The coronavirus disease 2019 (COVID-19), caused by a coronavirus SARS-CoV-2, infects a large part of our population. In surgical patient's COVID-19 can cause a quick deterioration of lung function.[1–3] In addition to a lung disorder, an alteration in other organs can occur and increase mortality.[4–6]

Based on clinical information and expert recommendations, it is suggested that for patients with a possible COVID-19 infection, elective surgeries may be canceled or postponed with the focus to only maintain emergency operations and elective cancer surgeries.[4–10] Some authors obtained that the time of surgery for a patient who has suffered from SARS-CoV-2 should be delayed up to at least 7 weeks after passing the infection.[11]

To reduce the mortality rate and postoperative pulmonary complications (PPC) we have included the patients who underwent surgery on post-COVID-19 patients when the infection had disappeared, there were no symptoms, and the laboratory testing for SARS-CoV-2 infection was negative. In these circumstances, since the patients included in our study suffered from the disease, residual lung lesions could be found despite being asymptomatic. Moreover, a lower incidence of PPC than that described in patients with active SARS-CoV-2 infection at the time of surgery could be expected.
