Abstract:
Peroral endoscopic myotomy (POEM) has been developed as an incisionless, minimally invasive endoscopic treatment intending a permanent cure for esophageal achalasia. The concept of endoscopic myotomy was first reported about 3 decades ago, but the direct incision method through the mucosal layer was not considered to be a safe and reliable approach. A novel method of endoscopic myotomy was developed and established by the authors. In this article, the current techniques, applications, and clinical results of POEM are described.
