Abstract

Background: A compact and cost-effective light source-processor combined 3-color light-emitting diode (LED) endoscopic system (ELUXEO-Lite: EP-6000, Fujifilm Co., Tokyo) with a magnified colonoscope (EC-6600ZP, Fujifilm Co.) has been released. Aims: In this study, we analyzed the efficacy of this system for colorectal tumor characterization with magnified blue light imaging (BLI-LED) and image's subjective and objective evaluations, compared to a magnified blue laser imaging (BLI-LASER) using a standard LASER endoscopic system. Methods: We retrospectively reviewed 37 lesions observed with both BLI-LED and BLI-LASER systems from 2019 using the Japanese narrow band imaging classification. Two representative magnified images, one BLI-LED and one BLI-LASER, of the same area of a lesion were evaluated for diagnostic accuracy and visualization quality by three experts and three non-experts. Their color difference values (CDVs) and brightness values (BVs) were also calculated as objective indicators. Results: Among 37 lesions, mean tumor size was 18.9 ± 13.1 mm, and 21 lesions were nonpolypoid. Histopathology revealed 14 sessile serrated lesions, 7 adenomas, 12 high-grade dysplasias and T1a cancers, and 4 T1b cancers. The diagnostic accuracy rates of BLI-LED/BLI-LASER of experts and non-experts were 90.1% and 87.4% (p = 0.52) and 89.2% and 89.2% (p = 0.99). The percentages of instances where BLI-LED images were better, the two imaging types were equivalent, or BLI-LASER images were better were 16%/83%/1% for experts and 19%/58%/23% for non-experts (p < 0.001). CDVs and BVs between BLI-LED and BLI-LASER were not significantly different (CDVs: p = 0.653, BVs: p = 0.518). Conclusions: BLI-LED using the compact system was noninferior to BLI-LASER for colorectal tumor characterization and image quality.
与激光内镜系统相比,紧凑发光二极管内镜系统蓝光成像对结直肠病变肿瘤特征的有效性:一项试点研究
背景:一款紧凑且具有成本效益的光源处理器组合三色发光二极管(LED)内窥镜系统(ELUXEO-Lite: EP-6000,富士胶片公司,东京)与放大结肠镜(EC-6600ZP,富士胶片公司)已经发布。目的:在本研究中,我们分析了该系统在使用放大蓝光成像(BLI-LED)进行结直肠肿瘤表征的有效性以及图像的主客观评价,并与使用标准激光内镜系统的放大蓝光成像(BLI-LASER)进行比较。方法:回顾性分析2019年以来BLI-LED和BLI-LASER系统观察到的37个病变,采用日本窄带成像分类。由三名专家和三名非专家对病变同一区域的两幅代表性放大图像(一幅BLI-LED和一幅BLI-LASER)的诊断准确性和可视化质量进行评估。并计算其色差值(cdv)和亮度值(bv)作为客观指标。结果:37例病变中,平均肿瘤大小为18.9±13.1 mm,非息肉样病变21例。组织病理学显示14例无梗锯齿状病变,7例腺瘤,12例高度发育不良和T1a癌,4例T1b癌。专家和非专家BLI-LED/BLI-LASER的诊断准确率分别为90.1%和87.4% (p = 0.52)和89.2%和89.2% (p = 0.99)。BLI-LED图像更好、两种成像类型等效或BLI-LASER图像更好的实例百分比在专家中为16%/83%/1%,在非专家中为19%/58%/23% (p < 0.001)。BLI-LED与BLI-LASER的cdv和bv差异无统计学意义(cdv: p = 0.653, bv: p = 0.518)。结论:使用紧凑系统的BLI-LED在结直肠肿瘤特征和图像质量方面优于BLI-LASER。
