The use of personal protective equipment in endoscopy: what should the endoscopist wear during a pandemic?

Endoscopists are at high risk of exposure and nosocomial transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 virus) when performing endoscopic procedures due to the highly aerosol generating nature of these procedures. At present, there is still no consensus among endoscopists with regards to the type of protective equipment to be worn by healthcare workers, when performing endoscopy during the coronavirus 2019 (COVID-19) pandemic. This review encompasses a summary of currently published guidelines related to the use of personal protective equipment (PPE) when performing endoscopic procedures during the COVID-19 pandemic. With increasing calls to rationalize the use of PPE due to shortages in global supply chains, the review offers a concise summary on the most appropriate and adequate use of PPE when performing endoscopy during the pandemic. It is expected that these adaptations in the use of PPE during the pandemic will help to improve standards of care and safety of healthcare workers.
