BACKGROUND AND AIM
Olympus Corporation released the texture and color enhancement imaging (TXI) technology as a novel image-enhancing endoscopic technique. We investigated the effectiveness of TXI in the imaging of serrated colorectal polyps, including sessile serrated lesions (SSLs).
METHODS
Serrated colorectal polyps were observed using white light imaging (WLI), TXI, narrow-band imaging (NBI), and chromoendoscopy with and without magnification. Serrated polyps were histologically confirmed. TXI was compared with WLI, NBI, and chromoendoscopy for the visibility of the lesions without magnification and for that of the vessel and surface patterns with magnification. Three expert endoscopists evaluated the visibility scores, which were classified from 1 to 4.
RESULTS
Twenty-nine consecutive serrated polyps were evaluated. In the visibility score without magnification, TXI was significantly superior to WLI but inferior to chromoendoscopy in the imaging of serrated polyps and the sub-analysis of SSLs. In the visibility score for vessel patterns with magnification, TXI was significantly superior to WLI and chromoendoscopy in the imaging of serrated polyps and the sub-analysis of SSLs. In the visibility score for surface patterns with magnification, TXI was significantly superior to WLI but inferior to NBI in serrated polyps and in the sub-analysis of SSLs and hyperplastic polyps.
CONCLUSIONS
TXI provided higher visibility than did WLI for serrated, colorectal polyps, including SSLs.
背景与目的
奥林巴斯公司推出了纹理与色彩增强成像（TXI）技术，作为一种新型的内镜图像增强技术。我们研究了TXI在锯齿状结直肠息肉成像中的有效性，包括无蒂锯齿状病变（SSLs）。
方法
使用白光成像（WLI）、TXI、窄带成像（NBI）以及有无放大功能的染色内镜观察锯齿状结直肠息肉。通过组织学检查确诊锯齿状息肉。将TXI与WLI、NBI和染色内镜在无放大功能时对病变的可视性以及有放大功能时对血管和表面形态的可视性进行比较。三位内镜专家评估可视性评分，评分范围为1至4分。
结果
共评估了29个连续的锯齿状息肉。在无放大功能的可视性评分中，TXI在锯齿状息肉成像及SSLs的亚组分析中显著优于WLI，但不如染色内镜。在有放大功能的血管形态可视性评分中，TXI在锯齿状息肉成像及SSLs的亚组分析中显著优于WLI和染色内镜。在有放大功能的表面形态可视性评分中，TXI在锯齿状息肉以及SSLs和增生性息肉的亚组分析中显著优于WLI，但不如NBI。
结论
对于包括SSLs在内的锯齿状结直肠息肉，TXI比WLI具有更高的可视性。
