Abstract

Background: increased pressure on healthcare systems and possible risk of nosocomial COVID-19 infection during pandemic urged many guidelines to severely restrict the number of operations. The aim of this study was to investigate the risk of COVID-19 infection and its complications in patients undergoing urgent or elective operations. Methods: a prospective observational cohort study was conducted in a tertiary surgical center and all patients with no preoperative history of COVID-19 undergoing elective or emergent surgeries were included in this investigation. chest computed tomography (CT) scan or polymerase chain reaction (PCR) test were performed on patients before and after surgery. Results: 183 patients who underwent an operation were enrolled in this study. In postoperative follow-up, 12 patients were positive for COVID-19 infection as identified by RT-PCR and non-contrasted chest CT scans. Regrettably, 2 individuals passed with one of these individuals dying as a direct result of COVID-19 infection. All the 12 cases of post-operative COVID-19 patients underwent elective surgeries. Conclusion: the gathered results indicate a need for the re-evaluation of the risks of operation during the COVID-19 pandemic. If operations are performed while observing protective and preventative protocols, the risk of post-operative nosocomial COVID-19 is significantly reduced. Hence, the consequences imposed on patients by the delay or cancellation of operations (most notably in cancer cases) may outweigh the risk of post-operative COVID-19 infections. © 2022
