Peroral endoscopic myotomy in treatment-naive achalasia patients versus prior treatment failure cases

摘要

Background and study aim Peroral endoscopic myotomy (POEM) has emerged as an effective treatment modality for achalasia. Prior treatment may affect the outcomes of subsequent management. In this study, we aimed to compare the safety and efficacy of POEM in treatment-naive patients vs. those with prior treatment failure (PTF).
