In 2020, the British Society of Gastroenterology (BSG), the Association of Coloproctology of Great Britain and Ireland (ACPGBI) and Public Health England (PHE) released joint guidelines for surveillance after polypectomy and colorectal cancer resection.  According to the guidelines, the criteria for high-risk for future colorectal cancer (CRC) following polypectomy comprise either of the following [161] :

  • Two or more premalignant polyps, including at least one advanced colorectal polyp (defined as a serrated polyp of at least 10 mm in size or containing any grade of dysplasia, or an adenoma of at least 10 mm in size or containing high-grade dysplasia)  or
  • Five or more premalignant polyps

Patients who meet the high-risk criteria should undergo a single surveillance colonoscopy at 3 years.  Patients who have undergone CRC resection should have a colonoscopy at 1 year post-surgery and every 3 years thereafter. [161]

Patients who do not meet high-risk criteria postpolypectomy should participate in national bowel screening when invited. For patients who are more than 10 years younger than the national bowel screening lower age limit, colonoscopy may be considered after 5 or 10 years and individualized to age and other risk factors. [161]
