用24小时食管pH监测法诊断食管原性胸痛

24-Hour esophageal pH monitoring ror suspectedesopbageal originated chest pain

应用２４小时食管ｐＨ监测法检查３０例排除了食管形态学改变的胸痛患者，发现其中２６例（８６．７％）ｐＨ值异常，存在异常胃食管反流。ｐＨ值昼夜异常者１６例（６１．６％），单纯白天异常者８例（３０．８％），单纯夜间异常者２例（７．７％）。胸痛与酸暴露相关者１８例（６０％）。食管ｐＨ监测是诊断胃食管反流所致之食管原性胸痛的有效方法。该法对酸暴露、食管酸清除能力与胸痛关系的分析以及食管原性胸痛与心原性胸痛的鉴别具有重要作用。

AbstractThirty patients with suspected esophageal origi-nated chest pain were studied by 24h esophageal pHmornitoring. All of them complained of chest pain,heart burn,acid reflux or dysphagia.The resultshowed abnormal pH in 26 patients(86.7%).Sixteenof them had pH abnormalities in both day and night,whereas 8 had only abnormal day pH,and 2 pH out ofthe normal limits at night.Chest pain episode was cor-related with the abnormalities in 18 cases(60%). Four patients with coronary heart disease showed si-multaneous gastro-esophageal reflux originated chestpain;the positive correlation was obtained.Their di-agnosis of cardiac chest pain was doubtful.We suggest-ed that 24h pH mornitoring was a significant method todetermine the cause of chest pain.
