Pancreatitis is a common complication of endoscopic retrograde cholangiopancreatography( ERCP). Patient selection and risk factors assessment are critical elements for preventing post-ERCP pancreatitis(PEP). Pancreatic stent plays a role in prevention of PEP,but with limitations. Rectal administration of NSAIDs is an effective way to reduce the incidence of PEP. Effect of other drugs for preventing PEP is unclear. This article reviewed the advances in study on PEP.

Objective Toinvestigatetheriskfactorsforthedevelopmentofpost-endoscopicretrogradecholangiopancreatographypancrea-titisandhyperamylasemia(PEPH)afterendoscopicretrogradecholangiopancreatography(ERCP).Methods Theclinicaldataof233pa-tients who underwent therapeutic ERCP from January 2012 to December 2014 in our hospital and met the inclusion criteria were analyzed ret-rospectively.Basic information including age,sex,drinking history,single stone,triglyceride,and nationality was extracted,and detailed information on intraoperative procedure,intraoperative diagnosis,and complications for ERCP was carefully recorded.Chi-square test was applied for comparison of categorical data between groups,and Logistic regression analysis were applied to determine the risk factors for the developmentofPEPH.Results TheincidenceofPEPHwas26.6%(62/233).Univariateanalysisshowedthatfemalesex(χ2=3.320, P=0.045),drinking history (χ2 =6.108,P=0.010),common bile duct stenosis (χ2 =5.767,P=0.012),single stone (χ2 =9.121, P=0.020),juxta-ampullary duodenal diverticula (χ2 =28.170,P<0.001),and abnormal triglyceride (χ2 =54.717,P<0.001) might be the risk factors for PEPH,and these factors differed significantly between the two groups.Multivariate analysis showed that female sex (OR=1.616,P=0.025)drinking history (OR=2.360,P=0.010),common bile duct stenosis (OR=2.163,P=0.012),juxta-ampullary duodenal diverticula (OR=5.502,P<0.001),and abnormal triglyceride (OR=12.924,P<0.001)were independent risk fac-torsforPEPH.Conclusion Femalesex,drinkinghistory,commonbileductstenosis,juxta-ampullaryduodenaldiverticula,andabnor-mal triglyceride are independent risk factors for PEPH,and targeted preventive measures for such high-risk populations can effectively re-duce the incidence of PEPH.
