摘要
以ＳＰＥＣＴ胃排空检测技术和ＷＣＤＦ－４Ｂ胃电分析仪检测了１２例ＦＤ患者液、固体食物胃排空和体表胃电图的变化。结果显示：ＦＤ患者的液体胃排空与对照组无明显差异，仅在摄食后比对照组更多地分布于远端胃内；固体食物的排空模式发生变化，表现为初始排空较快，继后的排空延缓，７例半排空时间延长。除胃电节律紊乱率高于对照组外，无论空腹或餐后ＰＤ组的胃电基本参数均与对照组无显著差异。结果说明ＦＤ患者以固体食物胃排空延迟为主，这种改变不能解释ＦＤ的发生，体表胃电图不能预测胃排空的变化。
astric emptying patterns for both solid and liquid meals and cutaneous electroga-atrogram(EGG)were investigated in 12 patients with functional dyspepsia(FD)and12 healthy volunteers by means of SPECT and WCDF一4B electrogastrography. The re-sults showed that for liquid meal the emptying patterns and half emptying time(T_50)were not significantly different between the two groups.In contrast,the patients hadohanged emptying patterns for solid food with a rapid initial phase and then a slowphase,which is just contrary to that in controls.Seven cases showed delayed T_50.However,there were not significant differences in intragastric distribution between pati-ents with and without delayed T_50,and between patient group and controls.The basicparameters of EGG(such as frequency and amplitude of potential)showed no signifi-cant difference between the two groups except that in FD group the arrhythemia rateswere higher than in controls either fasting or postprandially. These findings indicatedthat the patient group shows mainly delayed emptying of solid meal,but not beingattributed to their symptoms and that the abnormality of cutaneous EEG is not a pre-dictor of changed gastric emptying patterns.
