J C Mangla

    Journal of Clinical Gastroenterology
    |December 1, 1981
    PubMed
    Summary

    Barrett's esophagus, a complication of reflux esophagitis, is more common than previously thought. Advances in understanding and treatment offer improved outcomes for this condition and associated adenocarcinoma.

    Area of Science:

    • Gastroenterology
    • Oncology
    • Digestive Diseases

    Background:

    • Barrett's esophagus is an acquired complication of chronic reflux esophagitis.
    • The metaplastic esophageal epithelium is susceptible to inflammation, ulceration, stricture, and adenocarcinoma.
    • Recent advances have shed light on the pathophysiology and management of this condition.

    Purpose of the Study:

    • To review recent advances in understanding Barrett's esophagus.
    • To highlight the prevalence and complications of Barrett's esophagus.
    • To discuss current diagnostic and therapeutic strategies.

    Main Methods:

    • Review of current literature on Barrett's esophagus.
    • Analysis of evidence regarding the etiology and pathogenesis.
    • Evaluation of diagnostic tools like pertechnetate scintigraphy.
    • Assessment of treatment outcomes for anti-reflux surgery and medical management.

    Main Results:

    • Barrett's esophagus is more prevalent than often recognized by clinicians.
    • The heterotopic epithelium exhibits specialized cells and secretory functions (pepsin, acid, gastrin).
    • Anti-reflux surgery effectively halts epithelial progression and promotes mucosal healing.
    • Medical therapies (cimetidine, bethanechol) can aid in healing inflamed mucosa.

    Conclusions:

    • Barrett's esophagus requires increased clinical awareness due to its prevalence and malignant potential.
    • Effective management strategies, including surgical and medical interventions, can mitigate complications.
    • Adenocarcinoma arising in Barrett's esophagus may possess a more favorable prognosis compared to other esophageal cancers.
