排便异常患者的盆腔脏器脱垂

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.

阴道破裂与脏器摘除术患者的特征

OBJECTIVE: To characterize vaginal rapture and evisceration. METHODS: We reviewed medical records (1970-2001) for use of the diagnostic terms “vaginal rupture,”“vaginal evisceration,”and “ruptured enterocele.”RESULTS: Twelve clinical cases were identified. Patients usually presented with pain, vaginal bleeding, and abdominal pressure. In 9 of 12 women, rupture was primarily associated with postmenopausal prolapse and a history of pelvic surgery. Women with a history of abdominal hysterectomy tended to rupture through the vaginal cuff, and those with a history of vaginal hysterectomy tended to rupture through a posterior enterocele. Premenopausal rupture in 1 woman occurred postcoitally and involved the posterior fornix. Prolapse recurrence after repair was limited to 1 woman. CONCLUSIONS: Vaginal rapture and evisceration should be considered in women presenting with acute vaginal bleeding and pelvic pain. Evaluation is especially important in postmenopausal women with a history of pelvic surgery. In some cases, surveillance after pelvic surgery may prevent rupture, evisceration, and incarceration.
