Follow the Seattle protocol in Barrett's surveillance

Take four-quadrant biopsies every 2 cm of Barrett's segment, plus targeted biopsies of any visible lesion, after careful inspection.

Standard Barrett's surveillance combines careful high-definition inspection with targeted biopsy of visible lesions and four-quadrant random biopsies every 2 cm. Recording the Prague classification allows comparison over time.

Adjuncts should be judged on whether they increase confirmed neoplasia, not suspicious findings.

  • Clean the mucosa and inspect with high-definition white light before biopsy.
  • Record segment length using Prague C and M criteria.
  • Biopsy visible lesions first, then four-quadrant samples.
  • Allow enough inspection time; longer inspection is linked to higher detection.

Why it matters

Dysplasia is often invisible, and random biopsy at fixed intervals finds lesions that inspection alone misses.
