Impact of introduction of endoscopic ultrasound on volume, success, and complexity of endoscopic retrograde cholangiopancreatography in a tertiary referral center.

Background And Objectives: Endoscopic ultrasound (EUS) is commonly used to examine pancreaticobiliary disorders. We hypothesize that the introduction of EUS service may change the pattern and the complexity of endoscopic retrograde cholangiopancreatographies (ERCPs) performed. The aim of this study is to assess the impact of introducing EUS on the volume, success, and complexity of ERCP.
