Until now, X-ray examination has been the main procedure for the diagnosis of small intestinal disease. Since the new methods―double-balloon endoscopy(DBE)and capsule endoscopy―have been used the diagnostic procedure for the small intestine is presently changing. The methods mentioned above are especially useful for the diagnosis of gastrointestinal bleeding of small intestinal disease. DBE was performed on 25 patients, on 39 occasions in our hospital. The source of bleeding was identified in 11(44 %)of 25 patients. It was only in one case that the cause of the bleeding was a small intestinal tumor. Thus, it is an uncommon clinical condition, but diagnosis of small intestinal tumors is often delayed because of insufficient examination. The incidence of the symptom and objective sign due to small intestinal tumors varies according to their types. We described four types of tumors(primary adenocacinoma, malignant lymphoma, Gastrointestinal stromal tumor, lipoma)whose frequency was comparatively high. The frequency of gastrointestinal bleeding and other clinical features of these disease were recorded.
