Until recently, endoscopic retrograde cholangiopancreatography (ERCP) has been considered the gold standard for the diagnosis of and therapy in patients with suspected choledocholithiasis. However, the non-negligible complication rate of diagnostic and therapeutic ERCP has led investigators to identify different noninvasive diagnostic modalities. Endoscopic ultrasonography has been proved to be of great sensitivity (up to 97%) in the diagnosis of even tiny stones that can be easily masked by contrast medium during ERCP, without any procedure-related complications and with a negative predictive value reaching 100%, meaning that it can accurately and safely identify patients with choledocholithiasis, thereby avoiding inappropriate instrumental exploration of the common bile duct.
直到最近，内镜逆行胰胆管造影术（ERCP）一直被视为疑似胆总管结石患者诊断和治疗的金标准。然而，诊断性和治疗性ERCP不可忽视的并发症发生率促使研究人员寻找不同的非侵入性诊断方法。内镜超声已被证明在诊断即使是微小结石时具有很高的敏感性（高达97%），这些结石在ERCP期间很容易被造影剂掩盖，且无任何与操作相关的并发症，阴性预测值达100%，这意味着它可以准确、安全地识别胆总管结石患者，从而避免对胆总管进行不适当的器械探查。
