A new LED endoscopy system featuring advanced noise-reduction technology, the EP-8000 with the EC-860ZP colonoscope (Fujifilm), was introduced in 2024. We evaluated the improvements in colonoscopic image quality of this system, comparing it with a previous system/scope (VP-7000/EC-760ZP). This is a multicenter, observational study. From January 2024 to February 2025, 150 patients undergoing colonoscopy at two institutions were enrolled. Images of the cecum and lesions were captured using white light imaging (WLI), blue light imaging (BLI), and linked color imaging (LCI) under similar conditions. Participants were divided into three groups: Group 1 (EP-8000+EC-860ZP; 50 cases), Group 2 (EP-8000+EC-760ZP; 50 cases), and Group 3 (VP-7000+EC-760ZP; 50 cases). Cecal and lesion images were evaluated for brightness, halation, and visibility using a four-point scale (1 = poor to 4 = excellent) by endoscopists and original values by image-analysis software. In cecal images, the endoscopists' scores in Group 1 were significantly better than in Group 3 for brightness (WLI: 3.71 ± 0.55 vs. 3.51 ± 0.58, < 0.001, BLI: 3.15 ± 0.85 vs. 2.23 ± 0.92, < 0.001; LCI: 3.83 ± 0.42 vs. 3.54 ± 0.58, < 0.001) and for halation (WLI: 3.60 ± 0.51 vs. 3.18 ± 0.59, < 0.001, BLI: 2.99 ± 0.69 vs. 2.71 ± 0.78, < 0.001; LCI: 3.33 ± 0.60 vs. 3.10 ± 0.58, < 0.001). Software analysis confirmed that Group 1 had superior brightness values compared with Group 3 for WLI, BLI, and LCI, as well as lower halation values for WLI and LCI. Regarding lesion images, brightness, halation, and visibility for WLI, BLI, and LCI were superior in Group 1 than in Group 3. The new LED system provided improvements in brightness, halation, and lesion visibility.
2024年推出了一款采用先进降噪技术的新型LED内镜系统，即配备EC - 860ZP结肠镜（富士胶片公司）的EP - 8000。我们评估了该系统结肠镜图像质量的改善情况，并将其与之前的系统/内镜（VP - 7000/EC - 760ZP）进行比较。这是一项多中心观察性研究。2024年1月至2025年2月，两所机构的150例接受结肠镜检查的患者被纳入研究。在相似条件下，使用白光成像（WLI）、蓝光成像（BLI）和联动成像（LCI）采集盲肠和病变的图像。参与者分为三组：第1组（EP - 8000 + EC - 860ZP；50例）、第2组（EP - 8000 + EC - 760ZP；50例）和第3组（VP - 7000 + EC - 760ZP；50例）。内镜医师使用四点量表（1 = 差至4 = 优）对盲肠和病变图像的亮度、光晕和可视性进行评估，图像分析软件记录原始值。在盲肠图像中，第1组内镜医师对亮度的评分（WLI：3.71±0.55 vs. 3.51±0.58，<0.001；BLI：3.15±0.85 vs. 2.23±0.92，<0.001；LCI：3.83±0.42 vs. 3.54±0.58，<0.001）和光晕评分（WLI：3.60±0.51 vs. 3.18±0.59，<0.001；BLI：2.99±0.69 vs. 2.71±0.78，<0.001；LCI：3.33±0.60 vs. 3.10±0.58，<0.001）均显著优于第3组。软件分析证实，第1组在WLI、BLI和LCI方面的亮度值优于第3组，在WLI和LCI方面的光晕值更低。对于病变图像，第1组在WLI、BLI和LCI的亮度、光晕和可视性方面均优于第3组。这款新型LED系统在亮度、光晕和病变可视性方面有了改善。
