Application of Nanocarbon in Breast Approach Endoscopic Thyroidectomy Thyroid Cancer Surgery

This study aimed to investigate the application of nanocarbon in surgical endoscopy in patients with thyroid cancer for the clinical tracing of level VI sentinel lymph nodes (SLNs) and for parathyroid gland protection. Ninety-three patients with papillary thyroid carcinoma (PTC) who underwent an endoscopic thyroid cancer operation were included. We randomly divided these patients into a control group (n = 42) and a nanocarbon group (n = 51). For the nanocarbon group, after thyroid exposure, nanocarbon was injected into the thyroid gland, and the SLNs were resected and subjected to frozen sectioning and routine pathological examination. In addition, the postoperative calcium and parathyroid hormone (PTH) levels of both groups were analyzed to compare the features of the nanocarbon application. The number of central lymph (level VI) nodes dissected and the number of metastatic lymph nodes identified were analyzed in both groups. The number of dissected lymph nodes from both unilateral and bilateral thyroid surgeries was significantly larger in the nanocarbon group than in the control group. At the same time, the number of identified metastasis lymph nodes dissected were higher in the nanocarbon group than in the control group. We assessed the postoperative calcium and PTH level to evaluate the parathyroid function. Our results show that the nanocarbon group had a better protective effect on parathyroid function than the control group. As a lymph node trace agent, nanocarbon could better evaluate and permit a more clear lymph dissection for patients with PTC. Nanocarbon contributes to a decrease in the incidence rate of parathyroid damage, which has great clinical value.
