Abstract
Ingestion of corrosive substances can lead to strictures of the esophagus and stomach. Cicatrization of the lower part of the esophagus can entrap vagal fibers in the process of fibrosis. The aim of the present study was to evaluate gallbladder dysfunction as a sequel to vagal damage in patients with corrosive-induced esophageal strictures. The cephalic phase of gallbladder emptying was stimulated by modified sham feeding according to the chew-and-spit method. Gallbladder volume was measured by ultrasonography using the ellipsoid method after an overnight fast and every 15 min for a period of 90 min after sham feeding in 22 patients and 10 controls. Mean fasting gallbladder volume was significantly greater in patients than in controls (22.09± 9.78 vs. 14.61± 4.42 ml;
