The effect of alterations in the biliary tract on the gastric milieu was evaluated in gallstone disease and after cholecystectomy or biliary fenestration and compared with a control group. Endoscopic bile reflux was often found in gallstone patients (67%) and almost always after cholecystectomy (89%). Gastric bile acid concentrations were greater in the gallstone patients than in the control patients, were higher still after cholecystectomy, and were highest after biliary fenestration. The pH of the gastric fluid was more alkaline in the cholecystectomized groups. Lysolecithin concentrations were generally low and did not differ between the groups, nor was there any difference in scintigraphic reflux between the groups. Endoscopic erythematous gastritis correlated with the grade of bile reflux and was a common finding after biliary tract procedures. There were no consistent histologic findings associated with duodenogastric reflux. Helicobacter pylori colonization rates were similar in the various patient groups and were not affected by the reflux grade.
