In a retrospective record review of 76 patients diagnosed with enterovesical fistula over a 12-year period, the complication rate in those treated with single-stage repair was not statistically different from that in patients who underwent multistage repair. [71]

In general, the overall outcome and prognosis are excellent in patients with non–radiation-induced or cancer-induced fistulae. Such patients usually respond well to resection of the diseased colon and have no significant urinary sequelae.

The prognosis in patients with colon carcinoma and fistulization is less favorable because the involvement of the bladder usually heralds a more aggressive tumor that often is metastatic at the time of detection.

Radiation-induced fistulae are more likely to recur, but the long-term patient prognosis may be better if the malignancy for which the radiation was administered has been controlled.

Reported outcomes of laparoscopic surgery for enterovesical fistulas has been limited to small series and observational studies, with conversion rates that range from 0%-36%. Larger studies are needed to determine the saftey and efficacy of this approach. [72]
