Randomised controlled trial comparing modified Sano’s and narrow band imaging international colorectal endoscopic classifications for colorectal lesions

Figure 1 Modified Sano’s classification is defined as below. ¹If no open pits and 2 serrated features = classified as low confidence for SSA/P; if 1 serrated feature = low confidence for HP; if no features = high confidence for HP. ²Can have slight loss of pit pattern and vascularity when leaning towards superficial cancer.MS:Modified Sano’s; HP: hyperplastic polyp; SSA/P: Sessile serrated adenoma/polyp.

A: For neoplastic differentiation; B: For endoscopic resectability. MS: Modified Sano’s; NICE: Narrow band imaging international colorectal endoscopic; SSA/P: Sessile serrated adenoma/polyp.
