Colovaginal fistula secondary to diverticular disease.

Colovaginal fistula is infrequently encountered in gynecologic practice, but, when it does occur, diverticular disease is the most common cause. This paper discusses current concepts in etiology, diagnosis, and treatment of patients with colovaginal fistula secondary to diverticular disease. Review of the literature reveals that a majority of patients have a history of hysterectomy and are primarily diagnosed by barium enema. The current trend in treatment is surgical correction with primary resection and anastomosis.
