Motor function abnormalities in acute caustic esophagitis

M Guelrud, M Arocha

    Journal of Clinical Gastroenterology
    |September 1, 1980
    PubMed
    Summary

    Acid-induced esophageal injury causes motor abnormalities, particularly in severe cases, leading to difficulty swallowing (dysphagia). Esophageal motor function typically recovers within a month following the injury.

    Area of Science:

    • Gastroenterology
    • Esophageal Motility Disorders

    Background:

    • Acid ingestion can cause caustic esophagitis, leading to esophageal damage.
    • Esophageal motor function may be affected by chemical injury.

    Purpose of the Study:

    • To investigate the correlation between the severity of acid-induced esophageal injury and motor abnormalities.
    • To characterize esophageal motor function during and after caustic esophagitis.

    Main Methods:

    • Esophagoscopy was used to assess mucosal damage.
    • Esophageal manometry was performed to evaluate motor function, including resting pressure of the lower esophageal sphincter and esophageal body contractions.
    • Follow-up manometry was conducted 1 month after injury.

    Main Results:

    • Mild caustic esophagitis showed normal esophageal motor function.
    • Severe esophagitis was associated with decreased or absent lower esophageal sphincter resting pressure and variable abnormalities in the esophageal body, such as high resting pressure, absent or non-peristaltic contractions, and delayed responses to swallowing.
    • Esophageal motor function returned to normal in follow-up studies one month post-injury.

    Conclusions:

    • Acid-induced esophageal injury, especially severe cases, leads to significant motor abnormalities.
    • These motor dysfunctions, potentially due to edema or transient nerve damage, likely contribute to dysphagia.
    • Esophageal motor function demonstrates recovery within one month after the initial injury.
