Diagnostic Accuracy of NICE Classification to Predict Deep Submucosal Invasion

Summary

The purpose of this study is to evaluate the diagnostic accuracy of NICE classification to predict deep submucosal invasion of colonic polyps \> 1 cm, considering histology as the gold standard, in a group of endoscopists who previously performed a training program.

Conditions

• Colonic Polyps

Interventions

DEVICE

NBI used by trained endoscopists

Examination of colon lesions, using NBI and NICE classification, by endoscopists who previously performed an easy learning program. The learning program consists on the reading of two reference articles and a tutorial explaining the NICE classification. This tutorial shows several lesions and describes the characteristic features in which the classifications focus on.
