Twenty four hour esophageal pH monitoring was performed in 110 patients, placing a pH electrode 5 cm above the proximal border of the lower esophageal sphincter. This test allows to measure the total lapse in which there is an acid pH in the esophagus, the ability of the esophagus to get rid of the acid reflux and documents the relationship between esophageal pH and symptoms. Upper GI endoscopy showed a normal esophagus in 38 patients, and esophagitis grade I in 25, grade II in 11, grade III in 25 and grade IV in 11. There was a high correlation between the severity of esophagitis and the total time in which the esophagus was exposed to an acid pH. It is concluded that this test can be used as a "gold standard" for gastroesophageal reflux detection.
对110例患者进行了24小时食管pH监测，将pH电极放置在食管下括约肌近端边界上方5厘米处。该测试能够测量食管中存在酸性pH值的总时长、食管清除酸反流的能力，并记录食管pH值与症状之间的关系。上消化道内镜检查显示，38例患者食管正常，25例为I级食管炎，11例为II级，25例为III级，11例为IV级。食管炎的严重程度与食管暴露于酸性pH值的总时长之间存在高度相关性。得出的结论是，该测试可作为胃食管反流检测的“金标准”。
