COVID-19-associated acute appendicitis in adults. A report of five cases and a review of the literature

The novel coronavirus has negatively affected patients and healthcare systems globally. Individuals with coronavirus disease 2019 (COVID-19) experience a wide range of respiratory symptoms, from mild flu-like symptoms to severe and potentially fatal pneumonia. Some patients report gastrointestinal symptoms, such as nausea, vomiting and abdominal pain in addition to the respiratory symptoms or as a separate presentation. Even though abdominal pain syndrome indicates acute appendicitis, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection should be considered as a possible diagnosis during this pandemic. However, there have been reports of a few cases of acute abdominal pain revealing acute appendicitis associated with SARS-CoV-2 infection. Appendectomy is challenging in COVID-19-infected patients with acute appendicitis as it includes high surgical risks for the patients, as well as hazards for healthcare professionals who are exposed to SARS-CoV-2. The present study reports five cases of adult patients with COVID-19 with simultaneous acute appendicitis. In addition, the present study aims to provide the framework for the diagnosis and management of adult patients with COVID-19 with acute appendicitis.
