[Papillomatosis of the opening of the major duodenal papilla in chronic, recurrent pancreatitis (based on surgical biopsy data)].
Examinations of 55 major duodenal papillas (MDP) amputated in patients with chronic relapsing pancreatitis revealed papillomatosis of the opening zone in 20 (36%). Papillomatosis developed when the pancreating and bile ducts discharged into the duodenum separately at the top of MDP without forming an ampoule. Papillomatosis was manifested by fibrous-epithelial papillar hyperplastic outgrowths representing pathologically altered folds of the MDP mucous membrane. The features of changes in papillary outgrowths were shown to include circulatory disorders, lympho-plasmocytic infiltration of the stroma, adenomatosis, etc. The causes of papillomatosis development and its association with chronic relapsing pancreatitis are discussed.
