Background. The present study aimed to evaluate the efficacy of linked color imaging (LCI) in diagnosing Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC).Methods. A total of 112 and 12 consecutive patients with BE and EAC were analyzed. The visibility scores of BE and EAC ranging from 4 (excellent visibility) to 0 (not detectable) were evaluated by three trainees and three experts using white light imaging (WLI), LCI mode, and blue laser imaging bright (BLI-b) mode. In addition,L*a*b*color values and color differences (Delta E*) were evaluated using the CIELAB color space system.Results. The visibility score of the BE in LCI mode (2.94 +/- 1.32) was significantly higher than those in WLI (2.46 +/- 1.48) and BLI-b mode (2.35 +/- 1.46) (p<0.01). The color difference (Delta E*) from the adjacent gastric mucosa in LCI mode (17.11 +/- 8.53) was significantly higher than those in other modes (12.52 +/- 9.37in WLI and11.96 +/- 6.59in BLI-b mode,p<0.01). The visibility scores of EAC in LCI mode (2.56 +/- 1.47) and BLI-b mode (2.51 +/- 1.28) were significantly higher than that in WLI (1.64 +/- 1.46) (p<0.01). The color difference (Delta E*) from the adjacent normal Barrett's mucosa in LCI mode (19.96 +/- 7.97) was significantly higher than that in WLI (12.95 +/- 11.86) (p=0.03).Conclusion. The present findings suggest that LCI increases the visibility of BE and EAC and contributes to the improvement of the detection of these lesions.
