Objective: To compare the prevalence of pelvic organ prolapse in subjects with defecatory disorders with that in control subjects. Methods: In 55 subjects with fecal incontinence, 42 subjects with obstructed defecation, and 45 healthy subjects without defecatory symptoms, a urogynecologist assessed pelvic organ prolapse by the pelvic organ prolapse quantification system, and a gastroenterologist evaluated perineal descent during simulated evacuation. A multiple logistic regression model evaluated whether obstetric-gynecological variables, including pelvic organ prolapse, could discriminate among controls, subjects with fecal incontinence, and subjects with obstructed defecation. Results: Fifty-five percent of controls, 42% of those with obstructed defecation, and 29% of those with fecal incontinence had stage Ⅱ or greater prolapse by clinical examination. Eleven percent of controls, 7% of those with obstructed defecation, and 47% of subjects with fecal incontinence had a forceps delivery. Eighteen percent of controls, 31% of those with obstructed defecation, and 64% of those with fecal incontinence had a hysterectomy. Even after controlling for a higher prevalence of obstetric risk factors and hysterectomy, fecal incontinence was associated with a lower risk of stage Ⅱ or greater pelvic organ prolapse (odds ratio for fecal incontinence in ≥ stage Ⅱ pelvic organ prolapse relative to stage 0 pelvic organ prolapse = 0.1, 95% confidence interval 0.01-0.53). In contrast, pelvic organ prolapse severity was not associated with control versus obstructed defecation status. Seven percent of controls, 18% of subjects with obstructed defecation, and 7% of those with fecal incontinence had increased perineal descent during simulated evacuation. Excessive perineal descent was associated (P <.01) with pelvic organ prolapse. Conclusion: Despite a higher prevalence of risk factors for pelvic floor injury, pelvic organ prolapse severity was lower in those with fecal incontinence than in subjects without bowel symptoms. However, a subset of subjects with defecatory disorders, predominantly obstructed defecation, have excessive perineal descent, which is associated with pelvic organ prolapse.
