Even after two years of pandemic, there are still uncertainties on how to proceed when we schedule endoscopic procedures. During the COVID-19 pandemic, some scientific societies recommended universal preprocedural testing for all patients. However, other societies recommended against and considered enough to maintain strict infection control strategies. Our aim was to evaluate this approach in order to see if it was safe for both patients and healthcare workers to proceed with the endoscopies without performing a systematic PCR on all patients. Retrospective chart review of all patients undergoing endoscopy without preprocedural COVID testing at our center from March 2020 to May 2021. PCR tests performed in the patients receiving an endoscopic procedure were analyzed, and patients who tested positive between 14 days before and after the endoscopic procedure were selected. The registry of the endoscopy unit members participating in these procedures was also analyzed. A total of 10,132 procedures were performed in the unit with 26 patients infected with SARS-CoV-2. Nineteen of these procedures were performed in patients with unknown SARS-CoV-2 carrier status. In 23 (88.5%) cases, transmission occurred through social or familial contact, and in 3 (11.5%), transmission occurred in the hospital. Four health care workers became infected during this period and none of them were related to the endoscopic procedures performed in patients with COVID-19. SARS-CoV-2 positive testing in asymptomatic ambulatory patients is rare and the adequate use of individual protective measures emerges as the main way to control the spread of COVID-19 infection in endoscopy centers.
