there is an increased
risk for ACS. Patients failing medical management require decompressive laparotomy
with significant morbidity and mortality. As an alternative, DPR may be able to treat
and prevent ACS in the setting of SAP.

P 23. ACE INHIBITOR INDUCED INTESTINAL ANGIOEDEMA: A LITTLE
KNOWN BUT SIMPLY CORRECTED PROCESS CONFUSED WITH
INTESTINAL ISCHEMIA
SW Ross MD, VA Augenstein MD, BW Thomas MD, Avery MJ BS, Heniford BT,
Sing RF
Charlotte, NC
Background: Angiotensin converting enzyme inhibitors (ACE-i) are the most
commonly prescribed anti-hypertensives in the US. Oropharyngeal and lingual
angioedema related to ACE-i is a well-recognized allergic reaction to the drug. Less well
known is that the small intestine can also experience the same swelling, edema, and
hyperemia that can often have a similar radiographic appearance to intestinal ischemia
(Figure). There have been less than 30 case reports in the literature of this phenomenon
and, herein, we report our experience with of ACE-i induced intestinal angioedema.
Method: A retrospective analysis was performed of all cases of suspected ACE-i
induced bowel angioedema evaluated by an Acute Care Surgery service at a regional
tertiary referral center, from 2010 to 2016. The primary outcomes of interest were
resolution of symptoms, readmission, any surgical intervention. Standard descriptive
statistical tests were used.
Results: Fourteen patients were identified over the time period, all with surgery
consulted for concern for enteritis with bowel ischemia. Patient mean age was 46 ±
15 years and 78.6% of patients were female. Patients most commonly had symptoms
of abdominal pain (100%), nausea (71.4%), emesis (57.1%), diarrhea (21.4%), and
a leukocytosis (64.3%). 28.6% of patients were admitted from clinic with 71.4%
presenting from the emergency department. Only 3 patients (21.4%) had a diagnosis
of ACE-I induced angioedema at admission. Time from onset of symptoms from
initiation of ACE-i was variable with a range of 1 - 709 days, with a mean time of 188.6
± 226.0 days. On CT scan 100% had bowel wall thickening, 50% had surrounding
edema, and 35.7% had surrounding free fluid. On initial admission no patients were
taken to surgery, but only 6 (42.9%) had correct diagnosis and discontinuation of
ACE-I; 8 (57.2%) had supportive care. Of those with ACE-I discontinuation, none had
recurrence of symptoms, but of those still taking ACE-I, 7/8 (87.5%) were readmitted.
3/8 (37.5%) had endoscopy during the readmission, but only 2/8 (25%) had ACE-I
discontinued on readmission. 4/6 (50%) patients still on ACE-i then represented for
a second readmission. All these patients eventually had ACE-i discontinued and had
resolution of symptoms. Two patients were lost to follow-up.
Conclusion: ACE-I induced angioedema is a rare disorder with a worrisome radiologic
appearance, but benign straightforward course if the medication is discontinued in a
timely fashion. Similar to the oral angioedema, ACE-I induced intestinal angioedema
can present years after initiation of therapy, and therefore can be very hard to
diagnose if not clinically suspicious. Failure to recognize the condition will result in
delayed diagnosis, return of symptoms, and readmission until the ACE-i use has been
discontinued. However, while often consulted to evaluate as a surgical emergency, in
our experience this clinical entity does not require surgical intervention.

P 24. GALLBLADDER WALL THICKNESS MEASURED ON ULTRASOUND:
IS IT ASSOCIATED WITH OPERATIVE TIME AND SURGICAL
PATHOLOGY?
RS Watson MD, KA Brusky BS, AJ Borgert PhD, KJ Kallies MS, SN Kothari MD
La Crosse, WI
Background: Ultrasound (US) is the primary initial imaging study to diagnose
potential gallbladder pathology as it is efficient, noninvasive, cost-effective, and is
highly accurate. Gallbladder wall thickness is routinely measured on initial US and
incorporated into the evaluation of patients with various gallbladder pathologies. The
impact of gallbladder wall thickness area of interest for many, however large series are
relatively missing from the literature, and correlation with pathologic measurement and
severity are not widely reported.
Method: A retrospective review of the medical records of all patients who underwent
cholecystectomy at our community teaching hospital from January 2013 through
April 2016 was completed. Gallbladder wall thickness measured by US was compared
to pathology measurements. US wall thickness was also correlated with pathologic
severity, graded as follows: 1. Normal gallbladder, 2. Cholelithiasis, 3. Chronic
cholecystitis, 4. Acute on chronic cholecystitis, 5. Acute cholecystitis, 6. Gangrenous
cholecystitis. Statistical analysis included Wilcoxon sign test, and Pearson correlation.
Results: There were 976 patients included, 68% were female. Mean age
and BMI was 49.2 ± 18.1 years and 32.2 ± 7.4 kg/m2, respectively. Thirtythree percent of cholecystectomies were performed urgently, and 98.7% were
performed laparoscopically. Intraoperative cholangiograms were done in 65% of
cholecystectomies. Median operative time was 77 minutes (20 - 292). Mean common
bile duct diameter was 5.1 ± 2.4 mm. The mean gallbladder wall thickness was 3.4 ±
2.1mm on US, and 3.8 ± 2.6mm on pathology. Gallbladder wall thickness on US was
strongly correlated with wall thickness on pathology (r = 0.44, P<0.001). Operative
time increased with thickness of the gallbladder wall on ultrasound with (r = 0.29, P<
0.0001) and on linear regression analysis, each mm of wall thickness correlated to an
increase of 5.1 minutes in operative time. The mean differences between gallbladder
wall thickness on US vs. pathology were greater as pathologic severity increased (0.7
mm difference for least severe vs. 3.4 for most severe; P<0.001).
Conclusion: This is one of the largest series evaluating ultrasound predicting operative
outcomes and provides definitive data on the subject. Increased wall thickness
correlated to more difficult operations as indicated by the increase in operative time.
Contrary to previous studies in the literature, we did not observe any significant
difference in conversion to laparotomy or complications with increasing wall thickness.
Gallbladder wall thickness on ultrasound becomes less accurate compared to pathology
with increasing severity of disease. These data suggest that increasing gallbladder wall
thickness could be included in preoperative planning for equipment needs, timing of
intervention, availability of assistants and anesthesia considerations.

P 25. SAFETY AND FEASIBILITY OF SEMI-RIGID INCOMPLETE
ANNULOPLASTY RING IMPLANTATION FOR FUNCTIONAL MITRAL
REGURGITATION
PG Chan MD, EG Chan MD, C Hamilton, D Chu MD
Pittsburgh, PA
Background: Previous studies have shown that incomplete mitral annuloplasty
ring implantation incurs poor freedom from recurrent mitral regurgitation (MR) in
patients with functional mitral regurgitation (FMR). Recently, semi-rigid incomplete
mitral annuloplasty rings with preservation of intercommissural distance have been
introduced. We hypothesize that semi-rigid incomplete mitral annuloplasty rings are
safe and feasible treatment option for patients with FMR.
Method: From January 2011 to 2016, fifty-three consecutive patients underwent mitral
valve repair for FMR in a single quaternary referral institution. Safety and feasibility
were evaluated by percentage completion of mitral valve repair, mortality, and freedom
from recurrent MR (defined as >2+) as determined by echocardiograms.
Results: The mean age for the cohort is 66.8±1.9 years old. Completion of implantation
of the semi-rigid mitral annuloplasty ring was 100%. 30-day and 1-year mortality rates
were 1.9% and 3.7% respectively. Freedom from recurrent MR was 90.6% (48/53)
during median follow up period of 11 months.
Conclusion: In the surgical treatment of FMR, semi-rigid incomplete mitral
annuloplasty ring may be considered a safe and feasible alternative with low mortality
rates and high freedom from recurrent MR.

P 26. STRAY ENERGY TRANSFER TO REINFORCED ENDOTRACHEAL
TUBES DURING NECK SURGERY
SA Hilton MD, E Jones MD, A Kiourti PhD, S Bojja-venkatakrishnan MS, A Madani
MD PhD, DM Overbey MD, DJ Mikami MD, JW Hazey MD, TS Jones MD, TN
Robinson MD
Aurora, CO
Background: Energy based devices are used in virtually all operations for dissection
and hemostasis. Ensuring a dry operative field is especially important in head and neck
operations where hematoma formation can result in airway compromise. Reinforced
endotracheal tubes are widely used to protect the airway during head and neck surgery.
These tubes are reinforced with a coiled metal wire that could absorb stray energy from
common electrosurgical devices resulting in airway injury. The purpose of this study
was to confirm stray energy transfer to reinforced endotracheal tubes and to identify
surgeon-controlled factors that may reduce this energy transfer.
Method: A 7 Fr, reinforced endotracheal was placed in a live porcine model. A
standard monpolar “bovie” pencil, an advanced bipolar device and an ultrasonic device
were activated for 5 seconds or one cycle on the superficial and deep tissues of the neck.
Stray energy was measured with radiofrequency energy probes placed around the cable
to the energy device (energy input) and the reinforced endotracheal tube as it emerged
from the animal’s mouth (stray energy). Stray energy transfer was compared to control
(no energy activation) with statistical significant set at p < 0.05.
Results: Stray energy is transferred to the reinforced ETT with all energy types. (Table
1). The use of energy devices in deep tissue transfers significantly more energy than on
the skin (3270±170.3 vs. 57.4±15.7 milliAmps, p<0.001). Bipolar and ultrasonic devices
do result in stray energy transfer to the endotracheal tube but the overall amount is an
order of magnitude less. Using cut mode instead of coag mode also reduces the amount
of stay energy transfer in the superficial and deep tissues of the neck (502±115.5
vs. 3270±170.3 mA, p<0.001 for deep neck tissue; 12.8±8.3 vs. 57.4±15.7 mA for
superficial tissue, p<0.001).
Conclusion: Stray energy is transferred to the wires within a reinforced endotracheal
tube during neck surgery. The amount of energy transferred is significantly higher with
monopolar energy compared to bipolar or ultrasonic energy. Surgeons can decrease the
risk of stray energy transfer by avoiding reinforced endotracheal tubes or using bipolar
or ultrasonic energy devices during deep neck dissection.

P 27. THE SENSITIVITY OF 4D MRI IN PREOPERATIVE LOCALIZATION
OF PARATHYROID ADENOMA IS INFLUENCED BY THE SIZE OF THE
ADENOMA
KO Memeh MD, JE Palacios, MA Guerrero MD
Tucson, AZ
Background: 4D MRI is a relatively novel image modality for pre-operative
localization of parathyroid adenoma in patients with primary hyperparathyroidism
( PHPT).Experience with this image modality for this specific indication continues
to evolve. Our group has previously demonstrated the superiority of 4D MRI over
conventional imaging in the diagnosis of single gland parathyroid adenoma (PTA). We
have also showed that 4D MRI performs well in quadrant localization of single gland
PTA but poorly identifies and/or localizes multi-gland PTA. In this study, we set out to
determine if the size of the diseased gland(s) has any role in the performance of the 4D
MRI in the diagnosis and correct localization of PTA.
Method: We analysed and matched the result of 4D MRI of all patients who
underwent parathyroidectomy at our center between Feb 2015 and May 2016 with
the intra-operative findings. All resections were confirmed successful with adequate
decrease in intraoperative PTH as defined by the Miami criteria. We then examined
the effect of size of parathyroid lesion (as measured by the pathologist) on the
performance of the 4D MRI as mentioned above.
Results: 26 patients underwent parathyroidectomy for PHPT after undergoing pre-op
localization with 4D MRI. 14 patients had single gland while 12 patients had multigland PTA respectively. MRI accurately diagnosed all 26 patients as having PTA
preoperatively. It also identified and quadrant localized the adenoma in all 14 patients
with single gland PTA. However, it was only able to correctly diagnosed 33% of the 12
patients as having multi-gland disease. There was a statistically significant difference
between the mean diameter of the single gland PTA and the multi-gland PTA
respectively [ 2.11cm ( 1- 4.2cm) vs 1.33cm( 0.7-2.1)P< 0.05].
Conclusion: Our cohort study suggests that the performance of 4D MRI in the
quadrant localization of PTA is improved with increasing size of the PTA. Further
studies, with preferably larger sample size, are needed to determine the cut off diameter
of the PTA at which the 4D MRI may become less sensitive as well as determine other
factors that may affect the accuracy of the 4D MRI in the diagnosis and quadrant
localization of PTA.

P 28. THE EFFECT OF ARCHITECTURAL DESIGN ON THE INCIDENCE
OF HOSPITAL WIDE DELIRIUM
AD Lynn MD, PhD; NR Lamborn MD; HW Hollis, Jr, MD
Denver, CO
Background: Delirium is a significant problem in medical and surgical patients
resulting in prolonged length of stay, escalation to higher levels of care and increased
use of skilled facilities following discharge. Medications and physiologic abnormalities
associated with patient illness are known to increase the risk of delirium. This report
seeks to evaluate hospital architectural design as a predisposing factor affecting rates
of delirium. The authors’ old hospital was built in 1961. Outdated infrastructure
mandated change achievable only by building an entirely new hospital, located one
block from the old site, that conformed to new building codes and safety standards.
It also provided an opportunity to investigate whether architectural design might
affect the incidence of delirium. The old hospital was designed with dual patient
rooms emanating radially from a central nursing station with poor noise control,
while the new hospital was designed with linear hallways, single patient rooms, and
minimal noise from work stations. This presents a unique opportunity to explore
how architecture may affect incidence of delirium in a relatively unchanged patient
population in the absence of significant hospital wide changes in delirium prevention
protocols or shifts in clinician staffing. The authors hypothesized that a change in
hospital architecture might facilitate a decrease in the incidence of delirium or improve
outcomes.
Method: A retrospective chart review was performed using an administrative database
of all hospitalized patients. We selected two calendar years remote from the year of
move for comparison. A total of 38,299 admissions occurred during the two years of
study. Of these patients, 1,033 were identified with the diagnosis of delirium by ICD9/10 codes. Among the patients with delirium, outcome variables included mortality,
length of stay (LOS), discharge level of care, and ICU LOS. Sample proportions were
compared using a two tailed z-test with significance designated at a p < 0.05. The study
was approved by SCL-Front Range IRB.
Results: There were no significant differences in age, gender or co-morbidities between
the cohorts examined. The overall incidence of delirium was significantly decreased
among patients after the move to the new hospital (3.43 %vs 1.99%, p< 0.001). Of the
patients who were diagnosed with delirium, the rate of in-hospital mortality in the old
hospital compared to new was 5.93 vs 6.51% respectively (p = 0.71), 30 day mortality
was 9.54 vs. 11.32%, respectively ( p=0.36) and overall LOS old to new was 9.2 days vs
8.2days ( p=0.18); these were not significantly different.
Conclusion: Noise levels, single patient rooms and access to nursing are all factors
that contribute to delirium. The linear hallway design of modern hospital construction
results in improvements in overall incidence of hospital-wide delirium. Within the
cohort of patients that experienced delirium, outcomes appear to be unaffected by
hospital architecture.

Ali, Lewis C. Lyons, Richard H. Turnage, Matthew R. Smeds
Little Rock, AR
Background: Previous studies have suggested patients undergoing midline abdominal
incisions for aneurysmal disease (AAA) have a higher rate of subsequent incisional
hernia formation than similar patients with aortoiliac occlusive disease (AIOD). We
sought to evaluate the rates of post-operative incisional hernia formation following
AIOD and AAA using either bilateral subcostal (BS) or midline (ML) and to determine
if there is a difference in these surgical approaches in subsequent hernia formation.
Method: Patients undergoing procedures for AAA or AIOD at a single institution
between January 2003 and December 2010 were reviewed (n = 447). Demographics,
intraoperative data, post-operative complications, imaging and follow-up data were
evaluated. All computed tomography (CT) performed after surgery was evaluated for
presence of hernia, and all follow-up notes were reviewed for presence of incisional
hernias on clinical exam.
Results: Over this time period, 171/447 (38%) patients had ML incisions, while
276/447 (62%) had BS incisions. CT was available for review in 200/447 (45%)
patients. 38/447 (8.5%) patients developed a hernia postoperatively with 12/171 (7%)
ML incision patients and 26/276 (9.4%) BS incision patients developing hernias (p =
.49). Only 20/38 (53%) patients with hernias were clinically evident, the remainder
being incidental findings on CT imaging. Patients with bilateral subcostal incisions
were more likely to have been treated for AAA (218/276 vs. 93/170, p = .0001),
have a smoking history (264/276 vs. 146/171, p = .03), have hypertension (235/276
vs. 130/171, p = .02) and hyperlipidemia (189/276 vs. 62/171, p = .0001), have a
perioperative wound complication (23/276 vs. 5/171, p = .03), and have a shorter
procedure time (200 minutes vs. 291 minutes). There was no difference in the risk of
hernia development according to incision type, aortic pathology treated (AIOD vs.
AAA), demographics, procedure time or estimated blood loss. Patients with hernias
were more likely to have a perioperative wound complication (11/38 vs. 18/409, p =
.0001) and higher BMI (28.7 vs. 25.3, p = .0007). 15/38 (40%) patients underwent
hernia repair at a median of 448 days post index procedure.
Conclusion: There is no difference in rates of hernia development when comparing
midline abdominal and bilateral subcostal incisions or aortic pathology being treated
(AIOD vs. AAA). Postoperative CT examination may identify an additional portion
of patients with incidental hernia formation, but the clinical relevance of this is not
determined, as in our series, these patients were all asymptomatic. Patients with
perioperative wound complications and increased BMI may be at increased risk of postoperative incisional hernia, regardless of incision type.

P 30. CARDIAC ARREST SECONDARY TO ACCIDENTAL HYPOTHERMIA:
DOES EXTRACORPOREAL BYPASS WORK?
Julia R. Coleman MD MPH, Clay Cothren Burlew MD, Ernest E. Moore MD,
Charles J. Fox MD, Eric M. Campion MD, Mitchel J. Cohen MD, Fredric M. Pieracci
MD
Denver, CO
Background: Accidental hypothermia is commonly encountered. Surgeons often
become involved when invasive warming techniques are necessary. The purpose of this
study is to evaluate rewarming techniques and outcomes for accidental hypothermia,
specifically patients who require extracorporeal bypass (ECB). We hypothesize: 1)
patients who require invasive techniques have a higher mortality rate, 2) ECB is a futile
intervention.
Method: All patients with a primary diagnosis of hypothermia (T<35°) from 20062015 were reviewed. Rewarming strategies included external (Bare hugger, blankets,
heating lamps), internal (warm fluids/bladder irrigation/chest lavage), Alsius catheter,
or ECB.
Results: During the study period, 238 adult patients were hypothermic, with
an average temperature of 31.0o. Of those evaluated, 79 (33%) patients (average
temperature 32.6o) were discharged from the ED after external warming techniques.
Of those admitted (159 patients, 82% men, mean age 55), rewarming techniques
included: 68 patients (43%) external warming, 48 (30%) internal warming, 29 (18%)
Alsius, 14 (9%) ECB. Patients undergoing ECB had a mean temperature of 23.8°, base
deficit of 16, and potassium of 4.4.
Conclusion: One-quarter of patients who present with accidental hypothermia require
invasive rewarming techniques. For patients with cardiac arrest, survival rates are
dismal but not 100%. There were no variables that determined survival following ECB.
Therefore, aggressive rewarming including ECB should be performed in hypothermic
arrest patients.

P 31. RADIOGRAPHIC VENTRAL HERNIAS ARE PREVALENT BEFORE
AND AFTER ABDOMINAL SURGERY
DV Cherla MD, ML Moses BS, KM Mueck MD, C Hannon, J Holihan MD, S Millas
MD, LS Kao MD, MK Liang MD, TC Ko MD
Houston, TX
Background: Increasing emphasis has been placed on the use of imaging such as CT
scan to identify and diagnose ventral hernias (VH) in patients. Our aims are to identify
the prevalence of radiographic VH among patients before and after abdominal surgery.
Method: An observational study of all patients undergoing abdominal surgery
for gastrointestinal cancer from 2011-2015 at a single institution was conducted.
Preoperative and postoperative CT scans were reviewed in a standardized manner for
presence of a VH as defined by the European Hernia Society: any abdominal wall gap
with or without a bulge.
Results: A total of 242/289 (83.7%) patients had both a preoperative (obtained a
median/range of 29/0-1886 days prior to surgery) and postoperative (obtained a
median/range of 448/2-2570 days following surgery) CT scan. Of the 242 included
patients, 149 (61.6%) had no prior abdominal surgeries while 93 (38.4%) had one or
more prior abdominal surgeries.
Among the patients with no prior abdominal surgery (n=149), the majority (n=87,
58.4%) had radiographic evidence of a primary VH. Following surgery, 24 (16.1%)
developed an incisional VH, 28 (18.8%) had evolution of their primary VH into a
larger incisional VH, 36 (24.2%) had no change in the appearance of their VH, and 21
(14.1%) had their primary VH repaired (overall, 59.1% had a VH on post-operative CT
scan; Figure 1).
Among the patients who had prior abdominal surgery (n=93), 58 (62.4%) had a
radiographic VH prior to their surgery for gastrointestinal cancer. Following surgery,
17 (18.3%) developed a new incisional VH, 30 (32.3%) had enlargement of their VH,
23 (24.7%) had no change in the appearance of their VH, and 5 (5.3%) had their VH
repaired (overall, 75.3% had a VH on post-operative CT scan; Figure 1).
Conclusion: The prevalence of radiographic VH among those before and after
abdominal surgery is high and increases with subsequent surgery. Presently, clinical
assessment and judgment remains the standard to diagnose VH. However, the clinical
significance of these radiographically-identified VH remains unknown.

P 33. TRENDS IN FEMORAL HERNIA REPAIRS PERFORMED FOR
RECURRENCE IN THE UNITED STATES
BL Murphy MD, DS Ubl, J Zhang MD, EB Habermann PhD, DR Farley MD, KH
Paley MD
Rochester, MN
Background: Nearly 30,000 femoral hernia repairs occur each year. As surgeons gain
more experience with laparoscopic groin hernia repair, one could hypothesize that
the rate of hernia recurrence would decrease over time. While inguinal hernia repair
recurrence rates are carefully scrutinized, the rate of femoral hernia recurrence has not
been reliably established in the United States. We sought to determine the trend of
femoral hernia repairs for recurrence over time.
Method: We identified all patients age≥ 18 who underwent femoral hernia repair from
three sources: the ACS National Surgical Quality Improvement Program (NSQIP)
database, providing data from 121 to 517 hospitals from 1/2005-12/2014, the Premier
database, which provides data from over 700 US hospitals from 1/2010-09/2015, and
an institutional database including the experience of three large academic sites from
1/2005-12/2014. In all patient populations, we identified the incidence of primary
and recurrent femoral hernia repairs stratified by gender. Trends were analyzed for a
decrease over time using a one-tailed Cochran-Armitage test.
Results: The three data sets contained 11,459 patients (75% female) undergoing
femoral hernia repair. In the NSQIP database, there were 6,649 femoral hernia repair
patients (73% female). In females the proportion of femoral hernia repairs done for
recurrence decreased over the study period: from 14.0% in 2005 to 6.2% in 2014
(p=0.02). In males there was no change over time: recurrences were 16.7% in 2005 and
16.1% in 2014 (p=0.18). The Premier database contained data on 4,495 (76% female)
femoral hernia repairs. In contrast to the NSQIP database there was no difference
for either gender. In females, 8.3% of repairs were performed for recurrence in 2010
and 4.7% in 2015 (p=0.10). In males, the rate was 22.6% in 2010 and 21.1% in 2015
(p=0.08). Within our institution 315 patients (67% female) underwent femoral hernia
repair during the study period. There was no difference for femoral hernia repairs over
time for either gender (p=0.20 for females and p=0.15 for males); however we were
underpowered as only 17 recurrent repairs occurred for females and 12 for males during
the study period.
Conclusion: Although our large multi-site institutional data base was too small from
which to draw conclusions, national databases show the proportion of femoral hernia
repairs performed for recurrence remained relatively constant in males and may be
decreasing in females in the United States between 2005 and 2015.

P 34. ROBOT-ASSISTED DIAPHRAGM PLICATION VIA AN ABDOMINAL
APPROACH
DA Hill MD, EY Kuo MD, SB Roy MD, P Kang MPH, T Ipsen MPH, C Haworth
MS, T Fey BAS, A Do BA
Phoenix, AZ
Background: Diaphragmatic paralysis, a known cause of dyspnea, can drastically
reduce breathing efficiency and result in decreased quality of life. Diaphragmatic
plication is the preferred surgical intervention for such patients. Here we report
our 3.5-year experience with 22 consecutive patients who underwent robot-assisted
diaphragmatic plication via an abdominal approach.
Method: We retrospectively reviewed records of 22 consecutive patients who
underwent robot-assisted diaphragmatic plication for diaphragmatic paralysis between
9/5/12 to 5/12/16. The primary outcome measure in this single-surgeon series was the
change in dyspnea severity. Dyspnea levels were measured with the Medical Research
Council (MRC) dyspnea scale, a 5-point scale with 5 describing the worst dyspnea (i.e.,
breathlessness so severe the individual is homebound). Univariate analysis via linear
regression was used to assess associations between demographic and clinical covariates
(e.g., length of stay, estimated blood loss, operation time). Multiple linear regression
models were adjusted for other covariates and baseline MRC scores.
Results: Of the 22 patients who underwent robotic diaphragmatic plication, 17
(77.3%) were male. Median body mass index was 30 + 4.8 kg/m2. Most procedures
(59%) were left-sided plications. One patient (4.6%) underwent bilateral plication.
Median operating time was 161+ 45 minutes, but the procedure was associated with
a steep learning curve. Median operating time for the first 3 procedures was 255 ± 27
minutes, but dropped to 151±44 minutes for remaining 19 cases. The median length of
stay was 3 days, and median time to chest tube removal was 1 day. Upon followup, 19
patients reported improved postoperative breathing, 2 patients reported no change, and
1 patient could not be reached. Preoperatively, the median MRC score in this cohort
was 4.0; this number dropped to a median of 2.2 postoperatively (p=0.001).
Conclusion: Transabdominal robotic diaphragmatic plication is an emerging
technique that offers attractive benefits, such as small incisions, improved surgical
dexterity, and a quick learning curve (approximately 3 to 4 cases). It can be easily
adopted with good OR times and early results have shown good functional outcomes.

P 36. SPLENIC INJURIES AFTER ERCP
MJ Yelenich-Huss MD, CJ Maki MD, F Nammour MD; M Ahmeti MD
Grand Forks, ND
Background: Endoscopic retrograde cholangiopancreatography (ERCP) is a common
technique for diagnosis and treatment in pancreatico-biliary disease, associated with a
complication rate of 5%-10% and a mortality rate of 0.5% (1). Common complications
include pancreatitis, gastrointestinal hemorrhage, intestinal perforation, and cholangitis
(2). Less common complications such as pneumothorax, hepatic hematoma, air emboli,
& portal vein/hepatic artery cannulation are also reported (1,3). Splenic injury due
to ERCP is extremely rare. We present 2 cases of patients requiring splenectomy after
ERCP
Method: Retrospective case series
Results: 1. A 76 y/o was admitted with obstructive choledocholithiasis, with exam and
labs consistent with diagnosis. Ultrasound (US) showed a dilated common bile duct
(CBD). ERCP showed multiple stones in the CBD, which were incompletely removed
after sphincterotomy and a stent was placed with difficulty. She then had symptomatic
bradycardia with hypotension. She was taken to the OR. With induction of general
anesthesia, the patient became quite hypotensive. Upon laparoscopically entering the
abdomen, about 1.5L of hemoperitoneum was noted, consisting of fresh and old blood.
The only abnormality found was an actively bleeding grade 2 inferior pole splenic
laceration, controlled with packing. Cholecystectomy was performed, but she had
refractory hypotension and a further 400mL of fresh blood was around the spleen.
Emergent splenectomy was performed. After she did well and discharged home.
2. A 57 y/o with was admitted with symptoms of obstructive choledocholithiasis and
consistent labs. US revealed dilated ducts. ERCP was performed; CBD cannulation was
difficult. Several hours later he developed refractory hypotension. He was transferred to
the ICU, transfused, and given vasopressors. Imaging showed active bleeding from the
spleen with hemoperitoneum. His status deteriorated and he was intubated.
Radiology performed splenic and short gastric artery embolization. His shock
state resolved. Exploratory laparotomy with evacuation of hemoperitoneum and
cholecystectomy were performed. Complete splenic avulsion was identified with 5L
of blood & ascites present. Splenectomy was performed. He did well and discharged
home.
Conclusion: Multiple reviews and single case reports have been published since
1988 detailing splenic injury after ERCP, but we are the only series with 2 patients
(1-9). Cases include splenic laceration, rupture, and avulsion of splenic vessels
(3). Mechanisms of splenic injury have been proposed as excessive traction of the
splenocolic/gastrosplenic ligament during the ERCP, adhesions causing decreased
mobility, and direct trauma (4, 5).
Complications after ERCP are uncommon, and splenic injuries leading to splenectomy
after ERCP represent an extremely rare subset. Procedural difficulty is the only
common theme we found. A hemoglobin drop or hemodynamic instability following
ERCP should raise suspicion for splenic injury and prompt rapid investigation

P 38. LAPAROSCOPIC VENTRAL HERNIA AND INGUINAL HERNIA
REPAIR USING ONLY TWO 5MM PORTS
Hugo Bonatti
Schwaz, Austria
Background: Most surgeons use one 10-12mm and two 5mm trocars for laparoscopic
repair of abdominal hernias. Attempts to further miniaturize and reduce surgical
trauma include SILS and use of micro instruments amongst others.
Method: All patients undergoing laparoscopic ventral and inguinal hernia repair by a
single surgeon were reviewed and patients who had the procedure done with only two
5mm trocars were investigated in detail. For inguinal hernias and a subset of ventral
hernias the Teleflex mini-grasper, a 2.3mm needle grasper that is introduced without
trocar was used as an additional instrument. The MESH was introduced into the
abdomen through a port site after removal of the trocar. For fascia closure and fixation
of the MESH in ventral hernias a suture passer was used.
Results: A total of 14 patients were identified who had their hernias repaired with
only two 5mm trocars. In five patients with inguinal hernias and in two patients
with Spigelian hernias, the Teleflex mini-grasper was used and all patients had a
transabdominal preperitoneal repair (TAPP) with use of a ProGrip self fixating MESH
without tacks. For the TAPP inguinal hernia repair, the peritoneal flaps were created
from a vertical incision between the umbilicus and the bladder dome. For the Spigelian
hernias the flap was created from an incision at the dome of the reduced hernia sack.
The peritoneum was re-approximated with a running 3-0 silk suture or a V-lock suture
using the mini-grasper instead of a Maryland. For one small Spigelian hernia and
umbilical and epigastric hernias, a suture passer was used to close the hernia defect and
a 9cm coated MESH was used for reinforcement. Median age of the eleven men and
three women was 73 (range 23-88) years. The patients tolerated the hernia repair well
and was done in six patients as an outpatient procedure and eight patients were placed
in extended recovery or remained admitted.
Conclusion: This pilot study shows that abdominal hernia repair using only two 5 mm
trocars is feasible in many patients and well accepted. The Teleflex mini-grasper can
completely replace a laparoscopic grasping instrument.

P 39. USE OF LIGHTED URETERAL STENTS IN LAPAROSCOPIC COLON
SURGERY
Hugo Bonatti
Schwaz, Austria
Background: Injury to the ureter is one of the most feared complications in surgery
for left colonic, sigmoid, rectal pathologies especially in patients with inflammatory
disease involving the left pelvic wall. Ureteral stents have been used in previous series
and whereas detection of ureter leaks was reported to be better, conflicting data on
prevention of this severe complication have been published. Lighted stents have been in
use for several years now but there remains paucity on data. This has multiple reasons
one of them is availability of a urologist willing to place such a stent prior to colonic
surgery.
Method: All patients from a single rural hospital who had colonic resection and had
a lighted ureteral stent placed cystoscopically prior to the procedure during a two
years period were included in this study. The stent was removed immediately after the
procedure, a Foley catheter remained in place for 24-48 hours per protocol.
Results: A total of 18 patients including 10 men and 8 women with a median age of
62.4 (range 28.0 - 88.5) years were identified. Cystoscopic placement of the ureteral
stent was successful in all cases and took average less than 30 minutes. In 17 cases the
stent was placed in the left ureter with fifteen patients having a laparoscopic sigmoid
colectomy/low anterior resection. Two patients had a laparoscopic Hartman reversal.
Only one patient who had a right hemicolectomy after previous pelvic surgery had a
right lighted ureteral stent provided. In all cases the lighted stent was well visualized
(figure 1) allowing safe dissection of tissue far away from the critical structure and in no
case an injury to the ureter or bladder occurred. Macrohematuria was observed in the
majority of patients but no patient suffered ureter injury or kidney injury.
Conclusion: Lighted ureteal stents were found extremely useful in laparoscopic colon
surgery with risk of ureter injury. This is not only a matter of patient safety but also
allows much faster dissection of tissue and potentially shortens the surgical procedure.
Based on the data of our pilot study, lighted stents placement has become standard at
our hospital. These stents may be particularly useful in the rural setting.

P 40. PATIENT OUTCOMES FOLLOWING ROUX-EN-Y GASTRIC BYPASS
REVERSAL
PE Ernest MD, FA Husain MD, BJ Pottorf MD, HW Hollis MD
Denver, CO
Background: Roux-en-Y gastric bypass (RYGB) continues to be one of the most
common surgical weight loss procedures performed in the US. Complications
can occur early in the postoperative period or years following operation. Longterm complications include: malnutrition/failure to thrive, hyperinsulinemic
hypoglycemia, recurrent marginal ulcer, and recalcitrant hypocalcemia associated
with hypoparathyroidism. Medical management alone is not always successful.
Occasionally, restoration of normal anatomic physiology (RYGB reversal) is required
to meliorate symptoms and untoward metabolic consequences. To avoid weight regain,
given the chronicity of obesity as a disease, reversal can be done with conversion to
sleeve gastrectomy. This study was designed to analyze the results of patients requiring
reversal of their RYGB with and without conversion to sleeve gastrectomy.
Method: Procedures were performed by a formally trained bariatric surgeon. Data
was analyzed after retrospective chart review. Analysis of demographics, pre and
post-operative Body Mass Index (BMI), comorbidities, and outcomes accompany this
review.
Results: From November 2012 to June 2014, 14 patients (3 male, 11 female)
required laparoscopic reversal of their RYGB to normal anatomy, and 3 included
concomitant revision to sleeve gastrectomy. Complications mandating reversal
included refractory neuroglycopenia (n=4), malnutrition/failure to thrive (n=7),
persistent hemorrhaging from marginal ulcer (n=2), and chronic abdominal pain
(n=1). Patients diagnosed with neuroglycopenia received a complete workup and
medical optimization from an endocrinologist prior to operation. Patients with
malnutrition/failure to thrive, marginal ulcer, and chronic abdominal pain underwent
an esophagogastroduodenoscopy (EGD) before operation and were optimized
nonoperatively. Prior to reversal, the mean BMI was 29.1 kg/m2 (18.5-42.6 kg/m2).
Post reversal the mean BMI increased to 32.9kg/m2 (24-42.7kg/m2). Patients reversed
for hyperinsulinemic hypoglycemia showed the greatest weight gain with a BMI
increase of 6 versus 3.28 for the rest of the study group. Postoperative complications
included anastomotic leak requiring reoperation (n=1), superficial port site infection
(n=1), and chronic pain (n=2). Average hospital stay was 3 days. Two patients were lost
to follow-up. All but one patient had resolution of their symptoms at two years post
procedure. Two additional patients sustained unwanted weight gain and underwent
laparoscopic sleeve gastrectomy within one-year of reversal.
Conclusion: Laparoscopic reversal of RYGB with or without sleeve gastrectomy
may alleviate most chronic complications of a RYGB. Weight gain can be expected
after reversal of RYGB alone, and even with adjunctive sleeve gastrectomy. Weight
gain following intervention was greatest among those patients reversed for refractory
hyperinsulinemic hypoglycemia demonstrating that medical and behavioral
optimization of these patients is important prior to considering surgical reversal.

P 41. FEMALE VERSUS MALE MORBIDLY OBESE SURGICAL
PATIENTS VARY SIGNIFICANTLY IN PRE-OPERATIVE CLINICAL
CHARACTERISTCS: ANALYSIS OF 67,514 BARIATRIC SURGERY WOMEN
AND MEN
CM Bashian, DO, GJ Slotman, MD
Vineland, NJ
Background: While more women than men undergo bariatric surgery, differences
between the sexes in obesity-related pre-operative clinical conditions have not been
investigated. The objective of this study was to identify variations in age, BMI, and the
incidence of obesity co-morbidities between morbidly obese women and men.
Method: Pre-operative clinical data on 53,292 women and 14, 222 men in the Surgical
Review Corporation’s BOLD database who underwent adjustable gastric band (AGB)
was examined retrospectively. Female versus male age and BMI, race, insurance, and
the frequency of major obesity co-morbidities were compared by analysis of variance
and the Chi-squared equation.
Results: Female/male age (45.2+-12/48.2+-12; p<0.001), BMI (44.6+-7/46.2+-7;
p<0.0001), race (African-American 12.4%/6.8%, Caucasian 73.5%/78.3%, p<0.001),
and health insurance (Medicaid 3.1%/1.6%, Medicare 7.1%/9.9%; p<0.0001) varied
significantly. Obesity co-morbidities (%) are detailed in the Table. Overall, females
carried 12 weight-related illnesses more frequently than did males (abdominal
panniculitis, cholelithiasis, GERD, stress urinary incontinence, asthma, back
pain, fibromyalgia, pseudotumor cerebri, mental health diagnosis, depression, and
psychological impairment - p<0.0001 - and lower extremity edema - p<0.01). Males
had higher incidences of 18 obesity co-morbidities, compared with females (abdominal
hernia, liver disease, obesity hypoventilation syndrome, obstructive sleep apnea, angina,
hypertension, CHF, ischemic heart disease, peripheral vascular disease, dyslipidemia,
diabetes, gout, impaired functional status, alcohol use, tobacco use, substance abuse,
and unemployment - p<0.0001 - and DVT-PE - p<0.01). Pulmonary hypertension and
musculoskeletal pain did not vary female/male.
Conclusion: The pre-operative clinical characteristics of morbidy obese women and
men varied significantly. Women were more frequently African-American and on
Medicaid while men were more often Caucasian and on Medicare. Before AGB,
compared with women, men were older, had higher BMI, used alcohol, drugs, and
tobacco more frequently, and had higher rates of cardiovascular pathology, obesity
hypoventilation syndrome and obstructive sleep apnea, diabetes, gout, abdominal
hernia, liver disease, and impaired functional status. Among women, asthma,
cholelithiasis, stress urinary incontinence, abdominal panniculitis, and mental health
issues/dysfunction were more frequent than for men. These findings could aid care of
AGB patients. Although AGB patients were self-selected, significant variations by sex
can be applied to other obese individuals. Since all surgeons now operate on morbidly
obese patients, the advance clinical knowledge reported here can increase clinical
acumen and may facilitate anticipatory management. Understanding the weight-related
characteristics of obese men and women thus may improve outcomes for all procedures
that must be performed on the morbidly obese.

A Berens RD, A Lieberman PhD, JL Johnson MD, FM Pieracci MD MPH
Aurora, CO
Background: Laparoscopic sleeve gastrectomy (LSG) is an increasingly utilized
bariatric operation, with large studies reporting similar and sustained weight loss,
resolution of comorbidities, and decreased peri-operative morbidity as compared
to laparoscopic Roux-en-Y gastric bypass (LGB). The purpose of this study was to
evaluate our initial experience with LSG performed by general and acute care surgeons
in a safety net hospital. We hypothesized that weight loss outcomes were comparable
between LSG and LGB.
Method: We retrospectively reviewed the first 15 patients who underwent LSG at our
safety net hospital and compared them to 15 patients who underwent LGB during the
same time period. All surgeries were performed by two general/acute care surgeons.
The primary outcome was a decrease in body mass index (BMI) at 1 year after surgery.
Outcomes were compared with Student’s t-test or chi-square test using SPSS.
Results: A total of 30 patients underwent either LGB or LSG (15 each) during the
study period. Within this population, 70% patients had hypertension, 27% had
dyslipidemia, 40% had type 2 diabetes mellitus, 26.7% obstructive sleep apnea
with half of those requiring continuous positive pressure airway pressure, and 47%
had gastroesophageal reflux disease symptoms. There was no difference in baseline
characteristics between two groups, including age, gender, and cardiometabolic
comorbidities. Outcomes are summarized in the Table. Weight loss after LSG at 1 year
after surgery was similar to LGB [82.9 lbs (32.4%) vs. 81.7lbs (28.3%), p= 0.93]. The
mean BMI decrease was 14.4 (LSG) vs 11.9 (LGB), p=0.14. A total of 72% patients
went off anti-hypertensive medications at 1 year with the mean decrease of the MAP by
10.8% in LSG compared to 10.6% LGB group. Hospital length of stay (LOS) for LGB
was 6.3 days compared to 2.67 days in LSG (p=0.332). Number of readmissions were
higher in LGB compared to LSG group (40% vs 6.7%, p=0.03).
Conclusion: In our safety net system, LSG resulted in equivalent weight loss at 1
year with good clinical outcomes and improvement in cardiometabolic comorbidities,
shorter length of stay, and decreased hospital re-admissions as compared to LGB. Long
term outcomes are needed to fully evaluate the efficacy of this operation.

P 43. LAPAROSCOPIC ROUX-EN-Y GASTRIC BYPASS VERSUS SLEEVE
GASTRECTOMY: 3-YEAR OUTCOMES
EE Nearing II MD, AJ Borgert PhD, KJ Kallies MS, MT Baker MD, BT Grover DO,
SN Kothari MD
La Crosse, WI
Background: Laparoscopic Roux-en-Y gastric bypass (LRYGB) is a well-established
procedure for the surgical treatment of obesity. In the past 5 years, laparoscopic sleeve
gastrectomy (LSG) has increased in popularity, with case volumes doubling according
to recent estimates. Data comparing these two procedures are limited. The objective of
this study was to compare weight loss and comorbidity improvement for LRYGB versus
LSG over a 3-year follow-up period.
Method: A retrospective review of our institution’s prospective bariatric surgery
registry and integrated multispecialty health system electronic medical record system
was completed. Patients who underwent LRYGB or LSG from 2010-2015 were
included. Comorbidity status was defined according to 2015 Standards for Outcome
Reporting. Statistical analysis included chi-square test. A P value <0.05 was considered
significant.
Results: During the study period, 539 patients underwent LRYGB and 201 underwent
LSG. The mean preoperative BMI was 47.0 ± 6.5 in the LRYGB group vs. 45.3 ± 5.3
in the LSG group (P=0.002). Mean follow-up was 2.6 ± 1.5 years in the LRYGB group
and 1.6 ± 1.2 years in the LSG group (P<0.001), with 1, 2, and 3-year follow-up rates
of 78%, 51% and 44% for LRYGB and 68% 27%, and 19% for LSG, respectively.
Thirty-day complications in the LRYGB vs. LSG groups included anastomotic/
staple line leak (0.2% vs. 0; P=0.990), venous thromboembolism (0.6% vs. 0.5%;
P=0.990), bleed requiring transfusion (0.7% vs. 0; P=0.570), surgical site infections
(0.7% vs. 0; P=0.580), and urinary tract infection (1.1% vs. 0.5%; P=0.680). There
was one conversion to open in the LRYGB group. There were no 30-day mortalities.
Preoperatively, type II diabetes (T2DM) was observed in 185 (34%) and 35 (17%)
LRYGB and LSG patients, respectively; dyslipidemia in 310 (58%) LRYGB patients vs.
88 (44%) LSG patients; and hypertension in 451 (84%) and 154 (77%) LRYGB and
LSG patients, respectively.
Conclusion: Case volumes and popularity for LGS are increasing, however long term
data is limited. In comparison to LSG, LRYGB results in increased excess weight
loss with similar improvements in patient comorbidities. There was no difference in
complication rates between the two procedures. The long-term durability of LSG
outcomes has yet to be fully elucidated; however, intermediate evaluation suggests that
LSG is a safe and comparable alternative to LRYGB.

P 44. INITIAL ROBOTIC EXPERIENCE IN COMBINED RECURRENT
UMBILICAL HERNIA AND DIASTASIS RECTI REPAIR
D Vargo MD
Salt Lake City, UT
Background: Umbilical hernia repair is typically quoted as having a high success
rate, with recent 5 year data showing a 6.3% recurrence rate in primary repair and no
recurrences in mesh repair. However, there is a sub-population of patients with diastasis
recti who do have a higher rate of recurrence. Recent literature, however, showed a 31%
recurrence rate in patients with diastasis recti compared to to 8% without diastasis.
Hypothesis is that repair of the diastasis at the time of umbilical hernia repair will
decrease the recurrence rate.
Method: A case series utilizing prospectively collected data at a single institution was
evaluated for short term outcomes in robotic repair of upper abdominal diastasis in
conjunction with recurrent umbilical hernia repair. Biographical data, co-morbidities,
operative technique, and post-operative outcomes were evaluated. Primary outcome
measure was wound complication and early hernia recurrence.
Results: 10 patients with recurrent hernia and associated diastasis were evaluated over
a ten month period from August 2015 through June 2016 . Average time to recurrence
from initial operation was 13.8 months (range 5-37 months). 10% of patients had a
wound complication after the initial procedure. Diastasis was diagnosed by physical
exam +/- CT scan. Secondary procedures were all performed robotically, with the
upper midline diastasis being closed primarily, along with the umbilical defect, and
mesh being implanted for just the umbilical defect. Average follow up was 248 days
(range 100-397 days). There was one early hernia recurrence, the first case in the series,
that was thought to be due to a technical error. The remaining 9 patients have intact
repairs. There was one small skin separation at a trocar site. No other wound issues were
identified.
Conclusion: Robotic repair of diastasis recti in association with recurrent umbilical
hernia repair is a safe operation with good short term outcomes. Results point to a
possible need to stratify patients with umbilical hernia into different categories that
require different operative approaches.

P 45. THE EFFECTS OF OPERATING ROOM RESTRUCTURING ON
QUALITY OF SURGICAL CARE FOR BENIGN BILIARY DISEASE AT A
SAFETY-NET HOSPITAL
KM Mueck MD MPH, S Wei MD, CJ Wray MD, MK Liang MD, LS Kao MD MS,
TC Ko MD
Houston, TX
Background: Limited access to cholecystectomy for benign biliary disease has been
associated with worsened care in at least 3 of the 6 domains of quality: timeliness
(avoidance of delays), efficiency (limited waste of resources), and safety (complications).
Prior study of cholecystectomies at our safety-net hospital demonstrated that
the majority of patients received non-elective surgery. Of these patients, 30%
underwent nighttime surgery which was associated with a small but increased risk
of complications. We hypothesized that operating room restructuring by opening an
ambulatory outpatient center (OC) and dedicating daytime operating rooms for urgent
and emergent cases (acute care surgery or ACS rooms) would increase timeliness and
efficiency of surgical care and improve patient safety.
Method: A retrospective single-center analysis was performed of patients undergoing
elective laparoscopic cholecystectomy at a safety-net hospital before (October 2010May2011) and after opening of an OC (October 2014-May 2015), as well as before
and after (March-August 2016) opening of ACS rooms. Data were collected on
demographics, diagnosis, emergency room and clinic visits, imaging tests, time to
surgery, length of stay (LOS), and 30-day complications (surgical site infections, bile
leak, retained stone, bile duct injury, pneumonia). Univariate analyses were performed
using chi-square and Kruskal-Wallis tests (STATA).
Results: A total of 1826 cholecystectomies were performed over the 3 periods. The
number of both elective and non-elective cholecystectomies performed per month
increased significantly over the three time periods (Table 1). Patients were older in the
later periods, but were otherwise similar in sex, race/ethnicity, and body mass index.
Among patients undergoing elective cholecystectomy, the median time from first
surgery clinic visit to surgery and from diagnosis of benign biliary disease to surgery
decreased significantly. Despite increased timeliness, patients had more imaging
and emergency room visits prior to surgery. There were no significant differences in
complications or readmissions. Among patients undergoing non-elective surgery, after
the addition of daytime ACS rooms, the proportion of patients undergoing nighttime
surgery paradoxically increased.
Conclusion: Operating room restructuring at a safety-net hospital did not improve
overall quality of surgical care for benign biliary disease. The opening of an outpatient
center was associated with a greater number of elective cholecystectomies per month
being performed and a shorter time from initial diagnosis and first clinic visit to
surgery. However, addition of daytime acute care surgery rooms was associated with
a paradoxical increase in nighttime cholecystectomies and greater resource utilization
prior to surgery. Additional strategies to improve the quality of care should focus on
further improving access to and timeliness of surgical consultation for underserved
patients.

P 47. DECREASING TRANSFERS TO HIGHER LEVEL OF CARE
FOLLOWING TRANSFERS OUT OF THE ICU
S McAllister RN MSN, GT Tominaga MD, J Darnell BSN, Z Mayors RN BSN, DS
McCaul, MD
La Jolla, CA
Background: This study was undertaken to determine whether close follow-up by a
trained RN on emergency standardized procedures could decrease transfer to a higher
level of care in patients recently transferred out of the ICU.
Method: Patients transferred from the ICU to the step-down unit, telemetry or
ward in one regional community hospital that is a designated ACS-COT Level
II Trauma Center, certified stroke center, and regional Cardiology Institute were
studied. Designated Critical Care nurses (Code RN) that respond to all in-hospital
code blues and Rapid Response Team activation underwent training on emergency
standardized procedures. This includes basic management in acute changes in heart
rate or symptomatic hypotension, chest pain, acute mental status change, airway
compromise, anaphylaxis, seizure, medication inducted respiratory depression,
suspected sepsis, and emergency cardiac management. Beginning September 1, 2015,
the Code RN was dedicated to rounding on all patients discharged from the ICU
within the past 24 hours and attend all the Rapid Response Team activations. We
compared data from 2014 (A -pre-implementation) to Jan through September 2016 (B
-post-implementation). Demographic data, RN interventions and outcome data were
collected. Transfer back to the ICU or higher level of care was the outcome variable
studied.
Results: Similar number of RN interventions were performed during each time but the
procedures performed during the post-implementation were standardized. The most
common problems encountered were related to airway problems and changes in heart
rate or blood pressure. Mean age was similar in each group. Significantly more patients
did not require transfer to a higher level of care during the Post Implementation group
(51.6% versus 40.3%, p=0.0107). There was a trend toward decreased mortality in the
Post Implementation group (p=0.063). See table.
Conclusion: We found a decrease in transfers to higher level of care in patients recently
transferred out of the ICU that were evaluated by a Critical Care nurse trained in basic
standardized procedures.

P 48. STANDARDIZING HANDOFFS BETWEEN OPERATING ROOM
AND SURGICAL INTENSIVE CARE UNIT IMPROVES INFORMATION
EXCHANGE
D Mukhopadhyay MD, KC Wiggins-Dohlvik MD, MM MrDutt MD, JS Hamaker
MD, GL Machen MD, ML Davis MD, JL Regner MD, RW Smith MD, DP Ciceri
MD, JG Shake MD
Temple, TX
Background: The transfer of critically ill patients from the operating room (OR)
directly to the surgical intensive care unit (SICU) involves handoffs between multiple
care providers of various specialties. Incomplete handoffs lead to poor communication,
which is a major contributor to sentinel events resulting in medical error and patient
death. The aim of the study was to identify areas of improvement in the current method
of patient handoffs at our institution, standardize the process, and determine whether
this led to improvements in caregiver involvement and information omissions.
Method: A prospective intervention study was designed to observe the process
surrounding patient transfer from OR to SICU at Scott & White Memorial hospital,
a 635 bed tertiary care academic center in a semi-rural setting. Over a two month
period, thirty one patient handoffs from the OR to SICU were observed for 49 critical
parameters including caregiver presence, pre-operative and intra-operative details, and
time required to complete key steps. Over the following six months, a standardized
protocol was implemented and all caregiver groups educated regarding the new
protocol. Thirty one follow-up handoffs were then observed over two months to
determine whether there was an improvement in caregiver involvement and reduction
in information omission.
Results: Standardization led to a significant improvement in presence of an ICU
physician provider as well as a member of the surgical team during the bedside handoff
and transfer (p=0.0004 and p<0.0001, respectively). Resultantly, there was an overall
improvement in information omissions in both the surgical report, e.g. identification
of the procedure performed (p=0.0048), operative complications (p<0.0001), and
surgical concerns (p<0.0001), and the anesthesia report, including easy of laryngoscopy
(p<0.0001), ventilator settings (p<0.0001) and pressor requirements (p=0.0134).
Protocolization also led to an average decrease in time required for physical transfer
to the ICU monitor by 27 seconds (p=0.11) and the ventilator by 12 seconds (p=0.58)
while only increasing time required for handoff from 5:37 to 6:16 (p=0.22), which was
not statistically significant.
Conclusion: Implementation of a standardized handoff protocol when transferring
patients from the OR to the SICU led to a significant improvement in caregiver
involvement and reduction in information omission without a drastic increase in time
commitment of involved providers.

P 49. A THREE PRONGED APPROACH FOR PRACTICE-BASED LEARNING
AND QUALITY OF CARE IMPROVEMENT IN A SURGICAL RESIDENCY
PROGRAM.
KM Rose MD, LA Steber PA, DJ Johnson MD, AB Chapital MD PhD
Phoenix, AZ
Background: The value of morbidity and mortality conference (M&M) has been well
established in the surgical literature. Traditionally, M&M relies on voluntary selfreported retrospective data, which may preclude a consistent analysis for improvement
in patient care. Recently, the popularization of systems-based responsibility for patient
outcomes such as the American College of Surgeons National Surgical Quality
Improvement Program (NSQIP) has led some departments to abandon the traditional
M&M conference. Our surgical department sought to improve the collection, analysis,
and reporting of adverse events by integrating a new systems-based practice approach
that focuses on patient care, resident education, and systems issues.
Method: Beginning July 1st, 2016, our institution has progressively refurbished M&M
conferences in three distinct ways. First, we prospectively define and collect daily
complications, readmissions, and returns to the operating room daily with the Chair
of Surgery and Hospital Medical Director. Second, we participate and engage in a
weekly department-wide M&M conference with residents, attending physicians, and
allied health staff. During this time, residents or fellows present patient information
in an anonymous, case-based format open to any questions, concerns, or suggestions.
Representatives from other departments such as transplant surgery, plastic surgery,
etc., are invited to attend and present in a collaborative effort. Readmissions and
reoperations from the previous week are addressed at this time. Third, patient safety
incidents are reported with quality personnel, nursing, and attending physician
presence. Issues and solutions are recorded and presented to department personnel to
address policy change for improved patient care. We then compared our institution’s
current academic year data to previous year’s to better understand the impact of
reshaping our M&M conference.
Results: Since the initiation of the three-pronged approach, our surgical department’s
M&M has recorded improved attendance, resident satisfaction, increased discovery
of events, opportunities to affect patient care during prospective collection, and
resident reflection on care in an open forum. During the 2015-2016 academic year,
65 patient cases were presented at the General Surgery M&M Conference. Following
the structural change and implementation of the three-pronged approach, we have
presented 36 cases in the first quarter of the 2016-17 academic year alone, projecting
to an annualized total of 108 cases with continued implementation. Additionally, our
discussion of hospital safety issues has led to hospital wide policy changes to improve
patient safety and monitoring.
Conclusion: Our surgical department believes this three-pronged model provides
an avenue for shared learning and best practices, monitoring of safety and regulatory
issues, and an opportunity for staff and resident physicians to directly contribute to
system improvements.

P 50. HEALTH LITERACY DISPARITIES AMONG TRAUMA PATIENTS: A
TARGET OF OPPORTUNITY
JL Dameworth MD, JA Weinberg MD, PW Goslar PhD, TM Thompson MA, NV
Peters, DJ Stout RN, SR Petersen MD
Phoenix, AZ
Background: Low functional health literacy (HL) can complicate physician-patient
communication, compromise care, and is associated with worse outcomes. Disparities
in HL have been observed with respect to race/ethnicity and socioeconomic status.
Although HL has been studied in diverse patient populations, relatively little attention
has been given to this issue in trauma patients. To date, trauma patient HL has not
been assessed with a validated instrument. The purpose of this study was to assess the
prevalence of low HL with a validated assessment tool among hospitalized trauma
patients, and to determine patient characteristics that are associated with low HL.
Method: A convenience sample of adult patients admitted to an urban, ACS level 1
trauma center completed the Short Assessment of Health Literacy (SAHL) assessment
prior to hospital discharge over a six-month period. This validated test involves a
standardized 2-3 minute interview at bedside. Patient’s medical decision maker
(MDM) was interviewed in setting of cognitive impairment. Demographic and clinical
data were prospectively collected, including age, gender, race/ethnicity, injury severity,
and self-reported level of education. In addition, the Community Need Index (CNI),
which stratifies community health need by zip code, was recorded for each patient.
Results: 128 adult trauma patients (with 17 MDM) completed the SAHL. Average
patient age was 44, 33% female, and median ISS 10. 31 patients (24.2%) had low HL
by SAHL result. Low HL was associated with education level (high school or less: 32%
vs. college: 12%; p = 0.009), self-opinion of knowledge of medical terms (NO: 35%
vs. YES: 16%; p = 0.017), and CNI (High CNI: 29% vs. Low CNI: 8%; p = 0.025). In
addition, white non-Hispanic patients were significantly more likely to have adequate
HL than all others (Figure, p = 0.007).
Conclusion: Low HL is prevalent among hospitalized trauma patients. Similar to prior
studies concerning non-trauma patient populations, significant HL disparities were
associated with education level, community health need, and race/ethnicity. Bedside
assessment of HL is relatively easy to perform, is associated with disparities known to
affect outcomes, and allows opportunity for targeted interventions that may improve
both provider-patient communication and quality of care.

P 51. MANAGING BARRIERS TO RECYCLING IN THE OPERATING ROOM
Solomon Azouz M.D. M.Sc., Nikki Castel M.D., Terry Maffi M.D., Piper Boyll B.Sc.,
Alanna Rebecca M.D. MBA
Phoenix, AZ
Background: Operating rooms contribute to the ever-increasing volumes and costs
of hospital waste. Little is known concerning barriers to recycling and perception of
hospital waste, despite continued improvement in recycling programs. The estimated
amount of waste produced per hospital bed per day varies from 0.2kg to 33kg.
Approximately 75% to 90% of this is considered general waste, with the remainder
being hazardous waste which must be transported and disposed of by specialized
means. Waste production can be minimized by four means: (1) source reduction,
(2) management and control measures that guide hospital product use, (3) waste
segregation before disposal and (4) recycling or reuse of products. The operating room
contributes approximately 20-33% of total healthcare waste, which can be quite costly
to dispose of. General waste disposal costs $0.03-0.08/lb, regulated medical waste
$0.20-0.50/lb, hazardous waste $1.70-2.00/lb, and universal waste $0.75-1.00/lb.
However, the disposal of recyclables costs only $0.01/lb. Proper disposal of appropriate
recyclable materials in the OR could drastically reduce unnecessary costs and wasted
healthcare dollars.
Method: A survey of operative personnel was performed in order to identify any
potential barriers to recycling. Questions addressed knowledge of recyclable materials
and improvement strategies. The survey design was validated using pretesting and
clinical sensibility testing. The survey took approximately 5-10 minutes to complete,
and consisted of 22 questions. Data was anonymous and subjects were permitted to
opt-out of the survey if they desired. These data facilitated the creation of a recycling
program.
Results: Over four hundred completed the survey. Most respondents reported having a
positive attitude toward recycling, and were active recyclers in their homes. According
to our survey, 75.4% of participants responded that it is unclear what waste items are
recyclable, and 50% of participants reported that they never recycle or only sometimes
recycle in the OR. The results revealed a general misunderstanding regarding proper
recycling techniques, but not a lack of willingness to recycle. The majority supported
greater operating room waste recycling, and thought indefinable barriers included
labeling and training. These data facilitated the creation of labeling and directed
education to proper disposal of waste.
Conclusion: Recycling is an important component of dealing with operating room
waste, and is critical in lowering disposal costs. Despite an active recycling program,
the majority of respondents reported that improvements could be made in recycling
education and availability in the operating room. Optimizing how recycling is
managed in operating rooms requires building a framework that improves knowledge,
training, and availability.

P 52. IMPLEMENTATION OF AN ERAS PROTOCOL FOR COLECTOMY IS
ASSOCIATED WITH IMPRESSIVE RESULTS
I Van Dyken MD, S Nishida MD, L Kanai MD, K Mah MD, GX Zhang, PhD, WL
Biffl MD
Honolulu, HI
Background: Enhanced recovery after surgery (ERAS) protocols have been
implemented around the world, for numerous types of abdominal surgery, with good
clinical outcomes and patient satisfaction. For unclear reasons- perhaps because the
published protocols appear daunting- they have not been embraced broadly in the U.S.
In our institution, we see a great deal of variation in colorectal surgery, and it continues
to be the highest risk procedure for surgical site infections (SSIs). We hypothesized that
implementation of an ERAS protocol would improve hospital length of stay and reduce
surgical site infections following colorectal surgery.
Method: A protocol focusing on preoperative (bowel preparation, showering),
intraoperative (non-narcotic adjuncts for analgesia, judicious fluid administration),
and postoperative (early diet and ambulation) factors was implemented in June 2015.
Patient expectations were focused on early diet, mobility, and discharge. Cases were
reviewed, along with non-ERAS controls during the same time period. Outcomes
were compared by Wilcoxon tests for continuous variables and Fisher’s exact tests for
categorical variables (*=p<0.05).
Results: ERAS (n=30) patients had shorter median hospital length of stay (LOS) than
non-ERAS (n=116) patients (3.4 vs 6.0 days*). Median time to ambulation (0.5 vs 0.9
days*) and from surgery to discharge (3.0 vs 4.8 days*) were also shorter. The ERAS
group had nonstatistically-significant reductions in SSIs (0 vs 6%), mortality (0 vs 3%)
and 30-day readmission (3% vs 5%).
Conclusion: Implementation of the modified ERAS protocol was straightforward and
led to substantial reduction in both hospital and postoperative length of stay. ERAS
also may help to reduce surgical site infections. There does not seem to be any downside
to implementing such a protocol universally.

P 53. IMPACT OF SURGICAL FELLOWSHIPS ON AMERICAN BOARD OF
SURGERY PASS RATES FOR GENERAL SURGERY PROGRAMS
MJ Al Fayyadh MBChB, C Foote MS, JA Rawlings BS, B Bankhead-Kendall MD, M
Truitt MD, JW Kempenich MD, RE Willis PhD, DL Dent MD
San Antonio, TX
Background: Fellowship programs may result in lost case volume and variety for
residents operating as primary surgeons. We hypothesized that the increased number
of fellows would lead to lower pass rates on American Board of Surgery (ABS)
Examinations.
Method: Retrospective review of publicly available five-year rolling pass rate for first
time examinees on ABS Qualifying Exam (QE), Certifying Exam (CE) and QE/CE
index from 2010-2015 was performed. Surgical fellow positions for 2015 were examined
by specialty. Pass rates were compared between general surgery residents who trained
with fellows and without fellows. Fellow to resident ratio was calculated by dividing
the number of fellows over the number of approved general surgery PGY5 categorical
positions. We further categorized the programs based on fellow to resident ratio. We
defined high fellow to resident ratio as greater than 0.5 and low resident to fellow ratio
as lower than 0.5. Statistical analysis was performed using Fisher’s exact test with α±
<0.05.
Results: Of the 242 programs, 148 had fellows. General surgery residents who trained
with fellows had higher pass rates than without fellows on QE (88% vs 86%), CE
(83% vs 80%) and combined QE/CE (74% vs 69%; p<0.05). Pass rates were also
higher for residents who trained with fellows in all QE, CE, and QE/CE for vascular,
cardiothoracic, pediatric surgery, abdominal transplant and breast oncology (p<0.01).
CE and QE/CE scores were higher for surgical critical care and hepatobiliary (p<.01).
In surgical oncology only higher CE pass rates were found (p<0.05). No significant
difference in pass rate was found for colorectal and MIS. In general surgery residency
programs with fellows, higher QE, CE and QE/CE scores were found in programs with
a high fellow to resident ratio (p<0.05). No significant difference was found between
general surgery residents who trained with no fellows compared to the ones who
trained in programs with a low fellow to resident ratio.
Conclusion: General surgery examinees performed better on ABS examinations when
trained in programs that had more fellows. This may represent a significant selection

P 54. CLINICAL CHARACTERISTICS OF SUPER-OBESE FEMALE
SURGICAL PATIENTS VARY BY RACE: ANALYSIS OF 1212 BOLD
DATABASE PATIENTS
MD Davis DO, GJ Slotman, MD
Vineland, NJ
Background: The obesity epidemic has transformed every surgical practice into a
bariatric office. Obesity affects more females than males, and every clinical insight
helps surgical care of these medically fragile women. Racial differences among superobese women have not been investigated. The objective of this study was to identify
clinical variations by race among super-obese female surgical patients.
Method: Pre-operative data from 1,212 women in the Surgical Review Corporation’s
BOLD database who chose bilio-pancreatic diversion/duodenal switch (BPD/DS) was
analyzed in five groups: African-American (n=106), Caucasian (n=1,000), Hispanic
(n=34), and Other (Pacific Islander, Native American, or >1 race listed in BOLD;
n=72). Age, weight and Body Mass Index (BMI) were compared by analysis of variance.
Dichotomous variable distribution was assessed by the Chi-squared equation.
Results: Black/Caucasian/Other/Hispanic weight (kg: 152.9+/-28., 138.5 +/-27.0,
138.8 +/-26.4, 136.2 +/-27.8), BMI (56.3 +/-10.1, 51.0 +/-9.2, 51.1 +/-9.0, 52.8 +/-11.4),
age (40.3 +/-10.3, 45.3 +/-11.3, 42 +/-12.4, 41.7 +/-10.8) varied significantly (p<0.0001),
as did unemployment (22.6%, 29.9%, 44.1%, 15.3%, p<0.05). Obesity co-morbidities
are detailed in Table 1. African-Americans had highest abdominal hernia, obstructive
sleep apnea, and stress urinary incontinence, and lowest cholelithiasis, GERD,
dyslipidemia, and pseudotumor cerebri. Caucasian mental health diagnoses, depression,
GERD, menstrual irregularities, polycystic ovarian disease and psychological
impairment were highest. Hispanics had the highest rates of abdominal panniculitis
dyslipidemia, pseudotumor cerebri, and pulmonary hypertension. Other group had the
highest stress urinary incontinence, and the lowest abdominal hernia and panniculitis,
mental health diagnosis, depression, menstrual irregularities, obstructive sleep apnea,
polycystic ovarian disease, psychological impairment, and pulmonary hypertension.
African American and Caucasians alcohol use was highest, and lowest in Other. Health
insurance, angina, asthma, back pain, congestive heart failure, DVT/PE, fibromyalgia,
functional status, diabetes, gout, HTN, ischemic heart disease, liver disease, lower
extremity edema, musculoskeletal, obesity hypoventilation, peripheral vascular disease,
substance abuse and tobacco use did not vary.
Conclusion: Super-obese women vary clinically by race. Pre-operative BPD/DS,
African-American females were heaviest, Caucasians oldest, and Hispanics most
unemployed. African-Americans were highest in 3 co-morbidities and lowest in 4,
versus Caucasians highest 7/lowest 0, Hispanics highest 5/lowest 0, and Other highest
1/lowest 10. This advance information can raise clinical suspicion for medical problems
in super-obese surgical patients, and may, thereby, facilitate improved peri-operative
surgical management.

P 55. TACKLE TRAUMA 5K RUN/WALK: A CONTEMPORARY AND
INNOVATIVE WAY TO INCREASE COMMUNITY AWARENESS AND RAISE
FUNDS TO REDUCE THE BURDEN OF TRAUMA
AJ Mangram MD, GR Shirah MD, J Sucher MD, CJ DHuyvetter MSN, MS Byrne
MSN, PA Prichard MD, KD Shatto BSN, MM Moyer, JR Leaf, JK Dzandu PhD
Phoenix, AZ
Background: The Arizona Trauma Association (ATA), formerly Arizona Trauma
& Acute Care Consortium, was established by level I trauma centers in Arizona to
provide leadership and education. The state of Arizona has seen a significant increase
in the number of American College of Surgeons verified and state designated trauma
centers in recent years. As a result, the ATA leadership has been seeking innovative
ways to collaborate, educate, generate funds for research, and enhance trauma
awareness. Although traumatic injuries remain the leading cause of death for children
and adults ages 1-49, we as trauma providers have not embraced the community as
a major stakeholder for awareness, education, research and revenue. Therefore, we
sought to establish a yearly community family-oriented 5Krun/walk for trauma as an
innovative method of generating funds for trauma research and injury prevention while
engendering community awareness and support.
Method: We identified Super Bowl Sunday for our yearly event as a symbol of
community and family gathering along with injury prevention opportunities. This was
a collaboration of multiple trauma centers within Arizona. Bi-weekly meetings started
in November with web and phone conferencing to accommodate all centers involved,
meetings increased to weekly in January.
Planning Committee agenda consisted of: advertisement and website development,
obtaining sponsorship, volunteer recruitment, medic-tent arrangement and day of event
planning. The course and timing were facilitated by professional race planners.
Results: From the inception to our first event race was 3 months. Our inaugural event
was a great success with 293 participants in 2015 and 307 in 2016. Our participants
included physicians, RN, NP, hospital personnel, Red Cross members, college students,
medical students, and community members at large. For the two years, participants
and sponsors generated $83,485, 11 sponsors in 2015 and 19 in 2016. Expenses for the
events totaled $19,311 making a net income for these events of $64,173 in two years.
Our second event was covered live on ABC.
Conclusion: In our effort to improve trauma care we must bring more attention
to the disease of trauma. This creative, contemporary event generated a spirited
community response and increased awareness of the burden of trauma all while gaining
a substantial profit, to aid in other trauma initiatives. First funding initiative will
revolve around texting and driving/walking as we have seen a significant increase in
pedestrian injuries related to texting. Our Tackle Trauma event can easily be replicated
nationwide, on Super Bowl Sunday morning.

P 56. TIMING IS EVERYTHING: OUTCOMES IN TRAUMATIC SUBDURAL
HEMATOMAS BASED ON TIME TO OR
RJ Caiafa MD, JW Davis MD, RC Dirks PhD
Fresno, CA
Background: Traumatic subdural hematomas (SDH) requiring operative intervention
occur relatively frequently. Per ACS-COT performance guidelines, craniotomy should
occur within 4 hours. These guidelines do not differentiate between patients with acute
(ASDH), mixed (MSDH) (both acute and chronic components), or chronic SDH
(CSDH). Patients with MSDH or CSDH often present with mild or no symptoms,
suggesting that they differ clinically from those with ASDH. The purpose of this
study was to determine if outcomes are dissimilar between patients with ASDH versus
MSDH or CSDH evaluated by time to OR. Our hypothesis was that time to OR had
less impact in patients with MSDH or CSDH.
Method: A retrospective review was performed of all patients with acute, mixed, and
chronic SDH due to trauma undergoing craniotomy at an ACS verified Level I trauma
center from 1/10 to 12/15. Data included age, GCS, ISS, time to OR, ICU length
of stay (LOS), hospital LOS, and outcomes. Groups were compared to patients with
ASDH who underwent craniotomy in ≤ 4 hours. Statistical analysis utilized Chi square
and Mann Whitney U tests, with significance attributed to a p-value <0.05.
Results: During the 5 year study period, 402 patients were admitted with SDH
requiring operative intervention: 260 ASDH, 50 MSDH, and 92 CSDH.
Conclusion: Patients with ASDH who go to the OR within 4 hours have a lower
GCS, higher ISS, and worse outcomes than those with MSDH or CSDH. Patients
with MSDH or CSDH with minimal neurologic findings may safely undergo surgery
outside the 4 hour window without worse outcomes. This suggests that patients’
neurologic status at time of presentation is more predictive of their outcomes than
time to OR. ACS-COT performance guidelines should be updated to reflect these
differences.

P 57. RELATIONSHIP OF OIL PRICES AND ACTIVITY TO TRAUMA
IN NORTHWESTERN NORTH DAKOTA
C Pratt MD, S Johnson MD, A Sahmoun PHD, R Szlabick MD
Grand Forks, ND
Background: The top oil producing counties in North Dakota have seen a rapid
change in the trauma activity with the rise and fall of oil prices. Oil production in the
state of North Dakota has risen from 30.8 to 432 million barrels from 2002 to 2015.
The active drilling rig count had risen from less than 20 to over 200 from 2002 to
2012; but then has fallen to 84 in 2015. This caused an initial influx of population into
the region that has plateaued. This region is largely a rural area served by critical access
hospitals. As the population and infrastructure have grown, and subsequently fallen;
this study was done to determine how the industry has and continues to affect trauma
systems in the region.
Method: Data from the North Dakota trauma database was collected for all trauma
patients in top oil producing counties that were admitted to the hospital from January
1, 2008 until December 31, 2015. Data collected included age, county of injury,
injury severity score (ISS), cause, work relation, time, transport method, and outcome
(mortality). Patients were assigned to early (2008-2010), late (2011-2013), and extended
(2014-2015). Severely injured was defined as ISS >15. Using SAS software Chi-square
test was used to analyze the differences between groups for categorical variables and
Wilcoxon signed-rank tests for continuous variables. Statistical significance was defined
as P-value < 0.05.
Results: 4821 patients met inclusion criteria. In the high oil production area there
was a 130% increase in total number of trauma admissions in the early vs. late time
period from 334 to 775 total admissions (p<0.05) with a fall to 746 in the extended
time period. Motor vehicle crashes were the most prevalent cause of trauma in the
high oil production area and more than doubled between the early (148) and late (438)
time periods (p<0.05), with downtrend of 356 being seen in the extended time period.
The occurrence of work related accidents and severely injured patients have similarly
fluctuated. Mortality of the severely injured patients has also fluctuated over the three
time periods starting at 7%, increasing to 13%, and finally decreasing to 8%.
Conclusion: Increased drilling for and production of oil during times of high oil prices
resulted in significant increases in trauma admissions and mortality in counties where
oil was produced. There is an increased need for trauma systems in areas of high oil
production. Continued study will be necessary to see if this trend remains despite the
decrease in oil prices and growth of the industry.

P 58. INCIDENCE OF ACUTE KIDNEY INJURY IN SEVERELY INJURED
PEDIATRIC TRAUMA PATIENTS IS NOT AFFECTED BY RECEIVING IV
CONTRAST
McGaha, Paul; Johnson, Jeremy; Garwe, Tabitha; Motghare, Prasenjeet; Daly,
William; Letton, Robert
Oklahoma City, OK
Background: Data for the incidence of acute kidney injury (AKI) related to
intravenous contrast administration in the pediatric trauma population is limited.
While obtaining a creatinine value prior to receiving IV contrast for elective CT scans
is a relatively accepted standard of care, we sought to determine whether there was
any significant difference in the incidence of AKI between severely injured pediatric
trauma patients who had a CT scan with IV contrast and those who did not receive IV
contrast.
Method: This was an Institutional Review Board approved single institution,
retrospective, study in which we reviewed the data from the trauma registry at our
Level 1 Adult and Pediatric Trauma Center between 2008 -2013. We limited the
patient population to severely injured (ISS > 15) pediatric trauma patients (<15 years
old) who were directly transported from the scene of injury and had a creatinine level
measured upon arrival. 1,214 patients were initially reviewed and 211 patients were
included in the study, as these 211 had a repeat creatinine. AKI was defined as a 50%
increase in creatinine that resulted in a post scan/arrival creatinine of >1.0 mg/dl within
24 hours. We then compared incidence of AKI in the groups who received a CT scan
with IV contrast (CON; n=166) versus the group that did not receive IV contrast (nonCON; n=47).
Results: The two groups were comparable in age, gender, GCS, ISS, mean creatinine
on arrival and mean creatinine post CT scan/arrival. There were significantly more
traumatic brain injuries in the non-CON group than the CON group (83% vs 59%; p
< 0.002). None of the patients in either group ever met criteria for AKI. Two patients
(4%) in the non-CON group and 9 patients (5%) in the CON group arrived with
a creatinine > 1.0mg/dl, none of which had any evidence of increasing creatinine
during their hospitalization. No patients required a nephrology consult during or after
hospitalization suggesting that clinically significant AKI did not occur during or after
their hospitalization.
Conclusion: Our study suggests that IV contrast is not associated with the
development of AKI in severely injured pediatric trauma patients. Although obtaining
a creatinine prior to exposure is ideal, obtaining an indicated CT scan with contrast in
severely injured children should not be delayed in order to obtain a creatinine value.

P 59. 10 YEAR RETROSPECTIVE REVIEW OF INJURY PATTERNS
BETWEEN 4-WHEELERS AND SIDE-BY-SIDE ALL TERRAIN VEHICLES
Shawn Olson MD
Grand Forks, ND
Background: All-terrain vehicles (ATVs) have increased in size and horsepower over
the last 45 years. Current models now offer 140 horsepower. Side-by-side configured
models or utility-terrain models (UTVs) were introduced in the late 80’s, but gained in
popularity over the last 10-15 years. The newest variety of side-by-side ATVs are sport
models that allow for high speed travel over uneven terrain. Safety features have also
been introduced with newer models having, seatbelts, doors or side curtains. There is
no available published literature to suggest whether newer ATV types are more or less
dangerous than previous models. North Dakota is a ideal research site as rural states
have a much higher per capita ATV related death rate than more densely populated
states.
Method: ATV-injured patients admitted to level II trauma centers in Eastern North
Dakota were reviewed between years 2004 through 2015. ATV Type, helmet/seatbelt
use, and length of stay were recorded. These were compiled with existing data for age,
sex, trauma activation level, safety device usage, GCS, length of stay, injury severity
score, mortality, and alcohol use. Data were analyzed with Chi-Squared and ANOVA
statistical models.
Results: The ten-year period produced 550 consecutive records for review. The number
of ATV trauma related patients each year increased from 32 to 53 admissions over the
10 year period. The number of side-by-side injured patients per year increased from 0
to 16. Overall, 75% of the patients were male, mean age was 31 years, 36% had alcohol
involved, 16% were helmeted and 48% were seat belted. The review demonstrated that
64% of the patients were riding traditional 4-wheelers, 13% side-by-sides, 3% threewheelers and 20% could not be determined what type of vehicle (ATV-NOS) was in
operation. Helmet use was 13% for 3-wheelers, 19% for 4-wheelers, 9% of side-by-sides
and 9% ATV-NOS riders. There were was no difference between ATV type and alcohol
use, trauma response level, length of stay, GCS, ISS and mortality rate.
Conclusion: This represents a large sample of ATV related injuries during a time frame
where ATVs became more powerful and different configurations became popular. ATV
type was able to be determined by retrospective chart review in the majority of cases.
ATV related injuries became more frequent over this time period with side-by-side
injuries becoming common. This study suggests that side-by-side configured ATVs do
not appear to result in more severe injuries.

P 60. FAILURE OF INTRACRANIAL PRESSURE RESPONSE TO
BARBITURATE COMA
RJ Vasak MD, A Sharp MD, DY Kim MD, DS Plurad MD
Torrance, CA
Background: Barbiturate coma is used as a medical therapy for refractory
intracranial hypertension (ICH). Its therapeutic benefit must be weighed against
its considerable side effect profile and variable metabolism. Despite achieving goal
electroencephalographic (EEG) burst suppression, many patients do not have a
therapeutic response in intracranial pressure (ICP).
Method: Utilizing our prospectively maintained trauma brain injury registry, we
identified 84 patients from the last 21 month period who had intracranial pressure
monitors placed. 15 patients were treated with barbiturate coma for refractory ICH. Of
these, data tracking clinical response to pentobarbital were retrospectively gathered.
Therapeutic response to pentobarbital was defined as an ICP<25 for the 24 hour period
after initiation of goal burst suppression. 73% of the patients were males with an overall
mean age of 34.1.
Results: 6 of the 15 patients had failure of ICP response to pentobarbital within the
first 24 hours. Of these patients, there was a 100% mortality and 50% went on to
organ donation. These six patients were on pentobarbital infusion for a mean of 2.33
days. After the start of infusion, all had episodes of hypotension, 2 developed lactic
acidosis, and 3 developed pneumonia.
Conclusion: Failure of ICP response within 24 hours to barbiturate coma in our series
was associated with 100% mortality. By incorporating these data into clinical decision
making, it may be possible to limit duration of barbiturate comas in patients for whom
there is no therapeutic benefit.

P 62. CORRELATING GEOGRAPHIC LOCATION WITH INCIDENCE OF
MOTOR VEHICLE INDUCED PEDESTRIAN INJURY
N Bhutiani MD, KR Miller MD, MV Benns, MD, NA Nash MD, GA Franklin MD,
JW Smith MD PhD, BG Harbrecht MD, CR Scoggins MD, MC Bozeman, MD
Louisville, KY
Background: Previous studies have demonstrated a positive correlation between
alcohol and illicit drug use and the likelihood of a pedestrian being struck by a motor
vehicle. However, to date, none have examined the relationship between infrastructural
and socioeconomic factors and the frequency of pedestrians sustaining traumatic
injuries from a motor vehicle. The objective of conducting this retrospective analysis
was to analyze the impact of location on the frequency of pedestrian injury by motor
vehicle.
Method: The University of Louisville Trauma Registry was queried for patients who
had been struck by a motor vehicle between January 2010 and December 2015. A total
of 615 such patients were identified and grouped by injury zip code. Demographic,
clinicopathologic, and outcome measures were recorded for each patient. Median
household income, population density, and median age for each zip code were also
recorded. Statistical analysis was performed after exclusion of all zip codes with fewer
than 5 incidents during the study period. Heat mapping was performed to evaluate
geographic distribution of incidents. The heat map was compared to a heat map of
motor vehicle accidents during the study period generated using publicly available
accident data. Statistical analyses were performed using the Pearson correlation. For all
analyses, p-values <0.05 were considered significant.
Results: Incidents of pedestrians being struck by motor vehicles clustered most densely
in the downtown Louisville area (Figure 1A). The distribution of these incidents did
not correspond directly to the distribution of motor vehicle accidents (Figure 1B).
Number of incidents was correlated with lower median household income (r=-0.47,
p=0.008). While there was a moderate correlation between number of incidents with
population density, this did not reach statistical significance (r=0.33, p=0.078). There
was no correlation between number of incidents and age (r=-0.10, p=0.59). Similarly,
there were no significant correlations between zip code demographic variables and
patient age, gender, ICU and total length of stay, abbreviated injury scale and injury
severity scale scores, and proportion of surviving patients.
Conclusion: Incidence of pedestrian injury by motor vehicles is influenced by
regional socioeconomic status. Efforts to decrease the frequency of these events should
include further investigation into the mechanisms underpinning this relationship and
identification of public safety programs and infrastructural improvements to educate
and protect pedestrians in such areas.

P 64. MANAGEMENT OF MULTIPLE RIB FRACTURES AND FLAIL CHEST
WITHOUT OPERATIVE RIB STABILIZATION AND IMPACT ON PATIENT
OUTCOMES
Hanna Park MD MPH, Esther Bae DO, David Wong MD, Samir John MD
Colton, CA
Background: Multiple rib fractures, including flail chest, can be a severe consequence
of thoracic trauma, resulting in high morbidity and mortality. Surgical management
of rib fractures has been gaining popularity but there are no definitive, randomized
trials that demonstrate it’s superiority to multidiscipkinary, nonoperative management.
Moreover, rib stabilization can he rare but morbid complications. Our aim was to
validate multidisciplinary strategies in management of multiplease rib fractures and
flail chest without rib stabilization.
Method: We performed a retrospective analysis of adult trauma patients (n=96) with
a median Injury Severity Score of 12.5 (range 4-43) who presented to Arrowhead
Regional Medical Center with multiple rib fractures and flail chest between December
2015 to March 2016. Patients with three or more rib fractures (four or more if under
age 65) were included; fourteen patients had flail chest by traditional definition
(21.2%). We excluded any patient who died within 24 hours of arrival. Sixty-six
patients met inclusion criteria. Primary outcomes included days on ventilator, days in
intensive care unit as well as total hospital days, incidence of pneumonia, and mortality.
Results: Patients averaged 6.2 ventilator days (1-16), 5.5 intensive care unit days (118), 8 total hospital days (1-46). Nine percent of patients developed pneumonia during
hospitalization. In-hospital mortality averaged 4.5%. When compared to published
data for surgically stabilized patients, management of multi-rib fractures and flail chest
without operative rib stabilization in thoracic trauma patients results in comparable
outcomes with respect to length of ventilator support, incidence of pneumonia, total
ICU and hospital days, as well as mortality.
Conclusion: Multidisciplinary management for multiple rib fractures and flail chest
without rib stabilization has comparable outcomes to surgical fixation. With rare
exceptions, it should continue to be considered standard of care for this population of
severely injured patients.

P 65. THE FAST EXAM CAN RELIABLY IDENTIFY PATIENTS FOR ZONE
III RESUSCITATIVE ENDOVASCULAR BALLOON OCCLUSION OF
THE AORTA (REBOA) DEPLOYMENT IN LIFE THREATENING PELVIC
FRACTURES
NT Townsend MD, CC Burlew MD, EE Moore MD, AE Geddes MS, AE Wagenaar
MD, C Fox MD, FM Pieracci MD
Denver, CO
Background: While there is enthusiasm for REBOA use in zone III for unstable
pelvic fractures, there is controversy over placement in zones I and II. Additionally,
delineating associated intraabdominal hemorrhage using the Focused Abdominal
Sonography for Trauma (FAST) exam in these multiply injured patients has been
reported to be unreliable. We hypothesized that FAST is a reliable method for detecting
clinically significant intraabdominal hemorrhage in the face of complex pelvic fractures
and can be used to direct the use of REBOA in life threatening pelvic injuries.
Method: Our pelvic fracture database of all hemodynamically unstable patients
requiring intervention from 1/1/05 to 7/1/15 was reviewed. FAST exam performed in
the ED was compared to operative and CT scan findings. Confirmatory evaluation
for FAST(-) patients was considered positive if therapeutic intervention was required.
Patients with imaging at an outside hospital or no recorded FAST in the ED were
excluded.
Results: During the study period, 81 patients in refractory shock with FAST imaging
in our ED underwent pelvic packing. Mean age was 45 ± 2 (range 6 to 88) years and
ISS was 50 ± 1.5. FAST exam results and subsequent confirmatory evaluation are
reported. The sensitivity and specificity for FAST in this hemodynamically unstable
pelvic fracture population was 96% and 96% respectively; PPV was 93% and NPV was
98%. The false negative and positive rates for FAST were 2% and 7%.
Conclusion: FAST reliably identifies clinically significant hemoperitoneum in life
threatening, pelvic fracture related hemorrhage. The incidence of false negative FAST
in this unstable pelvic fracture population was 2%. FAST results can reliably be used
when determining the role of REBOA in these multisystem trauma patients. Placement
of REBOA in hemodynamically unstable pelvic fracture patients who are FAST(-)
should be considered while caution should be used in FAST(+) patients.

P 11. HEMOSTATIC MASSIVE TRANSFUSION PROTOCOLS AND TRAUMA
LAPAROTOMIES
SF Mclean MD, AH Tyroch MD
El Paso, TX
Background: Massive transfusion protocols (MTP) have been created to improve
resuscitation of bleeding trauma patients. MTP associated with laparotomy have
been associated with abbreviated laparotomy ( AL) designed to optimize physiologic
resuscitation. Recently, attention has focused on MTP design to aid coagulation.
Although it has been shown that AL with MTP enhances survival, studies on specific
MTP have not been done. The purpose of this study was to examine the relationship
between a newer, hemostatic MTP, incidence of AL, number of OR trips for closure,
and survival; compared with old-style non-hemostatic MTP. Hypothesis was that
hemostatic MTP (H-MTC) would improve survival compared with other types of
massive transfusion or non-protocolled transfusion.
Method: In a level-one trauma center, the massive transfusion protocol was revamped
to maintain a 1:1:1:1 ratio of PRBC: FFP: Platelets: cryoprecipitate. A retrospective
chart review was used to examine activation of new MTP, AL, eventual closure type,
survival. Chi square was used to assess categorical variables and T-test was used to
evaluate continuous variables.
Results: 258 consecutive laparotomies, 2012-2015, 252 with operative notes occurred.
Mean ISS was 20.3, Mean LOS was 16.3 days, Mean ICU LOS was 14.4 days. A
transfusion occurred in 150 (58%). H_MTC occurred in 65 (25%), old MTC in
2, 83 (32%) transfused, no MTP. Of the H_ MTP, mean (range )totals ( in units):
Mean PRBC : 26.5(3-184), Mean FFP: 21.8 0-145), Mean platelets 28 (0-180) ,
Cryoprecipitate 18.6 (0-200).
Analyzing laparotomies, 118 had AL (45.7%). 55(47%) of AL patients had H-MTC;
53.4% did not; of those closed 1st case, only 9(6.7%) had HMTC, 2 Old MTC(1.5%).
This was significant, p=.000. In AL patients, 107 (91%) had 1st closure with negative
pressure wound therapy. 61 (52%) were able to be closed primarily at second closure, 27
(23%) had repeated NPWT, 4 Wittman patch. Looking only at AL patients, 46 (81%)
of those with no MTC vs 37% of those with hemostatic MTC and AL had primary
closure at 1st takeback. (p=.000). Primary fascial closure was achieved in 55% of
H-MTC patients vs. 88% in no-MTC patients. (p=.000).
For patients with H-MTC 86% had AL, compared to 34% with no MTC. (p=.000).
Comparing postoperative issues which may indicate visceral edema, there was no
significant difference in percent of dehiscence or compartment syndrome, but there was
an increase incidence of reopening in patients who had H-MTC (5.9% of no MTC vs.
12.7% of H-MTC patients reopened (p=.020). 8 Wittman patches were evenly divided
among no vs HMTC groups.

Overall survival in this group was 86.8%, compared to previous laparotomies (n-742)
from 2013-2011, where survival was 85%, with mean ISS of 21.9. 66% of H-MTC
patients survived vs 95% of those with no MTC, (p=.000); Patients with HMTC had
ISS mean 31 vs. 16.6 in patients with no MTC (p=.000).
Conclusion: Hemostatic MTC was achieved in 65 patients since 2012. Those patients
had higher ISS and decreased survival compared with patients who did not require
MTC. MTC was associated with increased rate of AL and re-opening after closure.
Although MTC was lifesaving, it is associated with the problems of repeated takebacks
and reopening and lower rates of primary fascial closure for final closure.
