通过气囊传感法观察了贲门失弛缓症及正常人各１０例的食管上、下括约肌及食管体部的运动功能，结果发现贲门失弛缓症食管下括约肌压力明显升高，食管下括约肌松弛率明显降低，食管下括约肌松弛时间明显缩短，食管体部出现病理性收缩波，食管上括约肌功能大致正常。提示贲门失弛缓症存在明显的食管运动功能异常。
Through the airbag sensing method to observe the achalasia of the cardia and the normal esophageal upper and lower sphincter and esophageal motility in 10 cases, the results showed that achalasia was significantly lower esophageal sphincter pressure, lower esophageal sphincter relaxation rate Significantly lower esophageal sphincter relaxation time was significantly shortened, the esophageal body pathological contraction wave, the function of the upper esophageal sphincter is generally normal. Suggest cardia achalasia there is significant dysfunction of esophageal motility.
