The importance of endoscopy in the diagnosis of small intestinal tumors was evaluated
in 15 patients with small intestinal tumors treated in our hospital. Two tumors were
benign, and 13 were malignant (carcinoma in 5 patients, malignant lymphoma in 5 and
leiomyosarcoma in 3). The presence of lesions could be determined by X-rays before
surgery, but definitive diagnoses were difficult. When preoperative endoscopy of the

intestinal endoscopes that are easier to insert
