Laparoscopic Roux-En-Y Gastric Bypass Versus Sleeve Gastrectomy on Pelvic Floor Disorders in Morbidly Obese Women: a Prospective Monocentric Pilot Study

Obesity is a well-known risk factor for female pelvic floor disorders (PFD). This study assessed the effects of bariatric surgery (BS) on pelvic organ prolapse symptoms (POPs) and urinary (UI) and anal incontinence (AI) in morbidly obese women undergoing either sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB).
Morbidly obese women undergoing BS from June 2016 to May 2017 were prospectively included. POPs, UI, and AI were compared at baseline and at 1 year after surgery using validated questionnaires.
Seventy-two consecutive women were enrolled, 54 (75%) (30 (56%) RYBP and 24 (44%) SG) completed the study at 1 year and were considered for the final analysis. The mean age and mean preoperative BMI were 43 ± 11.8 years (range, 20–65) and 41 ± 5.4 kg/m2 (range, 35–56), respectively. At baseline, 30 (56%), 32 (59%), and 27 (50%) patients, respectively, had AI (flatus only 72%), UI, and POPs. The mean TBWL% at 1 year was 33%. In the whole study population, weight loss was associated with a significant improvement in UI (p < 0.001) but there was no significant difference in terms of AI and POPs. In the subgroups analysis, AI increased significantly 1 year after the RYGB (p = 0.02) due to an increase in flatus incontinence (p = 0.04). No significant difference in AI was found 1 year after the SG.
BS is associated with a significant improvement in UI but not in POPs. RYBP seems to increase AI, mainly flatus incontinence, compared to SG.
