The conservative treatment of achalasia of the esophagus with balloon or mechanical dilators may be difficult, or even impossible, it the esophagus in an advanced illness is so tortuous (sigmoid esophagus) that the dilator cannot be placed in the cardia. An endoscope dilator with the aid of which dilation is readily possible even in such cases, has been developed by various individuals. Our own experience and the results obtained in 11 patients with esophageal achalasia treated with the endoscope dilator, are presented. The particular advantages of this method of treatment are simple, low-risk placement of the balloon in the cardia before and during dilation, and the possibility of inspecting the cardia for complications immediately after dilation.
对于患有贲门失弛缓症的患者，若采用球囊或机械扩张器进行保守治疗，可能会有困难，甚至无法实施，因为病情严重时食管会极度扭曲（乙状结肠样食管），导致扩张器无法置入贲门。针对这种情况，不同的人研发出了一种内镜扩张器，即便在此类病例中也能轻松实现扩张。本文介绍了我们使用内镜扩张器治疗11例食管贲门失弛缓症患者的自身经验及所取得的结果。这种治疗方法的独特优势在于，在扩张前及扩张过程中，能简便且低风险地将球囊置入贲门，并且在扩张后可立即检查贲门是否出现并发症。
