Sigmoidovaginal fistula secondary to diverticular disease. A report of three cases.

ABSTRACT

Colovaginal fistula from any cause is rare. Diverticular disease is the most common cause. We treated three women for sigmoidovaginal fistulae secondary to diverticular disease. These 3 cases bring the total number reported to 49. Diagnosis of these fistulae may be difficult, and controversy exists over which form of surgical management should be employed. Since more women are living to an age at which diverticular disease is common, colovaginal fistulae probably will be encountered by the gynecologist with increasing frequency. Colovaginal fistula secondary to diverticular disease should be considered in the differential diagnosis when an elderly women complains of flatus vaginalis.
