A prospective analysis of GERD after POEM on anterior myotomy

Abstract

POEM is effective and safe in treating achalasia, with no occurrence of clinically significant refractory GERD. Myotomy during POEM, especially of the gastric side, was not associated with ≥grade B (requiring medical intervention) reflux esophagitis. Extended gastric myotomy (2-3 cm) during POEM is recommended to improve outcomes.
