虚拟尺度内镜 (VSE) 在切除前准确测量结肠直肠聚体大小 (CPS). VSE图像作为有效的教学工具,大大提高了初学者和中级内镜师的CPS估计准确度.
科学领域:
- 胃肠病学 胃肠病学
- 医疗成像医学成像
- 手术技术 手术技术
背景情况:
- 对结直肠多体大小 (CPS) 的内镜评估对于治疗决策至关重要.
- 目前用于CPS测量的方法可以具有可变的准确性.
- 虚拟尺度内镜 (VSE) 提供了一种新的方法,可以在现场测量多重体大小.
研究的目的:
- 为了评估虚拟尺度内镜 (VSE) 测量结直肠聚大小 (CPS) 的准确性.
- 评估VSE图像在提高内镜师CPS估计准确性的教育效益.
主要方法:
- 研究1:比较VSE测量与切割后样本测量,使用Bland-Altman分析对42个结肠直肠多.
- 研究2:通过使用VSE图像进行讲座前后测试,评估了14名内镜医生 (初学者,中级,专家) 的CPS测量准确性.
主要成果:
- 布兰德-阿尔特曼分析显示,VSE和样本测量之间有足够的一致性 (平均偏差±95%LoA: -0.05±0.21毫米).
- 讲座后的CPS测量准确性在初学者 (59.5%对26.7%) 和中级 (65.2%对44.3%) 显著改善.
结论:
- 虚拟尺度内镜 (VSE) 在切除前提供准确的结肠直肠息肉大小测量.
- VSE图像是有价值的教育工具,可以提高CPS估计的准确性,特别是对于经验较少的内镜师来说.
