Abstract:
Objective To explore the relationship between H.pylori (HP) infection and the functional dyspepsia (FD) by 4-lead electrogastrography (EGG). Methods The data of the gastric electrical activity of 163 children with FD, includ-ing 103 children with HP infection (group A), 60 without HP infection (group B) and 22 healthy controls (group C) were mea-sured by 4-lead EGG, which included normal slow wave percentage (N%), bradygastria percentage (B%), tachygastria per-centage (T%) and motilin uneven rhythm percentage (A%). EGG frequency and power examination included the main fre-quency (DF), the main power (DP) and postprandial/pre-prandial gastric electrical main power ratio (P/R). EGG data was compared between three groups. Results There was significant difference in pre-prandial and postprandial percentage of different slow wave frequency between group A and group B. There were no significant differences in pre-prandial and post-prandial changes of DF and DP between group A and group B. There was no significant difference in the pre-prandial and postprandial percentage change of different slow wave frequencies in 84 HP negative patients. But the significant change was found in pre-prandial and postprandial change of DF, DP and P/R. Conclusion The eradication of HP improved the gas-tric electrical activity and relieved the postprandial symptom in children with functional dyspepsia under HP infection.
