Endoscopic Retrograde Cholangiopancreatography Clinical Trial
Official title:
Application of Endoscopic Scissors Cutting Endoscopic Nasobiliary Drainage Tube in the Treatment of Malignant Hilar Biliary Strictures: a Multicenter, Prospective, Randomized Controlled Study
The purpose of this study is to evaluate application value of the endoscopic cutting technique in the treatment of malignant hilar biliary strictures.
The management unresectable malignant hilar biliary strictures is still very difficult in spite of the rapid development of new endoscopic devices.The application of stent (plastic or metallic) has allowed us to achieve successful drainage. However,there are many complications related to the placement of stents,such as cholangitis,high rate of re-intervention,and so on. The application of endoscopic cutting technique is considered to reduce these complication. ;
