[Surgical papillotomy, endoscopic-manometric and clinical results (author's transl)]

4--9 years after transduodenal papillotomy an endoscopic-manometric and clinical control of the surgical result was done in 49 patients. The pressure difference of common bile duct and duodenum was of great interest. There existed a correlation between the pressure difference and other parameters so far, as air was frequently seen in those patients without pressure gradient between common bile duct and duodenum. Pathological activity of gamma-GT and a decrease of Prothrombine-time was found after a high pressure difference. It may be possible that anatomical variations of the biliary system and the duodenum have some importance for the formation of stones.
