Summary

This study looked at whether wearing a special facemask during upper endoscopy (a procedure to examine the stomach and esophagus) can reduce the spread of tiny particles into the air. The goal was to better understand infection risks, like COVID-19, for healthcare workers. Researchers measured particle levels in 57 patients, with half using a facemask and half without.
