The diagnostic accuracy of endoscopic ultrasound in suspected biliary obstruction and its impact on endoscopic retrograde cholangiopancreatography burden in real clinical practice

Abstract

EUS demonstrated high diagnostic accuracy in this mixed group of PBD. This accurately guided ERCP need and avoided unnecessary ERCP in 36%. EUS and ERCP in the same endoscopic session for the evaluation and management of PBD is technically feasible, with safety and efficacy profiles equivalent to that of each procedure performed independently in different sessions.
