| Guideline (Year of Publication) | Type of Endoscopic Surveillance | Random or Targeted Biopsies |
|---|---|---|
| SCENIC Consensus (2015) [40] | HD recommended If SD, dye-CE recommended If HD, dye-CE suggested |
No consensus |
| SCENIC commentary (2022) [41] | HD-WLE, dye-CE, or VCE | Random limited to highest-risk groups only (PSC, prior dysplasia, atrophic scarred colon, ongoing active inflammation) |
| ECCO Guideline (2017) [27] | HD recommended | Random if WL Targeted only if dye-CE |
| ECCO Guideline (2023) [44] | HD-WLE, dye-CE, or VCE | Targeted biopsies Random in high-risk (PSC or history of dysplasia) |
| ACG Clinical Guideline (2019) [43] | If SD, dye-CE recommended If HD, dye-CE or VCE recommended |
No recommendation |
| AGA Clinical Practice update (2021) [38] |
HD recommended Dye-CE should be considered VCE acceptable alternative if HD |
Random if WL only and all patients with high risk (PSC or history of dysplasia) Targeted if dye-CE or VCE |
| BSG Guideline (2019) [42] | HD recommended If SD, dye-CE recommended If HD, dye-CE suggested NBI not suggested |
