  • Abstract
  • Look Inside
  • Reference

 The Japan Esophageal Society-Barrett's esophagus working group(JES-BE)proposed a new magnification endoscopy classification system for the diagnosis of superficial Barrett's esophagus-related neoplasia. This nationwide multicenter study aimed to validate the diagnostic accuracy and reproducibility of the magnification endoscopy classification system, including the diagnostic flowchart. The results showed high diagnostic accuracy and reproducibility for both experts and non-experts. No significant difference in the diagnostic accuracy and reproducibility was found between experts and non-experts. The JES-BE classification system, including the diagnostic flowchart for predicting dysplastic BE, is acceptable and reliable, regardless of the clinician's experience level.
