Electrogastrography (EGG) is non-invasive method for diagnosis of gastric electrical activity.
We analysed gastric activity in children with chronic abdominal pain and functional disorders of alimentary tract or gastritis.
Skin EGG with 30-minutes recordings in preprandial period and after standard meal were done in 155 children, mean age 11,6 +/- 3,6 years. We analyzed data in groups: 1-functional abdominal pain (FAP), 2-gastritis, Helicobacter pylori negative, 3-gastritis, Helicobacter pylori positive, 4-controls.
EGG was in normal range in 32% of patients with FAP and in 27% of patients with gastritis. Abnormalities in gastric rhythm were noticed in highest percent in gr. 2 in fasting state. Normogastry was dominant in postprandial period in all groups. Statistical differences of some parameters of EGG (dominant frequency, dominant power) were found among study groups. We found higher percent of bradygastry in fasting state compared with postprandial period.
We conclude that different abnormalities in gastric myoelectrical activity could exist in chronic abdominal pain; dominant preprandial rhythm is mainly affected. We couldn't find typical changes in electrogastrogram for differentiate FAP and gastritis.
胃电图（EGG）是诊断胃电活动的非侵入性方法。
我们分析了患有慢性腹痛、消化道功能障碍或胃炎的儿童的胃活动情况。
对155名平均年龄为11.6±3.6岁的儿童进行了餐前和标准餐后30分钟的皮肤EGG记录。我们将数据分为以下几组进行分析：1. 功能性腹痛（FAP）组；2. 幽门螺杆菌阴性胃炎组；3. 幽门螺杆菌阳性胃炎组；4. 对照组。
FAP患者中32%以及胃炎患者中27%的EGG处于正常范围。空腹状态下，第2组胃节律异常的比例最高。所有组餐后均以正常胃电活动为主。研究组之间在EGG的一些参数（主频、主功率）上存在统计学差异。我们发现空腹状态下胃动过缓的比例高于餐后。
我们得出结论，慢性腹痛患者可能存在不同的胃肌电活动异常；餐前的主导节律主要受到影响。我们未发现用于区分FAP和胃炎的典型胃电图变化。
