Endoscopic ultrasonography versus other diagnostic modalities in the diagnosis of choledocholithiasis.
Until recently, endoscopic retrograde cholangiopancreatography (ERCP) has been considered the gold standard for the diagnosis of and therapy in patients with suspected choledocholithiasis. However, the non-negligible complication rate of diagnostic and therapeutic ERCP has led investigators to identify different noninvasive diagnostic modalities. Endoscopic ultrasonography has been proved to be of great sensitivity (up to 97%) in the diagnosis of even tiny stones that can be easily masked by contrast medium during ERCP, without any procedure-related complications and with a negative predictive value reaching 100%, meaning that it can accurately and safely identify patients with choledocholithiasis, thereby avoiding inappropriate instrumental exploration of the common bile duct.
