Research advances in hemorrhage after endoscopic retrograde cholangiopancreatography / 临床肝胆病杂志

ABSTRACT

Although hemorrhage after endoscopic retrograde cholangiopancreatography （ERCP） is mostly mild and self－limited， sometimes blood transfusion and endoscopic hemostasis are still needed. However， rebleeding may occur after conventional endoscopic hemostasis and thus requires interventional vascular embolization or surgical intervention， which might significantly increase the risk of death associated with post－ERCP bleeding. This article discusses the risk factors for post－ERCP bleeding， including disease－specific factors， patient－related factors， and operation－related factors， and elaborates on different measures for the prevention and treatment of post－ERCP bleeding， so as to provide a reference for identifying the high－risk population for bleeding and developing precise surgical strategies in clinical practice.
