胃食管返流症(GORD)行内窥镜检时50%无阳性发现,其中1/5借食管可走动pH监测可发现酸返流增多。在有明显消化不良症状的病人,约40%不能查见异常。症状指数是酸返流时出现的症状数,除以可走动pH监测过程出现症状总数所得数值,它可作为诊断GORD的一项指标。有人认为指数为50%时可作此诊断,另有人以25%作为诊断GORD的依据。本文目的是在经内窥镜检或可走动pH监测证实为GORD的病人中,验证指数为25%或50%的诊断价值,并以此与两项检查均正常的病人进行比较。
Gastroesophageal reflux disease (GORD) endoscopy 50% no positive findings, of which 1/5 of the esophageal mobile pH monitoring can be found acid reflux increased. In patients with obvious symptoms of indigestion, about 40% can not see abnormalities. The symptom index is the number of symptoms that occur when acid reflux occurs, divided by the total number of symptoms that can appear during ambulatory pH monitoring and can be used as an indicator of GORD diagnosis. Some people think that when the index is 50% for this diagnosis, while others use 25% as a basis for the diagnosis of GORD. The aim of this paper is to verify the diagnostic value of 25% or 50% of the patients who have endoscopically or ambulatory g-pH-confirmed GORD and compare them to both patients with normal exams.
