Sponsor's own description

This study is to evaluate the correlation of adenoma missing rate and quality indicators of colonoscopy including adenoma detection ratee (ADR), polyp detection rate (PDR), adenoma per colonoscopy rate (APC), adenoma per positive participant (APP), ADR-Plus, and to find out the surrogate indicators of ADR. This study is a prospective observational multi-center study. Correlation between AMR and quality indicators of colonoscopy based on the previous studies, 8 endoscopists participated in this study and will enroll 50 screening colonoscopies respectively. Recruit research participants who want to participate in research in outpatient clinics. Perform colonoscopy in the morning after colon cleansing with split method. Colonoscopy is performed by back-to-back two consecutive colonoscopies. When the first colonoscopy is performed, the colonoscope is retracted after inserting the cecum, and all colon polyps are removed. After retracting to the anus of the first colonoscopy, the second colonoscopy is performed immediately. In case of newly detected colon polyps except for the small polyps and S-colon and rectal polyps which were left as photographs during the first colonoscopy with the second colonoscopy, we regard them as an overlooked lesion during the first colonoscopy. After the procedure, the histologic examination is confirmed and classified as benign lesions (all adenomas, advanced adenomas, dysplasia, and colorectal cancer) and non-lesion lesions. Using the back-to-back colonoscopy results of the participants during the study period, calculate the quality indicators including ADR, PDR, APC, ADR-plus, APP and AMR for each endoscopist. And then, evaluate the correlation between AMR and other quality indicators.
