Enterovesical fistula: 10 years experience.
BACKGROUND
Enterovesical fistula is a relatively uncommon complication of pelvic malignancies, diverticulitis of the colon, postoperative irradiation or trauma. Early diagnosis of enterovesical fistula is difficult and its management, complicated. The main purpose of this study is to investigate the most appropriate diagnostic method and to discuss the choice among different surgical managements.


METHODS
From 1986 to 1995, 30 patients with enterovesical fistula were diagnosed and treated at Veterans General Hospital-Taipei. The records were reviewed retrospectively with regard to symptoms, primary disease process, diagnostic studies, management, complications, mortality and follow-up.


RESULTS
Recurrent urinary tract infection (UTI) accounted for 73% and was the most common presenting symptom. Fecaluria (43%) and urine per rectum (40%) were another two common presenting symptoms. The major cause of these cases was malignancy (36%), followed by postoperative radiotherapy (17%) and iatrogenic injury (17%). Most of these cases were diagnosed by cystography (90%), barium enema (75%) or cystoscopy (69%). The rectum (52%) was the most common site involved, followed by the sigmoid colon (39%). The surgical management was individualized for each patient according to the general condition and the disease process.


CONCLUSIONS
By combining the results of cystography, barium enema and cystoscopy, diagnosis of enterovesical fistula can be established in almost all cases. Single-stage operation for enterovesical fistula should be limited to those patients in good nutritional state and without severe inflammation, radiation injury, intestinal obstruction, other major medical problem, advanced malignancy or old age.
