联动成像技术识别早期分化型胃癌的优势：与靛胭脂和蓝光成像的对比
Benefits of linked color imaging for recognition of early differentiated-type gastric cancer: in comparison with indigo carmine contrast method and blue laser imaging
T Yasuda, N Yagi, T Omatsu, S Hayashi, Y Nakahata… - Surgical Endoscopy, 2021
LCI在内镜筛查中比IC和BLI-brt更有利于识别早期分化型胃癌。
Conclusions: LCI appears to be more beneficial for the recognition of early differentiated-type gastric cancer in endoscopic screenings than IC and BLI-brt from the middle to distant view.
01
背景和目标
联动成像技术（LCI）是一种新的内镜系统，可增强黏膜颜色的细微差异。然而，在识别早期胃癌方面，LCI是否可比其他类型的图像增强内镜（IEE）更有用仍不清楚。本研究旨在评估LCI与靛胭脂染色法（IC）和蓝光成像亮度模式（BLI-brt）在早期分化型胃癌识别中的有效性。
Background and aim: Linked color imaging (LCI) is a novel endoscopy system, which enhances slight differences in mucosal color. However, whether LCI is more useful than other kinds of image-enhanced endoscopy (IEE) in recognizing early gastric cancer remains unclear. This study aimed to evaluate LCI efficacy compared with the indigo carmine contrast method (IC), and blue laser imaging-bright (BLI-brt) in early differentiated-type gastric cancer recognition.

方法
我们回顾性分析了2014年6月至2018年11月在朝日大学医院通过所有四种成像技术（白光、IC、LCI、BLI-brt）检查的早期分化型胃癌。主观评价（使用排名分数：RS）和客观评价（使用色差评分：CDS）量化早期分化型胃癌的识别。
Methods: We retrospectively analyzed early differentiated-type gastric cancer, which were examined by all four imaging techniques (white light imaging, IC, LCI, BLI-brt) at Asahi University Hospital from June 2014 to November 2018. Both subjective evaluation (using ranking score: RS) and objective evaluation (using color difference score: CDS) were adopted to quantify early differentiated-type gastric cancer recognition.

结果
在此期间，本研究纳入了87个病灶。LCI的RS和CDS均显著高于IC和BLI-brt（p < 0.01）。BLI-brt的RS和CDS与IC相比无明显差异。亚组分析显示，与IC和BLI-brt相比，LCI在幽门螺杆菌根除后患者和扁平或凹陷病灶中特别有用。
Results: During this period, 87 lesions were enrolled in this study. Both RS and CDS of LCI were significantly higher (p < 0.01) than those of IC and BLI-brt. Both RS and CDS of BLI-brt had no significant difference compared with those of IC. Subgroup analysis revealed that LCI was especially useful in post-Helicobacter pylori eradication patients and flat or depressed lesions compared with IC and BLI-brt.
