ERC is mainly used either for the investigation of extrahepatic cholestasis or for the evaluation of common bile duct stones. Contrary to non-invasive procedures in liver diseases (laboratory investigation, ultrasound, computer tomography), ERC is only indicated when the biliary system might be involved in the underlying process. In these cases application of ERC depends on the question whether optimal visualization of the biliary tree will further assist in the therapeutic management of the disease. In primary and secondary sclerosing cholangitis ERC is the diagnostic procedure of choice.
内镜逆行胰胆管造影（ERC）主要用于肝外胆汁淤积的检查或胆总管结石的评估。与肝脏疾病的非侵入性检查方法（实验室检查、超声、计算机断层扫描）不同，只有当胆道系统可能参与潜在疾病过程时才会使用ERC。在这些情况下，ERC的应用取决于胆道树的最佳可视化是否会进一步有助于疾病的治疗管理这一问题。在原发性和继发性硬化性胆管炎中，ERC是首选的诊断方法。
