Gastric emptying of combined liquid-solid meals in healed duodenal ulcer.

The gastric emptying rates of combined liquid and solid radioisotopically labeled meals in 47 healed duodenal ulcer subjects and 17 healthy control subjects are compared. No significant differences were found between the groups in emptying slopes and the emptying half-times or in the percent retention values at any of the counting intervals for either the liquid or solid meals. These results are compatible with the observation that the rapid gastric emptying in many patients with duodenal ulcer is associated with the disease and that healing results in a return to normal gastric emptying rates. However, since gastric emptying rates during active ulceration were not determined in our patients, a more definitive interpretation awaits a study comparing emptying rates obtained during and after healing of active ulceration in the same patient.
