[Application of carbon nanoparticle in neck Ⅵ lymph node dissection for papillary thyroid carcinoma].

To investigate the application value of carbon nanoparticle lymph tracer in Ⅵ lymph node dissection for papillary thyroid cancer.One hundred and forty-eight patients with papillary thyroid cancer from October 2015 to May 2016 were enrolled into the retrospective analysis. Seventy-five cases with carbon nanoparticle injected in operation were divided into observation group, while the other seventy-three cases without lymph tracer were divided into control group. The number of neck Ⅵ lymph nodes and metastatic lymph nodes between the two groups were compared, as well as the incidence of parathyroid injury and postoperative hypocalcemia. There were no significant difference in age, gender, tumor size, pathology or type of operation between the two groups(>0.05). Parathyroid injury incidence in the observation group significantly lower than the control group (5.33% vs 5.33%, < 0.05). There was significant difference in the number of neck Ⅵ lymph node dissection between the two groups (observation group: 6.51±4.65, control group: 4.42±3.10, < 0.05).Carbon nanoparticle injected as a lymph tracer in thyroid surgery is helpful, the characteristics of the parathyroid gland negative imaging can effectively decrease the rate of parathyroid gland injury.
