Evolution of Bowel Complaints after Laparoscopic Endometriosis Surgery: A 1497 Women Comparative Study

Study Objective: To assess to what degree can digestive symptoms improve after endometriosis surgery for different localizations. Design: A comparative retrospective study employing data prospectively recorded in the North-West Inter-Regional Female Cohort for Patients with Endometriosis (CIRENDO) from June 2009 to November 2018. Setting: Two referral centers. Patients: A total of 1497 women undergoing surgery because of pelvic endometriosis were divided into 3 groups: superficial endometriosis (Group 1, n = 396), deep endometriosis sparing the bowel (Group 2, n = 337), and deep endometriosis involving the bowel (Group 3, n = 764). Interventions: Surgery for endometriosis. Measurements and Main Results: Preoperative and postoperative gastrointestinal symptoms were evaluated with standardized questionnaires, including the Gastrointestinal Quality of Life Index (GIQLI) and Knowles-Eccersley-Scott-Symptom questionnaire (KESS). The degree of postoperative improvement in digestive symptoms was compared between the groups. The women in Group 3 were significantly symptomatic in terms of cycle-related gastrointestinal symptoms and scores of standardized questionnaires GIQLI and KESS. According to the 1-year postoperative evaluation, women in Group 3 experienced the most significant improvement in their gastrointestinal symptoms. Conclusion: Women with severe bowel symptoms and deep endometriosis infiltrating the bowel should be informed about the high probability of symptom improvement after the removal of bowel nodules. Conversely, in women without deep endometriosis, postoperatively, there is less improvement in baseline digestive complaints.
