Perioperative management of non-deferrable oncologic surgeries during COVID-19 pandemic in Madrid, Spain. Is it safe?

Abstract

IntroductionSurgical treatment during Covid-19 pandemic is controversial. Currently, most clinical guidelines advise to defer surgical patients during the Covid-19 pandemic, although the supporting data is sparse. We assumed that a Covid-19-free hospital, on the back of strong isolation measures and targeted screening, could reduce complications and enable us to continue treating high-risk patients.MethodsProspective study with retrospective analysis of 355 patients who had undergone nondeferrable oncological surgery between March 16th, 2020, and April 14th, 2020, at our institution. The aim of the study was to assess the hospital restructuring and surgical protocols to be able to safely handle non-deferrable surgeries during the first wave of the Covid-19 pandemic. We implemented structural changes and an updated surgical-anesthetic protocol in order to isolate Covid-19 patients from other surgical patients. Comprehensive targeted screening for Covid-19 patients was made. PCR tests were requested for suspected Covid-19 patients. We analyzed mortality and complications related to both surgery and Covid-19 during hospital admission and also 15 and 30 days after surgery. We compared it with a sample of similar patients in the pre-pandemic period.ResultsOf the 355 patients enrolled in our study, 21 were removed due to Covid-19 infection, leaving a total of 334 patients in our final analysis. Post-operative complications were found in 37 patients (11.07%). Two patients died after surgery (0.6%). At the end of the study, Covid-19-related adverse outcomes were detected in six patients (1.79%). When comparing the complications of our original sample with the complications that occurred in the pre-covid era, we found no statistically significant differences.ConclusionsOur results show that the surgical treatment of oncologic patients during the Covid-19 pandemic is safe, as long as the hospital performs surgeries under strict isolation measures and a robust screening method. It is necessary to select Covid-19 free hospitals for this matter in this and future pandemics.
