Barrett esophagus diagnosis and treatment are advancing with new technologies and biomarkers. Research continues to explore optimal surveillance and the role of acid suppression for this premalignant condition.

Area of Science:

  • Gastroenterology
  • Oncology
  • Pathology

Background:

  • Barrett esophagus is a premalignant condition linked to esophageal adenocarcinoma.
  • While esophageal adenocarcinoma incidence is rising, Barrett esophagus frequency trends are unclear.
  • Bile reflux, often with acid, is implicated in Barrett esophagus pathogenesis.

Purpose of the Study:

  • To review current knowledge on Barrett esophagus epidemiology, pathogenesis, diagnosis, and treatment.
  • To highlight advancements in diagnostic technologies and biomarker research.
  • To discuss controversies in surveillance and management.

Main Methods:

  • Literature review of publications on Barrett esophagus.
  • Discussion of emerging technologies like chromoendoscopy and optical coherence tomography.

  • Exploration of biomarker applications for risk stratification.

    • Main Results:

    • New endoscopic techniques offer more accurate "nonbiopsy" diagnosis of intestinal metaplasia and dysplasia.
    • Biomarkers are improving risk stratification for patients.
    • The role of acid suppression and surveillance endoscopy remains debated, with ongoing research.

    Conclusions:

    • Advancements in technology and biomarkers enhance Barrett esophagus diagnosis and risk assessment.
    • Further prospective data are needed to resolve controversies in surveillance and acid suppression therapy.
    • Endoscopic therapies show promise for managing Barrett esophagus.
