目的

对比纳米碳与吲哚菁绿(ICG)在腹腔镜胃癌根治术淋巴结清扫方面的优劣性。

方法

回顾性分析2016年1月至2019年12月接受腹腔镜胃癌根治术的167例患者资料，根据所使用的示踪剂种类，分为纳米碳组130例、ICG组37例，应用GraphPad Prism 8.0统计软件进行分析，围术期指标及淋巴结清扫数目等计量资料以(±s)表示，采用独立t检验；术后并发症、二次手术率等计数指标比较采用χ2检验，P<0.05为差异有统计学意义。

结果

两种示踪剂对不同病理分期胃癌的淋巴结清扫效果差异无统计学意义。在各种胃癌根治术式中，淋巴结分拣均有助于提高淋巴结总检出数。纳米碳组较ICG组更有助于提高根治性全胃切除术第5站淋巴结的清扫数目(P＝0.02)、根治性近端胃切除术第1站淋巴结的清扫数目(P＝0.03)以及根治性远端胃淋巴结的总清扫数目(P＝0.03)。在提高淋巴结检出率方面，两种示踪剂差异无统计学意义。

结论

纳米碳与吲哚菁绿在不同病理分期中的总体淋巴结清扫效果差异无统计学意义。无论使用何种示踪剂，均提倡淋巴结分拣。纳米碳较吲哚菁绿更有助于提高根治性全胃第5站淋巴结的清扫数、根治性近端胃第1站淋巴结的清扫数以及根治性远端胃淋巴结的总清扫数目。

Objective

To compare the advantages between carbon nanoparticles (CN) and indocyanine green (ICG)-guided lymphadenectomy in laparoscopic radical gastrectomy.

Methods

Between January 2016 and December 2019, clinical data of 167 patients underwent laparoscopic radical gastrectomy were analyzed retrospectively. Among them, 130 patients received CN-guided gastrectomy and the other 37 patients received ICG-guided gastrectomy. GraphPad Prism 8.0 was employed for data analysis. Measurement data were presented as, and analyzed by using unpaired t-test. Count data were presented as frequency, and were compared by using χ2 test. A P value of <0.05 was considered as statistical significant difference.

Results

The total number of harvested lymph nodes were similar in patients with same pathological stage. Lymph node examination could improve the number of retrieved lymph nodes. CN is superior to ICG in the harvest of No.5 lymph nodes in laparoscopic total gastrectomy, No.1 lymph nodes in laparoscopic proximal gastrectomy and total number in laparoscopic distal gastrectomy. Statistical difference in the positive rate of lymph node was not observed between two groups.

Conclusions

The effect of CN and ICG in guiding lymph node dissection was similar in patients with same pathological stage. Lymph node examination should be encouraged in laparoscopic radical gastrectomy. CN was superior than ICG in the harvest of No.5 in laparoscopic total gastrectomy, in the harvest of No.1 in laparoscopic proximal gastrectomy and total number of lymph nodes in laparoscopic distal gastrectomy.
