背景资料：图像增强的内窥镜检查方法，如窄带成像（NBI）是优于白光成像（WLI）检测胃萎缩，肠化生，和癌症。虽然新的第三代高视觉内窥镜比第二代内窥镜提高了图像质量和分辨率，但尚不清楚前者是否也增强了内窥镜检测萎缩和肠化生周围的色差。我们比较了新的第三代内窥镜和旧的第二代内窥镜的有效性。研究方法：在我们的回顾性研究中，我们入组了50例使用第二代和第三代内窥镜（分别为GIF-290 N和GIF-1200 N）进行经鼻内窥镜检查的幽门螺杆菌根除患者。基于国际照明委员会1976（L*，a*，B*）颜色空间，比较了第二代和第三代高视觉内窥镜之间的色差。结果如下：GIF-1200 N内窥镜上NBI产生的萎缩周围的颜色差异显著大于GIF-290 N（19.2 ± 8.5 vs. 14.4 ± 6.2，p = 0.001）。相比之下，GIF-1200 N和GIF-290 N内窥镜上使用WLI和NBI时肠上皮化生周围的颜色差异相似。NBI在两种内窥镜上检测肠上皮化生方面优于WLI。结论：使用第三代内镜的NBI在H.根除幽门的患者与WLI相比。
Background: Image-enhanced endoscopy methods such as narrow-band imaging (NBI) are advantageous over white-light imaging (WLI) for detecting gastric atrophy, intestinal metaplasia, and cancer. Although new third-generation high-vision ultrathin endoscopes improve image quality and resolution over second-generation endoscopes, it is unclear whether the former also enhances color differences surrounding atrophy and intestinal metaplasia for endoscopic detection. We compared the efficacy of a new third-generation ultrathin endoscope and an older second-generation endoscope. Methods: We enrolled 50 Helicobacter pylori-eradicated patients who underwent transnasal endoscopy with a second-generation and third-generation endoscope (GIF-290N and GIF-1200N, respectively) in our retrospective study. Color differences based on the International Commission on Illumination 1976 (L*, a*, b*) color space were compared between second-generation and third-generation high-vision endoscopes. Results: Color differences surrounding atrophy produced by NBI on the GIF-1200N endoscope were significantly greater than those on GIF-290N (19.2 ± 8.5 vs. 14.4 ± 6.2, p = 0.001). In contrast, color differences surrounding intestinal metaplasia using both WLI and NBI were similar on GIF-1200N and GIF-290N endoscopes. NBI was advantageous over WLI for detecting intestinal metaplasia on both endoscopes. Conclusions: NBI using a third-generation ultrathin endoscope produced significantly greater color differences surrounding atrophy and intestinal metaplasia in H. pylori-eradicated patients compared with WLI.
