Texture and color enhancement imaging (TXI) is a new image-enhanced endoscopy that augments subtle tissue differences and color changes in gastric mucosa. This study aimed to compare the usefulness of TXI and white light imaging (WLI) for diagnosing gastritis. We retrospectively prepared one image set with 22 endoscopic images acquired by WLI and TXI from 60 consecutive patients individually. Five endoscopists independently reviewed the randomly displayed image sets and assessed the infection status on endoscopy according to the Kyoto Classification of Gastritis. The primary endpoints were the accuracies of WLI and TXI in diagnosing -active gastritis. The correlation of the endoscopic features with the three infection statuses (current infection, past infection, and noninfection) was also evaluated. Diagnostic accuracy for active gastritis was significantly higher in TXI than in WLI (85.3 % vs. 78.7 %; = 0.034). All the specific endoscopic features associated with infection statuses had a higher odds ratio with TXI than with WLI. Additionally, interobserver agreement among the five reviewers was higher in TXI than in WLI, except for one pair. TXI may improve the endoscopic diagnosis accuracy for infection.
纹理与颜色增强成像（TXI）是一种新型的图像增强内镜技术，可增强胃黏膜细微的组织差异和颜色变化。本研究旨在比较TXI和白光成像（WLI）在诊断胃炎方面的效用。我们回顾性地准备了一组图像，其中包含从60例连续患者中分别通过WLI和TXI获取的22张内镜图像。五名内镜医师独立审查随机展示的图像集，并根据胃炎的京都分类法评估内镜检查时的感染状况。主要终点是WLI和TXI诊断活动性胃炎的准确性。还评估了内镜特征与三种感染状况（当前感染、既往感染和未感染）之间的相关性。TXI诊断活动性胃炎的准确性显著高于WLI（85.3%对78.7%；P = 0.034）。与感染状况相关的所有特定内镜特征，TXI的优势比均高于WLI。此外，除了一对审查者外，TXI的观察者间一致性高于WLI。TXI可能会提高感染的内镜诊断准确性。
