Peroral endoscopicmyotomy versus pneumatic dilation - result from a retrospective study with 1-year follow-up

摘要

Background and aims On the basis of lesser rates of major adverse events and a short-term efficacy as Heller's myotomy, there is a growing enthusiasm in favor of peroral endoscopic myotomy (POEM), whereas study comparing POEM and pneumatic dilatation (PD) is quite rare. The aim of this study was to evaluate the efficacy of POEM and PD in Chinese achalasia patients in a retrospectively designed study.
