The diagnostic yield of endoscopic ultrasonography in patients with suspected Choledocholithiasis

Background: Choledocholithiasis is the most common cause of biliary obstruction, which occurs in 10 – 20% of patients with cholelithiasis. Management of suspected choledocholithiasis requires confirmation of stones in the common bile duct (CBD). The diagnosis is based on clinical signs and symptoms, laboratory- and imaging examination findings. Likelihood of CBD stones can be prognosticated by the presence of various clinical predictors, however the sensitivity and specificity of these factors is moderate. Endoscopic ultrasonography (EUS) has been shown to be a non-invasive precise test for the detection of CBD…
