The research presents the results of surgical treatment applied to 530 patients with chronic pancreatitis (CP) between 1990 and 2022. The surgical interventions performed were: Roux-enhanced pancreatojejunostomy (PJA), cephalic duodenal pancreatectomy (DPC), thoracoscopic splanchnicectomy. For complicated cases with pancreatic pseudocyst (PP)- external drainage of PP, cystpancreaticojejunostomy (CPJA) on Roux loop. In cases of PC complicated with mechanical jaundice - pancreatojejunostomy (PJS) with cholecyst - or choledocho-jejunostomy (CoCJA) on bispiculated loop of Roux, CPJA with CoCJA on the splitted Roux loop. No postoperative lethality.
