Impact of prior treatment on long-term outcome of peroral endoscopic myotomy in pediatric achalasia

Retrospective study of 17 pediatric achalasia patients demonstrates 88.2% long-term clinical success with POEM at median 55-month follow-up. Prior treatment with pneumatic dilatation or Heller myotomy did not negatively impact POEM outcomes, supporting its use as both primary and salvage therapy in children.
