Omentoplasty to assist perineal defect closure following laparoscopic abdominoperineal resection.

Abstract

This technical note describes laparoscopic production of a well vascularized, omental flap of adequate size to fill the pelvic floor defect in the course of laparoscopic abdominoperineal resection (LAPR). The omentum is laparoscopically mobilized and transposed to the pelvis following full LAPR in three discrete stages. Laparoscopic omental mobilization, transfer and buttressing of a primary perineal repair reduces pelvic dead space and facilitates closure following LAPR with minimal additional operative time or complications and a potential reduction in perineal wound associated morbidity. Laparoscopic omental mobilization is technically feasible and provides a safe method to aid perineal wound closure.
