Core Tip

Core tip: Recognizing risk factors for endoscopic retrograde cholangiopancreatography (ERCP)-related complications is essential to reduce adverse events (AEs). There are limited data evaluating ERCP outcomes in renal disease. In a retrospective cohort study using the Nationwide Inpatient Sample 2011-2013 and including 492175 discharges, we compared inpatient ERCP AEs, mortality and length of stay between patients with and without renal disease. We found end-stage renal disease (ESRD) to be associated with higher post ERCP pancreatitis [8.3%, adjusted odd ratio (aOR) = 1.7, aP < 0.001], bleeding (5.1%, aOR = 1.86, aP < 0.001), mortality (7.1%, aOR = 6.6, aP < 0.001) and longer hospital stay (5.9 d, aP < 0.001). Physicians should consider special interventions in ESRD patients to decrease ERCP AEs.
