Gastric Emptying Rate in Gastric and Duodenal Ulceration

Abstract

The gastric emptying rate and the changes of the gastric contents 2 hours after intake of a liquid test meal have been investigated, using the method earlier described by Brömster et al. (1968). Patients with gastric ulcer had a significantly lower emptying rate than control subjects, whilst patients with duodenal ulcer did not differ significantly from the control subjects, though their emptying rate was faster. The changes of the gastric contents (pH, osmolarity and hydrochloric acid secretion) indicated that the quantities of gastric juice secreted were small in gastric ulceration.
