Grade of dysplasia | ACG | ASGE | AGA | BSG | SFED |
---|---|---|---|---|---|
NDBO | Two OGDs within first year, then every 3 years if no dysplasia | Consider no surveillance. If surveillance is elected, OGD every 3–5 years | OGD every 3–5 years | SSBO (<3 cm): OGD every 3–5 years LSBO (> 3 cm): OGD every 2–3 years | SSBO (< 3 cm): OGD every 5 years LSBO (3–6 cm): OGD every 3 years LSBO (> 6 cm): OGD every 2 years |
LGD* | Repeat OGD within 6 months; if no HGD, then every 1 year | Repeat OGD within 6 months; if no HGD, then every 1 year | OGD every 6–12 months | Repeat OGD within 3 months; if no HGD, then every 6 months | Repeat OGD. If LGD confirmed, OGD at 6 months, 1 year, then yearly |
HGD* | Repeat OGD within 3 months, then every 3 months or consider endoscopic therapy | Consider repeat OGD within 3 months or endoscopic therapy | OGD every 3 months in the absence of endoscopic therapy | Consider endoscopic therapy | Repeat OGD. If HGD confirmed, endoscopic or surgical treatment |
