Objective To compare two measurements of gastric emptying rate of solids: Radio-opaque markers ( ROMs) and 13 C-octanoic acid breath test ( OBT).
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。
Measurement of gastric emptying and gastrointestinal transit time with radio-opaque markers
不透X线标志物法胃排空及胃肠通过时间的测定
Objective To detect the delay of gastric emptying in bile reflux gastritis with radio-opaque markers.
目的采用不透X线标志物法（ROMs）检测胃固体排空功能，探讨胃固体排空障碍在胆汁反流性胃炎（Bilerefluxgastritis，BRG）中的存在和作用。
METHODS: Whole gastrointestinal transit time ( GTT), mouth-intestine transit time and colon transit time ( CTT) were determined with plain abdominal photograph at 12 hours, 24 hours and 48 hours after orally administrated of radio-opaque markers.
方法：通过口服不透X线标志物，用X线拍片法分别于12,24和48h摄腹部平片，测定28例功能性便秘患儿和68例正常儿童全胃肠传输时间、口-盲时间和结肠传输时间。
