Abstract

A 62-year-old male was admitted to our hospital with an occipital bruise and abrasion. On the day after admission, he accidentally swallowed his partial denture. On abdominal X-ray the dentures were found to not have any sharp metal edges. Thus, the patient was followed carefully without therapy because the possibility of damage to the intestinal mucosa was considered to be low. The dentures were expected to pass spontaneously. However, the patient developed nausea and vomiting on the 7th admission day. Abdominal X-ray and CT were performed on the 8th admission day, and he was diagnosed as having a bowel obstruction caused by the denture. An emergency operation was performed. During the operation, a tumor on the upper ascending colon and the denture on its oral side were palpated. A radical resection of the colon cancer and removal of the bowel involved in the obstruction were performed.<BR>Examination of the resected specimen showed an invasion depth of SE, mild invasion to the lymphatic vessels and no lymph node metastasis. We present a rare case in which a laparotomy was performed to remove foreign body causing a bowel obstruction, and colon cancer was diagnosed incidentally.
