AGA Institute GastroSlides Unit on Barrett’s Esophagus



This teaching unit consists of 298 images that review the epidemiology, pathogenesis, molecular biology and treatment of Barrett’s esophagus. This multimedia unit includes animations, endoscopic images, new techniques to detect metaplasia and dysplasia (e.g. chromoendoscopy and spectroscopy), histology, and videos demonstrating endoscopic ablation and endoscopic mucosal resection. The unit is divided into six sections:

  1. Diagnosis and epidemiology of Barrett’s esophagus. This section highlights the prevalence of Barrett’s esophagus, its association with different factors, and the anatomical landmarks and histological findings required for diagnosis.
  2. Pathogenesis of Barrett’s development. This section reviews normal esophageal physiology, and abnormalities in lower esophageal sphincter function, hiatal hernias and other abnormalities of the distal esophagus that are associated with the development of Barrett’s esophagus.
  3. Progression of epithelial metaplasia to neoplasia. This section highlights the molecular mechanisms underlying progression of Barrett’s epithelium to dysplasia and cancer, with descriptive histology of the grades of dysplasia and cancer. Endoscopic photographs of lesions suspicious for cancer within Barrett’s mucosa and molecular markers that are associated with progression to cancer are included.
  4. Screening and surveillance in Barrett’s esophagus. This section reviews the epidemiology of esophageal adenocarcinoma, clinical risk factors associated with progression of Barrett’s epithelium to dysplasia and cancer, and different modalities for screening and surveillance.
  5. Treatment of Barrett’s esophagus and adenocarcinoma. This section reviews medical treatment (including chemoprevention), surgery and various endoscopic modalities.
  6. Barrett`s cases.
