Endoscopic Procedures II: Colonoscopy

41
The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

概括

血小板数量低的患者 (<90,000/μL) 面临更高的血栓切除术后出血的风险. 维持足够的血小板水平对于安全的结肠镜多斑切除术至关重要,特别是在高风险的手术中.

  • 血液学 血液学 血液学
  • 内視鏡外科手術 內視鏡外科手術

背景情况:

  • 血小板缺血和多细胞切除术后出血 (PPB) 之间的关联还没有得到很好的定义.
  • 目前对进行内镜手术的血小板缺血患者的管理指南是不够的.
  • 这项研究旨在澄清低血小板数量与PPB风险之间的关系.

研究的目的:

  • 评估血小板缺血和多细胞切除术后出血 (PPB) 之间的关联.
  • 为了确定安全的结肠镜多斑切除术所需的血小板数值的最低值.
  • 提供基于证据的建议,用于管理经过多角切除术的血小板缺血患者.

主要方法:

  • 在韩国 (2005-2022) 进行结肠镜检查和多眼镜切除的患者的大型队列研究.
  • 包括各种共同变量:与患者相关的,与聚相关的和与程序相关的因素.
  • 统计分析包括优化切线的Youden指数,倾向性得分匹配和治疗权重的逆概率.

主要成果:

  • 血小板计数<90,000/μL的患者表现出明显更高的立即 (OR 2.67) 和延迟 (OR 9.66) PPB.风险.
  • 100000/μL的血小板计数值被认为是高风险手术的最佳值 (例如,EMR,ESD对于大息肉>20毫米).
  • 在不同的统计分析方法中,研究结果一致.

结论:

  • 血小板缺血 (<90,000/μL) 与立即和延迟PPB的增加率显著相关.
  • 维持血小板数量高于90,000/μL对于确保结肠多斑切除术的安全至关重要.
  • 对于高风险的内镜手术,建议使用更高的100,000/μL值.
