Haematemesis: a new syndrome?

A T Axon, A Clarke

    British Medical Journal
    |March 1, 1975
    PubMed
    Summary

    A Mallory-Weiss tear, a cause of upper gastrointestinal bleeding, may result from retrograde gastric intussusception during vomiting. This condition presents with characteristic endoscopic findings near the gastroesophageal junction.

    Area of Science:

    • Gastroenterology
    • Internal Medicine
    • Clinical Diagnostics

    Background:

    • Mallory-Weiss tears are a recognized cause of upper gastrointestinal hemorrhage.
    • The etiology of Mallory-Weiss tears is often associated with forceful retching or vomiting.
    • Diagnostic challenges can arise in identifying the precise cause of mucosal lesions in the gastroesophageal region.

    Purpose of the Study:

    • To describe a potential novel mechanism for Mallory-Weiss tears.
    • To correlate clinical presentation with endoscopic findings in patients with suspected Mallory-Weiss tears.
    • To investigate the role of retrograde gastric intussusception in gastroesophageal mucosal injury.

    Main Methods:

    • Case series review of three patients presenting with symptoms suggestive of Mallory-Weiss tear.
    • Endoscopic examination of the gastroesophageal junction.
    • Histopathological analysis of mucosal findings (implied).

    Main Results:

    • Endoscopy revealed a localized, demarcated area of bright red mucosa in all three patients.
    • The observed mucosal changes were located near the gastroesophageal junction.
    • The findings were consistent with retrograde intussusception of the stomach.

    Conclusions:

    • Retrograde intussusception of the stomach during vomiting or retching is a plausible mechanism for Mallory-Weiss tears.
    • This mechanism can explain the observed endoscopic findings of localized mucosal injury.
    • Further research is warranted to confirm this association and its clinical implications for hemorrhage management.
