    Area of Science:

    • Gastroenterology
    • Medical Devices
    • Physiology

    Background:

    • The cutaneous electrogastrogram (EGG) non-invasively records gastric electrical activity using skin surface electrodes.
    • Recent advancements in recording techniques and signal analysis have renewed interest in EGG.
    • Studies suggest EGG alterations correlate with unexplained nausea and vomiting.

    Purpose of the Study:

    • To review the current status of the cutaneous electrogastrogram (EGG).
    • To discuss the diagnostic potential of EGG for gastric disorders.
    • To present the authors' experience using EGG in studying organic gastric diseases.

    Main Methods:

    • Utilized electrodes placed on the abdominal skin surface to record gastric electrical activity.
    • Reviewed recent developments in EGG recording techniques and signal analysis.
    • Applied cutaneous EGG in the study of specific organic gastric diseases.

    Main Results:

    • Demonstrated that alterations in gastric electrical activity can accompany unexplained nausea and vomiting.
    • Highlighted the diagnostic potential of cutaneous EGG.
    • Identified existing challenges hindering widespread clinical adoption of EGG.

    Conclusions:

    • Cutaneous electrogastrogram (EGG) shows promise for diagnosing gastric issues, particularly nausea and vomiting.
    • Further research and technical improvements are necessary to overcome current limitations for clinical application.
    • EGG is a valuable tool for investigating organic gastric diseases.
