Omentoplasty to assist perineal defect closure following laparoscopic abdominoperineal resection

Abstract

AIM: 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). METHOD: The omentum is laparoscopically mobilized and transposed to the pelvis following full LAPR in three discrete stages. RESULTS: 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. CONCLUSION: Laparoscopic omental mobilization is technically feasible and provides a safe method to aid perineal wound closure.
