Stent implantation is an effective approach for palliative treatment of Bismuth-Corlette type III–IV malignant hilar biliary obstructions (MHBOs). In this article, we reviewed the currently used access methods for biliary stent placement (percutaneous transhepatic biliary drainage, endoscopic biliary drainage, endosonography guided biliary drainage), the available stent types (plastic stent, self-expanding metallic stent, full cover self-expanding metallic stent, radioactive self-expanding metallic stent), major approaches (unilateral, bilateral) and deployment methods (stent-in-stent, stent-by-stent). Finally, this review gives an outlook on perspectives of development in stenting and other palliative methods in MHBO.
支架植入是治疗Bismuth-Corlette III–IV型恶性肝门部胆道梗阻的有效姑息疗法。本文系统综述了当前胆道支架置入的常用入路方式(经皮肝穿刺胆道引流、内镜下胆道引流、超声内镜引导下胆道引流)、现有支架类型(塑料支架、自膨式金属支架、全覆膜自膨式金属支架、放射性自膨式金属支架)、主要布放策略(单侧引流、双侧引流)及支架释放技术(支架套叠法、并列支架法)。最后,本文对恶性肝门部胆道梗阻支架治疗及其他姑息疗法的发展前景进行了展望。
