Clinical Trial Summary

The purpose of this prospective, non-interventional study is to validate the Narrow Band Imaging International Colorectal Endoscopic (NICE) classification for differentiating subcentimetric hyperplastic and adenomatous polyps by using Fuji Intelligent Color Enhancement (FICE) technology with high-definition without optical magnification.


Description:

1. In order to create a video-library of endoscopic cases, patients undergoing screening or diagnostic colonoscopy will be considered for inclusion. Patients with at least one histologically verified <10 mm polyp will be included. A short video-clip (around 15-20 seconds) of each polyp both at white-light and FICE-light will be recorded and stored in an anonymized database.

2. Once the video-library is completed, each of 7 experts will independently review all the cases. For each case, any observer will assess each of the three NICE criteria (colour/vascularization/surface), the degree of confidence (low/high), and classify the lesion as neoplastic or non-neoplastic. The primary outcomes are the accuracy of FICE technology with high-definition and without magnification, when adopting NICE classification, to differentiate between hyperplastic and adenomatous lesions, and the inter-observer agreement in such differentiation. Secondary end-points are to assess at multivariate measure the role of any individual criteria of NICE classification in the discrimination between the two histotypes, and possible adaptations of NICE classification in order to be applied with FICE.

Outcome

Type Measure Description Time frame Safety issue
Other Accuracy of additional criteria, such as the presence of mucus, to differentiate between sub-types of non-neoplastic lesions (i.e. serrated lesions) up to 6 month No
Primary accuracy of the NICE criteria using FICE technology for differentiating between the non-neoplastic and neoplastic histotypes in diagnoses with high-confidence on a video-library of 110 polyps reviewed by 7 experts. 7 experts will review videos from a video-library of subcentimetric polyps removed and histologically verified and will assess each of the three NICE criteria (colour/vascularization/surface), and classify the lesion as neoplastic or non-neoplastic with low or high confidence. up to 6 months No
Primary Inter-observer agreement among the 7 experts The inter-observer agreement, among the 7 experts, on the final diagnosis (neoplastic or non-neoplastic) and on each individual NICE criterion for each polyp will be determined by using K statistics . up to 6 months No
