CASE STUDY: MAJOR DUODENAL PAPILLA CANCER COMPLICATED BY ACUTE PARACANCROTIC NECROTIZING PANCREATITIS

The given paper describes a case of treating adenocarcinoma of the papilla of Vater diagnosed as the cause after an episode of acute pancreatitis. The etiology of aсute pancreatitis was considered idiopathic until the onset of complaints caused by tumor growth. The volume of radical surgery has changed intraoperatively due to the detection of infected limited necrotic clusters, didn't diagnosed both laboratory and instrumentally. Pathomorphological conclusion: considering clinical data, low-grade (G3) adenocarcinoma of the major duodenal papilla, which developed from pre-existing tubular villous adenoma of the duodenum or intraampullary papillary neoplasia (IAPN). Predicting the early detection of MNPs after AP episode requires further research by improving imaging techniques, introducing new non-invasive techniques and investigating circulating biomarkers. The scope of surgery for patients with clinically significant complications of tumor growth and identified competing diagnosis at the target site should be individually decided and weighed. Infected pancreatitis in the late stages requires careful diagnosis.
