title: Metastatic adenocarcinoma from the lung occurring as occult gastrointestinal bleeding.

Most small bowel metastatic tumors of various primaries are asymptomatic and are usually diagnosed at emergency operation. Since the prognosis is generally poor, operative resection should be conservative.
