Functional Outcomes After Rectal Resection for Deep Infiltrating Pelvic Endometriosis: Long-term Results

BACKGROUND: Curative management of deep infiltrating endometriosis requires complete removal of all endometriotic implants. Surgical approach to rectal involvement has become a topic of debate given potential postoperative bowel dysfunction and complications. OBJECTIVE: This study aims to assess long-term postoperative evacuation and incontinence outcomes after laparoscopic segmental rectal resection for deep infiltrating endometriosis involving the rectal wall. DESIGN: This is a retrospective study of prospectively collected data. SETTINGS: This single-center study was conducted at the University Hospital of Bern, Switzerland. PATIENTS: Patients with deep infiltrating endometriosis involving the rectum undergoing rectal resection from June 2002 to May 2011 with at least 24 months follow-up were included. MAIN OUTCOME MEASURES: Aside from endometriosis-related symptoms, detailed symptoms on evacuation (points: 0 (best) to 21 (worst)) and incontinence (0–24) were evaluated by using a standardized questionnaire before and at least 24 months after surgery. RESULTS: Of 66 women who underwent rectal resection, 51 were available for analyses with a median follow-up period of 86 months (range: 26–168). Forty-eight patients (94%) underwent laparoscopic resection (4% converted, 2% primary open), with end-to-end anastomosis in 41 patients (82%). Two patients (4%) had an anastomotic insufficiency; 1 case was complicated by rectovaginal fistula. Dysmenorrhea, nonmenstrual pain, and dyspareunia substantially improved (p
