There has been remarkable progress to improve the quality of white-light imaging with the introduction of image-enhanced endoscopy (IEE). Texture and color enhancement imaging (TXI) and red dichromatic imaging (RDI) are promising novel IEE techniques. In this report, we provide an overview of these technologies and their clinical applications.
The IEE modes can be activated on the EVIS X1 video processor system (Olympus Corporation, Tokyo, Japan) during the endoscopic procedure. We present cases in which texture and color enhancement and RDI modalities are used in real time.
We demonstrate cases in which these novel IEE modes (1) helped enhance the surface structure of a colonic lesion during optical diagnosis, (2) improved demarcation of the normal mucosa and neoplastic lesion during snare resection of a duodenal polyp, (3) delineated submucosal structures and muscle layer during endoscopic submucosal dissection, and (4) enhanced visualization of blood vessels for prophylactic hemostasis and management of active bleeding during endoscopic resection.
This video review provides a general overview of both TXI and RDI during endoscopic resection of gastrointestinal neoplasia. Future studies are needed to corroborate the current evidence on these IEE modalities and further define their potential applications across various endoscopic procedures.
随着图像增强内镜检查（IEE）的引入，白光成像质量有了显著提高。纹理和颜色增强成像（TXI）以及红色双色成像（RDI）是很有前景的新型IEE技术。在本报告中，我们对这些技术及其临床应用进行了概述。
在内镜检查过程中，可在EVIS X1视频处理器系统（日本东京奥林巴斯公司）上激活IEE模式。我们展示了实时使用纹理和颜色增强以及RDI模式的病例。
我们展示的病例表明，这些新型IEE模式（1）在光学诊断期间有助于增强结肠病变的表面结构，（2）在十二指肠息肉圈套切除术中改善了正常黏膜与肿瘤病变的界限划分，（3）在内镜黏膜下剥离术中勾勒出黏膜下结构和肌层，（4）在内镜切除术中增强了血管可视化，用于预防性止血和处理活动性出血。
本视频综述对胃肠道肿瘤内镜切除术中的TXI和RDI进行了总体概述。需要进一步的研究来证实目前关于这些IEE模式的证据，并进一步明确它们在各种内镜手术中的潜在应用。
