Most validation studies of the two new NBI classifications were conducted in classification setting units by experienced endoscopists, and the application of use in different centers among endoscopists with different endoscopy skills remains unknown.

Aim

Methods

Six endoscopists with varying levels of experience participated in this study. Eighty-seven consecutive patients with a total of 125 l
