Core Tip
Core tip: This is the first review of the Japan Narrow Band Imaging Expert Team classification regarding the diagnostic performance. There are three important differentiations: neoplasia from non-neoplasia, malignant neoplasia from benign neoplasia, and deep submucosal invasive cancer (D-SMC) from other neoplasia. The sensitivity in differentiating neoplasia from non-neoplasia was 98.1%-99.8%. The specificity in differentiating malignant neoplasia from benign neoplasia was 84.7%-98.2% and the specificity in differentiating D-SMC from other neoplasia was 99.8%-100.0%. This classification will enable endoscopists to identify almost all neoplasia, to appropriately determine whether to perform en bloc resection or not, and to avoid unnecessary surgery.
