Analysis of the therapeutic effect and postoperative complications related factors of indocyanine green fluorescence guided laparoscopic cholecystectomy for acute cholecystitis
目的 探究吲哚菁绿(ICG)荧光引导腹腔镜胆囊切除术(LC)治疗急性胆囊炎的临床疗效,并分析发生术后并发症的相关因素.方法 回顾性分析2020年9月-2024年9月于该院行LC治疗的279例急性胆囊炎患者的临床资料.其中,行ICG荧光引导LC的179例患者为荧光组[按术前注射剂量和时间分为:A组(47例,15 min,2.5 mg)、B组(45例,30 min,2.5 mg)、C组(48例,30 min,5.0 mg)和D组(39例,60 min 5.0 mg),观察4组术中荧光显影情况],同期行常规LC的100例患者为白光组.比较荧光组和白光组患者围术期指标、肝功能及术后3个月并发症的发生情况;采用多因素Logistic回归模型,分析急性胆囊炎患者行ICG荧光引导LC术后发生并发症的危险因素,并构建决策树模型.结果 A组肝脏荧光强度高于B组、C组和D组,差异有统计学意义(P<0.05);B组的胆囊管与肝脏荧光强度对比值高于A组、C组和D组,差异有统计学意义(P<0.05).荧光组的完全解剖胆囊三角时间、手术时间和术后住院时间明显短于白光组,术中出血量少于白光组,差异均有统计学意义(P<0.05).多因素Logistic回归分析显示,体重指数(BMI)≥25 kg/m2((OR)=3.534,95％CI:1.057～11.811)、发作至手术时间≥72 h((OR)=3.208,95％CI:1.227～8.390)、有三角解剖变异((OR)=2.870,95％CI:1.085～7.590)、胆囊壁厚度≥5 mm((OR)=2.957,95％CI:1.147～7.625)和美国麻醉医师协会(ASA)分级为Ⅲ级～Ⅳ级((OR)=3.179,95％CI:1.245～8.118),均为急性胆囊炎患者行ICG荧光引导LC术后发生并发症的独立危险因素(P<0.05),医师熟练程度≥5年((OR)=0.280,95％CI:0.081～0.970)是急性胆囊炎患者行ICG荧光引导LC术后发生并发症的保护因素(P<0.05).决策树模型显示,医师熟练程度是最重要的预测因子,模型的分类准确率为91.40％.结论 急性胆囊炎患者术前30 min注射2.5 mg的ICG,可获得最佳术中荧光显影.对于行LC治疗的急性胆囊炎患者,ICG荧光引导LC,安全有效,可缩短手术时间,减少出血,加快康复.BMI≥25 kg/m2、发作至手术时间≥72 h、三角解剖变异、胆囊壁厚度≥5 mm和ASA分级为Ⅲ级～Ⅳ级,是急性胆囊炎患者行ICG荧光引导LC术后发生并发症的独立危险因素,医师熟练程度≥5年是保护因素,术前应充分评估,以降低术后发生并发症的风险.
Objective To investigate the clinical efficacy of indocyanine green(ICG)fluorescenceguided laparoscopic cholecystectomy(LC)for acute cholecystitis(AC)and analyze factors associated with postoperative complications(PCs).Methods A retrospective analysis was conducted on 279 AC patients who underwent LC(September 2020 to September 2024).Among them,179 underwent ICG fluorescence guided LC(fluorescence group)and were subdivided by injection timing/dose:group A(47 cases,15 min,2.5 mg),group B(45 cases,30 min,2.5 mg),group C(48 cases,30 min,5.0 mg),and group D(39 cases,60 min,5.0 mg)to assess biliary visualization.Concurrently,100 patients underwent conventional LC(white light group).Perioperative indicators,liver function,and 3-month PCs were compared.Multivariate Logistic regression and a decision tree model identified risk factors for PCs.Results Liver fluorescence intensity was highest in group A(P<0.05).The cystic duct-to-liver fluorescence contrast ratio was highest in group B(P<0.05).The fluorescence group showed shorter Calot triangle dissection time,operative time,postoperative hospital stay,and less intraoperative blood than the white light group(all P<0.05).Multivariate Logistic regression identified independent risk factors for PCs:body mass index(BMI)≥25 kg/m2((OR)=3.534,95％CI:1.057～11.811),onset-to-surgery time≥72 h((OR)=3.208,95％CI:1.227～8.390),anatomical variation of Calot's triangle((OR)=2.870,95％CI:1.085～7.590),gallbladder wall thickness≥5 mm((OR)=2.957,95％CI:1.147～7.625),and American Society of Anesthesiologists(ASA)grade Ⅲ～Ⅳ((OR)=3.179,95％CI:1.245～8.118)(all P<0.05).Surgeon experience≥5 years was a protective factor((OR)=0.280,95％CI:0.081～0.970,P<0.05).The decision tree model(accuracy 91.40％)identified surgeon experience as the most important predictor.Conclusion Preoperative ICG injection(2.5 mg,30 min)provides optimal fluorescence imaging.ICG-guided LC is safe and effective for AC,reducing operative time,blood loss,and hospital stay.Independent risk factors for PCs include BMI≥25 kg/m²,onset-to-surgery time≥72 h,anatomical variation of Calot's triangle,gallbladder wall thickness≥5 mm,and high ASA grade Ⅲ～Ⅳ;Surgeon experience≥5 years is protective.Preoperative thorough evaluation is essential to reduce the risk of postoperative complications.
