Efficacy of endoultrasonography application in conditions of moderate risk for choledocholithiasis occurrence was estimated in 33 patients, in whom ultrasonography (US) did not reveal the common biliary duct concrements. Sensitivity, specificity, accuracy, positive and negative prognostic values of the method in suspicion for choledocholithiasis presence while US performance have had constituted 78.6, 94.7, 82.0, 98.2 and 54.5%; vs for endoultrasonography--100, 94.4, 97, 93.8 and 100% accordingly. Endoultrasonography constitutes a safe and highly effective method of investigation in patients in suspicion of the biliary ducts disease presence, it permits to reveal choledocholithiasis in significant part of patients after ineffective US. This diagnostic option permits to reduce the need for performance of diagnostic endoscopic retrograde cholangiopancreaticography.
对33例超声检查（US）未发现胆总管结石的患者评估了内镜超声检查在胆总管结石发生中度风险情况下的应用效果。该方法在US检查怀疑存在胆总管结石时的敏感性、特异性、准确性、阳性和阴性预测值分别为78.6%、94.7%、82.0%、98.2%和54.5%；而内镜超声检查相应的值分别为100%、94.4%、97%、93.8%和100%。内镜超声检查是一种安全且高效的检查方法，适用于怀疑存在胆管疾病的患者，它能在US检查无效后的大部分患者中发现胆总管结石。这种诊断方法可减少诊断性内镜逆行胰胆管造影的需求。
