Background. Endoscopic retrograde cholangiopancreatography (ERCP) is an important procedure in the diagnosis and management of pancreaticobiliary diseases. Post-ERCP pancreatitis (PEP) is the most common and serious adverse event after ERCP. Purpose – to evaluate retrospectively PEP incidence and to identify independent risk factors of PEP. Materials and Methods. The analysis of 578 ERCP cases was done. A number of potential risk factors for PEP were taken into uni- and multivariate analisys: age, gender, common bile duct (CBD) size, bilirubin level, presence of cholangitis, Sphincter of Oddi dysfunction (SOD), malignant biliary obstruction, chronic pancreatitis, biliary obstruction, history of cholecystectomy, history of endoscopic papillosphincterotomy (EPST), initial ERCP success, therapeutic success, selective biliary cannulation, pancreatic cannulation/injection, Precut and EPST. Results. PEP was in 29 (5%) cases. Six factors with р < 0,05 by univariate analysis (CBD ≤ 10 mm, normal bilirubin level, SOD, history of cholecystectomy, pancreatic cannulation/injection, precut) were included into multivariate logistic regression model. The independent risk factor for PEP were CBD ≤ 10 mm (OR 2,416; 95% ДІ, 1,037–5,629; p = 0,041), SOD (OR 4,107; 95% ДІ, 1,726–9,771; p = 0,001) та pancreatic cannulation/injection (OR 3,447; 95% ДІ, 1,455–8,166; p = 0,005); and precut was an independent protective factor for PEP (OR 0,129; 95% ДІ, 0,047–0,354; p = 0,014). Conclusions. The incidence of PEP was 5%. Small CBD and SOD are independent PEP risk factors as well as pancreatic cannulation/injection. Early precut technique is an independent factor preventing PEP.
