Abstract
Blown-out myotomy (BOM) is a potential postoperative complication for achalasia patients after both surgical and peroral endoscopic myotomy (POEM). It causes diverticular-like changes and food retention in the lower esophagus due to residual contraction and impaired discharge of esophageal contents. It occurs in 17.8% of patients after POEM and can be symptomatic [1]; however, no effective treatment for patients with symptomatic BOM has been reported.
