Objective: To further the understanding of long-term outcomes of endometriosis patients requiring colonic segmental resection (CSR) or low anterior resection (LAR). To improve counseling of patients with bowel endometriosis. Methods: Retrospective chart review at a single academic institution between 2000-2018 with 3- year follow-up of patients with CSR/LAR for endometriosis. 21 patients aged 18-45 at single academic institution between 1/1/2000 and 12/31/2018 with ICD9&10 codes of endometriosis AND CSR/LAR were included; 9 met criteria for endometriosis as indication for CSR/LAR were reviewed. Results: Pre- and post-operative symptoms were categorized into GI (hematochezia, dyschezia, tenesmus, incontinence, incomplete evacuation of bowel, and pre-operative colonoscopy), GYN (dysmenorrhea, dyspareunia, pelvic pain, and infertility), and GU (dysuria, frequency, urgency, incontinence, and incomplete emptying).
