Scope:CF-EZ1500DI
Case: Sessile serrated adenoma
Organ: Colon
Patient information: M, 69
Medical history: Preventive colonoscopy
1. WLI Overview
Thickening of fold indicates a lesion extending on a fold at 2 o’clock
2. TXI™ Technology 1 Overview
TXI™ Technology increases brightness and color contrast. However, visibility of the lesion is not amplified sufficiently.
3. NBI™ Technology Overview
With NBI™ Technology, the color contrast between healthy background mucosa and the lesion is most comprehensive in this case.
4. Approach with NBI™ technology
With NBI™ Technology, we can observe areas with high and low vessels density and irregular pattern.
5. Near Focus mode with NBI™ Technology
Near Focus mode + 1.6x electronic zoom supports a histology prediction of adenoma with high degree of irregularity (JNET 2B).
6. Near Focus mode with NBI™ Technology
Near Focus mode + 1.6x electronic zoom reveals adenoma with high degree of irregularity (JNET 2B).

Overall Comment
In my opinion, NBI™ Technology was most helpful to identify and characterize the lesion underlining existing evidence that it is working well if the colon is clean. Near Focus are easy to use to characterize and predict endoscopic resectability of the lesion through application of the JNET classification with NBI™ technology.
