BACKGROUND: 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 postprocedure. 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. METHODS: Patients who underwent a redo POEM from 15 centers in 9 countries were included in a dedicated registry. Technical success was defined as successful completion of a second myotomy. Clinical success was defined as an Eckardt score of less than or equal to 3 after the second myotomy. Adverse events including anesthesia-related, operative, and postoperative adverse events were recorded. RESULTS: A total of 46 patients were included in the study. Average age was 49.3 years ± 16.78. 20 (45%) patients were male. The mean pre redo-POEM Eckardt score was 4.3 ± 2.48. Technical success was achieved in 46 (100%) patients. Clinical success was achieved in 41 patients (85%). The average post-POEM Eckardt score was 1.64 ± 1.67, with a significant difference of 2.58 (p<0.00001). 8 patients (17%) had adverse events consisting of procedural bleeding, all managed endoscopically. There were no deaths. No POEMs were aborted or required surgical conversion or assistance. DISCUSSION: For patients with persistent symptoms after POEM, repeat POEM appears to be an efficacious and safe technique. Further randomized trial comparing redo POEM versus Heller should be considered. Copyright © 2016 American Society for Gastrointestinal Endoscopy. Published by Elsevier Inc. All rights reserved.
