NCT04510545

Brief Summary

The purpose of this study is to assess whether computer aided technology (CAD) can help in the diagnosis of polyps found the bowel compared with visual inspection alone and therefore whether it is beneficial in helping clinicians to decide whether to remove a polyp or not. Presently, most endoscopists remove all polyps found and send them to the laboratory for testing. The number of colonoscopies is increasing, meaning that more polyps are detected and removed. This comes at a significant cost to the health service and increases the time taken to complete a colonoscopy.

Outcome Measures

Primary Outcomes (1)

  • True positive adenoma detection rate

    True positive adenoma detection rate with visual inspection versus true positive adenoma detection rate with visual inspection plus CAD

    6 months

Secondary Outcomes (7)

  • True negative adenoma detection rate

    6 months

  • To estimate the sensitivity, specificity, of visual inspection and the use of the EndoBRAIN CAD technology

    6 months

  • To estimate the positive predictive value [PPV], and NPV of the combination of visual inspection and the use of the EndoBRAIN CAD technology

    6 months

  • To estimate the percentage of diminutive colorectal polyps from which endocytoscopic images can be successfully captured (acquisition rate).

    6 months

  • To estimate the rate of high-confidence diagnosis with EndoBRAIN as compared to visual polyp inspection alone.

    6 months

  • +2 more secondary outcomes
