目的探讨harmonic focus超声刀在甲状腺癌外科治疗中的临床应用价值,分析超声刀在甲状腺癌手术中的临床优越性。方法回顾性分析2009年10月～2011年4月在我科接受手术的甲状腺癌177例的临床资料,90例采用超声刀治疗(超声刀组),87例采用电刀治疗(传统手术组)。采用统计学检验比较两组的癌灶大小、总手术时间、腺叶切除时间、术后引流量、引流管放置时间、术后并发症发生率、术后甲状旁腺激素及血清钙磷水平变化。结果与传统手术组相比,超声刀组明显缩短了总手术时间和腺叶切除时间(P<0.01),但二者在术后引流量、引流管放置时间、术后并发症发生率、术后甲状旁腺激素及血清钙磷水平变化方面无明显差异(P>0.05)。结论甲状腺癌外科治疗采用超声刀技术,不仅节约了手术时间、简化手术操作,而且对周围组织创伤小,不增加手术并发症、术后引流量及引流时间,值得临床推广使用。
Objective To investigate the clinical value of harmonic focus in the surgical treatment of thyroid cancer and analyze the clinical superiority of ultrasonic knife in the surgery of thyroid cancer. Methods The clinical data of 177 cases of thyroid carcinoma undergoing surgery in our department from October 2009 to April 2011 were analyzed retrospectively. 90 cases were treated by ultrasonic knife (ultrasound knife group) and 87 cases were treated by electric knife (conventional operation group) . Statistical analysis was used to compare the size of the lesion, the total operation time, the time of the gland lobectomy, the amount of postoperative drainage, the drainage tube placement time, the incidence of postoperative complications, parathyroid hormone and serum calcium and phosphorus levels . Results Compared with the traditional operation group, the ultrasonic knife group significantly reduced the total operation time and the time of the glandular lobectomy (P <0.01), but both of them were significantly correlated with postoperative drainage, drainage tube placement time, incidence of postoperative complications, Post-parathyroid hormone and serum calcium and phosphorus levels no significant difference (P> 0.05). Conclusion Surgical treatment of thyroid cancer using ultrasonic knife technology, not only saves the operation time and simplifies the operation, but also has less trauma to the surrounding tissues, does not increase the complications of operation, the amount of drainage and drainage time after operation, which is worthy of clinical promotion.
