背景/目的：结构和颜色增强（CE）的设置改变了白光成像的视图，并且定期使用预设的低增强设置。本研究的目的是通过内窥镜医师的可见度评分和客观色差 (CD) 值来调查较高的增强设置是否可以增加结直肠病变的可见度。方法：2015年4月至2015年9月，我们分析了27张结直肠病变图片和100个视频。评估结构增强（B3、A3、A5）和CE（CE 0、1、3）的组合，并使用市售软件计算2种相应模式（高增强：A5 + CE3，预设低增强：A3 + CE0）的CD值。视频中对这两种模式进行了评估。所有图片和电影均由 4 名内窥镜医师使用可见度评分进行评分：4 分（优秀）至 1 分（差）。结果：A3 + CE0 (2.74 ± 1.09) 的分数显着低于所有其他较高增强设置的分数，例如 B3 + CE1 (3.11 ± 1.08)、A3 + CE1 (3.33 ± 0.91) 和 A5 + CE3 (3.56 ± 0.74；p < 0.001)。 A5 + CE3 的 CD 值显着高于 A3 + CE0 (20.2 ± 6.9 vs. 12.9 ± 5.6, p < 0.001)。在视频中，A5 + CE3 的分数显着高于 A3 + CE0（3.27 ± 0.83 与 2.53 ± 1.05，p < 0.001）。结论：较高的增强设置可提高结直肠病变的可见度。
Background/Aims: Settings of structure and color enhancement (CE) change view of white light imaging and a preset low enhancement setting is used regularly. The aim of this study was to investigate whether higher enhancement settings increased colorectal lesions’ visibility with endoscopists’ visibility scoring and objective color difference (CD) value. Methods: From April 2015 to September 2015, we analyzed 27 pictures and 100 videos of colorectal lesions. Combinations of structure enhancement (B3, A3, A5) and CE (CE 0, 1, 3) were evaluated and CD values of 2 corresponding modes (high enhancement: A5 + CE3, preset low enhancement: A3 + CE0) were calculated using marketed software. In the video, these 2 modes were evaluated. All pictures and movies were graded by 4 endoscopists using visibility scores: score 4 (excellent) to score 1 (poor). Results: The scores of A3 + CE0 (2.74 ± 1.09) were significantly lower than those of all other higher enhancement settings such as B3 + CE1 (3.11 ± 1.08), A3 + CE1 (3.33 ± 0.91), and A5 + CE3 (3.56 ± 0.74; p < 0.001). The CD value of A5 + CE3 was significantly higher than A3 + CE0 (20.2 ± 6.9 vs. 12.9 ± 5.6, p < 0.001). In the video, the scores for A5 + CE3 were significantly higher than A3 + CE0 (3.27 ± 0.83 vs. 2.53 ± 1.05, p < 0.001). Conclusions: Higher enhancement settings increased visibility of colorectal lesions.
