Carcinomas rarely occur at the site of a colostomy. A 73-year-old man underwent abdominoperineal resection (Miles' surgical procedure) for rectal carcinoma in September 1988. He did not return to the hospital until September 1995, when he was admitted with stricture of the stoma. Neither tumor nor ulcer was detected at the stoma. The tip of the doctor's little finger was able to pass through the stoma, and manual expanding alleviated the stricture. The patient did not return to the hospital again until August 1996, at age 81 years, when he visited the hospital because of complete stricture of the stoma. A biopsy revealed an adenomatous carcinoma, but the results of various examinations suggested no metastasis. A portion of the intestine, including the stoma and surrounding skin, was resected, and a new stoma was created in the descending colon. We report this rare carcinoma occurring at the site of a colostomy, and we review the literature.

Fistulojejunostomy was performed at the subcutaneous level in two patients with intractable pancreatic fistula that occurred after surgery for cancer of the ampulla of Vater and carcinoma of the lower bile duct. The treatment yielded mostly satisfactory results, though one patient incurred postoperative wound dehiscence, which was healed with conservative measures. Compared with conventional procedures, this method is technically easy to perform, as it does not involve surgical separation of the fistula up to a site deep within the abdominal cavity, rarely results in side injury, and poses few potential risks of cicatricial stenosis of the fistular lumen, because blood supply to the fistula is preserved. Subcutaneous fistulojejunostomy is considered to be recommendable for pancreatic fistulas that occur long after surgery and which are stenosed at the site of the pancreatojejunal stenosis and thus require surgical treatment.
