Developmental phase

Assessment
Primary outcomes Adenoma detection rate per one colonoscopy
Key secondary outcomes 1. Flat and depressed tumor detection rate per colonoscopy
2. Detection rate of advanced adenoma per colonoscopy
Advanced adenoma is an adenoma of 10 mm or more, histopathologically villous or tubulovillous component, and high-grade dysplasia.
3. Sessile serrated lesion (SSL) detection rate per colonoscopy
4. Diminutive adenoma detection rate
5. Polyp detection rate
6. Mean number of adenomas per procedure (MAP)
7. Total observation time (including treatment time) from reaching the cecum to withdrawal through the anus.
8. Incident rate
9. Medical cost per examination (treatment-related costs/pathological diagnosis costs)
10. Rate of post colonoscopy colorectal cancer and advanced adenoma

Other
Other related information The colonoscopy performed from June 2020 to March 2025 is the target. The patients have performed the colonoscopy with the standard protocol. After the endoscope reaches the cecum, the doctor presses the analysis start button on the ENDOBRAIN-EYE, and thereafter withdrawal of the endoscope while carefully observing the mucosae. The lesions found during the withdrawal are observed and then the treatment strategy is determined based on the doctor's judgment. If it is determined that the resection of the lesions is necessary, the resection is performed on the same day or at a later date and sent to the pathological diagnosis. The doctor will enter the lesion site, size, and morphology found after the colonoscopy in the medical record as usual. At this time, no new information specific to this study is acquired.
This sequence is the usual practice, with no intervention. ENDOBRAIN-EYE is installed in the 10th, 8th, 7th, and 6th examination rooms of the digestive center endoscopy room, and it operates only on Monday, Wednesday, and Friday due to software maintenance reasons. In this study, the group that did not use ENDOBRAIN-EYE is treated as a comparison.
