摘要
目的比较不透X线标志物法(ROMs)和C-辛酸呼气试验法(OBT)检测胃固体排空方法的相关性。方法对32例胆汁反流性胃炎(BRG)组和27例对照组(HC)同时应用13C-辛酸呼气试验及不透X线标志物法进行胃排空检测,将所测参数输入计算机,用专用软件分析。结果不透X线标志物法与13C-辛酸呼气试验法测定的胃排空结果具有很好的相关性(P<0.001),两种检测方法均显示BRG组的固体胃排空较HC组明显延迟(P<0.05)。结论不透X线标志物法是一种非侵入性检测胃固体排空的方法,操作简单,与13C-辛酸呼气试验法比较,具有较好的敏感性、特异性及准确性。BRG患者有明显的胃排空延迟,这可能是其发生病理性胆汁反流的一个重要原因。
Objective To compare two measurements of gastric emptying rate of solids ： Radio-opaque markers （ROMs） and ^13C-octanoic acid breath test （OBT）. Methods Gastric emptying rate of solids had been measured with both Radio-opaque markers （ ROMs ） and ^13 C-octanoic acid breath test （OBT） for 32 cases with bile reflux gastritis （BRG） and 27 healthy control. All parameters were input computers and analyzed with specialized analytical software. Results ROMs and OBT showed good correlations in measurements of gastric emptying rate of solids （P 〈 0. 001 ）. Both measurements identified significant delay in gastric emptying of solids for BRG patients,comparing with healthy controls （ P 〈 0.05 ）.Conclusions ROMs is a non-invasive,easy-to-operate,cost effective and reliable measurement of gastric emptying rate of solids. Comparing with OBT ,it shows better sensitivity ,variability and accuracy. BRG patients show significant delay of gastric emptying, which might be an important reason for their pathological bile reflux.
