a

The BSG/ACPGBI/PHE recommend a second site check 18 months after the original resection.

b

Surveillance at 3 years is recommended if there are two or more premalignant polyps, of which at least one is advanced (surveillance at 3 years would not be recommended if the patient has only one of these adenomas/SSPs).
