[2] [3] [4] [5] The described cases of cholecystitis in individuals with SARS-CoV-2 were postulated to be mediated by a dysregulated immune response to SARS-CoV-2 infection. [2] [3] [4] [5] Two cases reporting cholecystitis related to COVID-19 were at onset of COVID-19 symptoms, 2 but most cases described cholecystitis lagging COVID-19 diagnosis by at least 10-14 days or longer. [3] [4] [5] This timing later in the COVID-19 disease course supports an immune mediated mechanism triggering biliary pathology. 6 Gastrointestinal, hepatobiliary, and pancreatic manifestations of COVID-19 COVID-19 can mimic acute cholecystitis and is associated with the presence of viral RNA in the gallbladder wall COVID-19 with acute cholecystitis: a case report Acute acalculous cholecystitis on a COVID-19 patient: a case report Post COVID 19 acute acalculous cholecystitis raising the possibility of underlying dysregulated immune response, a case report COVID-19 illness in native and immunosuppressed states: A clinical-therapeutic staging proposal Multisystem inflammatory syndrome in children: A systematic review Case Series of Multisystem Inflammatory Syndrome in Adults Associated with SARS-CoV-2 Infection -United Kingdom and United States Multisystem Inflammatory Syndrome in Adults: Coming Into Focus Mean Time from Dx to Surgery All authors had full access to and take responsibility for the data reports.
