A CASE OF MALIGNANT LYMPHOMA OF THE MIDDLE SMALL INTESTINE PREOPERATIVELY DIAGNOSED BY PERORAL ENTEROSCOPY

Abstract

Few cases of malignant tumor of the small intestine diagnosed preoperatively have been reported, in spite of the developement of endoscopic examination. We experienced one case of malignant lymphoma located 220cm distal to the Treitz Ligament. A patient was admitted to our hospital with a chief complaint of abdominal fullness. The diagnosis of malignant lymphoma could be made preoperatively by peroral enteroscopy under a sliding tube guidance, and was confirmed by histologic examination. This was the case most distally located from the Treitz ligament among the cases of malignant tumor of the small intestine diagnosed preperatively. Peroral enteroscopy is the most useful procedure in the preoperative diagnosis for small intestinal malignant tumors.
