抄録

A 57-year-old man with a history of undergoing an operation for acute appendicitis at the age of 45 was seen at the hospital because of abdominal pain. Abdominal plain x-ray examination revealed small intestinal gas. Adhesive ileus was suspected and a long tube was inserted for the treatment but no symptomatic remission was attained. Abdominal CT scan offered findings suggestive of intussusception. Colonofiberscopy showed that the ileum was prolapsed into the lumen of the ascending colon which was led by an elevated lesion. Intussusception caused by the small intestinal tumor was diagnosed and an ileocecal excision under laparotomy was carried out. On the excised material a type Ip elevated lesion was identified in the ileum 15 cm proximal to the ileocecal valve. The histological diagnosis was well differentiated adenocarcinoma with adenoma components. The cancer lesion was localized in the lamina propria mucosae and no lymph nodes were involved.<br> Early cancer of the small intestine is a rare entity. We report this case, together with some bibliographical comments including recent reported cases.
