吲哚菁绿荧光导航在腹腔镜胃癌根治术中应用价值
Clinical value of indocyanine green fluorescence navigation in laparoscopic radical gastrectomy for gastric cancer
背景与目的 腹腔镜胃癌根治术中淋巴结清扫的彻底性直接影响术后患者预后。吲哚菁绿(ICG)荧光导航技术作为新兴辅助手段,能实时显影淋巴引流路径,辅助提高手术精准性。本文探讨ICG荧光导航在腹腔镜胃癌D2根治术中对淋巴结清扫、阳性淋巴结识别及患者预后的影响。 方法 回顾性分析2021年1月—2022年12月于福建医科大学附属漳州市医院行腹腔镜胃癌根治术的168例患者资料,其中51例接受ICG导航手术(ICG组),117例为常规手术(非ICG组)。比较两组在围手术期指标、淋巴结清扫情况、阳性淋巴结检出能力及术后生存情况等方面的差异。 结果 两组患者的基线临床病理资料及手术时间、术中出血量、术后恢复情况、外科并发症发生率差异均无统计学意义(均P>0.05)。ICG组平均清扫淋巴结数明显多于非ICG组(48.62枚vs. 37.20枚,P<0.001),清扫≥30枚的比例也更高(92.16% vs. 69.23%,P=0.001)。分层分析显示,ICG组在D2站、胰腺上区域(第7、8、9、11组)、全胃切除、T3~4期、Ⅲ期等患者中淋巴结清扫数明显增多(均P<0.01)。ICG组中显影淋巴结的检出数和阳性数均明显高于非显影淋巴结(30.31枚vs. 17.36枚;2.03枚vs. 0.94枚,均P<0.05)。ICG荧光成像对阳性淋巴结的诊断敏感度为68.4%,非显影淋巴结的阴性预测值为94.6%。两组在术后辅助治疗情况相似,总生存率(HR=0.737,P=0.471)和无病生存率(HR=0.502,P=0.089)无明显差异。 结论 ICG导航在腹腔镜胃癌根治术中具有良好的安全性,显著提高胰腺上区域、全胃切除及较晚分期胃癌患者的淋巴结清扫数量,增强阳性淋巴结识别能力,但短期内尚未观察到生存获益。该技术有望进一步优化术中导航策略,提升手术质量,且需开展长期随访及多中心研究加以验证。
Background and Aims The completeness of lymph node dissection in laparoscopic radical gastrectomy for gastric cancer directly affects postoperative patient prognosis. Indocyanine green (ICG) fluorescence-guided navigation, as an emerging auxiliary technique, enables real-time visualization of lymphatic drainage pathways and enhances surgical precision. This study was performed to evaluate the impact of ICG fluorescence navigation on lymph node dissection, positive lymph node detection, and patient prognosis during laparoscopic D2 radical gastrectomy for gastric cancer. Methods The clinical data of 168 patients who underwent laparoscopic radical gastrectomy at Zhangzhou Affiliated Hospital of Fujian Medical University from January 2021 to December 2022 were retrospectively analyzed. Among them, 51 patients received ICG-guided surgery (ICG group), and 117 underwent conventional surgery (non-ICG group). Perioperative variables, extent of lymph node dissection, positive lymph node detection efficiency, and postoperative survival outcomes were compared between the two groups. Results There were no statistically significant differences between the two groups in baseline clinicopathologic characteristics, as well as operative time, intraoperative blood loss, postoperative recovery, and incidence of surgical complications (all P>0.05). The ICG group had a significantly higher mean number of lymph nodes dissected than the non-ICG group (48.62 vs. 37.20, P<0.001), with a greater proportion of patients achieving ≥30 nodes dissected (92.16% vs. 69.23%, P=0.001). Stratified analysis showed a significantly higher number of dissected lymph nodes in the ICG group at D2 stations, the supra-pancreatic region (stations 7, 8, 9, 11), in total gastrectomy, T3-4 stage, and stage Ⅲ patients (all P<0.01). In the ICG group, the number and positivity rate of fluorescent lymph nodes were significantly higher than those of non-fluorescent nodes (30.31 vs. 17.36; 2.03 vs. 0.94, both P<0.05). The diagnostic sensitivity of ICG fluorescence imaging for positive lymph nodes was 68.4%, with a negative predictive value of 94.6% for non-fluorescent nodes. No significant differences were observed between the two groups in terms of adjuvant therapy, overall survival (HR=0.737, P=0.471), or disease-free survival (HR=0.502, P=0.089). Conclusion ICG-guided navigation in laparoscopic radical gastrectomy for gastric cancer is safe and significantly improves lymph node yield, particularly in the supra-pancreatic region, total gastrectomy, and advanced-stage patients. It also enhances positive node detection. However, no survival benefit has been observed in the short term. Further multicenter studies with long-term follow-up are warranted to confirm its clinical value and optimize intraoperative navigation strategies.
