Core Tip	This is the first East Asian report to be issued on the impacts of coronavirus disease 2019 (COVID-19) on emergent endoscopic activities and outcomes. This study demonstrated significant reductions in endoscopic procedures and changes in patient behaviors during the specific period (February 18 to March 28, 2020), from the start of the outbreak to the plateau of its exponential curve, in Daegu (South Korea), the worst-hit city, during the COVID-19 outbreak. We compared the changes in the numbers of endoscopic modalities and analyzed the causes and clinical outcomes of emergency endoscopies performed before (2018, 2019) and during the COVID-19 outbreak.
