Antral mucosal diaphragms in adults.

J L Clements, J R Jinkins, W E Torres

    AJR. American Journal of Roentgenology
    |December 1, 1979
    PubMed
    Summary

    Antral mucosal diaphragms, often asymptomatic, are likely congenital, not acquired from peptic ulcers. Radiologic techniques aid in evaluating gastric outlet obstruction caused by these diaphragms.

    Area of Science:

    • Gastroenterology
    • Radiology
    • Anatomical Pathology

    Background:

    • Antral mucosal diaphragm is a rare gastric anomaly.
    • Its etiology (congenital vs. acquired) remains debated, particularly its relationship with peptic ulcer disease.

    Purpose of the Study:

    • To investigate the nature and prevalence of antral mucosal diaphragms.
    • To describe diagnostic radiologic techniques for evaluating gastric outlet obstruction caused by these diaphragms.

    Main Methods:

    • Retrospective review of 53 patients diagnosed with antral mucosal diaphragm.
    • Autopsy study of 29 unselected cases to assess diaphragm prevalence and morphology.
    • Description of radiologic evaluations including compressed barium tablet and "barium burger" examinations.

    Main Results:

    • Over 50% of diagnosed diaphragms were asymptomatic.
    • Autopsy revealed five antral mucosal diaphragms in various forms.
    • Findings suggest the diaphragm is a congenital anomaly, not acquired secondary to peptic ulcer disease.

    Conclusions:

    • The antral mucosal diaphragm is likely a congenital condition in adults.
    • Radiologic methods are effective for diagnosing diaphragms and assessing associated gastric outlet obstruction.
