科学领域:

  • 肝病学 肝病学是一种肝病学.
  • 移植手术 移植手术
  • 医疗信息学 医疗信息学

背景情况:

  • 胆道并发症 (BCs) 是肝移植后的重大风险,风险因素定义不佳,发病时间可变.
  • 机器学习 (ML) 在分析复杂的医疗数据以预测肝移植方面表现有前途.

研究的目的:

  • 确定ML是否能有效地预测肝移植后的BCs.
  • 在移植后的3,6个月和12个月确定BCs的特定风险因素.

主要方法:

  • 利用来自两个中心的517名患者的数据,随机分为培训和验证集.
  • 在模型验证和解释中采用K折交叉验证,合成少数过量采样技术和SHapley添加式扩平 (SHAP) 值.
  • 开发和评估了7个ML算法,用于在移植后3,6和12个月预测BCs.

主要成果:

  • 支持向量机 (SVM) 证明了BCs的最高预测准确性,AUC值为0.916 (3个月),0.892 (6个月) 和0.885 (12个月).
  • 确定了关键的3个月风险因素:捐赠者的年龄,末期肝病 (MELD) 模型得分,瘤性疾病,糖尿病,高血压和手术内输血.
  • 确定了6个月的风险因素:接受者的年龄,捐赠者和接受者的BMI,以及糖尿病. 12个月的风险因素包括接受者的年龄,糖尿病和巴西利西马布.

结论:

  • 在所有术后期间,ML算法有效地识别了BCs的风险因素.
  • 这些发现为优化患者管理和潜在地减轻肝移植后BCs提供了宝贵的见解.
