Core Tip

Core Tip: The advent of the coronavirus disease 2019 (COVID-19) outbreak has transformed the patterns of endoscopic activities. However, little is known about the clinical impact associated with COVID-19 on endoscopic retrograde cholangiopancreatography (ERCP). We compared the change in the number of ERCP procedures, causes, and clinical outcomes of emergency ERCP before (2018, 2019) and during the COVID-19 (2020) outbreak at a tertiary referral hospital in South Korea.
