Abstract

Objective:

To evaluate the effect of surgically induced weight loss on pelvic floor disorders (PFD) in morbidly obese women.

Summary Background Data:

Although bariatric surgery may lead to the improvement of some obesity-related comorbidities, the resolution of global PFD has not been well described.

Methods:

Women with a body mass index (BMI) of 35 kg/m2 or more who were considering bariatric surgery were asked to complete 2 validated condition-specific questionnaires assessing the distress/quality of life impact of PFD, total and by domain (pelvic organ prolapse, colorectal-anal, and urogenital). Women who achieved a ≥50% excess body weight loss after surgery were asked to complete the same questionnaires for comparison.

Results:

Of the 178 women who underwent surgery, 46 completed the postoperative questionnaires. Mean age of this group was 45 years (range, 20–67), and mean preoperative BMI was 45 kg/m2 (range, 35–75). The prevalence of PFD symptoms improved from 87% before surgery to 65% after surgery (P = 0.02, 95% CI: 0.05%–53%). There was a significant reduction in total mean distress scores after surgery (P = 0.015, 95% CI: 3.3–32.9), which was attributed mainly to the significant decrease in urinary symptoms (P = 0.0002, 95% CI: 8.2–22.7). Reductions in the scores were noted for the other PFD domains as well. Quality of life total scores improved (P = 0.002, 95% CI: 4.8–27.1), as did scores in the urinary domain (P = 0.0005, 95% CI: 3.8–13.5) and the pelvic organ prolapse domain (P = 0.015, 95% CI: 0.6–9.5). Age, parity, history of complicated delivery, percent excess body weight loss, BMI, type of weight loss procedure and presence of diabetes mellitus and hypertension had no predictive value for postoperative outcomes.

Conclusion:

Surgically induced weight loss has a beneficial effect on symptoms of PFD in morbidly obese women.
