Gastric emptying of liquids in patients with peptic ulcer disease.

This study was designed to determine the rates of gastric emptying of water, saline and a 20% glucose solution in patients with gastric and duodenal ulcers. In all subjects, gastric emptying was fastest after administration of the saline, slower with water and the slowest with glucose. Significant statistical differences (p less than 0.05) in emptying rates between normal subjects and the group with duodenal ulcer were seen when water and saline but not glucose were used. We conclude that inhibitory effects of the osmotic receptors are not changed in gastric and duodenal ulcer patients. However, the emptying rates were higher when osmotic stimulus was withheld.
