2020年，奥林巴斯医疗系统公司推出了纹理和颜色增强成像（TXI）作为一种新的图像增强内窥镜。本研究旨在通过TXI评价上消化道肿瘤和粘膜萎缩的可见性。我们分别对12例胃肿瘤和20例胃萎缩/非萎缩粘膜的72和60张图像进行了评价。由6名内镜医师使用先前报告的可见性量表（1 =差至4 =优）评估胃粘膜萎缩和胃肿瘤的可见性。采用国际照明委员会L*a*B* 颜色空间系统评估胃粘膜萎缩和非萎缩粘膜之间以及胃肿瘤和邻近区域之间的颜色差异。与白光成像（WLI）相比，TXI模式1中粘膜萎缩和胃肿瘤的可见性显著改善（粘膜萎缩的可见性评分：3.8 ± 0.5 vs. 2.8 ± 0.9，p < 0.01;胃肿瘤的可见性评分：2.8 ± 1.0 vs. 2.0 ± 0.9，p < 0.01）。对于胃萎缩和非萎缩粘膜，TXI模式1的色差显著大于WLI（色差：分别为14.2 ± 8.0 vs. 8.7 ± 4.2，p < 0.01）。TXI可能是上消化道内镜筛查的一种有用的观察方式。
In 2020, Olympus Medical Systems Corporation introduced the Texture and Color Enhancement Imaging (TXI) as a new image-enhanced endoscopy. This study aimed to evaluate the visibility of neoplasms and mucosal atrophy in the upper gastrointestinal tract through TXI. We evaluated 72 and 60 images of 12 gastric neoplasms and 20 gastric atrophic/nonatrophic mucosa, respectively. The visibility of gastric mucosal atrophy and gastric neoplasm was assessed by six endoscopists using a previously reported visibility scale (1 = poor to 4 = excellent). Color differences between gastric mucosal atrophy and nonatrophic mucosa and between gastric neoplasm and adjacent areas were assessed using the International Commission on Illumination L*a*b* color space system. The visibility of mucosal atrophy and gastric neoplasm was significantly improved in TXI mode 1 compared with that in white-light imaging (WLI) (visibility score: 3.8 ± 0.5 vs. 2.8 ± 0.9, p < 0.01 for mucosal atrophy; visibility score: 2.8 ± 1.0 vs. 2.0 ± 0.9, p < 0.01 for gastric neoplasm). Regarding gastric atrophic and nonatrophic mucosae, TXI mode 1 had a significantly greater color difference than WLI (color differences: 14.2 ± 8.0 vs. 8.7 ± 4.2, respectively, p < 0.01). TXI may be a useful observation modality in the endoscopic screening of the upper gastrointestinal tract.
