Vesico-colic fistulae in the Grampian region: presentation, assessment, management and outcome.J R Coll Surg Edinb. 1997 Jun; 42(3):182-5.JR
Over a 12-year period, 67 patients presented with a vesico-colic fistula. The mean age was 69 years (range 19-96 years), with symptoms predominantly referred to the urinary tract. Cystoscopy and barium enema confirmed the presence of a fistula in 60 and 44% of patients respectively. A computerized tomography (CT) scan, used in only seven patients, revealed the fistula in each case. The underlying pathology included diverticular disease (62%), carcinoma (27%) and inflammatory bowel disease (6%). Fifty-one patients proceeded to surgery, of whom 32 (63%) had a sigmoid/recto sigmoid resection with primary anastomosis, and 13 (25%) a Hartmann's procedure. A diverting colostomy alone was employed to palliate cases of widespread carcinoma. No patient subsequently had the Hartmann's reversed. In addition to colonic resection, 48 (92%) patients had a simultaneous bladder procedure, varying from simple oversew in 32 (70%) patients to cystectomy and ileal conduit in three (6%). Wedge excision with primary bladder closure was practised in 12 (24%). Fistula recurrence occurred in seven (14%) patients, and the 30-day mortality was 10%. Surgery for vesico-colic fistula has an appreciable morbidity and mortality, yet if offers the only hope of achieving permanent symptomatic control.
