Guidelines for endoscopic surveillance of Barrett’s oesophagus (BO) by major gastroenterological societies.

Grade of dysplasia	ACG	ASGE	AGA	BSG	SFED
NDBO	2 OGD within first year, then every 3 years if still NDBO	2 OGD within first year, then every 3 years if still NDBO	2 OGD within first year, then every 3–5 years if still NDBO	OGD every 2 years if still NDBO	SSBO (< 3 cm): OGD every 5 yearsLSBO (3 – 6 cm): OGD every 3 yearsLSBO (> 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	Repeat OGD within 6 months; if no HGD, then every 6–12 months	Repeat OGD within 3 months; if no HGD, then every 6 months	Repeat OGD. If low grade confirmed, OGD at 6 months, 1 year, then yearly
HGD	Repeat OGD within 3 months to rule out OAC, then every 3 months or endoscopic/surgical therapy	Repeat OGD within 3 months to rule out OAC, then every 3 months or endoscopic/surgical therapy	Repeat OGD within 3 months to rule out OAC, then every 3 months or endoscopic/surgical therapy	Repeat OGD within 3 months to rule out OAC, then every 3 months or endoscopic/surgical therapy	Repeat OGD.If high grade confirmed, endoscopic or surgical treatment

NDBO: non dysplastic Barrett’s oesophagus; LGD: low-grade dysplasia; HGD: high grade dysplasia; OGD: oesophagogastroduodenoscopy; SSBO: short segment BO; LSBO: long segment BO
