Summary

Children with unexplained upper gastrointestinal issues often have abnormal gastric electrical activity. Electrogastrography (EGG) can help diagnose these conditions, revealing irregularities in stomach rhythm and prolonged gastric emptying.

Area of Science:

  • Pediatric Gastroenterology
  • Neurogastroenterology
  • Medical Diagnostics

Background:

  • Recurrent upper intestinal dysfunction in children presents with symptoms like vomiting and epigastric pain.
  • Conventional diagnostics like radiography and endoscopy often exclude structural abnormalities in these cases.
  • Gastric electrical activity and emptying are key indicators of gastrointestinal function.

Purpose of the Study:

  • To investigate gastric electrical activity and emptying in children with unexplained recurrent upper intestinal symptoms.
  • To assess the utility of electrogastrography (EGG) and ultrasonography in diagnosing these pediatric patients.
  • To identify potential biomarkers for upper gastrointestinal dysfunction in children.

Main Methods:

  • Electrogastrography (EGG) recorded gastric electrical activity in 14 children and 10 controls.

  • Gastric emptying time was measured using real-time ultrasonography in all subjects.
  • Patients underwent radiography and endoscopy to rule out structural abnormalities.

    • Main Results:

    • Patients exhibited significantly prolonged gastric emptying times compared to controls.
    • Abnormal gastric electrical rhythms (tachygastria, bradygastria, arrhythmias) were prevalent in patients during both fasting and fed states.
    • EGG analysis revealed reduced normal frequency activity and increased abnormal low and high frequencies in patients.

    Conclusions:

    • A high proportion of children with unexplained recurrent upper gastrointestinal symptoms show gastric electrical abnormalities.
    • Electrogastrography (EGG) is a valuable diagnostic tool for assessing children with these functional gastrointestinal disorders.
    • Abnormalities in gastric electrical activity and delayed gastric emptying are significant findings in this pediatric population.
