ABSTRACT

Objective To discuss the clinical value of endoscopic retrograde cholangio panecreatography (ERCP) and endoscopic sphincterotomy (EST) for the treatment of extrahepatic bile duct stones. Metbods Forty-five cases were treated with ERCP and EST. Other 55 patients treated with opening proedure were selected to serve as the controls. Results The effective rate was 97.8% by ERCP and EST and 90.9% by opening procedure(P>0.05). The rate of residual stone was 2.22% by ERCP and EST and 20.00% by opening procedure(P<0.05). The rate of complications was 4.44% by ERCP and EST and 18.18% by opening procedure(P<0.05). Conclusion Therapeutic efficacy of ERCP and EST is better than the opening procedure in the treatment of extrahepatic bile duct stones. It is a safe, effective and simple method for the treatment of extrahepatic bile duct stones.
