Gastrointestinal involvement in COVID-19 patients: a retrospective study from a Greek COVID-19 referral hospital.

Background: Much attention has been paid to the study and reporting of gastrointestinal (GI) symptoms in COVID-19 patients. Moreover, an increasing number of COVID-19 patients have been noted to experience hepatic and pancreatic injury. In this study, we retrospectively investigated symptoms and laboratory findings related to the GI system in a single center in Athens, Greece, and assessed the role of these parameters in relation to survival and disease severity.
