摘要:
目的:研究老年病人胰十二指肠切除术(pancreaticoduodenectomy, PD)术后严重并发症发生的危险因素。方法:回顾性分析2016年1月至2020年12月本院行PD 399例≥65岁(65~91岁)老年病人的临床资料,其中≥75岁76例(19.0%)。Barthel指数低提示生活自理能力低下。用二元Logistic回归分析PD术后严重并发症的危险因素,构建预测模型。以受试者工作特征(ROC)曲线验证模型的预测效能。结果:399例老年PD病人中,术后并发症发生224例,总发生率56.14%。轻度并发症187例(46.87%),严重并发症37例(9.27%)。年龄≥75岁(OR=2.78, P<0.05)、合并高血压(OR=4.20, P<0.05)和Barthel指数(提示生活自理能力)低(OR=0.96, P<0.05)为老年PD术后严重并发症发生的独立危险因素。以年龄、合并高血压、术前营养风险、手术形式、生活自理能力的Barthel指数、手术时间6项指标构建PD术后严重并发症的风险模型,回归方程拟合度0.93。ROC曲线显示,该模型曲线下面积AUC为0.76,灵敏度65%,特异度76%。结论:年龄≥75岁、合并高血压且生活自理能力低为老年病人PD术后严重并发症的独立性危险因素。以年龄等6项指标构建的模型能较好预测老年病人PD术后严重并发症的发生。
