2、于贵州医科大学附属医院行直肠癌 Dixon 手术的260 例患者，根据术后吻合口漏发生情况分为吻合口漏组与无吻合口漏组。收集患者临床资料，术后评估两组 CLS 评分，术后第1、3 d 检测中性粒细胞、淋巴细胞计数、C 反应蛋白和白蛋白，计算 NLR、CAR；采用 Logistics 回归分析术后吻合口漏的影响因素，采用受试者工作特征（ROC）曲线分析 CLS、NLR、CAR 对吻合口漏的预测价值。结果：260 例患者术后发生 20 例吻合口漏，发生率为 7.69%。吻合口漏组 CLS 评分高于无吻合口漏组（P0.05）；术后第 1 d 两组 NLR、CAR 比较差异无统计学意义（P0.05），
3、术后第 3 d 吻合口漏组 NLR、CAR 高于无吻合口漏组（P0.05）。两组吻合口至肛缘距离、糖尿病史、术前低蛋白血症、术前肠梗阻占比比较差异有统计学意义（P0.05）。多因素 Logistics 回归分析显示，吻合口距肛缘距离、糖尿病史、术前低蛋白血症、术前肠梗阻、CLS、NLR、CAR 是患者术后发生吻合口漏的影响因素（P0.05）。ROC 曲线分析显示，CLS 的曲线下面积（AUC）为 0.851，NLR 的 AUC 为 0.861，CAR 的 AUC 为 0.859，三者联合的 AUC 为 0.945，高于单独检测。结论：Dixon 术后发生吻合口漏患者CLS 评分、NLR 和 C
4、AR 升高，CLS 评分联合 NLR、CAR 可有效预测直肠癌 Dixon 术后吻合口漏发生风险，可作为评估吻合口漏的辅助指标，以降低术后吻合口漏的发生率。关键词：直肠癌；Dixon 手术；结直肠漏评分；NLR；CAR；吻合口漏；预测价值中图分类号：R735.37文献标识码：A文章编号：1673-6273（2023）02-340-05Value Study of Colorectal Leakage Score Combined with Neutrophil toLymphocyte Ratio and C-Reactive Protein to Albumin Ratio in Predi

16、）术为常用手术3，疗效得到临床认可，但术后易发生吻合口漏，且大多发生在术后 57 d，严重影响患者术后恢复，延长住院时间，增加其医疗负担，甚至威胁生命4,5。故寻找相关指标预测术后吻合口漏发生风险成为了临床研究重点。结直肠漏评分（CLS）是由国外学者提出的针对左半结直肠癌切除术后评估吻合口漏的指标6，近年来国内临床将其应用于左侧结直肠切除术后吻合口漏的评估7。中性粒细胞与淋巴细胞比值（NLR）不仅反映了炎症程度，还被证实与肿瘤预后有关8，可预测结直肠癌患者预后9，但 NLR 能否用于预测直肠癌术后吻合口漏尚不明确。C 反应蛋白与白蛋白比值（CAR）最初被作为创伤后预警指标，随着研究进展，发现 CAR可预测结直肠癌患者预后10,11。因此，本研究分析 Dixon 术后发生吻合口漏的影响因素，探究 CLS 评分联合 NLR、CAR 对吻合口漏的预测价值，旨在寻找相关指标评估和预测术后吻合口漏发生风险。1 资料与方法1.1 一般资料选取 2020 年 4 月-2022 年 3 月于贵州医科大学附属医院行直肠癌 Dixon 手术的 260 例患者，其中男 153 例，女 107 例；年龄为 2
