Abstract

Adenomas of the major duodenal papilla (MDP) are benign neoplasms with a high risk of malignancy, and therefore, regardless of the histopathological structure, they must be removed. Currently, both surgical and various intraluminal endoscopic interventions are used in the treatment of patients with MDP adenomas. To select the optimal method of treatment, endoscopic typing of MDP neoplasms is necessary, which provides for an accurate topical characterization of the tumor, taking into account the size, growth, and spread to the walls of the duodenum, the terminal sections of the common bile duct and the main pancreatic duct. The endoscopic classification of neoplasms of the major duodenal papilla developed by us allows us to determine the most effective and safe method of surgical intervention for each type of tumor.
