Interpretation of Endoscopic Characteristics of Colorectal Polyps With Blue Light Imaging

Interpretation of endoscopic characteristics of colorectal polyps with Blue Light Imaging A study of BLI images and videos of colorectal polyps will be presented initially as a training set followed by with explanation and teaching in a didactic session to two separate groups. A post-test will be conducted to look at the quality of the learning experience.

To evaluate the teaching tool regarding the criteria for BLI images of colorectal polyps by the following measures

• Inter-observer agreement between same and different groups
• Accuracy in describing the morphology of colorectal polyps • This new teaching tool will improve
• Inter-observer agreement by at least 5%- 10% (depending on the group)
• Accuracy by at least 5%- 10% (depending on the group)• To determine the improvement of inter-observer agreement in identifying/ describing colorectal polyps after the didactic session in both the groups
• Overall Accuracy, Sensitivity, Specificity, Positive predictive value and negative predictive value pre-and post-test in both the groups
