Colonic Gangrene: A Sequela of Coronavirus Disease 2019

Initially considered to be a respiratory disease, coronavirus disease 2019 (COVID-19) is now recognized as a multisystem disease known to affect all the major organs, including the gastrointestinal system. Based on recent studies, severe acute respiratory syndrome coronavirus 2 causes dysregulation of multiple biological pathways, triggers an exaggerated immune response, and affects multiple organs. The gastrointestinal symptoms in COVID-19 are common but often overlooked. We report the case of a 50-year-old female with a recent history of COVID-19 presenting with complaints of abdominal pain and constipation. Initially, the patient was treated for respiratory symptoms and discharged home. Subsequently, she was re-admitted and diagnosed with colonic obstruction on radiology. Laparotomy revealed descending and sigmoid colonic gangrene requiring left colectomy. This case highlights the uncommon but severe gastrointestinal manifestations of COVID-19.
