O. Konle et al., CHRONIC NAUSEA AS THE LEADING SYMPTOM - AN INDICATION FOR DOUBLE-CONTRAST EXAMINATION OF THE UPPER INTESTINAL-TRACT FOLLOWING NORMAL GASTROSCOPY, Zeitschrift fur Gastroenterologie, 31(7-8), 1993, pp. 444-446
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.
