AIM
To validate high definition endoscopes with Fujinon intelligent chromoendoscopy (FICE) in colonoscopy.
METHODS
The image quality of normal white light endoscopy (WLE), that of the 10 available FICE filters and that of a gold standard (0.2% indigo carmine dye) were compared.
RESULTS
FICE-filter 4 [red, green, and blue (RGB) wavelengths of 520, 500, and 405 nm, respectively] provided the best images for evaluating the vascular pattern compared to white light. The mucosal surface was best assessed using filter 4. However, the views obtained were not rated significantly better than those observed with white light. The "gold standard", indigo carmine (IC) dye, was found to be superior to both white light and filter 4. Filter 6 (RGB wavelengths of 580, 520, and 460 nm, respectively) allowed for exploration of the IC-stained mucosa. When assessing mucosal polyps, both FICE with magnification, and magnification following dye spraying were superior to the same techniques without magnification and to white light imaging. In the presence of suboptimal bowel preparation, observation with the FICE mode was possible, and endoscopists considered it to be superior to observation with white light.
CONCLUSION
FICE-filter 4 with magnification improves the image quality of the colonic vascular patterns obtained with WLE.
目的
验证富士能高清智能 chromoendoscopy（FICE）在结肠镜检查中的应用。
方法
比较了正常白光内镜（WLE）、10 种可用的 FICE 滤光片和金标准（0.2%靛胭脂染料）的图像质量。
结果
与白光相比，FICE 滤光片 4（红、绿、蓝的波长分别为 520、500 和 405nm）在评估血管模式方面提供了最佳图像。使用滤光片 4 可以最佳地评估黏膜表面。然而，与白光观察相比，所获得的视野并没有得到显著改善。靛胭脂（IC）染料被发现优于白光和滤光片 4。滤光片 6（红、绿、蓝的波长分别为 580、520 和 460nm）允许探索 IC 染色的黏膜。在评估黏膜息肉时，FICE 放大和染色后放大都优于无放大和白光成像的相同技术。在肠道准备不佳的情况下，仍可以进行 FICE 模式观察，并且内镜医生认为其优于白光观察。
结论
FICE 滤光片 4 与放大功能可提高 WLE 获得的结肠血管模式的图像质量。
