线性内镜超声波 (EUS) 和窄带成像 (NBI) 在分期直肠病变侵袭深度方面提供了相似的准确性. 建议使用单个NBI,因为它在临床实践中的简单性和便利性.
科学领域:
- 胃肠病学 胃肠病学
- 内镜检查是指内镜检查.
- 在瘤学瘤学.
背景情况:
- 线性阵列内镜超声波 (EUS) 和窄带成像 (NBI) 是评估非踏脚直肠病变 (NPRL) 侵袭深度的诊断工具.
- 对于NPRLs,EUS和NBI的比较诊断准确性仍然不清楚.
研究的目的:
- 为了比较线性EUS和NBI的诊断准确度,以估计非脚踏直肠病变 (NPRLs) 的入侵深度.
主要方法:
- 进行了一项单中心,随机,并联试验.
- 患者被分配到EUS,其次是NBI (A组) 或NBI,其次是EUS (B组).
- 侵袭深度被分为粘膜层到轻微的粘膜层 (<1,000微米) 或深的粘膜层 (≥1,000微米),术后病理是黄金标准.
主要成果:
- 在EUS (96.2%) 和NBI (93.7%) 之间发现了可比的诊断准确度.
- 对于深部粘膜下侵袭,EUS的敏感性 (81.8%) 比NBI (63.6%) 高,但特异性相似 (98.5%).
- 程序时间和EUS和NBI的联合使用并没有显著提高诊断准确性.
结论:
- 线性EUS和NBI在测量NPRL入侵深度方面表现出可比的准确性.
- 结合EUS和NBI并不能提高诊断的准确性.
- 由于其临床简单性和方便性,单个NBI是首选的.
