评价胃食管反流病调查评分量表(Gerd Q)对胃食管反流病(GERD)患者初步诊断中的应用价值。

采用随机抽样法选取收集自2015年6月～2016年6月，在新疆维吾尔自治区人民医院微创、疝与腹壁外科疑似GERD患者350例，应用Gerd Q评分量进行评分，并进行专科处理，进一步完善内镜、食管24 h PH检测和(或)质子泵抑制剂(proton pump inhibitor，PPI)诊断实验等进一步确诊，并与Gerd Q值进行比较，最后计算出诊断GERD的临界值进而分析Gerd Q量表在诊断GERD中的价值。

GERD患者中Gerd Q积分主要集中于7～14分，非GERD组主要集中于7分以下，差异有统计学意义(P<0.05)；Gerd Q诊断临界值升高后，其灵敏度逐渐降低，特异度逐渐升高，Gerd Q评分量表以8分为临界值时，ROC曲线下面积为0.802，其敏感性和特异性分别为77.50%和87.31%，Youden指数0.648，对GERD患者诊断的阳性符合率为77.72%，阴性符合率为87.8%。

Gerd Q量表是GERD的良好筛查工具之一，敏感性和特异性较高，可用于GERD的初步诊断。

To evaluate the application of Gerd Q in the diagnosis of gastroesophageal reflux disease(GERD)in patients with gastroesophageal reflux disease.

Patients were selected from June 2015 to June 2016 in People′s Hospital of Xinjiang Uygur Autonomous Region who was suspected as GERD and ask them to fill the Gerd Q. All patients received Gerd Q questionnaire survey, gastroscope, 24h pH monitoring of esophageal and/or proton pump inhibitor(PPI)treatment.gastroscope, 24h pH monitoring of esophageal and/or PPI treatment were regarded as golden diagnosis standards.The results were compared with Gerd Q scores, in order to calculate the diagnostic sensitivity, specificity and accuracy of Gerd Q.

Gerd Q scores were mainly concentrated in 7~14 points, and non GERD group mainly concentrated below 7 points, after the Gerd Q diagnostic threshold increases, the sensitivity decreases and the specificity increases, when the area under the ROC curve is 0.802 the best diagnostic sensitivity and specificity were 77.5% and 87.3% respectively when score 8 was set as the critical value for the Gerd Q, The Youden index reached a maximum of 0.648.The positive coincidence rate of diagnosis in patients with GERD was 77.72%, and the negative coincidence rate was 87.8%.

The Gerd Q is a good screening test for the diagnosis of GERD, the preliminary diagnosis rate is high, which can be used as a noninvasive, simple, easy, economical and effective method for the clinical diagnosis of GERD.
