Per-oral Endoscopic Myotomy

  • Chapter

Part of the book series: Clinical Gastroenterology ((CG))

Abstract

Per-oral endoscopic myotomy, or POEM, has emerged as the most innovative therapy in achalasia after its introduction in 2008 and the most successful application of NOTES to date. Moreover, it is the prototype for the burgeoning field of tunnel endoscopy. It represents the endoscopic equivalent of laparoscopic Heller myotomy (LHM). POEM has been well validated in terms of impressive efficacy and notable safety and is being now performed all over the world by both surgeons and gastroenterologists. We will describe POEM development, patient evaluation, technique, postprocedural care, complications, accumulating longer-term data, comparison with other achalasia therapy, training concerns, and perspectives for the future.
