科学领域:

  • 腹部外科 腹部外科
  • 胃肠病学 胃肠病学
  • 医疗信息学 医疗信息学

背景情况:

  • 由于并发症或并发症,在内镜袖胃整形术 (ESG) 后有时需要重新干预.
  • 需要一个经过验证的工具来预测ESG后早期重新干预的风险.

研究的目的:

  • 开发和验证一个内镜袖胃形成术再干预得分 (ESG-RS) 以预测30天的再干预风险.
  • 确定ESG后重新干预的关键预测因素.

主要方法:

  • 从质量改进数据库中利用了3583名接受ESG (2016-2021) 的患者的数据.
  • 采用LASSO回归来选择预测因素,然后进行多变量分析来创建ESG-RS.
  • 使用十倍交叉验证和接收器-运营商曲线评估模型性能.

主要成果:

  • 确定了ESG-RS的5个关键预测因素:前前肠外科手术,手术前的抗凝剂,女性性别,ASA类≥II和高血压.
  • ESG-RS表现出良好的预测能力,曲线下的面积为0.74.
  • 确定了67.9的最佳切割点,区分高风险和低风险患者,敏感度为76%和特异性为71%.

结论:

  • 开发的ESG-RS为接受ESG的患者进行手术前风险分层提供了有价值的工具.
  • 临床医生可以使用ESG-RS来识别患有早期重新干预风险较高的患者,从而实现主动管理.
