Important role of acute care surgery during pandemic time

Pandemic impacts acute care surgery for diseases, such as gallbladder disease and acute appendicitis. At the early stage of coronavirus disease 2019 (COVID-19) pandemic, the case number of patients needing surgery decreased in hospitals from different countries. This decline was associated with the stay-home order and fear of getting COVID-19 infection. However, recent reports show that the case number for acute surgery returns to the normal level, which is comparable to that before the beginning of the pandemic. In addition, a variety of diseases show more severe than the cases before the pandemic, which might be caused by factors such as lack of regular follow-up and screening diagnosis and infection of viruses.
