Methods： Between Dec. 2008 and May 2014, 125 patients with typical GERD symptoms were subjected to 24-h MII-pH monitoring. Twelve patients with normal MII-pH profiles were not considered for analysis. The reflux parameters of 113 GERD patients with abnormal Mll-pH results were analyzed. Results： （1） DeMeester scores were above the normal range in 46.90% （53/113） of GERD patients. Weakly acidic refluxes were prevalent in GERD patients, and the frequency of abnormal weakly acidic reflux was 75.22% （85/113）. The frequencies of abnormal symptom index （SI） and symptom association probability （SAP） were 19.47% （22/113） and 14.16% （16/113）, respectively. （2） The frequencies of DeMeester scores, the %time at pH〈4, and the numbers of reflux episodes and of long reflux episodes 〉5 min were significantly higher in male patients than in female patients. （3） The %time at pH〈4 was much higher during upright periods than during supine periods. During supine periods, 31.86% （36/113） of GERD patients had delayed bolus clearance time, compared with 19.47% （22/113） during upright periods. （4） The number of abnormal DeMeester scores, %time at pH〈4, and the number of acid refluxes during upright periods were significantly higher in obese GERD patients than in GERD patients with a normal BMI. Over- weight GERD patients also had many more acid refluxes during upright periods than GERD patients with a normal BMI Conclusions： Weakly acidic refluxes were prevalent in Chinese GERD patients. The factors male, gender, upright position, obesity （BMI〉25）, but not age, may increase the frequency and severity of GER.展开更多
目的评价24 h多通道腔内阻抗-pH监测(24 h MII-pH)在胃食管反流病(GERD)诊断中的应用价值。方法选取2016年1月—2018年6月在某院就诊的326例GERD患者作为观察组,并选取同时期健康志愿者75例作为对照组,均行24 h MII-pH监测,并记录GERD...目的评价24 h多通道腔内阻抗-pH监测(24 h MII-pH)在胃食管反流病(GERD)诊断中的应用价值。方法选取2016年1月—2018年6月在某院就诊的326例GERD患者作为观察组,并选取同时期健康志愿者75例作为对照组,均行24 h MII-pH监测,并记录GERD相关参数。比较MII-pH监测与单独pH监测对GERD的诊断情况。结果①24 h pH监测结果显示,观察组各监测指标均显著高于对照组(P<0.05);②24 h MII-pH监测结果显示,除弱碱反流次数两组无明显差异(P>0.05)外,在其他指标比较中,观察组均显著高于对照组(P<0.05);③24 h MII-pH监测GERD的阳性诊断率为87.42%,与单纯食管pH监测的44.78%比较,差异有统计学意义(P<0.05)。结论24 h MII-pH可识别反流物的运动方向、酸碱性和成分,提高GERD的检出率,具有重要的临床价值。展开更多
