摘要: 目的:探讨胃间质瘤(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(健康对照组)的餐前餐后胃电参数,并进行对比分析。结果:健康对照组餐后各导联较餐前均出现平均频率(MF)、平均振幅(MA)及正常慢波百分比(N%)的增高,差异有统计学意义(P<0.05), GIST组未出现相应的胃电图改变(P>0.05)2;GIST组各导联餐前MF高于对照组,N%餐前1、3、4导及餐后各导联均低于对照组, T%各导联餐前餐后均高于对照组,MA高于对照组,差异有统计学意义(P<0.05或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%,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。

Abstract: Objects: to explore whether GIST influences the gastric myoelectrical activity. Methods: the EGG parameters of 27 cases of gastric GIST patients (GIST group) and 30 healthy volunteers (control group) were detected by the multi-channel electrogastrogram and were analyzed. Results: Compare with the fasting, the control group postprandial mean frequence (MF), mean amplitude (MA), and normal slow wave percentage (N%) increased, P<0.05. However, those postprandial parameters changes were not found in GIST group, P>0.05. Compared with Control group, the fasting MF and fasting MA increased, the fasting N% of lead 1,3,4 and postprandial N% decreased, both fasting and postprandial T% increased in GIST group, P<0.05 or P<0.01; the tachygastria incidence of GIST group was significantly higher than the controls (66.7% vs 3.3%, P <0.05). Conclusions: The existence of GIST may affect both fasting and postprandial gastric myoelectrical activity. The abnormal gastric electrical rhythm mainly displayed as tachygastria.
