ASGE指南：内镜下逆行胰胆管造影术（ERCP）在良性胆管疾病中的作用

ERCP was first reported in 1968 and was quickly accepted as a safe, direct technique for evaluating pancreaticobiliary disease.With the introduction of endoscopic sphincterotomy in 1974, therapeutic pancreaticobiliary endoscopy was developed. Over the past several decades, ERCP has evolved from a diagnostic procedure to one that is almost exclusively therapeutic. Other imaging techniques, such as abdominal US, CT, MRCP, EUS, and intraoperative cholangiography, provide diagnostic information that allows appropriate selection of patients for therapeutic ERCP.ERCP with cholangiopancreatoscopy is a useful adjunctive technique for the evaluation and management of biliary and pancreatic disease.
