An unrecognized threat: An evaluation of exposure to air pollutants during smoke-generating endoscopy procedures.

Abstract

Introduction: To characterize the smoke generated during several endoscopic procedures and evaluate the efficacy of a smoke evacuation system as a preventative measure.

Methods: Monitoring devices in closure proximity to patients measured particulate matter (PM) and volatile organic compounds (VOCs) during endoscopic procedures. The impact of a smoke evacuator system was also assessed.

Results: PM and VOC levels were significantly elevated during all procedures. The smoke evacuator reduced exposure.

Discussion: Smoke produced during endoscopy is a potential health risk for endoscopy staff. Protective measures and further research on long-term exposure effects are warranted.
