Vascular‐ and nerve‐sparing bowel resection for deep endometriosis: A retrospective single‐center study

Abstract

AbstractObjectiveSurgical management of bowel endometriosis is still controversial. Recently, many authors have pointed out the potential benefits of preserving the superior rectal artery, thus ensuring better perfusion of the anastomosis. The aim of this study was to evaluate the complication rate and functional outcomes of a bowel resection technique for deep endometriosis (DE) involving a nerve‐ and vascular‐sparing approach.MethodsA single‐center retrospective study was conducted by enrolling patients who underwent segmental resection of the rectus sigmoid for DE in our department between September 2019 and April 2022. Intraoperative and postoperative complications were recorded for each woman, and functional outcomes relating to the pelvic organs were assessed using validated questionnaires (Knowles‐Eccersley‐Scott‐Symptom [KESS] questionnaire and Gastro‐Intestinal Quality of Life Index [GIQLI] for bowel function, Bristol Female Lower Urinary Tract Symptoms [BFLUTS] for urinary function, and Female Sexual Function Index [FSFI] for sexual function). These were evaluated preoperatively and postoperatively after 6 months from surgery.ResultsSixty‐one patients were enrolled. No patients had Clavien‐Dindo grade 3 or 4 complications, there were no rectovaginal fistulas or ureteral lesions, and in no cases was it necessary to reoperate. Temporary bladder voiding deficits were reported in 8.2% of patients, which were treated with self‐catheterizations, always resolving within 45 days of surgery. Gastrointestinal function evaluated by KESS and GIQLI improved significantly after surgery, whereas sexual function appeared to worsen, although without reaching the level of statistically significant validity.ConclusionOur vascular‐ and nerve‐sparing segmental bowel resection technique for DE had a low intraoperative and postoperative complication rate and produced an improvement in gastrointestinal function after surgery.
