Outcomes of per-oral endoscopic myotomy for treatment of esophageal achalasia with a median follow-up of 49 months

Per-oral endoscopic myotomy (POEM) has received wide acceptance as a highly effective and safe treatment for esophageal achalasia. Short-term and small-scale studies are ample but long-term large-scale studies are few. The aim of the study was to systematically analyze our long-term results of POEM, with particular emphasis on POEM failures and associated risk factors.
