Introduction And Hypothesis: Endometriosis is a gynecological condition characterized by endometrial tissue outside of the uterus. It affects up to 15% of women of reproductive age. In the case of bowel infiltration, about 90% of lesions are localized on the sigmoid colon or the rectum and may interfere with bowel function. Three surgical approaches are possible: (1) shaving technique, (2) discoid resection of the nodule, and (3) segmental resection with end-to-end anastomosis. A rectovaginal fistula is feared as a postoperative complication mainly in simultaneous resection of the vaginal and the rectosigmoid nodules. Its prevention is a two-step surgery (the first operation on the vagina and the second on the colon) or a preventive colostomy, both of which are often thought to be too invasive for a benign condition. Herein, we suggest a one-step surgery to prevent its development.

Methods: In three women, a concomitant laparoscopic resection of the vaginal and rectosigmoid endometrial nodule was completed with interposition of a mesorectal flap.

Results: All surgeries were uncomplicated with no rectovaginal fistula in the postoperative period.

Conclusion: In the hands of skilled surgeons, this one-step technique can be used to prevent rectovaginal fistula development.
