Barrett's esophagus (BE), a complication of chronic reflux, involves intestinal metaplasia in the esophagus and is linked to increased esophageal cancer risk. Regular endoscopic surveillance is recommended for BE patients, but not for cardia intestinal metaplasia (CIM).

Area of Science:

  • Gastroenterology
  • Oncology
  • Gastrointestinal Pathology

Background:

  • Barrett's esophagus (BE) is a complication of chronic gastroesophageal reflux disease (GERD).
  • BE is characterized by intestinal metaplasia in the esophagus and is associated with an increased risk of esophageal adenocarcinoma.
  • The incidence of esophageal adenocarcinoma has significantly increased in recent decades.

Purpose of the Study:

  • To summarize the current understanding and management of Barrett's esophagus.
  • To highlight the association between BE and esophageal adenocarcinoma.
  • To provide guidance on surveillance and treatment strategies.

Main Methods:

  • Review of existing literature on Barrett's esophagus and related conditions.
  • Analysis of the association between BE and esophageal adenocarcinoma.

  • Discussion of diagnostic and therapeutic modalities.

    • Main Results:

    • BE affects approximately 1% of individuals over 60 and may have a genetic predisposition.
    • Esophageal adenocarcinoma incidence is rising, with a known link to BE.
    • Cardia intestinal metaplasia (CIM) is mentioned, but surveillance is not advised.
    • Chromoendoscopy can aid in detecting high-grade dysplasia (HGD).
    • Ablation therapies for BE are not yet proven to reduce cancer risk.
    • Esophagectomy remains the standard for HGD; endoscopic resection with or without ablation is an option for localized HGD.

    Conclusions:

    • Barrett's esophagus requires regular endoscopic and histologic follow-up due to its association with esophageal adenocarcinoma.
    • While ablation therapies are being explored, their efficacy in reducing cancer risk is unproven.
    • Management strategies for high-grade dysplasia in BE include esophagectomy and endoscopic interventions.
