  Purpose
Achalasia is a rare esophageal motility disorder, characterized by incomplete lower esophageal sphincter relaxation, increased Lower esophageal sphincter (LES) tone, and aperistalsis of the esophagus. Typical clinical symptoms are dysphagia,regurgitation and chest pain. Traditional treatments include endoscopic balloon dilatation or botulinum toxin injection, laparoscopic Heller myotomy with or without a partial fundoplication. Peroral endoscopic myotomy (POEM) has been developed as a further endoscopic effective and minimal invasive treatment. The aim of this study is to investigate the efficacy and safety of POEM in our department, and to assess short-term and long-term efficacy of POEM by using Stooler score, Echardt score, esophageal barium and manometry.

Estimated Study Completion Date: December 2013
Estimated Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Intervention Details:
    Procedure: peroral endoscopic myotomy
    A 3-cm incision is made into the mucosa after injection of saline and methylene blue. A submucosal tunnel is created from the mid-esophagus to the gastric cardia by a triangle-tip knife. The circular muscle fibers or full-thickness muscle are divided by the triangle-tip knife over a length of 6-20 cm on the esophagus, starting 3 cm below the initial mucosal incision, and extended 3-4cm onto the gastric cardia. The mucosal entry site is closed using standard endoscopic clips at last.
