Diagnostic Accuracy of Endoscopic Ultrasonography Versus the Gold Standard Endoscopic Retrograde Cholangiopancreatography in Detecting Common Bile Duct Stones

Abstract Background and objectives Stone in the biliary tract is one of the most common causes of hospitalization. However, it is difficult to determine the prevalence of gallstones in the general population because they are often asymptomatic. Thus, management lies in the proper clearance of the common bile duct (CBD) along with the removal of the gallbladder, for which it must be diagnosed on time with proper accuracy. Imaging modalities including magnetic resonance cholangiopancreatography (MRCP), endoscopic ultrasound (EUS), and endoscopic
