We studied the long-term outcome after an anal sphincter tear.
From a cohort of 4569 women who gave birth in 1982 to 1983, we identified 445 (9.7%) who sustained a sphincter tear and 445 controls. Eighteen years after the delivery, we mailed them a questionnaire and graded fecal incontinence with the Wexner score, a summary of incontinence to flatus, liquid, or solid stools; need to wear a pad; and lifestyle alterations. We predefined severe incontinence as a score above 4 of 20.
Five hundred forty of 890 women (61%) returned the questionnaire. Severe fecal incontinence was reported by 34 of 259 women (13.1%) after a sphincter tear and 22 of 281 controls (7.8%) (risk ratio 1.7, 95% confidence interval 1.0 to 2.8). Only 6.4% of the reports of fecal incontinence were attributable to a sphincter tear.
Fecal incontinence is frequently reported, even by women who have not sustained an anal sphincter tear. Only a small fraction of fecal incontinence can be attributed to sphincter tears.
我们研究了肛门括约肌撕裂后的长期预后情况。
从1982年至1983年分娩的4569名女性队列中，我们确定了445名（9.7%）发生括约肌撕裂的女性以及445名对照者。分娩18年后，我们给她们邮寄了一份问卷，并使用韦克斯纳评分对大便失禁进行分级，该评分总结了对排气、液体或固体粪便失禁的情况；是否需要使用护垫；以及生活方式的改变。我们将严重失禁预先定义为评分高于20分中的4分。
890名女性中有540名（61%）回复了问卷。括约肌撕裂后，259名女性中有34名（13.1%）报告有严重大便失禁，281名对照者中有22名（7.8%）（风险比1.7，95%置信区间1.0至2.8）。只有6.4%的大便失禁报告可归因于括约肌撕裂。
即使是没有发生肛门括约肌撕裂的女性，也经常报告有大便失禁。只有一小部分大便失禁可归因于括约肌撕裂。
