| Abstract: | A 78-year-old woman had undergone radical cystectomy and construction of ileal conduit because of bladder cancer in 1988. Eighteen years after the operation, she was referred to our hospital with the chief complaint of abdominal pain and oliguria. She had a mass just superolateral to the stoma with tenderness and reddish skin. Abdominal X-ray and computed tomographic scanning showed free air and peristomal intestinal dilation in the subcutaneous area. With a diagnosis of incarcerated parastomal hernia and intestinal perforation, emergency operation was performed. The orifice of the hernia was located in the superolateral aspect of the stoma. The ascending colon was locally necrotic and perforated. Usually, the orifice of parastomal hernia is so wide that incarceration rarely occurs. Parastomal hernia treated with emergency operation is rare, with only 9 cases, including our case, reported in the Japanese literature. Three cases had ileal conduit, and the content of the hernia was the ascending colon only in our case. |
