The Upper Esophageal Sphincter is Not Round: A Pilot Study Evaluating a Novel, Physiology-Based Approach to Upper Esophageal Sphincter Dilation

Abstract

Pilot data suggest that simultaneous dilation of the UES with two controlled radial expansion balloon dilators is feasible, safe, and effective. Future investigation is necessary to confirm the safety of this technique in a larger cohort and to use objective measures of efficacy to compare the technique to conventional dilation with a single dilator.
