Da Vinci robot assisted radical gastrectomy with carbon nanoparticle lymph node dyeing for advanced gastric cancer / 中华普通外科杂志

ABSTRACT

Objective To investigate the application value of carbon nanoparticle lymphatic tracer in Da Vinci robot-assisted radical gastrectomy for advanced gastric cancer.Methods The clinical data of 63 advanced gastric cancer patients in Gansu Provincal Hospital in 2016 were analyzed retrospectively.Patients were divided into three groupsrobot with carbon nanoparticle group,laprascopy with carbon nanoparticle group and laprascopy surgury group.Numbers of harvested lymph were compared between the 3 groups,and the perioperative complications were evaluated.Results The number of harvested lymph nodes in carbon nanoparticle group (31.5 ± 3.8) was significantly higher than those of laprascopy joint carbon nanoparticle group (25.3 ± 2.6),F =5.5,P =0.03 and laprascopy group (21.1 ± 2.7),F =6.1,P=0.01.The number of blackdyed harvested lymph node was 481 (76.2％) and the metastasis rate of black-dyed lymph node was 26.8％ in robot joint carbon nanoparticle group.There was no significant difference in the metastasis rate of black-dyed between the robot joint carbon nanoparticle group and laprascopy joint carbon nanoparticle group,x2 =0.17,P =0.22.Condusions The application of diluted carbon nanoparticle lymphatic tracer helps in the dissection of lymph nodes in Da Vinci robot-assisted radical gastrectomy for advanced gastric cancer.
