目的：探讨LigaSure血管闭合系统在甲状腺良性疾病手术中的应用价值。方法：回顾性分析2012年6月—2014年6月278例因良性甲状腺疾病行手术治疗患者的临床资料，按手术是否使用LigaSure将患者分为LigaSure组（130例）和传统手术统组（148例），比较两组患者的相关临床指标。结果：两组患者术前一般临床资料差异均无统计学意义（均P>0.05）。LigaSure组与传统手术组比较，手术切除范围无统计学差异（P>0.05），手术时间明显缩短（55.2 min vs. 70.8 min，P<0.05），术中出血量明显减少（18.1 mL vs. 35.2 mL，P<0.05），术后常见并发症的发生率及住院时间均无统计学差异（均P>0.05）。结论：甲状腺良性疾病手术中使用LigaSure可简化手术操作，减少手术时间，降低术中出血，值得临床应用。
Application of LigaSure vessel sealing system in surgery for benign thyroid diseases
Objective: To investigate the application value of LigaSure vessel sealing system in surgery for benign thyroid diseases. Methods: The clinical data of 278 patients undergoing surgical treatment for benign thyroid disease from June 2012 to June 2014 were retrospectively analyzed. According to whether using LigaSure or not during surgery, the patients were divided into LigaSure group (130 cases) and traditional surgery group (148 cases). The main clinical variables between the two groups of patients were compared. Results: There was no statistical difference in preoperative general data between the two groups (all P>0.05). In LigaSure group compared with traditional surgery group, the scope of surgical resection showed no significant difference (P>0.05), the operative time was significantly shortened (55.2 min vs. 70.8 min, P<0.05), the intraoperative blood loss was significantly reduced (18.1 mL vs. 35.2 mL, P<0.05), and the incidence of main postoperative complications as well as length of hospitalization had no significant difference (all P>0.05). Conclusion: LigaSure can simplify the surgical procedure, and reduce the operative time and intraoperative bleeding in surgery for benign thyroid diseases. So, it is recommended to be used in clinical practice.
