Sigmoidovesicocutaneous fistula complicating diverticular disease of the colon.

A sixty-six year old diabetic male had a draining sinus tract from the lateral portion of a fourteen year old left herniorrhaphy scar. The diagnosis of sigmoidovesicocutaneous fistula was confirmed by a sinogram and the patient was treated in one stage with left hemicolectomy and resection of the fistula site from the dome of the bladder. To our knowledge this is the first report of a sigmoidovesicocutaneous fistula.
