术后吲哚菁绿15min滞留率联合标准残肝体积对肝细胞癌术后肝功能不全的预测价值

摘要

目的:探讨术后第3天吲哚菁绿15 min滞留率(indocyanine green retention rate at 15 minutes,ICG R15)联合标准残肝体积(standard remnant liver volume,SRLV)对肝细胞癌术后肝功能不全的预测价值.方法:回顾性研究中南大学湘雅医院普通外科在2015年1月至2016年2月期间收治的61例肝细胞癌行肝部分切除术患者的临床资料,并将其分为肝功能良好组(n=40)与肝功能不全组(n=21),采用单因素分析筛选术后肝功能不全发生的危险因素,采用回归分析筛选术后肝功能不全的独立危险因素并建立同归方程,采用受试者工作特征(receiver operating characteristics,ROC)曲线分析单一的独立危险因素与联合的独立危险因素在术后肝功能不全诊断上的价值差异.结果:61例手术患者中共有21例发生术后肝功能不全,肝功能不全发生率为34.4％.术后肝功能良好组与肝功能不全组在手术时间、肝门阻断时间、肿瘤体积、切除肝体积方面差异均无统计学意义(均P＞0.05);而在术后ICG R15,术中出血量和SRLV上差异均有统计学意义(均P＜0.05).术后ICG R15,术中出血量和SRLV是术后肝功能不全的危险因素.回归分析提示:术后ICG R15和SRLV是术后肝功能不全的独立危险因素,回归方程为logit(P)=1.277+0.140×术后ICG R15-5.125×SRLV.术后ICG R15联合SRLV的ROC曲线下面积大于单一的术后ICG R15和SRLV的ROC曲线下面积,分别为0.787,0.713和0.681.结论:术后第3天ICG R15和SRLV是术后肝功能不全的独立危险因素,联合两者建立的回归方程可以较好地预测术后肝功能不全的发生,其诊断价值可能优于单一的术后第3天ICG R15和SRLV.%Objective:To investigate the value of indocyanine green retention rate at 15 minutes (ICG R15) on postoperative day 3 combined with standard remnant liver volume (SRLV) in predicting the occurrence of liver dysfunction after hepatectomyin hepatocellular carcinoma (HCC).Methods:The clinical data of 61 HCC patients undergone hepatectomy in Xiangya Hospital of Central South University from January 2015 to February 2016 were collected and analyzed.The patients were divided into 2 groups:a normal liver function group (n=40) and a liver dysfunction group (n=21).Univariate analysis was used to evaluate the risk factors for postoperative liver dysfunction.Logistic regression was used to assess the independent risk factors for postoperative liver dysfunction,and the regression equation between independent risk factors and postoperative liver dysfunction was established,The receiver operating characteristic (ROC) curve was used to examine the regression equation and compare the value difference in predicting postoperative liver dysfunction between single and combined independent risk factors.Results:Postoperative liver dysfunction occurred in 21 of the 61 patients,with an incidence rate at 34.4％.There was no significant difference in the time of operation,time of hepatic portal occlusion,volume of tumor and volume of resected liver between the 2 groups (all P＞0.05),but there were significant differences in the ICG R15 on postoperative day 3,intraoperative blood loss and SRLV between the 2 groups (all P＜0.05).The ICG R15 on postoperative day 3,intraoperative blood loss,SRLV were the risk factors for postoperative liver dysfunction.Logistic regression analysis showed ICG R15 on postoperative day 3 and SRLV were the independent risk factors for postoperative liver dysfunction,and the regression equation between independent risk factors and postoperative liver dysfunction was as follows:logit(P)=1.277+0.140×ICG R15 on postoperative day 3-5.125×SRLV.The area under the ROC curve ofICG R15 on postoperative day 3 combined with SRLV was more than that of single ICG R15 and single SRLV.Conclusion:ICG R15 on postoperative day 3 and SRLV are the independent risk factors for postoperative liver dysfunction.The regression equation,which is established by combination of ICG R15 with SRLV,can predict the occurrence of postoperative liver dysfunction.The accuracy of ICG R15 on postoperative day 3 combined with SRLV is better than that of single ICG R15 or single SRLV.
