Two specimens are usually taken and must be kept separate and labeled as such. • Surgeon slowly dialates the cervix using Hegar or Hanks uterine dilators. • Surgeon places a Telfa strip over the speculum. • Surgeon gently curettes uterus, allowing the endometrial specimen to collect on the Telfa. • Surgeon passes endometrial specimen to technologist, and removes the speculum. • Surgeon or scrun person dresses perineum with a perineal pad. Procedure for Repair of a Cystocele and Rectocele • Patient is placed in lithotomy position, prepped, and circulator performs a • straight catherization. • Surgeon inserts a weighted speculum into the vaginal outlet, grasps the cervix • with a tenaculum, and brings it forward. • Surgeon makes an incision in the anterior vaginal wall. • Incision edges are grasped with several clamps and retracted. • Surgeon deepens the incision with sharp and blunt dissection, and advances the • incision through the vaginal wall and into the fascia that lies behind it using additional clamps as needed. • When bladder neck is reached, surgeon places several absorbable sutures, • size 0, through the fascia, thus tightening the tissue to prevent the bulging. • Surgeon excises the vaginal mucosa, and approximates the vaginal walls with • absorbable sutures to complete the anterior repair. • To begin the posterior repair, surgeon places 2 Allis clamps on each side of the vaginal outlet on the posterior side. • Assistant offers traction with the clamps while surgeon makes a transverse incision in the mucosa. • Surgeon deepens the incision with curved Mayo or Metzenbaum scissors to the level of the rectum. • To correct the bulging of the rectum, surgeon brings the levator muscles together with interrupted absorbable sutures, size 2-0. • Surgeon excises the excess vaginal mucosa, and reconstructs the vaginal wall with interrupted absorbable sutures, size 2-0 swaged to a small needle. • Surgeon usually inserts a Foley or suprapublic catheter, and dresses the vagina with medicated packing. Vaginal Hysterectomy • Patient is placed in the lithotomy position, prepped, and bladder is drained. • Surgeon grasps the cervix with a uterine tenaculum, and makes a circular incision • around the cervix using the knife or curved Mayo scissors. • Surgeon double-clamps, divides, and ligates the first set of ligaments with absorbable • suture ligatures of size 1 or 0 mounted or swaged to a heavy tapered needle. • Surgeon picks up the posterior peritoneum with toothed tissue forceps and incises it • with the knife or scissors. • Surgeon detaches the peritoneal attachment to the bladder with Mayo scissors. • Surgeon continues mobilization of the uterus using long tissue forceps and long • dissecting scissors. • When uterus is mobilized, surgeon delivers it to the technologist as a specimen. • Surgeon reperitonealizes the bladder, closes the peritoneum, inserts a Foley catheter, • and may dress the wound with a perineal pad. Procedure for Abdominal Hysterectomy • Patient is placed in supine position, prepped, abdominally and vaginally and a Foley • catheter is inserted. • Surgeon incises abdomen using a lower midline incision or Pfannanstiel incision, and • deepens the incision through the subcutaneous tissue with the deep knife or electrosurgical pencil. • Surgeon nicks fascia with the knife, incises with curved Mayo scissors, grasps fascial • margin with two or more Kocher clamps, and separates fascia from underlying muscle using blunt dissection. • Surgeon divides the muscle layer manually. • Surgeon nicks peritoneum with the knife, lengthens with Metzenbaum scissors, and places in wound a self-retaining retractor such as O’Connor-O’Sullivan or Balfour. • Surgeon packs bowel away from the uterus with moist lap sponges. • Surgeon isolates the uterus by severing it from the uterine ligaments, ovaries, and fallopian tubes by double-clamping, dividing, and ligating with absorbable sutures. • Surgeon separates the uterus and the bladder using Mayo scissors and tissue forceps by dissecting the peritoneal covering away from the bladder. • Surgeon mobilizes uterus, places long Allis or Kocher clamps around the margin of the vaginal cuff, and then divides it from the vagina using long scissors or the long knife to completely free the uterus. • Surgeon passes uterus to technologist as a specimen and places all instruments that have come in contact with the cervix or vagina in the designated basin. • Surgeon closes vaginal vault usually with the same type of suture used on the uterine ligaments while a sponge count is taken. • Surgeon reperitonealizes the bladder flap with 20 or 3-0 absorbable swaged suture. • Surgeon closes the layers of the abdomen using sutures of choice. Procedure for Laparoscopy • Patient is placed in a modified lithotomy position with lowered stirrups, is vaginally • and abdominally prepped, and the bladder is drained. • Technologist gloves surgeon. • Surgeon inserts uterine manipulator into the cervix. • Circulator removes surgeon’s gloves and technologist gowns and gloves the surgeon. • Surgeon makes a small nick in the abdominal wall close to the umbilicus. • Surgeon inserts an insufflation needle through the incision and attaches a 10-cc syringe filled with saline solution so the surgeon can aspirate to make sure that a blood vessel has not been punctured. • Surgeon attaches a length of flexible tubing to the needle while one end of the tubing is passed to the circulator, who connects it to the insufflator. • Circulator activates the insufflator and the abdomen is slowly filled with carbon dioxide which creates a pneumoperitoneum. • When sufficient gas has entered the abdomen, surgeon withdraws the needle • Technologist dips scope in hot water or antifogging solution wipes the lens with soap so the scope’s lenses do not fog. • Surgeon inserts the laparoscope into the sleeve and connects the light source cable. • Surgeon examines the abdominal contents for disease or injury, and then performs whatever additional procedure is decided upon, if needed. • Surgeon allows gas to escape through the sleeve, removes the sleeve, closes the incision(s) with subcuticular absorbable suture, and dresses with adhesive-bandages (Band-Aids).
