TWO CASES OF SIGMOIDOVESICAL FISTULA CAUSED BY DIVERTICULITIS OF THE COLON

Abstract

We report two cases of sigmoidovesical fistula caused by diverticulitis of the colon. Case 1 : A 71-year-old man was admitted to the hospital because of fecaluria. We diagnosed a sigmoidovesical fistula caused by diverticulitis according to the preoperative examination and managed with total parenteral nutrition. On the 19th day after admission, partial resection of the sigmoid colon and the bladder was performed. A sigmoidovesical fistula was verified on the macroscopic finding. There was no major problem during the postoperative course, but on the 15 postoperative day, interstitial pneumonia exacerbated and on postoperative day 42 the patient died. Case 2 : A 66-year-old man was admitted to the hospital because of fecaluria. We diagnosed a sigmoidovesical fistula caused by diverticulitis, and partial resection of the sigmoid colon and the bladder was performed. According to the macroscopic examination and findings, the fistula was obstructed. The postoperative couse was uneventful and the patient was discharged. We discussed especially the indication of operation for sigmoidovesical fistula using these two cases.
