Dynamic aspects of gastric emptying in patients with peptic ulcer according to ulcer stages.
The pattern and the time of gastric emptying were investigated in 38 patients with peptic ulcer and 7 healthy volunteers using the double-sampling method. The pattern of gastric emptying assumed the following three attitudes, that is, exponential (44%), quadratic (29%) and unclassified (27%) pattern. These patterns appeared to depend on the distance from the gastric angle to the pyloric ring measured from X-ray pictures in the upright position. There was no significant difference in the gastric emptying time in patients with peptic ulcer according to its site. During follow-up observations of the same case, the gastric emptying time had a tendency to shorten in patients with duodenal ulcer while it showed no definite variation in patients with gastric ulcer.
