Clinical Trial Summary

This is a prospective equivalence colonoscopy study evaluating whether overall adenoma detection rate (ADR) is a reliable alternate for screening ADR. Overall indication includes screening, surveillance, and diagnostic indications.


Clinical Trial Description

This is a multicenter study conducted by 18 colonoscopists from 5 hospitals in Taiwan, including Evergreen general hospital, E-da hospital, E-da Dachang hospital, Linkou Chang Gung memorial hospital, and Keelung memorial hospital. Felix W. Leung has been involved in the study design, and will participate in data analyses and report preparation, but not in patient enrollment. Consecutive patients aged ≥50 years undergoing colonoscopy are eligible for enrollment. Positive fecal immunochemical test (FIT+) is considered as an independent indication category and the colonoscopy indications are categorized into 4 groups: screening, surveillance, diagnostic, and FIT+. Overall indication will be subdivided into overall excluding FIT (overall-non-FIT) group and overall including FIT (overall-FIT) group. In this study, we plan to (1) compare individual ADR across 4 colonoscopy indication categories (screening, surveillance, diagnostic, FIT+); (2) explore correlations between screening ADR and overall-non-FIT and overall-FIT ADRs, respectively. ;
