Aerosol and droplet generation in upper and lower GI endoscopy: whole procedure and event-based analysis.

ABSTRACT:

Background and aims

Aerosol-generating procedures have become an important healthcare issue during the coronavirus disease 2019 (COVID-19) pandemic because the severe acute respiratory syndrome coronavirus 2 virus can be transmitted through aerosols. We aimed to characterize aerosol and droplet generation in GI endoscopy, where there is little evidence.

Methods

This prospective observational study included 36 patients undergoing routine peroral gastroscopy (POG), 11 undergoing transnasal endoscopy (TNE), and 48 undergoing lower GI (LGI) endoscopy. Particle counters took measurements near the appropriate orifice (2 models were used with diameter ranges of .3-25 μm and 20-3000 μm). Quantitative analysis was performed by recording specific events and subtracting background part
