Abnormalities of gastrointestinal motility and transit time have been reported in association with end-stage liver disease. Motility abnormalities could be routinely studied if a simple noninvasive test were available. The electrogastrogram is a cutaneous measure of gastric myoelectric activity and correlates well with serosal recordings of gastric myoelectric activity. The aim of this study was to evaluate gastric myoelectric activity in patients with end-stage liver disease.
Fourteen patients with end-stage liver disease had gastric myoelectric activity measured with the electrogastrogram. An electrogastrogram was considered abnormal when normal gastric slow waves were seen less than 70% of the time or there was no increase in the electrogastrogram amplitude after a meal.
Abnormal electrogastrograms were present in 8 of 14 (57%) end-stage liver disease patients.
Abnormal gastric myoelectric activity is common in end-stage liver disease.
已有报道称终末期肝病与胃肠动力及转运时间异常有关。如果有简单的非侵入性检测方法，动力异常就可以常规进行研究。胃电图是一种测量胃肌电活动的皮肤检测方法，与胃肌电活动的浆膜记录相关性良好。本研究的目的是评估终末期肝病患者的胃肌电活动。
14例终末期肝病患者通过胃电图测量胃肌电活动。当正常胃慢波出现时间少于70%或餐后胃电图振幅无增加时，胃电图被认为异常。
14例终末期肝病患者中有8例（57%）胃电图异常。
胃肌电活动异常在终末期肝病中很常见。
