Accuracy of ASGE high-risk criteria in evaluation of patients with suspected common bile duct stones

Although ASGE high-risk criteria demonstrated >50% probability of the patient having choledocholithiasis, more than a third of the patients would receive diagnostic ERCPs. Criteria with choledocholithiasis on abdominal US and/or bilirubin levels >4 mg/dL plus a dilated CBD showed higher specificity and positive predictive value.
