Coronavirus disease 2019 (COVID-19) is an acute respiratory disease that has rapidly spread to become a global pandemic. Bronchoscopy is clearly a high-risk manoeuvrer, so to continue endoscopic activity safely it was necessary to make many changes. We created different ways to access and exit the endoscopy theatre and reinforced our dressing/undressing regimens as well as equipment cleaning techniques. To prevent aerosol dispersion we used a bag valve mask with an antibacterial-antiviral filter, introducing the flexible bronchoscope orally rather than through the nose. For procedures with increased contagious risk a nasopharyngeal swab was required. From the date of the first case of COVID-19 in our hospital to December 31 2020, we performed 1027 bronchoscopies, in both negative and positive patients. No outbreaks occurred within the staff and no patients are known to have developed COVID-19 after a procedure. Our experience underscores how it is possible to continue endoscopic activity safely.
