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

This is a teaching session on how to identify the colorectal polyps shot in blue light imaging.
Registry-reported names are shown in full. Names without a link have not yet been matched to a Syfrah profile.
Study participants are contacted while they are at the VA medical centre. All gastroenterology attending physicians, gastroenterology fellows, residents and medical students will be notified about the study and asked about the willingness to participate if they fit the inclusion/exclusion criteria. Practicing gastroenterologists and trainees will be contacted and inquired about their intent of participating in the assessment of images/videos. This is a voluntary project and not a part of any mandatory training. There is no coercion of participants who do not want to participate. This study includes only the images and videos from standard pre-existing database. This database was developed by European investigators for educational purposes. This information has no patient identifiable parameters. This information is stored in a secure server with guarded access.
