Blown-out myotomy: emerging phenotype in post-myotomy failure after POEM and Heller myotomy.

Esophagus : official journal of the Japan Esophageal Society - 1 Jan 2026

Abstract excerpt

Blown-out myotomy (BOM) is an underrecognized but increasingly acknowledged long-term structural complication following both laparoscopic Heller myotomy (LHM) and peroral endoscopic myotomy (POEM) for achalasia. Characterized by a localized pseudo-diverticulum or eccentric dilation at the prior myotomy site, BOM often manifests with recurrent dysphagia, regurgitation, and food stasis, and may mimic treatment...
