内镜甲状腺手术评分系统的研究

Study on the operation score system for endoscopic thyroidectomy

目的探究内镜甲状腺手术评分系统的临床意义。方法建立以内镜甲状腺6项技术指标为标准的手术评分系统。将单一术者于2001年7月至2007年12月连续施行的300例内镜甲状腺手术按照时间顺序平均分为10组，每组30例。对300例患者手术评分系统各项指标结果结合总体手术时间等进行分析。结果300例手术患者平均手术总评分6．0分；平均手术时间98．1min；各组手术总评分均数、6项单项手术评分均数及手术时间均数差异均有统计学意义（P〈0．05）；相邻组间手术评分第2组与第3组差异有统计学意义（P〈0．05），第5组与第6组差异有统计学意义（P〈0．05）。结论内镜甲状腺手术评分系统对判断手术熟练程度及稳定性具有指导意义。

Objective To investigate the clinical significance of the operation score system for endoscopic thyroidectomy. Methods An operation score system based on 6 important procedure skills of endoscopic thyroidectomy was established. And a retrospective study of the first 300 consecutive patients underwent endoscopic thyroidectomy from July 2001 to December 2007 by a single surgeon was performed. The patients was divided into 10 consecutive groups chronologically, each comprising 30 cases. Results The mean operation score of all the patients was 6. 0 and the mean operation time was 98. 1 min. There were significant differences in the mean operation score, every skill score and the mean operation time among the 10 groups. In the consecutive two groups comparison, significant differences in the operation scores were observed between group 2 and 3 （ P 〈 0. 05 ） and between group 5 and 6 （ P 〈 0. 05 ）. Conclusion The operation score system for endoscopy thyroidectomy is a useful method to judge the proficiency and the stability of the operation.
