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 (ΔE∗) 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) ( < 0.01). The color difference (ΔE∗) from the adjacent gastric mucosa in LCI mode (17.11 ± 8.53) was significantly higher than those in other modes (12.52 ± 9.37 in WLI and 11.96 ± 6.59 in BLI-b mode, < 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) ( < 0.01). The color difference (ΔE∗) 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) ( = 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.
背景
本研究旨在评估联动成像（LCI）在诊断巴雷特食管（BE）和食管腺癌（EAC）中的疗效。
方法
对112例BE患者和12例EAC患者进行分析。由三名实习生和三名专家使用白光成像（WLI）、LCI模式和蓝光成像增强（BLI-b）模式评估BE和EAC的可视性评分，评分范围为4分（可视性极佳）至0分（不可检测）。此外，使用CIELAB颜色空间系统评估L∗a∗b∗颜色值和颜色差异（ΔE∗）。
结果
LCI模式下BE的可视性评分（2.94±1.32）显著高于WLI模式（2.46±1.48）和BLI-b模式（2.35±1.46）（<0.01）。LCI模式下与相邻胃黏膜的颜色差异（ΔE∗）（17.11±8.53）显著高于其他模式（WLI模式下为12.52±9.37，BLI-b模式下为11.96±6.59，<0.01）。LCI模式（2.56±1.47）和BLI-b模式（2.51±1.28）下EAC的可视性评分显著高于WLI模式（1.64±1.46）（<0.01）。LCI模式下与相邻正常巴雷特黏膜的颜色差异（ΔE∗）（19.96±7.97）显著高于WLI模式（12.95±11.86）（P = 0.03）。
结论
目前的研究结果表明，LCI提高了BE和EAC的可视性，并有助于改善这些病变的检测。
