Prevesical peritoneum interposition to prevent risk of rectovaginal fistula after en bloc colorectal resection with hysterectomy for endometriosis: Results of a pilot study

Abstract : Objective: To evaluate the risk of rectovaginal fistula after en bloc hysterectomy and colorectal resection (H-CR) for endometriosis using prevesical peritoneum interposition. Study design: A retrospective study conducted at Tenon University Hospital, expert center in endometriosis, from June 2016 to June 2018. Patients undergoing H-CR with prevesical peritoneum interposition without protective defunctioning stoma were included. Results: Of the 160 patients who underwent surgery with colorectal resection for endometriosis during the study period, 27 had H-CR (15 with segmental and 12 with discoïd colorectal resection) and were included. The median age (range) was 45 years (41-47.5). Eight patients (13 %) were nulliparous. All procedures were performed by laparoscopy. Parametrial resection was performed in 14 cases (52 %). Associated bowel procedures were ileocecal resection (n = 5) and appendectomy (n = 2). Median follow-up (range) was 14.6 months (10.5-20.2). Nine (33.3 %) patients experienced intra- or postoperative complications including one grade I, four grade II, two grade IIIA and two grade IIIB complications (Clavien-Dindo classification). Seven patients (26 %) experienced postoperative voiding dysfunction. One suspicion of rectovaginal fistula associated with pelvic abscess was diagnosed 4 weeks after surgery but not confirmed during a second operation. Conclusion: Despite the small sample size, the present pilot study supports the practice of prevesical peritoneum interposition to limit the risk of rectovaginal fistula in patients who undergo H-CR for deep endometriosis.
