[A case of widespread ileal stenosis caused by metastatic disseminated peritoneal carcinomatosis from lung cancer resected 8 years previously].

A 46-year-old man was admitted because of ileus. He had undergone an operation for lung carcinoma (stage IA) 8 years previously in another hospital. Because small bowel enema study showed widespread stricture of the ileum, we performed an operation. During the operation we diagnosed metastatic small bowel carcinoma. Because the resected sample of the small bowel carcinoma was similar to the lung carcinoma pathologically and detailed examination after the operation showed no other neoplasm, we considered this case to be small bowel metastasis of the lung carcinoma resected 8 years previously.
