Abstract
Background: Recently, Olympus Corporation released new scopes (XZ1200/EZ1500). However, there have been few reports on this topic, although improvement in adenoma detection rate (ADR) by texture and color enhancement imaging (TXI) or computer-aided detection system (CAD) has been reported.
Aim: To investigate the effects of the scope on the detection of adenomas and sessile serrated lesions (SSLs).
Methods: The subjects were patients who underwent pancolonic chromoendoscopy using the EVIS X1 video system center between May 2023 and October 2024. The patients were divided into the new (CF-XZ1200/CF-EZ1500) and 290 series (CF-HQ290Z/PCF-H290Z) groups. Propensity score matching was performed for age, sex, examination purpose, endoscopist, preparation, TXI use, and CAD use. The effects of the scope were analyzed in terms of the ADR, SSL detection rate (SDR), and mean number of adenomas per colonoscopy (APC).
Results: Of the 7014 patients enrolled, 2138 pairs were extracted by propensity score matching (mean age 55.4 years, 45.5% male). The new scopes group had a significantly higher ADR than the 290 series group [51.5% vs 45.5%, odds ratio (OR) = 1.27, 95%CI: 1.13-1.43, P < 0.001]. Similarly, the new scopes group had significantly higher SDR (7.8% vs 5.7%, OR = 1.41, 95%CI: 1.11-1.80, P = 0.005) and APC (0.90 vs 0.76, OR = 1.11, 95%CI: 1.05-1.17, P < 0.001) than the 290 series group.
Conclusion: In conclusion, the new scope (CF-XZ1200/CF-EZ1500) enhanced the detection of adenomas and SSLs compared to the old ones (290 series).
背景：最近，奥林巴斯公司发布了新的瞄准镜（XZ1200/EZ1500）。然而，尽管有报道称通过纹理和彩色增强成像（TXI）或计算机辅助检测系统（CAD）可以提高腺瘤的检出率（ADR），但关于这一主题的报道很少。目的：探讨内镜对腺瘤和无根锯齿状病变（sls）的检查效果。方法：研究对象为2023年5月至2024年10月在EVIS X1视频系统中心行全结肠彩色内镜检查的患者。患者分为新组（CF-XZ1200/CF-EZ1500）和290组（CF-HQ290Z/PCF-H290Z）。对年龄、性别、检查目的、内镜医师、准备、TXI使用和CAD使用进行倾向评分匹配。从不良反应（ADR）、SSL检出率（SDR）和平均每次结肠镜检查腺瘤数（APC）三个方面分析内镜的作用。结果：在7014例入组患者中，通过倾向评分匹配提取了2138对（平均年龄55.4岁，45.5%为男性）。新镜架组的不良反应明显高于290系列组[51.5% vs 45.5%，比值比(OR) = 1.27, 95%CI: 1.13 ~ 1.43, P < 0.001]。同样，新镜架组的SDR （7.8% vs 5.7%, OR = 1.41, 95%CI: 1.11-1.80, P = 0.005）和APC （0.90 vs 0.76, OR = 1.11, 95%CI: 1.05-1.17, P < 0.001）显著高于290系列组。结论：新镜检器（CF-XZ1200/CF-EZ1500）较旧镜检器（290系列）提高了腺瘤和SSLs的检出率。
