Background: Treatment of anorectal abscesses continues to revolve around early surgical drainage and control of perianal sepsis. Yet even with prompt drainage, abscess recurrence and postoperative fistula formation rates are as high as 40% within 12 months. These complications are thought to be associated with inadequate drainage, elevated bacterial load, or a noncryptoglandular etiology of disease. Read More

Aim: Perineal wound complications and pelvic abscesses remain a major source of morbidity after total pelvic exenteration. The void created in the pelvis after these multi-visceral resections leads to fluid accumulation and translocation of bowel within the pelvic cavity, which may increase the risk of pelvic abscess, perineal fluid discharge with perineal wound dehiscence and prolonged ileus. This study describes a novel technique using degradable synthetic mesh with overlying omentum to preclude small bowel and fill the empty space after total pelvic exenteration, and aimed to investigate the rate of pelvic abscess and perineal wound-related complications in this group.
