Table 1 Narrow band imaging international colorectal endoscopic classification of colorectal polyps was based on 3 features including colour, vessel, architecture and surface pattern
NICE I | NICE II | NICE III | |
Colour | Same or lighter than background | Browner than background | Dark brown relative to background +/- patchy whiter areas |
Vessels | None or isolated lacy vessels | Brown vessels surrounding white structures | Disrupted or missing vessels |
Surface pattern | Dark or white spots of uniform size, or homogeneous absence of pattern | Oval, tubular or branched white structure surrounded by brown vessels | Amorphous or absent surface pattern |
Likely pathology | Hyperplastic | Adenoma | Deep submucosal invasive cancer |
