Use of electrogastrography in children

Area of Science:

• Gastroenterology
• Electrophysiology
• Medical Diagnostics

Background:

• Electrogastrography (EGG) is a noninvasive method measuring gastric electrical activity using surface electrodes.
• Gastric slow waves, primarily at three cycles per minute, are generated by interstitial cells of Cajal and are vital for coordinated gastric motility.
• Advances in EGG technology enhance its utility in studying functional gastrointestinal disturbances.

Purpose of the Study:

• To review the principles and applications of Electrogastrography (EGG).
• To highlight the role of interstitial cells of Cajal in gastric electrical activity.
• To discuss the diagnostic potential of EGG in functional gastrointestinal disorders and pediatric populations.

Main Methods:

• Surface electrode placement to record gastric electrical activity.
• Analysis of gastric slow wave frequency, stability, and postprandial changes.
• Establishment of pediatric norms and postnatal EGG changes.

Main Results:

• EGG provides a noninvasive assessment of gastric pacemaking activity.
• EGG parameters like frequency distribution and signal stability are quantifiable.
• Pediatric norms and postnatal changes in EGG have been defined, supporting further research.

Conclusions:

• Electrogastrography is a promising tool for diagnosing gastrointestinal motility disorders.
• Further research is needed to fully elucidate EGG's role in identifying interstitial cells of Cajal dysfunction.
• EGG applications are expanding, particularly in functional gastrointestinal disturbances and infant studies.
