The records of 24 patients with enterovesical fistula treated at the urology sections of Telemark and Vestfold Central Hospitals are presented. Most fistulas were due to diverticulitis or a malignant tumor. The part of the intestine most frequently affected was the sigmoid colon in 14 patients, the rectum in 3, the cecum in 2 and the small intestine in 2. Of the 21 patients operated on, 12 underwent a one-stage procedure with resection of the fistula and primary anastomosis of the intestine. The postoperative course was uneventful for 16 patients. Recurrence of the fistula occurred in 1 patient. Three patients were conservatively treated. We recommend a one-stage operation for patients in a good general operating condition, with a well-organized fistula and no systemic infection.
