摘 要:目的探讨腹腔镜肝切除术中转开放手术危险因素及构建中转开放手术的风险预测模型。方法回顾性分析2019年6月至2022年5月南方医科大学南方医院肝胆外科收治的938例行腹腔镜肝切除术病人的临床病例信息,依据是否中转开放手术分为腹腔镜组(836例)和中转组(102例),收集所有纳入病人基本信息和临床病例资料,分析两组组间差异及因素,基于多因素分析结果构建中转开放手术列线图预测模型。结果单因素分析结果显示,在有无腹部手术史、有无血管性介入治疗史、是否首次行肝切除、有无腹腔积液、肝肿瘤最大直径、是否为困难肝段切除、切除范围等,差异具有统计学意义(P<0.05)。多因素分析结果显示,有腹部手术史(OR=1.716,95%CI为1.023-2.878)、非首次行肝切除(OR=3.585,95%CI为1.705-7.538)、肝肿瘤最大直径≥5cm(OR=2.680,95%CI为1.646-4.363)、困难肝段切除(OR=2.953,95%CI为1.755-4.967)、肝段切除范围≥3个肝段(OR=1.901,95%CI为1.099-3.290)为腹腔镜肝切除术中转开放手术的独立危险因素(P均<0.05)。依据多因素分析结果,纳入5个独立危险因素变量,构建腹腔镜肝切除术中转开放手术的列线图模型。模型的C-index为0.746(95%CI为0.692-0.800),Hosmer-Lemeshow拟合优度检验结果P=0.541>0.05,绘制ROC曲线,曲线下面积(AUC)为0.746(95%CI为0.692-0.800,P<0.001)。绘制的临床决策曲线(DCA)结果示在阈值概率范围0.05~0.70内模型具有临床效用。结论有腹部手术史,非首次行肝切除,肝肿瘤最大直径≥5 cm,困难肝段切除,肝段切除范围≥3个肝段是腹腔镜肝切除术中转开放手术的独立危险因素。基于此构建的列线图模型的校准曲线拟合程度理想,在预测的中转开放手术率与实际的中转开放手术率有较好的一致性,模型具有良好预测能力,但仍有待行外部验证来进一步证实。Objective To investigate the risk factors of conversion to laparotomy during laparoscopic hepatectomy and establish a risk prediction model for the conversion.Methods Clinical case information of 938 patients undergoing laparoscopic hepatectomy admitted to the Department of Hepatobiliary Surgery,Nanfang Hospital of Southern Medical University from June 2019 to May 2022 was retrospectively analyzed.The patients were divided into laparoscopic group(836 cases)and conversion group(102 cases)according to whether were transferred to open surgery.Basic information and clinical case data of all included patients were collected.The differences between the two groups and their factors were analyzed,and R language was used to establish and evaluate the prediction model of conversion nomograms based on the results of multi-factor analysis.ResultsThe results of single-factor analysis showed that:Between the two groups of comparisons,there were statistically significant differences in the history of abdominal surgery,history of vascular interventional therapy,being or being not the first hepatic resection,presence or absence of ascites,the maximum diameter of liver tumor,difficult location hepatectomy and resection scope(P<0.05).The results of multi-factor analysis showed that:History of abdominal surgery(OR=1.716,95%CI 1.023-2.878),non-first-time hepatectomy(OR=3.585,95%CI 1.705-7.538),maximum diameter of liver tumor≥5cm(OR=2.680,95%CI 1.646-4.363),difficult location hepatectomy(OR=2.953,95%CI 1.755-4.967),and scope of hepatectomy≥3 liver segments(OR=1.901,95%CI1.099-3.290)were independent risk factors for conversion to laparotomy during laparoscopic hepatectomy(P<0.05).According to the results of multivariate analysis,including the five independent risk factor variables,the nomogram prediction model of laparoscopic liver resection converted to laparotomy was constructed.The C-index of the model was 0.746(95%CI 0.692-0.800),the P value of Hosmer and Lemeshow Test was 0.541>0.05,R0C curve was drawn,and the area under the c
