Endoscopic management of colorectal polyps: From benign to malignant polyps

Table 1 Narrow-Band Imaging International Colorectal Endoscopic classification system

	Color	Vessels	Pits	Association
Type 1	Same or lighter than background	No or lacy vessels	Dark or white spots of uniform size	Hyperplastic or serrated polyps
Type 2	Browner than background	Brown vessels	Oval or tubular white pits	Adenomatous polyps
Type 3	Dark brown	Disrupted or missing vessels	Amorphous or absent pits	Deep submucosal invasion

This system uses color, vessel and surface pattern on Narrow-band imaging to predict the most likely polyp histology
