"Minimal to slight foreign body responses
have been routinely seen in multiple
preclinical tissue reaction studies with
VICRYL suture (usually muscle
implantation), a typical tissue response to
a foreign body that on occasion included
foreign body giant cells. The tissue
responses were not excessive and were
considered a normal response to a foreign
body."
In regard to internal sutures
Pg-910 showed a 66% increase

Conclusion
•We need to be clearer when
describing wound problems
•Not all wounds lead to complications
•Haematomata may not be obvious for
21 days
•Steroids may compound haematoma
effects
•PG-910 reaction is accelerated with
haematoma
•Infection remains unproven
