Various studies have suggested that the most effective treatment of esophageal achalasia is surgical therapy. The basic concept of this surgical therapy has not changed since Heller proposed esophageal myotomy for the purpose of resolution of lower esophageal obstruction for the first time in 1913,but the most common approach has changed from openchest surgery to laparoscopic surgery. Currently,the laparoscopic surgery has been the procedure of choice for the treatment of esophageal achalasia. During the process of the transition from open-chest surgery to laparotomy,to thoracoscopic surgery,and to laparoscopic surgery,the necessity of combining antireflux surgery has been recognized. There is some debate as to which type of antireflux surgery should be selected. The Toupet fundoplication may be the most effective in prevention of postoperative antireflux,but many medical institutions have selected the Dor fundoplication which covers the mucosal surface exposed by myotomy. Recently,a new endoscopic approach,peroral endoscopic myotomy(POEM),has received attention. Future studies should examine the long-term outcomes and whether POEM becomes the gold standard for the treatment of esophageal achalasia.展开更多
