The small intestine was examined with the duodenal intubation method in 113 patients. Patients admitted with acute abdominal disease were not included. The frequency of positive findings was 22%, which exceeds that of previous years before the method was introduced. Eight per cent were found to have Crohn's disease. Thirteen patients were admitted for gastrointestinal bleeding, and in two of them the cause was found. All patients with uncharacteristic abdominal symptoms, were normal. The results and advantages of the method are discussed.
