[Anatomo-stereologic characteristics of the mucous membrane of the major duodenal papilla].
In 55 men and 60 women who had had not any pathology in their biliary-pancreato-duodenal system during life, microrelief of the mucous membrane in the major duodenal papilla has been studied by means of light and scanning electron microscopy. It is defined by variants of fusion of the common bile duct and the pancreatic duct in the papilla. Three main variants of the ducts fusion are defined and, respectively, three main varieties of the structure of the mucous membrane folds. When the ducts flow into the same orifice separately, the mucous membrane relief is even, parvigranular and there are no fold-valves. In the common major duodenal papilla, the architectonics of the mucous membrane resembles the valve that acts as a block-outlet mechanism.
