结肠镜的起始位置,无论是左侧或其他方法,都不会显著影响内输管时间. 这一系统性审查表明,在结肠镜检查过程中,患者的位置可以灵活地安排.
科学领域:
- 胃肠病学 胃肠病学
- 内镜检查是指内镜检查.
- 临床试验 临床试验
背景情况:
- 传统上,结肠镜检查始于患者在左侧腰位置.
- 最近的研究已经探索了替代的起始位置.
- 这一系统性审查和元分析旨在比较不同的结肠镜检查起始位置及其对腔输管的影响.
研究的目的:
- 为了比较不同患者的起始位置对结肠镜检查的疗效.
- 为了确定不同起始位置对腔输管时间的影响.
- 综合来自RCT关于结肠镜手术结果的证据.
主要方法:
- 在MEDLINE,Embase和CENTRAL数据库中搜索到2023年7月.
- 包括对接受结肠镜检查的成年人至少两种不同的起始位置进行比较的RCT.
- 使用逆方差随机效应模型进行了元分析,以评估腔输管时间.
- 使用RCT的Cochrane工具评估偏差风险 2.0.0.
主要成果:
- 包括14个RCT在选1523个引用后.
- 与左侧部和右侧部进行比较,左侧向下倾斜,倾斜和仰卧位置.
- 在所有比较中都没有发现腔输管时间的统计学上显著差异.
- 报告的高异质性 (I2 > 80%) 在整个比较.
结论:
- 结肠镜检查的起始位置的选择似乎没有影响内输管所需的时间.
- 临床实践可能不需要坚持特定的起始位置以优化输管时间.
- 可能需要进一步的研究来解决包含的研究中观察到的异质性.
