Risk of Postoperative Stenosis after Segmental Resection versus Disk Excision for Deep Endometriosis Infiltrating the Rectosigmoid: A Retrospective Study

To assess the prevalence, risk factors, and management of bowel stenosis after surgery for deep infiltrating endometriosis of the rectosigmoid using either disk excision (DE) or segmental resection (SR). Retrospective study using data from consecutive cases recorded in the North-West Inter Regional Female Cohort for Patients with Endometriosis database. University tertiary referral center. Four hundred thirty-one consecutive patients managed for rectosigmoid endometriosis were enrolled in our study. Laparoscopic SR or DE. One hundred sixty-five patients underwent DE, and 266 patients underwent SR. Large nodules ≥3 cm in diameter were more frequent in the SR group (73.3% vs 66.1%), whereas nodules infiltrating the low rectum were 3 times more frequent in the DE group (35.9% vs 11.3%). The frequency of vaginal excision (67.9% vs 62%) and stoma (46.7% vs 44.4%) were comparable between the DE and SR groups. Twenty-three patients presented with postoperative colorectal stenosis after SR (8.6%) versus none after DE (p
