In order to clarify endoscopic features of small intestinal disorders, the jejunal mucosa of 52 patients with various diseases was assessed by a push way method with a small intestinal endoscope (Olympus, SIF-B) and the results were as follows: 1) A successful insertion rate of the endoscope into the jejunum distal to Treitz's ligament was 93%. 2) Ten of 52 patients had a macroscopic lesion in the small intestine, that is, a case of jejunal reticulum cell sarcoma, a case of undifferentiated jejunal sarcoma, a case of smooth muscle cell sarcoma on the third and fourth portions of the duodenum, three cases of intestinal polyps, three cases of jejunal lymphoid hyperplasia and a case of α-chain disease. 3) Scattered white spots and white villi were found in 8 patients with protein-losing gastroenteropathy. A patient with alcoholic hepatitis, a patient with acute enteritis and a patient with short bowel syndrome had white villi on the jejunal mucosa. A patient with rheumatoid arthritis with diarrhea and a patient with IgG monoclonal gammanopathy had scattered white spots. 4) Erosions, redness, edema, and hypersecretion were observed on the jejunal mucosa of patients with cholera.
