title: [Electrogastrography in children with functional abdominal pain and gastritis].
abstract: Electrogastrography (EGG) is non-invasive method for diagnosis of gastric electrical activity.
  
  
  OBJECTIVE
  We analysed gastric activity in children with chronic abdominal pain and functional disorders of alimentary tract or gastritis.
  
  
  METHODS
  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.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  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.
