Abstract
Tow cases of vesicosigmoidal fistula due to the diverticulitis of the sigmoid colon are reported. The first case is a 55-year-old man. He was admitted to the hospital because of cloudy urine. Barium enema showed diverticulosis of the sigmoid colon and a fistula from the sigmoid colon to urinary bladder. Primary resection of the sigmoid colon and wedge resection of the bladder were performed. The second case is a 74-year-old woman. She was admitted because of fecaluria. Cystoscopy, cystography and colonoscopy could reveal no colonovesical fistula, but barium enema showed diverticulosis of the entire colon and a fistula from the sigmoid colon to urinary bladder. Left hemicolectomy, wedge resection of bladder, drainage of retroperitoneal abscess due to diverticulitis of the desending colon, and cholecystectomy were carried out. Post operative were unevenful in both cases.
One-hundred and ten cases of colonovesical fistula due to diverticulitis of the sigmoid colon reported in the Japanese litarature are also reviewed.
