We analyzed the efficacy of linked color imaging (LCI) by assessing the detection, miss, and visibility of various featured adenomas as compared with white light imaging (WLI). Methods: This was a prospective, randomized, tandem trial. The participants were randomly assigned to 2 groups: first observation by LCI, then second observation by WLI (LCI group); or both observations by WLI (WLI group). Suspected neoplastic lesions were resected after magnifying image-enhanced endoscopy. The primary outcome was to compare the ADR during the first observation. Secondary outcomes included evaluation of adenoma miss rate (AMR) and visibility score. Results: A total of 780 patients were randomized, 700 of whom were included in the final analysis. The ADR was 69.6% and 63.2% in the LCI and WLI groups, respectively, with no significant difference. However, LCI improved the average ADR in low-detectors compared with high-detectors (76.0% vs 55.1%; P \u003c .001). Total AMR was 20.6% in the LCI group, which was significantly lower than that in the WLI group (31.1%) (P \u003c .001). AMR in the LCI group was significantly lower, especially for diminutive adenomas (23.4% vs 35.1%; P \u003c .001) and nonpolypoid lesions (25.6% vs 37.9%; P \u003c .001) compared with the WLI group. Conclusion: Although both methods provided a similar ADR, LCI had a lower AMR than WLI. LCI could benefit endoscopists with lower ADR, an observation that warrants additional study.
