The purpose of this prospective study is to evaluate the efficacy of ultrasonically activated shears (UAS) in hemostasis as well as its safety in regard to complications in thyroid surgery.
Three hundred patients who had undergone surgery on the thyroid gland were divided into 2 groups of 150 patients each. Hemostasis as well as division of blood vessels and thyroid tissue were performed with the use of UAS in the first group and by conventional ligations in the second group.
The use of UAS resulted in as much as a 39.7% reduction in the operative time of the total thyroidectomy and a 30.8% reduction of the lobectomy (p < .001). However, there was no important difference in the postoperative blood loss in either the temporary hypoparathyroidism or the paresis of recurrent laryngeal nerves.
The use of UAS in thyroid surgery is a safe method for hemostasis, as well as for the division of blood vessels and thyroid tissue. It leads to the reduction of the total operative time without serious complications.
本前瞻性研究的目的是评估超声激活剪刀（UAS）在甲状腺手术中的止血效果及其在并发症方面的安全性。
300例行甲状腺手术的患者被分为两组，每组150例。第一组使用UAS进行止血以及血管和甲状腺组织的分离，第二组采用传统结扎方法。
使用UAS使全甲状腺切除术的手术时间减少了39.7%，叶切除术的手术时间减少了30.8%（p <.001）。然而，在术后出血量、暂时性甲状旁腺功能减退或喉返神经麻痹方面没有显著差异。
在甲状腺手术中使用UAS是一种安全的止血方法，也是分离血管和甲状腺组织的安全方法。它可减少总手术时间且无严重并发症。
