纳米炭在微创肺癌淋巴结清扫术中的应用

目的 评价纳米炭在微创肺癌淋巴结清扫术中的临床应用价值.方法 根据微创胸腔镜辅助淋巴结清扫术中是否运用纳米炭,将42例肺癌患者分为试验组(20例)和对照组(22例),比较两组术中清扫淋巴结的时间、清扫淋巴结的数目、癌性淋巴结转移情况,并观察药物不良反应和围手术期的并发症.结果 局部组织注射纳米炭未发生严重不良反应.试验组与对照组术中清扫淋巴结所用时间分别为(18.3±6.2)和(25.1±5.9)min,差异无统计学意义(P＞0.05);每例患者平均清扫淋巴结25.5和14.6枚,差异有统计学意义(P＜0.01).结论 在微创胸腔镜手术中,应用活性纳米炭对肺癌淋巴结清扫有指导作用,方法可行、有效.

Injection of activated carbon nanoparticles for guiding lymphadenectomy during minimal invasive surgery in lung cancer

OBJECTIVE: To evaluate the clinical value of activated carbon nanoparticles for guiding lymphadenectomy in lung cancer. METHODS: Fourty-two lung cancer patients were divided into two groups: the control group (22 cases) and experiment group (20 cases) who received activated carbon nanoparticles injection around the tumor either by endoscopic injection or intraoperative subserosal injection. The number of dissected lymph node, black-stained lymph node, positive lymph node and the side effect of the procedure were analyzed, respectively. RESULTS: No severe complication was observed in the experiment group. The operative time was not prolonged significantly in the experiment group either. However, the number of average lymph nodes dissected in the experiment group (25.5) was significantly more than that in the control group (14.6) (P <0.01). CONCLUSION: Local injection of activated carbon nanoparticles around the tumor during surgical exploration is effective, safe and easy to do for guiding lymphadenectomy in lung cancer patient.
