A multicenter international registry of redo per-oral endoscopic myotomy (POEM) after failed POEM

摘要

Background and Aims: Per-oral endoscopic myotomy (POEM) has become an accepted treatment for patients with achalasia. Despite its excellent efficacy rate of greater than 80%, a small percentage of patients remain symptomatic after the procedure. Limited data exist as to the best management for recurrence of symptoms after POEM. We present the first international, multicenter experience on the efficacy and safety of a repeat POEM in the management of achalasia.
