吲哚菁绿（ICG）荧光成像技术基于ICG独特的代谢特性及近红外光激发特性, 通过动态荧光显影成像为手术提供精准导航, 其在肝胆胰外科领域展现出重要的应用价值。随着多版国内外指南的迭代更新, ICG荧光导航技术已被确立为肝胆胰外科手术的重要辅助手段, 其安全性和有效性得到充分验证。文章就ICG荧光成像技术的原理、在肝胆胰外科应用中的现状、在临床应用中面临的问题以及其应用展望展开综述。

       Based on the unique metabolic properties and near-infrared light excitation characteristics of indocyanine green（ICG）, the ICG fluorescence imaging technology provides dynamic fluorescence imaging for precise surgical navigation．This technology has demonstrated significant value in hepatobiliary and pancreatic surgery．With iterative updates to international and domestic guidelines, ICG-based fluorescence navigation has been established as an essential adjunctive tool in hepatopancreaticobiliary procedures, with its safety and efficacy validated through extensive clinical research．This review systematically explores the underlying principles of ICG fluorescence imaging, its current applications in liver, biliary, and pancreatic surgeries, the challenges encountered in clinical practice, and future directions for technological optimization and clinical translation

目的 探讨胆固醇胆囊息肉形成的高危因素。方法 将广州市第一人民医院住院的219例接受腹腔镜胆囊切除的患者按照术后胆囊病理结果分为胆固醇息肉组（162例）和非胆固醇息肉组（57例）。对所有研究对象的年龄、性别、血脂水平、肝功、超敏C反应蛋白、CA199、癌胚抗原（CEA）、胆囊结石病史、糖尿病病史、肝硬化病史进行数据收集及统计学处理。结果 经非参数检验方法Mann-Whitney U分析结果显示：1. 脂代谢相关指标在胆固醇息肉组和非胆固醇息肉组间比较差异有统计学意义;2. 总胆固醇指标在胆固醇息肉组高于非胆固醇息肉组,且高于参考值范围;3. 胆固醇息肉组和非胆固醇息肉组比较部分脂代谢指标有统计学意义,但均在参考值范围内。胆固醇息肉形成的Logistic回归分析：得到的Logistic模型差异有统计学意义,χ²=179.14,P<0.001。模型纳入的8个自变量中,总胆固醇每增加一个单位,发生胆固醇息肉的风险相比于非胆固醇息肉组将增加38.2倍（P<0.05）。结论 总胆固醇是胆囊胆固醇息肉形成的高危因素。

Objective To investigate the risk factors of cholesterol polyps formation．Methods The 219 patients who underwent laparoscopic cholecystectomy in Guangzhou First People's Hospital were divided into cholesterol polyps group（162 cases）and non-cholesterol polyp group（57 cases）according to postoperative gallbladder pathological results．The age,gender,blood lipids levels,liver function,high-sensitivity C-reactive protein,CA199,carcinoembryonic antigen（CEA）,history of gallstones,diabetes,and liver cirrhosis of all patients were collected and statistically processed．Results Mann-Whitney U analysis by nonparametric test method showed that the lipid metabolism-related indexes were significantly different between the cholesterol polyps group and the non-cholesterol polyp group．The total cholesterol indexes in the cholesterol polyps group were higher than those in the non-cholesterol polyp group,and higher than the reference range．The cholesterol polyps group and the non-cholesterol polyp group had statistical significance in some lipid metabolism indexes,but they were all in the normal range．Logistic regression analysis of cholesterol polyps formation showed the obtained Logistic model was statistically significant,χ²=179.14,P<0.001．Among the 8 independent variables included in the model,total cholesterol was statistically significant．For each unit increased in total cholesterol,the risk of developing cholesterol polyps increased by 38.2 times compared with the non-cholesterol polyp group．Conclusions Total cholesterol is a high risk factor for the formation of cholesterol gallbladder polyps．
