Abstract
A 44-year-old man was admitted to the hospital because of abdominal pain and abdominal fullness. Barium enema showed proctosigmoid stenosis ; based on the suspicion of ileus caused by colon cancer, we constructed an artificial anus. Postoperatively, the urine became turbid with a fecal smell, and cystography showed a rectovesical fistula. Biopsies of both the rectum and bladder were negative for carcinoma. Since the rectal stenosis did not appear to improve, we performed anterior resection and partial cystectomy. A diagnosis of rectal stenosis with rectal diverticulitis and rectovesical fistula was made based on histopathological examination of the resected specimens. A literature search for rectal stenosis caused by diverticulitis yielded 5 case reports, however, none had an associated rectovesical fistula ; thus, we believe that ours is a rare case worthy of reporting.
