NCT04831814

Brief Summary

Optical diagnosis of colorectal polyps is a promising tool to avoid risks of unnecessary polypectomies and to save costs of tissue pathology. NICE (NBI International Colorectal Endoscopic) and WASP (Workgroup on Serrated Polyps and Polyposis) classification were developed for diagnosis of adenomatous and sessile serrated polyps, respectively.

Outcome Measures

Primary Outcomes (2)

  • Rate of accurate polyp histology predictions by the Endoscopists in the two groups.

    Measure of the percentage of accurate predictions by the endoscopists in the differentiation of neoplastic from non neoplastic colorectal lesions, using the high definition NBI colonoscopy with and without near focus features

    At the time of procedure

  • Rate of accurate diagnosis of sessile serrated polyps/adenoma by the Endoscopists in the two groups.

    Measure of the percentage od accurate predictions by the endoscopists in the differentiation of sessile serrated polyps/adenoma from hyperplastic polyps, using the high definition NBI colonoscopy with and without near focus features.

    At the time of procedure

Secondary Outcomes (3)

  • The polyp detection rate

    At the time of procedure
