Accuracy of ASGE criteria for the prediction of choledocholithiasis

I read with interest the article "Accuracy of ASGE criteria for the prediction of choledocholithiasis" by Nárvaez et al. Patients with suspicion of choledocholithiasis (CL) were categorized according to the American Society for Gastrointestinal Endoscopy (ASGE) recommendations. Those patients classified into high or intermediate-probability for CL underwent an endoscopic retrograde cholangiopancreatography (ERCP) without any further non-endoscopic biliary imaging modalities. In the ASGE recommendations for intermediate risk CL patients, they mention options for the evaluation of these patients including endoscopic ultrasound (EUS) and magnetic resonance cholangiography (MRC).
