目的:分析描述胃间质瘤(GIST)患者的胃电活动特点,探讨GIST对胃电活动的影响.方法:运用多导胃电图检测27例胃GIST患者(GIST组)及30例健康志愿者(对照组)的餐前餐后胃电参数,并进行对比分析.结果:对照组餐后各导联较餐前均出现平均频率(MF)、平均幅值(MA)及正常慢波百分比(N%)增高,过缓频率百分比(B%)较餐前减低,差异有统计学意义(P < 0.05或P < 0.01), GIST组未出现相应的胃电图改变(P > 0.05);GIST组各导联餐前MF、MA高于对照组,N%餐前1、3、4导及餐后各导联均低于对照组,过速频率百分比(T%)各导联餐前餐后均高于对照组,差异有统计学意义(P < 0.01);GIST组与对照组患者胃动过速发生率分别为66.7%,3.3%,GIST组节律正常患者所占百分比低于对照组,差异有统计学意义(P < 0.01).结论:GIST患者存在餐前餐后胃电活动异常,异常胃电节律以胃动过速为主.

Objects: To investigate the behavior of gastric electrical activity in patients with gastrointestinal stromal tumor(GIST) to identify the influences of GIST on the normal gastric electrical activity. Methods: The electrogastrogram (EGG) parameters of 27 patients with gastric GIST (GIST group) and 30 healthy volunteers (control group) were detected by the multi-channel electrogastrogram and the data were analyzed. Results: The values of postprandial mean frequency (MF), mean amplitude (MA) and the percentage of normal slow wave (N%) were increased, and the percentage of bradygastria (B%) was decreased than those of the fasting in control group(P < 0.05 or P < 0.01). However, those postprandial parameter changes were not found in GIST group(P > 0.05). Compared with control group, the fasting MF and MA increased, the fasting N% of lead 1, 3, 4 and postprandial N% decreased, both percentages of fasting and postprandial tachygastria (T%) increased in GIST group (P < 0.01). The tachygastria incidence was significantly higher in GIST group than that of control (66.7% vs 3.3%, P <0.05). Conclusion: The gastric electrical activity was affected by the existence of GIST. The abnormal gastric electrical rhythm displayed mainly as tachygastria.
