目的：探讨功能性消化不良（ＦＤ）患者胃电改变及西沙必利对胃电的影响。方法：对３８例ＦＤ患者进行空腹及服西沙必利后６０ｍｉｎ体表胃电图（ＥＧＧ）描记。结果：ＦＤ患者胃电节律紊乱发生在胃体部为４２．１１％，胃窦部为６３．１６％；服西沙必利后６０ｍｉｎ胃体电节律紊乱５０％好转，胃窦部５８．３３％消失。结论：胃动力障碍是ＦＤ的主要原因，胃动力药西沙必利能使胃电节律紊乱好转；对ＦＤ患者可提倡进行ＥＧＧ检查，以指导临床治疗。
Objective: To investigate the changes of gastric electrical activity in patients with functional dyspepsia (FD) and the effect of cisapride on gastric electrical activity. Methods: The gastric electrogastrography (EGG) was performed on 38 patients with FD at 60 min after fasting and taking cisapride. Results: The electrogastric dysrhythmias in FD patients were 42.11% in stomach and 63.16% in gastric antrum, and 50% in gastric electrical disturbance was improved in 60 minutes after cisapride. The gastric antrum was 58.33% disappear. Conclusions: Gastric motility disorder is the main reason of FD. Gastric drug drug cisapride can improve the disturbance of gastric electrical rhythm. EGG can be advocated in FD patients to guide the clinical treatment.
