结肠直肠癌的结肠支架的辐射暴露与其他手术相比较. 这支持将结肠支架纳入英国诊断参考水平.
科学领域:
- 胃肠病学 胃肠病学
- 在瘤学瘤学.
- 放射学 放射学是一门学科.
背景情况:
- 自扩张的金属支架 (SEMS) 管理结肠阻塞,通常在光学指导下.
- 结肠直肠癌 (CRC) 管理包括支架用于减压或作为通往手术的桥梁.
- 量化来自结肠支架的辐射暴露对于安全性和比较至关重要.
研究的目的:
- 为了量化在阻塞CRC的结肠支架期间的辐射暴露.
- 将这种暴露与已确定的诊断参考水平 (DRL) 进行比较.
- 为了评估手术成功,支架通透性,静脉栓率和并发症.
主要方法:
- 对47名接受CRC结肠支架移植的患者进行了回顾性观察性研究 (2016年3月 - 2021年2月).
- 辐射暴露量用克尔玛面积积积 (KAP) 和光镜时间来测量.
- 从电子病历中提取的数据.
主要成果:
- 进行了52次手术;KAP中位数为1373.7μGy*m2,光镜中位数时间为8.9分钟.
- 在86.5%的病例中,技术和临床成功.
- 并发症:穿孔 (5.8%),支架迁移 (3.9%). 息性支架的通透率为88.9%.
结论:
- 结肠支架时的辐射暴露在可以接受的范围内.
- 暴露程度与其他光学指导的手术相当.
- 支持将结肠支架纳入英国国家DRL.
