摘要
Peroral endoscopic myotomy(POEM) is a new endoscopic treatment for achalasia. Compared to the classical surgical myotomy, POEM brings at least the advantage of minimal invasiveness. The data provided until now suggest that POEM offers excellent short-term symptom resolution, with improvement of dysphagia in more than90% of treated patients, with encouraging manometric outcomes and low incidence of postprocedural gastroesophageal reflux. The effectiveness of this novel therapy requires long-term follow-up and comparative studies with other treatment modalities for achalasia. This technique requires experts in interventional endoscopy, with a learning curve requiring more than 20 cases, including training on animal and cadaver models, and with a need for structured proctoring during the first cases. This review aims to summarize the data on the technique, outcomes, safety and learning curve of this new endoscopic treatment of achalasia.
