Abstract

Colonic diverticulosis has continuously increased, noticeably left-sided diseases, in Korea. A colovesical fistula is an uncommon complication of diverticulitis, and its most common cause is diverticular disease. Confirmation of its presence generally depends on clinical findings, such as pneumaturia and fecaluria. The primary aim of a diagnostic workup is not to observe the fistular tract itself but to find the etiology of the disease so that an appropriate therapy can be initiated. We present here the case of a 79-year-old man complaining of pneumaturia and fecaluria. On abdomen and pelvis CT, the patient was diagnosed as having a colovesical fistula due to sigmoid diverticulitis. After division of the adhesion between the sigmoid colon and the bladder, the defect of the bladder wall was repaired by simple closure. The colonic defect was treated with a segmental resection, including the rectosigmoid junction. The patient is doing well at 6 months after the operation and shows no evidence of recurrence of the fistula.
