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. Materials and Methods: This is a single-center retrospective data review of ERCP procedures done “before” and “after” the introduction of EUS (before EUS and after EUS). Patients' demographics, ERCP indications, types of sedation, therapeutic interventions, outcomes, complications, and complexity of ERCP were collected. The categorical and continuous variables were compared using Fisher's exact test and the unpaired t-test, respectively. Multivariable logistic regression analysis was used to compare ERCP outcomes. Results: A total of 945 ERCPs performed over a 3-year period between January 2010 and January 2013 (411 and 534 in the “before EUS” and “after EUS” time periods, respectively) were included in this study. There was a 30% relative increase in the volume of ERCPs after the introduction of EUS. ERCP success rate was higher after the introduction of EUS, even after adjusting the complexity grade [odds ratio (OR) = 4.54, P = 0.001]. Significant increase in the complexity of ERCP was observed after the introduction of EUS service. The OR of performing grade 4 ERCP was 4.44 (P = 0.0005) after the introduction of EUS. Conclusions: The introduction of a new EUS service in our tertiary referral university medical center is associated with an increase in the volume, success, and complexity of ERCP procedures. EUS expertise may be valuable for better ERCP outcomes.
