Abstract

Common bile duct (CBD) stone is a common biliary disease in Korea and shows an increasing prevalence. Early and accurate diagnosis is necessary as complications such as acute suppurative cholangitis, acute pancreatitis, and septic shock can develop due to CBD stones. Clinical manifestations, laboratory findings, abdominal ultrasonography, and abdominal computed tomography are helpful for initial diagnosis of CBD stone. However, the presence of CBD stone is often unclear. Although endoscopic retrograde cholangiopancreatography (ERCP) is standard for diagnosis and treatment of CBD stone, it is invasive and associated with high rates of adverse events. Less invasive and accurate evaluation methods are necessary before ERCP. Endoscopic ultrasonography (EUS) and magnetic resonance cholangiopancreatography are both excellent diagnostic tools for detection of CBD stone, but recent meta-analysis showed the better diagnostic accuracy and sensitivity with EUS. The purpose of this review is to summarize the diagnostic tools and efficacy of EUS in diagnosing CBD stone.
