STUDY OBJECTIVE: To assess long-term bowel symptoms in women who underwent segmental bowel resection for deep-infiltrating endometriosis (DIE) compared with women who underwent resection of severe endometriosis without bowel resection. DESIGN: Cohort study with matched controls (Canadian Task Force classification II-2). SETTING: Cleveland Clinic. PATIENTS: 71 patients (36 cases and 35 controls). INTERVENTIONS: Patients who were at least 4 years out from undergoing segmental bowel resection due to DIE were matched with patients who had undergone resection of stage III/IV endometriosis without bowel resection. The patients completed validated questionnaires, and data were analyzed using the Wilcoxon rank-sum, χ(2), and Fisher exact tests. MEASUREMENTS AND MAIN RESULTS: The Bristol Stool Form Scale, Patient Assessment of Constipation Symptoms Questionnaire (PAC-SYM), and St Mark's Vaizey Fecal Incontinence Grading System were used to elicit information. The median duration of follow-up was 10.1 years (range, 4-18 years). The mean patient age and body mass index were comparable in the cases and the controls. A larger proportion of cases than controls reported new bowel symptoms (58% [21 of 36] vs 14% [5 of 35]; p = .001), as well as abdominal pain, incomplete bowel movements, and false alarms on the PAC-SYM questionnaire; however, total PAC-SYM and Vaizey Fecal Incontinence Grading System scores were similar in the 2 groups (median, 8 [interquartile range, 8-10] vs 8 [8-10]; p = .86). Similarly, the proportion of patients with normal stool consistency (Bristol Stool Form Scale score 2-6) was similar in the 2 groups (80.6% [29 of 36] vs 94.3% [33 of 35]; p = .59). CONCLUSION: Segmental bowel resection for DIE may be associated with a higher incidence of new bowel symptoms (possibly due to abdominal pain, incomplete bowel movements, and/or false alarms), but not with worse constipation or fecal incontinence, compared with surgery without bowel resection.

Dr. Jelovsek is the F. Bayard Carter Distinguished Professor of OBGYN at Duke University and serves as Director of Data Science for Women’s Health. He is Board Certified in OBGYN by the American Board of OBGYN and in Female Pelvic Medicine & Reconstructive Surgery by the American Board of OBGYN and American Board of Urology. He has an active surgical practice in urogynecology based out of Duke Raleigh. He has expertise as a clinician-scientist in developing and evaluating clinical prediction models using traditional biostatistics and machine learning approaches. These “individualized” patient-centered prediction tools aim to improve decision-making regarding the prevention of lower urinary tract symptoms (LUTS) and other pelvic floor disorders after childbirth (PMID:29056536), de novo stress urinary incontinence and other patient-perceived outcomes after pelvic organ prolapse surgery, risk of transfusion during gynecologic surgery, and urinary outcomes after mid-urethral sling surgery (PMID: 26942362). He also has significant expertise in leading trans-disciplinary teams through NIH-funded multi-center research networks and international settings. As alternate-PI for the Cleveland Clinic site in the NICHD Pelvic Floor Disorders Network, he was principal investigator on the CAPABLe trial (PMID: 31320277), one of the largest multi-center trials for fecal incontinence studying anal exercises with biofeedback and loperamide for the treatment of fecal incontinence. He was the principal investigator of the E-OPTIMAL study (PMID: 29677302), describing the long-term follow up sacrospinous ligament fixation compared to uterosacral ligament suspension for apical vaginal prolapse. He was also primary author on research establishing the minimum important clinical difference for commonly used measures of fecal incontinence. Currently, he serves as co-PI in the NIDDK Symptoms of Lower Urinary Tract Dysfunction Research Network (LURN) (U01DK097780-05) where he has been involved in studies in the development of Symptoms of Lower Urinary Tract Dysfunction Research Network Symptom Index-29 (LURN SI-29) and LURN SI-10 questionnaires for men and women with LUTS. He is also the site-PI for the PREMIER trial (1R01HD105892): Patient-Centered Outcomes of Sacrocolpopexy versus Uterosacral Ligament Suspension for the Treatment of Uterovaginal Prolapse.
