  • 摘要:   目的  探讨甘油三酯-葡萄糖指数(TyG)及甘油三酯-葡萄糖-体重指数(TyG-BMI)与胰体尾切除术(DP)后新发糖尿病(NODM)的关系,并评价其临床应用价值。  方法  回顾性收集2020年1月—2024年12月于新疆医科大学第一附属医院接受DP且术前无糖尿病的161例患者资料。根据术后是否发生NODM将其分为NODM组(n=43)与非NODM组(n=118),比较其基线临床资料。采用多因素Logistic回归分析TyG及TyG-BMI与NODM的关系,并通过限制性立方样条模型分析TyG及TyG-BMI与NODM风险的剂量-反应关系。采用受试者操作特征曲线(ROC曲线)评估TyG及TyG-BMI对NODM的预测效能。  结果  161例患者中,术后NODM发生率为26.7%(43/161)。NODM组患者的TyG[(8.89±0.57) vs (8.54±0.56),P<0.001]及TyG-BMI[232.18(195.31~249.68) vs 195.39(178.92~221.38),P<0.001]均显著高于非NODM组。多因素Logistic回归分析结果显示,在调整年龄、性别及糖化血红蛋白后,TyG[比值比(OR)=2.78,95%置信区间(CI):1.43~5.39,P=0.003)及TyG-BMI(OR=1.02,95%CI:1.01~1.04,P<0.001)仍为DP术后NODM发生的独立危险因素。限制性立方样条分析提示,TyG及TyG-BMI与NODM发生风险均呈近似线性正相关。ROC曲线分析表明,TyG与TyG-BMI预测DP术后NODM的曲线下面积分别为0.725(95%CI:0.683~0.867)和0.719(95%CI:0.610~0.810),表现出中等的预测价值。  结论  TyG与TyG-BMI是DP术后发生NODM的独立预测因子,二者对NODM的诊断具有一定的预测效能。提示这两种简便的代谢指标有望成为临床早期识别DP术后NODM高危人群的辅助工具。
