食管测压在贲门失弛缓症的应用

目的：研究贲门失弛缓症的食管压力改变及经腹改良Heller手术的疗效。方法：应用SGY－3多功能消化道检测仪对9例贲门失弛缓症术前及其中的7例术后进行食管压力测定，同时与8例健康人对照。结果：贲门失弛症患者的食管体部静息压和下括约肌静息压分别为8．72mmHg和48．17mmHg，显著高于健康人的1．18mmHg和17．52mmHg，贲门失弛缓症患者手术前后食管体部均无原发性蠕动。结论：经腹改良Heller手术能有效缓解贲门失弛缓症的吞咽困难，但不能恢复食管的蠕动功能。

The manometric study of esophagus in achalasia

Objective To evaluate the manometric feature of achalasia and the result of improved Heller's operation through abdominal incision. Methods The esophageal pressure of 9 pre operational cases and 7 post operational cases in the same group of achalasia were tested by SGY 3 digestive tract motility measuring instrument.Eight healthy people were chosed as controls.Results The esophageal body pressure and lower esophageal sphincter pressure of the patients with achalasis were 8.72 mmHg and 48.17mmHg respectively, that was higher significantly than the 1.18 mmHg and 17.52 mmHg of healthy people. The esophageal body had not primary peristalsis in both pre and post-operational patients of achalasia.Conclusion The improved Heller's operation can relief the dysphagia of achalasia, but it can not recover the peristaltic function of esophagus.
