The impact of the COVID-19 pandemic on acute appendicitis patients in a tertiary care center in Lebanon

With it becoming a global pandemic, the coronavirus disease of 2019 (COVID-19) imposed public health restraints that hampered patient’s presentation to hospitals. In Lebanon, little is known about the presentation patterns of acute appendicitis (AA) patients among different population groups during the COVID-19. Therefore, this study aims to assess the effects of the COVID-19 pandemic on the rates of cases seen during the pandemic period, the adopted management strategies, and evaluate the patient outcomes compared to presentations from previous years. This is a retrospective, observational cohort study with no interventional procedures. All patients presented to our tertiary health care center were diagnosed with AA between February 2019 and February 2021 comprised the study analysis. We divided our patients into the pre-pandemic period cohort March 1st, 2019, till February 29th, 2020, and the pandemic period cohort March 1st 2020 till March 1st 2021. We collected data retrospectively from 342 patients: 201 patients presented in the pre-pandemic period and 141 during the pandemic period. Male predominance was seen in both cohorts (51.7% and 58.9% respectively). A decrease in the number of AA cases was seen during the pandemic, however, the duration of symptoms before presentation was similar in both cohorts (p = 0.382) Additionally, the number of complicated appendicitis cases was not different between cohorts. The main imaging modality was CT in both groups with no statistically significant difference in the type of imaging between them (p = 0.398). Further, the predominant treatment modality remained surgery during the pandemic, with no difference between both periods (p = 0.200), and no statistically significant difference in the type of surgery performed as laparoscopic surgery remained the most common surgery type in the pandemic period (p = 0.43). Finally, no extra surgical and post-surgical complications were identified. In conclusion, our study is an example of how the COVID-19 pandemic did not significantly affect patients presenting for AA. Despite the COVID-19-related restrictions, Lebanese patients with worrying symptoms were presenting to the emergency department and the American University of Beirut Medical Center was providing them with the standards of care. Our study mirrors the Lebanese experience and gives an example of a population that focused more on their current symptoms than the fear of acquiring the COVID-19 virus. Further research is needed to assess whether this was the correct approach during these times.
