甲状腺癌手术中纳米碳示踪保护甲状旁腺的研究

Protective effect of carbon nanoparticles tracer on parathyroid glands in the operation of thyroid carcinoma

目的探讨在甲状腺癌手术中采用纳米碳淋巴示踪剂保护甲状旁腺的作用。方法回顾性分析我院2014年1月至10月收治的65例甲状腺癌患者的临床资料,按是否在甲状腺内注射纳米碳分成2组,实验组30例患者操作开始前在甲状腺内注射纳米碳,对照组35例未注射纳米碳,实验组行甲状腺患侧腺叶+峡叶+对侧腺叶次全切除术22例,行双侧甲状腺全切除术8例,对照组行甲状腺患侧腺叶+峡叶+对侧腺叶次全切除术25例,行双侧甲状腺全切除术10例。2组患者均联合中央区淋巴结清扫术。结果纳米碳可使中央区淋巴结黑染,而甲状旁腺不黑染。实验组每例显露(2.6±0.8)枚甲状旁腺,误切0枚;对照组每例显露(1.9±0.7)枚甲状旁腺,误切3枚,2组之间差异有统计学意义(P<0.05)。2组患者均未发生永久性甲状旁腺功能低下,实验组有1例暂时性甲状旁腺功能低下,对照组有2例甲状旁腺功能低下,差异无统计学意义。结论纳米碳混悬液有利于术中甲状旁腺的识别,降低甲状旁腺误切率,但不能降低术后甲状旁腺功能低下的发生率。

Objective To discuss the protective effect of carbon nanoparticles lymphatic tracer on parathyroid glands in the operation of thyroid carcinoma. Methods Retrospectively analyzed the clinical data of 65 thyroid carcinoma patients from January 2014 to October 2014, and they were divided into 2 groups according to whether injected with carbon nanoparticles. The experimental group （30 cases） were injected with carbon nanoparticles in thyroidglands before major procedure, while the control group （35 cases） were not injected. In the experimental group, there were 22 cases accepted total thyroidectomy of the affected side gland ＋ isthmus thyroidectomy ＋ subtotal thyroidectomy of the offside gland, and 8 cases of total thyroidectomy. In the control group, there were 25 cases accepted total thyroidectomy of the affected side gland ＋ isthmus thyroidectomy ＋ subtotal thyroidectomy of the offside gland,and 10 cases of total thyroidectomy. And all the 65 cases ac-cepted centrallymph nodes dissection. Results After carbon nanoparticles injection, central lymph nodes became black while parathyroid glands did not become black. The experimental group showed （2. 6 ± 0. 8） parathyroids each patient, and no parathyroid was cut by mis-take;the control group showed （1. 9 ± 0. 7） parathyroids each patient, and 3 parathyroids were cut by mistake. and the difference between the two groups was statistical meaningful （P〈0. 05）. There was no permanent hypoparathyroidism in the two groups. There was 1 cases of temporary hypoparathyroidism occured in the experimental group, and 3 cases occured in the control group, and there was no statistical sig-nificance difference between the two groups. Conclusion Carbon nanoparticles is benefit to the identification of parathyroid in surgery, and it can reduce the incidence of inadvertent parathyroidectomy, but it cann’ t reduce the incidence of hypoparathyroidism after procedure.
