The usefulness of virtual chromoendoscopy (VC) in capsule endoscopy (CE) isa controversial issue, with conflicting studies regarding its efficacy. FICE and a blue filter were embedded in the PillCam software, with the aim to assist readers in identifying the source of obscure gastrointestinal (GI) bleeding (OGIB), coeliac disease mucosal changes and other small and large bowel lesions, including polyps and tumors. This review aims to summarize the existing evidence on the value of VC in the visualization and identification of different types of pathology. Overall, VC in CE with FICE 1 and 2 can be a useful adjunctive tool and may increase the visibility of pigmented lesions, such as angiectasias and ulcers. However, it does not appear to improve the detection of polyps or tumors. On the other hand, the role of FICE 3 and the blue filter appears to be limited. FICE may also be helpful in differentiating hyperplastic and adenomatous colonic polyps during colon capsule endoscopy, although more evidence is needed.
虚拟染色内镜检查（VC）在胶囊内镜检查（CE）中的作用是一个存在争议的问题，关于其疗效的研究结果相互矛盾。FICE和蓝色滤光片被嵌入到PillCam软件中，旨在帮助读者识别不明原因的胃肠道（GI）出血（OGIB）的来源、乳糜泻的黏膜变化以及其他大肠和小肠病变，包括息肉和肿瘤。这篇综述旨在总结关于VC在可视化和识别不同类型病变方面价值的现有证据。总体而言，在CE中使用FICE 1和2进行VC可以成为一种有用的辅助工具，并且可能会增加色素沉着病变（如血管扩张和溃疡）的可见性。然而，它似乎并不能提高息肉或肿瘤的检测率。另一方面，FICE 3和蓝色滤光片的作用似乎有限。在结肠胶囊内镜检查期间，FICE可能也有助于鉴别增生性和腺瘤性结肠息肉，不过还需要更多证据。
