SUMMARY
Surgical treatment was applied in 145 patients with complicated forms of chronic pancreatitis (CP) at the department of surgery of the Ivano-Frankivsk Regional Clinical Hospital in 2009–2016. Fourty-nine (33.7 %) patients had symptoms of biliary hypertension (BH); in five (3.4 %) of them BH was combined with chronic duodenal obstruction (CDO), the other 5 (3.4 %) patients had a combination of BH+CDP and local venous hypertension of pancreaticobiliary area vessels. Resection-type surgeries were applied in 28 (57.1 %) patients with CP complicated by BH. Intraoperative monitoring of biliary pressure was used in 17 patients in the process of duodenum-preserving resections of the pancreas. Frey’s procedure was applied to 20 (71.4 %) patients, in whom BH persisted after the resection stage of the surgery; Frey’s procedure was supplemented by interventions on bile ducts: hepaticoenteroanastomosis was applied in 12 patients, excision of pancreas lingula was applied in one patient, internal biliopancreatic anastomosis was applied in one patient. Berne modification was used in 2 (7.2 %) patients, and pancreaticoduodenal resection (PDR) according to Whipple – in 6 (21.4 %) patients. Remote results were studied in 19 (67.8 %) patients. Patients after duodenum-preserving resections had the best quality of life indicators, for BH signs were absent.
