摘要
目的：作者应用体表胃电图研究门脉高压患者胃动力障碍发生率及其与肝功能的关系。方法：ＷＣＤＦ型胃肠电分析仪观察３０名肝硬化门脉高压患者和１５名健康人空腹胃肌电活动情况，观察指标包括平均振幅（ＡＰ）、平均过零频率（Ｆ２）、中心频率（Ｆｃ）、主频（Ｆｐ）以及频谱形态。结果：门脉高压组患者胃电节律紊乱率明显高于健康组，其中Ｆ２分别为３７％和５０％；Ｆｐ分别为５７％和４７％；ＣｈｉｌｄＡ组胃窦电节律紊乱率在Ｆｐ、Ｆ２分别为３６％、１８％；ＣｈｉｌｄＢ分别为６０％、３３％；而ＣｈｉｌｄＣ组则１００％有胃窦电节律异常。结论：本研究提示门脉高压患者胃电节律紊乱发生率较正常人明显升高，肝功能对胃电节律有影响。
Aims:to study gastric dysmotility of cirrhotic patients using cutaneous EGG.Methods:Fasting gastric electrical activity was recorded and measured in 30 cases of cirrhotics with portal hypertension and compared with that in healthy indiveduals using EGG.Measurements included:mean amplitude(AP),mean hyper zero frequency (PZ),central frequency(FZ),dominant frequency(FP) and spectral pottern.Results:the percentage of gastric electrial disturbances was much higher in cirrhotics than that of normals.The valuse of FZ were 37% and 50%,that of FP were 57% and 47%.In accord with Childs classifications,the respective percentage of gastric electrical disturbance recorded form gastric antrum in Child A were 36% and 18%,in Child B were 60% and 33%,all Child C patients had this abnormality,Conclusions:the present study suggested percentage of gastric electrical disturbance was much higher in cirrhotics than that of normals.Gastric electrical disturbances were also related to liver dysfunction as illustrated in this study.
