Optical diagnosis of diminutive polyps in the Dutch bowel cancer screening program: Are we ready to start?
Table 8.6: Surveillance intervals based on optical diagnosis vs histology, according to: A) the Dutch surveillance guideline (2012); B) the ESGE (European) surveillance guideline (2013); C) the AGA (American) surveillance guideline (2012); applying the "resect and discard” strategy. For this strategy optical diagnosis was used for polyps ≤5 mm in the entire colon while for all other polyps, histological evaluation was used to determine surveillance intervals.
