[Changes in the biliary tracts in various phases of the course of peptic ulcer before and after gastric resection].

By means of serial intravenous cholegraphy, oral cholecystography and the combined investigation of the stomach and gallbladder the state of the bile passages was examined in 157 patients with ulcerous diseas before and after gastric resection. Many patients (52.4%) with ulcerous disease showed congenital and acquired deformity of the gallbladder, some patients (7.6%)--adhesive deformity of the common hepatic and common bile ducts. In most patients functional (mainly the decreased concentration capacity and hyperkinetic dyskinesia) changes in the gallbladder were noted.
