[摘 要] 目的:探讨在达芬奇机器人胃癌根治术中应用吲哚菁绿(indocyanine green,ICG)近红外光成像示踪技术引导D2淋
巴结清扫的安全性和有效性。方法:回顾性纳入2021年1月—2024年1月在南京中医药大学附属医院普外科行达芬奇机器人
胃癌根治术的患者,其中60例术中采用ICG荧光导航进行淋巴结清扫(ICG组),117例进行常规淋巴结清扫(非ICG组),通过
倾向性评分匹配(1∶1)平衡基线特征。比较两组淋巴结清扫数量、手术相关指标、术后并发症发生率、住院时间及术后康复数
据。结果:匹配后ICG组和非ICG组各60例,两组的年龄、性别、体重指数、营养评分、肿瘤直径、肿瘤部位、分化程度、脉管侵
犯、Lauren分型均衡可比(P均>0.05)。所有患者均完成规定范围的淋巴结清扫,术后无荧光淋巴结残留。ICG组淋巴结平均
清扫数量为(33.73±12.66)枚,显著高于非ICG组(26.15±6.31)枚(P < 0.05);但两组术后病理检出的阳性淋巴结数量差异无统计
学意义[1(0,6)枚 vs. 0(0,4)枚,P > 0.05)。ICG组D1和D2区域的淋巴结清扫数量均显著高于非ICG组(P均<0.05);且在3、
4d、6、7、8a、12a 站淋中巴结清扫中显示出优势。两组的手术时间、术中出血量、术后住院时间、术后并发症发生率及术后第
3 天 C 反应蛋白(C⁃reactive protein,CRP)、白细胞计数(white blood cell,WBC)、白蛋白(albumin,Alb)、天门冬氨酸氨基转移酶
(aspartate aminotransferase,AST)/丙氨酸氨基转移酶(alanine aminotransferase,ALT)差异均无统计学意义(P 均>0.05);而 ICG
组的通气时间短于非ICG组,差异有统计学意义(P < 0.05)。结论:ICG近红外光成像示踪技术在机器人胃癌根治术中的应用
能够提高淋巴结清扫的精确性和彻底性,且不影响围手术期安全性。

[Abstract] Objective:This study aims to explore the safety and efficacy of utilizing indocyanine green near⁃infrared(ICG⁃NIR)
fluorescence imaging to guide lymph node(LN)dissection during Da Vinci robotic gastrectomy(RG). Methods:The patients who
underwent RG at the General Surgery Department of Affiliated Hospital of Nanjing University of Chinese Medicine from January
2021 to January 2024 were retrospectively analyzed. Among them,60 patients underwent ICG fluorescence navigation ⁃ guided
lymphadenectomy(ICG group),while 117 received conventional LN dissection(non⁃ICG group). Propensity score matching(1∶1)was
performed to balance baseline characteristics. The number of retrieved LNs,surgical outcomes,postoperative complications,hospital
stay,and recovery data were compared between two groups. Results:After matching,each group comprised 60 patients with
comparable baseline characteristics,including age,sex,body mass index,nutritional risk screening scores,tumor diameter,tumor
location,differentiation,vascular invasion,and Lauren type(all P > 0.05). All patients completed D2 lymphadenectomy,and there
were no fluorescent LNs remaining after surgery. The ICG group had a significantly higher mean number of retrieved LNs(33.73±
12.66)than the non⁃ICG group(26.15±6.31,P < 0.05). Nevertheless,there was no significant difference in the number of positive LNs
