Recommended Post-Colonoscopy Surveillance Strategies for Reducing Colorectal Cancer

Risk For patients with normal, high-quality colonoscopy, repeat CRC screening in 10 years. For patients with 1–2 tubular adenomas \u3c10 mm in size completely removed at a high-quality colonoscopy, repeat colonoscopy in 7-10 years. For patients with 3–4 tubular adenomas \u3c10 mm in size in completely removed at a high-quality colonoscopy, repeat colonoscopy in 3-5 years. For patients with 5-10 tubular adenomas \u3c10 mm in size in completely removed at a high-quality colonoscopy, repeat colonoscopy in 3 years. For patients with 1 or more adenomas \u3e10 mm in size in completely removed at a high-quality colonoscopy, repeat colonoscopy in 3 years. For patients with adenoma containing villous histology completely removed at a high-quality colonoscopy, repeat colonoscopy in 3 years. For patients with adenoma containing high grade dysplasia completely removed at a high-quality colonoscopy, repeat colonoscopy in 3 years. For patients with \u3e10 adenomas completely removed at high-quality examination, repeat colonoscopy in 1 year. For patients with ≤20 HPs \u3c10 mm in size in the rectum or sigmoid colon removed at high-quality examination, repeat CRC colonoscopy screening in 10 years. For patients with ≤20 HPs \u3c10 mm in size proximal sigmoid colon removed at high-quality examination, repeat colonoscopy in 10 years. For patients with 1–2 SSPs \u3c10 mm in size completely removed at high-quality examination, repeat colonoscopy in 5-10 years. For patients with TSA completely removed at a high-quality examination, repeat colonoscopy in 3 years. For patients with 3–4 SSPs \u3c10 mm at high-quality examination, repeat colonoscopy in 3-5 years. For patients with any combination of SSPs \u3c10 mm at high-quality examination, repeat colonoscopy in 3 years. For patients with SSP containing dysplasia at a high-quality examination, repeat colonoscopy in 3 years. For patients with piecemeal resection of adenoma or SSP \u3e20 mm, repeat colonoscopy in 6 months
