Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In the first phase of the study, a learning program of NICE classification based on examples will be performed. Forty images will be evaluated before and after the learning program.

In the second phase of the study, all consecutive patients who underwent to a colonoscopy will be included if a lesion greater than 1 cm is found and the endoscopy is performed with a high definition colonoscope with Narrow Band Imaging (NBI). Patients, lesions and endoscopy equipment characteristics will be recorded.

Subsequently, histological diagnosis of the lesion will also be recorded. Evaluated test (NICE classification) was blinded to the pathologist who performed the gold standard test (histology). In case of adenocarcinomas, histological predictors of lymph node metastases, with predefined assessment criteria, will also be recorded.

Finally, histological preparations of adenocarcinomas will be sent to the reference center and two experienced pathologists will examine them again.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

NBI used by trained endoscopists

Assessment with NICE classification and NBI technology of colonic lesions (Paris classification type 0) greater than 1 cm found in a routine colonoscopy. This assessment was performed by previously trained endoscopists.

Group Type EXPERIMENTAL

NBI used by trained endoscopists

Intervention Type DEVICE

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.
