Outcome Measures

Primary Outcomes (3)

  • Accuracy measures in comparison to the final histopathology in regards to polyps' subtype (neoplastic versus non-neoplastic)

    Comparison of NICE or MS with the final histopathology in regards to polyps' subtype (i.e. non-neoplastic = Hyperplastic Polyp (HP) and neoplastic = Sessile Serrated Adenoma/Polyp (SSA/P), Adenomatous Polyp (AP), Traditional Serrated Adenoma (TSA), superficial cancer and invasive cancer)

    After two weeks of the colonoscopy

  • Accuracy measures in comparison to the final histopathology in regards to polyps' invasiveness

    Comparison of NICE or MS with the final histopathology in regards to invasiveness (SSA/P, AP, TSA or superficial cancer versus invasive cancer)

    After two weeks of the colonoscopy

  • Accuracy measures in comparison to the final histopathology in regards to polyps' subtype (SSA/P versus non-SSA/P)

    Comparison of MS with the final histopathology in regards to SSA/P (SSA/P versus non-SSA/P)

    After two weeks of the colonoscopy

Secondary Outcomes (2)

  • Accuracy in regards to negative predictive value of diminutive distal colorectal polyps

    After two weeks of the colonoscopy

  • Agreement in predicting post-colonoscopy surveillance interval with final histopathology

    Immediately after the colonoscopy (endoscopic) and 2 weeks after (histopathology)
