What is the recommended surveillance interval for Barrett's esophagus with no dysplasia?

• A. 1 year
• B. 2 years
• C. 3-5 years
• D. 10 years

Answer: (C)

In Barrett's esophagus without dysplasia, the cancer risk is low, so surveillance endoscopy can be spaced out. The goal is to detect any progression early while avoiding unnecessary procedures. Therefore the recommended interval is endoscopy every 3 to 5 years. Shorter intervals (like 1 year) are more aggressive than needed for nondysplastic BE, while waiting 10 years could miss progression. If dysplasia is present, the approach changes and surveillance becomes more frequent or involves treatment.
