Open peroral endoscopic myotomy for achalasia with failed Heller myotomy

Abstract

In May 2017, a 55-year-old man was referred to our endoscopy center because of dysphagia and chest pain. The patient with a history of failed Heller myotomy was diagnosed as a recurrence of achalasia (type II) with an Eckardt score of 13. Selective myotomy was achieved by peroral endoscopic myotomy without a submucosal tunnel for this case. We describe this technique as open peroral endoscopic myotomy(O-POEM) (Fig 1, 2).
