ABSTRACT

Objective To investigate whether endoscopic nasobiliary drainage (ENBD) after endoscopic stone extraction could reduce post-operative complications.Methods Retrospective analysis of 697 patients with extrahepatic duct stones undergoing ERCP treatment was pedormed.They were assigned to ENBD group (n =538) and control group (n =159).Post-operative complications including pancreatitis,cholangitis and bleeding were observed and compared.Results There were no significant differences in incidence of pancreatitis and bleeding between 2 groups.Incidence of cholangitis in ENBD group was significantly lower than that in control group (1.3％ vs.3.8％,P ＜ 0.05).Conclusion ENBD after endoscopic stone extraction could reduce the incidence of postoperative cholangitis.
