[C. Controversial technical and methodological problems in abdominal surgery. 1. Bile: a) Procedures in intraoperative actualization of papillary stenosis. Papillotomy in principle].

A critical comment on the question of papillotomy en principe is made, based on results from more than 7000 gallbladder operations and over 500 papillotomies, performed at the surgical departments of the municipal hospitals in Braunschweig and Lüneburg. In principle, too few papillotomies are carried out in many hospitals. The duration and seriousness of the cholecystitis is to a large degree responsible for the frequency of the formation of a papilla stenosis.

[The significance of the duodenal papilla within the framework of diseases of gallbladder and bile ducts].

On the basis of 3185 biliary tract operations performed at the city hospitals of Braunschweig and Lüneburg, 12% of which included papillotomies, the frequency and pathogenesis of Vater's papilla stenosis is discussed. About 5% of all stenoses of Vater's papilla do not appear in connection with lithiasis in the biliary tract; these are defined as primary stenoses. 95% of Vater's papilla stenoses occur with lithiasis and inflammatory diseases of biliary tract.
