The most devastating pandemic of this era coronavirus disease-2019 (COVID-19) is caused by a novel virus named severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2). Although it is primarily a respiratory pathogen, it can also result in several extra-pulmonary manifestations includes gastrointestinal symptoms, hepatocellular injury. Angiotensin-converting enzyme-2 (ACE-2) receptor and transmembrane serine protease 2 (TMPRSS2), the entry receptor for the causative coronavirus SARS-CoV-2 is co-express in the gastrointestinal tract, hepatocyte, and cholangiocytes similar to the respiratory mucosa. The presence of these receptors facilitates the entry into the tissue and causes direct viral tissue damage, which is a proposed mechanism of injury. Diarrhoea, nausea, vomiting, abdominal discomfort are common gastrointestinal manifestations, whereas derangement of liver function tests is the most hepatic manifestation in COVID-19. In this article, we reviewed on SARS-CoV-2 disease COVID-19 regarding gastrointestinal, hepatic, and pancreatic manifestation, the mechanisms by which the virus may inflict damage, and their management perspective.
