Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Two experienced endoscopists (YHH and CWT) performed all the recorded colonoscopies. Recordings will be selected for review if they are complete examinations; include clear identification of the appendiceal orifice and/or the ileocecal valve, indicating arrival at the cecum; available in the appropriate format for video editing; and contain no patient or endoscopist identifiers. Patients with incomplete recordings and a history of bowel resection will be excluded from analysis. The included video recordings will be edited to remove the insertion phase to blind the study reviewer to the insertion techniques. One blinded reviewer uninvolved in the performance of the colonoscopies will be in charge of evaluating the selected videos, using the criteria described by Yung et al
