CHRONIC NAUSEA AS THE LEADING SYMPTOM - AN INDICATION FOR DOUBLE-CONTRAST EXAMINATION OF THE UPPER INTESTINAL-TRACT FOLLOWING NORMAL GASTROSCOPY

We report a patient with chronic nausea as the leading symptom of a pr imary carcinoma of the duodenum located at the flexura duodeno-jejunal is. The tumour was not reached at gastroscopy, which was performed twi ce. Since this area usually cannot be seen upon gastroscopy or upon sm all bowel enteroclysma according to Sellink, a double-contrast investi gation of the upper gastrointestinal tract using a hypotonic agent sho uld be performed when nausea persists although gastroscopy is normal.
