Surgical repair of vulvar anus in adults.

Three adult women with previously unoperated vulvar anus underwent surgical treatment for faecal incontinence which developed in adulthood. The obvious cause of incontinence in these patients was the weakening of pelvic floor musculature by aging and pregnancy. Two of the patients had several associated anomalies. The anus was transposed to the normal perineal position through the well-developed external sphincter found posterior to the vulvar anus. Faecal continence improved markedly in all patients.
