It exists a learning curve in using NBI with magnification to differentiating colorectal lesions.
It is very useful to use narrow-band imaging and Sano CP analysis in the differential diagnosis of colorectal lesions. The endoscopists who had never used NBI or no knowledge of NBI can have effective and stable diagnostic accuracy after using NBI with magnification to diagnose 15 target and non-target lesions respectively.

if the lesion is neoplastic or sm deeper cancer, we just take biopsy.If the lesion is adenomatous or sm1-2 cancer,we do polypectomy, EMR or ESD to get the specimen.
