目的：研究胃电图（EGG）测量的电活动与胃窦十二指肠测压（ADM）测量的胃收缩活动之间是否存在相关性。我们还研究了潜在的运动障碍是否可以预测EGG parameters.METHODS：我们比较了21个参数测量从EGG测量的8个参数从ADM。EGG的能力，以确定潜在的诊断进行了测试，通过比较每个诊断组的EGG参数对其他患者。该研究包括148名患者和125名女性的记录。他们的中位年龄为45岁（范围17-76）years.RESULTS：我们发现EGG和ADM之间的相关性很弱，特别是反映对膳食反应的参数之间的相关性很差（r =-0.07，P = 0.39）。胃电图对潜在运动障碍的鉴别力也很低。慢传输型便秘（STC）患者在正常胃肠道中的餐后功率较低，（3.7 ± 0.5 vs 4.0 ± 0.5）和胃动力过速（3.5 +/- 0.4 vs 3.7 +/- 0.4）区域，胃功能正常的时间百分比较低[87.2（56.5-100）% vs 95.7（0-100）%]，胃速[9.3（0-33）% vs 3.5（0-100）%]和胃徐缓[1.8（0-20）% vs 0（0-17.1）%]的时间百分比较高。肠易激综合征患者胃功能正常的时间百分比较高，（96.5（62.5-100）% vs 93.3（0-100）%]和通过不稳定系数测量的较不稳定的主频[15（3-77）vs 24（2-72）]。EGG和ADM似乎测量胃运动活动的不同方面，但不能显示空间相关性。EGG对STC的诊断价值不高，但对STC的鉴别诊断有一定价值。(c)2007年WJG。All rights reserved.
AIM: To investigate if there is a correlation between electrical activity measured by electrogastrography (EGG) and contractile activity of the stomach as measured by antroduodenal manometry (ADM). We also studied whether the underlying motility disorder could be predicted from EGG parameters.METHODS: We compared 21 parameters measured from EGG with 8 parameters measured from ADM. The ability of EGG to identify the underlying diagnosis was tested by comparing EGG parameters for each diagnosis group against other patients. The study comprised recordings from 148 patients and 125 females. Their median age was 45 (range 17-76) years.RESULTS: We found few and weak correlations between EGG and ADM. Specifically the correlation between parameters reflecting the response to meal was poor (r = -0.07, P = 0.39). The discriminatory power of EGG for underlying motility disorder was also low. Patients with slow transit constipation (STC) showed a lower postprandial power in normogastric (3.7 +/- 0.5 vs 4.0 +/- 0.5) and tachygastric (3.5 +/- 0.4 vs 3.7 +/- 0.4) regions, a lower percentage of time with normogastria [87.2 (56.5-100)% vs 95.7 (0-100)%], and a higher percentage of time with tachygastria [9.3 (0-33)% vs 3.5 (0-100)%] and bradygastria [1.8 (0-20)% vs 0 (0-17.1)%]. Patients with irritable bowel syndrome had a higher percentage of time with normogastria (96.5 (62.5-100)% vs 93.3 (0-100)%] and a less unstable dominant frequency as measured by the instability coefficient [15 (3-77) vs 24 (2-72)].CONCLUSION: EGG and ADM seem to measure different aspects of gastric motor activity but cannotshow a spatial correlation. The diagnostic value of EGG is poor, but EGG may have some value for the identification of patients with STC. (c) 2007 WJG. All rights reserved.
