Endoscopic retrograde cholangiopancreatography (ERCP) has become an important tool for the diagnosis and treatment of biliary tract diseases,with the development of technology and equipment.Hilar cholangiocarcinoma is the most common malignant neoplasm of the extrahepatic biliary system and many patients have lost the chance of surgical resection at the time of diagnosis.For the unresectable hilar cholangiocarcinoma,palliative treatment can be carried out by placing stents through ERCP or combining ERCP with intraluminal brachytherapy,photodynamic therapy and radiofrequency ablation,and for the resectable hilar cholangiocarcinoma,ERCP-related biliary drainage will be safe and effective if the preoperative biliary drainage is necessary.%随着内窥镜逆行胰胆管造影(ERCP)技术及设备的不断发展,ERCP目前已经成为了胆道系统疾病诊断及治疗的一种重要手段.肝门部胆管癌是肝外胆道系统中最常见的恶性肿瘤,被发现时许多患者已经失去了手术切除的机会.对于不可切除的肝门部胆管癌患者可通过ERCP技术放置胆道内支架行姑息性胆道引流术,也可通过ERCP联合腔内近距离照射治疗、光动力疗法、腔内射频消融等技术行姑息性治疗;对于可切除的肝门部胆管癌患者,如果需要行术前胆道引流,ERCP相关的胆道引流方式是一种安全、有效的手段.
