使用5色发光二极管（LED）（EVIS X1; Olympus Co.，东京，日本），其中包括纹理和色彩增强成像（TXI），已经发布。在这项研究中，我们分析了TXI对非息肉样结直肠病变的可见性及其诊断准确性的影响。我们回顾了26例患者的101个非息肉样病变，这些病变通过白色光成像（WLI）、窄带成像（NBI）和TXI观察。由6名内窥镜医师使用息肉可见性评分（4（优）至1（差））评价每种模式的一张代表性图像。我们计算了三种模式下每个病变的色差（CD）值。对于肿瘤特征，由3名专家根据NBI分类评价TXI和NBI放大的一个代表性图像。TXI的息肉可见性评分的最小二乘均值[95%置信区间]（3.42 [3.06-3.77]）显著高于WLI（2.85 [2.49-3.20]，p < 0.001），但NBI（3.33 [2.98-3.69]，p = 0.258）则无显著差异。TXI的CD值（13.3 ± 6.3）高于WLI（9.7 ± 6.0，p < 0.001），但不高于NBI（13.1 ± 6.8，p = 0.81）。对于无蒂锯齿状病变，TXI的CD值（11.1 ± 4.4）倾向于低于NBI的CD值（12.6 ± 6.0，p = 0.07）。NBI的诊断准确性和放大率置信水平明显优于TXI（分别为87.1 vs. 80.5%，p = 0.027，87.5 vs. 62.7%，p < 0.001）。TXI在内镜医师评分和CD值方面显示出比WLI更好的可见性，并且可以提高息肉检测。
An endoscopic system using 5-color light-emitting diodes (LEDs) (EVIS X1; Olympus Co., Tokyo, Japan), which includes texture and color enhancement imaging (TXI), has been released. In this study, we analyzed the effects of TXI on the visibility of non-polypoid colorectal lesions and its diagnostic accuracy. We reviewed 101 non-polypoid lesions from 26 patients observed with white light imaging (WLI), narrow band imaging (NBI), and TXI. One representative image of each mode was evaluated by 6 endoscopists using a polyp visibility score of 4 (excellent) to 1 (poor). We calculated the color difference (CD) values for each lesion in the three modes. For tumor characteristics, one representative image of TXI and NBI magnification was evaluated by 3 experts according to a NBI classification. The least squares means [95% confidence interval] of polyp visibility score of TXI (3.42 [3.06–3.77]) was significantly higher than that of WLI (2.85 [2.49–3.20], p < 0.001) but not that of NBI (3.33 [2.98–3.69], p = 0.258). The CD value of TXI (13.3 ± 6.3) was higher than that of WLI (9.7 ± 6.0, p < 0.001) but not that of NBI (13.1 ± 6.8, p = 0.81). For sessile serrated lesions, the CD value of TXI (11.1 ± 4.4) tended to be lower than that of NBI (12.6 ± 6.0, p = 0.07). The diagnostic accuracy and confidence level of magnification for NBI were significantly better than those for TXI (87.1 vs. 80.5%, p = 0.027, 87.5 vs. 62.7%, p < 0.001, respectively). TXI showed better visibility than WLI in terms of the endoscopist’s score and CD value and may improve polyp detection.
