Clinical Failure After POEM, Aerosol Production During Endoscopy and Reporting AEs

In this issue of “Endoscopy Insights,” I highlight a new system for predicting clinical failures after peroral endoscopic myotomy, review a study on aerosol production during upper and lower GI endoscopies, and discuss the use of a new standardized scale for reporting adverse events during endoscopy.

POEM is performed on patients who have achalasia or esophageal disorders such as a diffuse
