Background: Distributed antroduodenal motility plays an important rol e in the pathophysiology of functional dyspepsia (FD). Such motility disturbances can be investigated by transcutaneous ultrasound. When i t is measured in a standardized section, patients with FD have on an average significantly larger antral area than healthy controls. Metho ds: In this study we investigated the relationship between the antral area measured by ultrasound and the amount of fasting gastric conten t quantitated by aspiration through the gastroscope in 30 patients. I n five healthy controls we measured the increment of the antral area after ingestion of graded volumes of water. All recordings were made in interdigestive phase I. Results: M easurements of the antral area were highly reproducible, with small variations within an hour and fr om day to day. There was a highly significant correlation between ult rasonographica lly measured antral area and amounts of ingested water . Conclusions: The ultrasonographically measured antral area during f asting is highly reproducible. Enlarged fasting antral area re flects increased volume of gastric juice.
