ABSTRACT
Objective To evaluate the efficacy of different methods in preventing pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP).Methods Databases including PubMed,EMBASE,Cochrane Library,Chinese Journal Full-text Database,China Biomedicine Database were searched with key words including endoscopic retrograde cholangiopancreatography,ERCP,post-ERCP pancreatitis,pancreatitis,pancreatic duct stent,non-steroid anti-inflammatory drugs,indometacin,diclofenac,protease inhibitors,nafamostat,ulinastatin,gabexate,somatostain,内镜逆行胰胆管造影,内镜逆行胰胆管造影术后胰腺炎,胰腺炎,胰管支架置入,非甾体类抗炎药,吲哚美辛,双氯芬酸,抑酶剂,萘莫司他,乌司他丁,加贝酯and生长抑素.Literatures published between January 2000 and January 2014 were searched.Randomized controlled studies on prevention of pancreatitis after ERCP which were enrolled in this study were analyzed by 2 independent reviewers.The quality of the literatures was evaluated.All data were analyzed using the RevMan 5.0 software.Data were expressed in odds ratio (OR) and 95％ confidence interval (95％ CI).The heterogeneity of the studies was analyzed using the I2 test.Results Twenty-seven literatures were enrolled in the study.There were 4 701 patients in the experimental group (including patients who were treated by pancreatic stent installation,non-steroidal antiinflammatory drugs,nafamostat,ulinastatin,gabexate,intravenous infusion of somatostain for more than 6 hours,intravenous infusion of somatostain for less than 6 hours,bolus injection of somatostain) and 3 592 patients in the control group (including patients treated without pancreatic duct installation or placebo).The results of Meta analysis showed that pancreatic stent installation,non-steroid anti-inflammatory drugs,nafamostat,intravenous infusion of somatostain for more than 6 hours and bolus injection of somatostain could significantly decrease the incidence of pancreatitis after ERCP (OR =0.18,0.45,0.31,0.33,0.25,95％ CI:0.09-0.35,0.33-0.61,0.19-0.52,0.20-0.56,0.11-0.55,P ＜ 0.05).Conclusion Pancreatic stent installation,non-steroid anti-inflammatory drugs,nafamostat,intravenous infusion of somatostain for more than 6 hours and bolus injection of somatostain could effectively prevent the incidence of pancreatitis after ERCP.
