高清晰度 (HD) 白光内镜与分段再检查同HD染色内镜在检测炎症性肠病 (IBD) 患者的结直肠瘤一样有效. 更长的检查时间,而不仅仅是增强的对比度,可能解释了染色内镜的好处.
科学领域:
- 胃肠病学 胃肠病学
- 内镜检查是指内镜检查.
- 结肠直肠癌查 结肠直肠癌查
背景情况:
- 在炎症性肠病 (IBD) 患者中使用高清 (HD) 染色内镜与HD白光内镜对结肠直肠新生病的优异检测受到争议.
- 目前尚不清楚增强的对比度或延长的检查时间是否更有助于染色内镜的有效性.
研究的目的:
- 为了比较HD白光内镜与细分再检查和HD染色内镜之间的结肠直肠瘤检测率.
- 为了评估单通高清白光内镜作为额外的控制.
主要方法:
- 一项多中心随机对照试验包括年龄≥18岁且没有活跃疾病的IBD患者,接受内镜监测.
- 患者被随机分配到HD白光内镜与细分重新检查 (双通道),HD染色内镜或单通道HD白光内镜.
- 主要结局是结直肠瘤检测率.
主要成果:
- HD白光内镜与细分再检查表明不低于HD染色内镜 (10.3%对13.1%;p<0.01).
- 在这两种方法中,每分钟停药时间的检测率在两种方法之间是相似的 (0.062 vs 0.058; p=0.83).
- 与分段再检查相比,单通高清白光内镜检测率 (6.1%) 较低,但在统计上并不显著.
结论:
- 在IBD患者中检测结直肠瘤时,HD白光内镜与细分再检查是HD染色内镜的可行替代方案.
- 这些发现表明,延长抽取时间,而不是仅仅增强对比度,有助于染色内镜的疗效.
- 单独的细分重新检查并没有显著增加瘤检测,而不是单通HD白光内镜.
