目的：探讨食管压力测定在评估气囊扩张术治疗贲门失弛缓症疗效中的作用。
Aims: To appraise the role of esophageal manometry in assessment of pneumatic dilatation therapy on achalasia.
方法：对2 0例贲门失弛缓症患者行球囊扩张术。
Methods:Twenty patients with achalasia of cardia were given ballon dilation.
食管贲门失弛缓症的为需要的是非常罕见，即使在一食道扩张的存在，并应预留失败后切开术。
The need for esophagectomy for achalasia is very uncommon, even in the presence of a dilated esophagus, and should be reserved for failures after myotomy.
结论：内镜下气囊扩张术治疗贲门失弛缓症具有良好的中远期疗效，值得推广应用。
Conclusions: Endoscopic balloon-dilating therapy for achalasia had good medium-long-term curative effect and deserved for further application.
目的：观察内镜下气囊扩张术治疗贲门失弛缓症的中远期疗效，探索贲门失弛缓症的非手术治疗方法。
Objective:To observe the medium-long-term curative effect of endoscopic balloon-dilating therapy for achalasia. To explore a kind of non-surgical method for achalasia.
食管与贲门失弛缓症是一个显着扩张或和乙状结肠形食管患者的标准治疗方法，认为在这种情况下Heller术无效。
Esophagectomy was the standard treatment in patients with achalasia and a markedly dilated or sigmoid-shaped esophagus, with Heller myotomy considered to be ineffective in such cases.
