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 Lab* 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.
2020 年,奥林巴斯医疗系统公司推出了纹理和色彩增强成像(TXI)作为一种新的图像增强内镜。本研究旨在通过 TXI 评估上消化道肿瘤和黏膜萎缩的可见性。我们分别评估了 12 个胃肿瘤的 72 个和 20 个胃萎缩/非萎缩黏膜的 60 个图像。六位内镜医生使用之前报道的可视性评分(1=差到 4=优秀)评估胃黏膜萎缩和胃肿瘤的可视性。使用国际照明委员会 Lab*颜色空间系统评估胃黏膜萎缩和非萎缩黏膜以及胃肿瘤和相邻区域之间的颜色差异。与白光成像(WLI)相比,TXI 模式 1 显著提高了黏膜萎缩和胃肿瘤的可视性(可视性评分:3.8±0.5 对 2.8±0.9,p<0.01;可视性评分:2.8±1.0 对 2.0±0.9,p<0.01)。对于胃萎缩和非萎缩黏膜,TXI 模式 1 与 WLI 相比具有显著更大的颜色差异(颜色差异:14.2±8.0 对 8.7±4.2,均 p<0.01)。TXI 可能是上消化道内镜筛查的有用观察方式。
