Barrett's esophagus involves intestinal metaplasia in the esophagus, increasing cancer risk. Early detection and treatment, including surgery, can improve survival rates for esophageal adenocarcinoma.

Area of Science:

  • Gastroenterology and Oncology
  • Esophageal diseases
  • Gastrointestinal pathology

Context:

  • Barrett's esophagus (BE) is characterized by the replacement of distal esophageal squamous epithelium with metaplastic columnar epithelium.
  • This condition is a known complication of severe reflux esophagitis and is strongly associated with esophageal adenocarcinoma.
  • Recent interest from Japanese physicians highlights the growing clinical significance of BE.

Purpose:

  • To review the pathophysiology, clinical presentation, and management of Barrett's esophagus.
  • To discuss the association between intestinal metaplasia and the development of esophageal adenocarcinoma.
  • To emphasize the importance of endoscopic surveillance and treatment strategies for BE patients.

Summary:

  • Intestinal metaplasia in BE is thought to arise from multipotential stem cells, with accumulating evidence for a genetic basis in the dysplasia-adenocarcinoma sequence.

  • Both gastric acid and bile reflux can cause esophagitis; proton pump inhibitors alone may not suffice, and antireflux surgery can lead to BE regression in up to 50% of cases.
  • Survival rates after surgical resection for adenocarcinoma arising from BE are 63% (1-year), 41% (2-year), and 32% (5-year), underscoring the need for surveillance.

    • Impact:

    • Highlights the critical link between Barrett's esophagus and esophageal cancer.
    • Suggests that comprehensive management, potentially including surgery, is crucial for improving patient outcomes.
    • Recommends endoscopic surveillance for early detection and intervention in patients with BE.
