早在1969年,就有人提出用18小时食管末端pH测定了解胃、食管反流情况,对于鉴别病理性和生理性反流具有很大价值。目前用pH敏感的放射性遥测技术和灵敏的接受系统,可对测试者作24小时食管pH监测。作者对20名经组织学证实、有症状的反流性食管炎患者和20名正常人作了食
As early as 1969, it was suggested that using the 18-h distal esophageal pH measurement to understand gastric and esophageal reflux was of great value in identifying pathological and physiological reflux. Current pH-sensitive radiological telemetry and a sensitive receiver system allow 24-hour esophageal pH monitoring. The authors ate 20 patients with symptomatic reflux symptomatic esophagitis and 20 normal controls
