Original Article


The present study was carried out to investigate the effect of several bile acids on tetragastrin-stimulated gastric secretion in dogs in which diversion of the biliary system was performed. Cholecystojejunostomy of the Roux-en-Y type was performed, along with the creation of a Heidenhain pouch (HP) and an external duodenal fistula. Gastric juice was collected from the HP and a mixture of bile acids and corn oil was administered through the duodenal fistula. Ursodeoxycholic acid (UDCA) and chenodeoxycholic acid (CDCA) exerted an inhibitory effect on gastric hypersecretion. Conjugated UDCA and several bile acids with different hydroxyl groups were also examined, and these bile acids also showed evidence of an inhibitory effect on the secretion of gastric juice, although there were no significant differences between them. Thus, it appears that all bile acids inhibit tetragastrin-stimulated gastric hypersecretion. This finding suggests that peptic ulcer disease can be prevented by the administration of bile acids to patients who undergo biliary diversion and are at a high risk for this postoperative complication.
