Measurement of gastric emptying in non-ulcer dyspepsia]

Using real-time ultrasonography, we monitored gastric emptying indirectly in 26 cases of non-ulcer dyspepsia (NUD) and 13 healthy adults by determining the anteroposterior gastric measurement of a single section of the stomach in the corpus fundus immediately after drinking 500 ml water and then every 10 min. for five times. The average time for 50% gastric emptying in NUD patients (36.46 +/- 13.13, x +/- s) was longer than that in healthy adults (23.54 +/- 5.93), but the half time of gastric emptying in male with NUD was not significantly different as compared with that in male controls and female patients of NUD.
