Résumé
Objective To analyze the effect and the operative skill of ultrasonic activated shears(UAS) in thyroid surgery.Methods The clinical data of 95 patients who received thyroidectomy in our hospital from May 2008 to May 2011 were retrospectively analyzed.They were divided into two groups,45 patients were given traditional method (control group),50 patients were given UAS (UAS group).Results Mean operating time in control group was 114(81-184)min,that in UAS group was 75(44-131) min.Mean quantity of operating bleeding in control group was 65(32-695)ml,that in UAS group was 27(6-147) ml.Mean time of postoperative hospitalization in control group was 4.6(3-7)days,that in UAS group was 3.8(2-6)days.Conclusion It is convenient to master UAS.Compared with conventional method,it can reduce operating time in thyroid surgery,length of incision,quantity of postoperative bleeding and postoperative length of stay.Therefore,it is safe and effective in thyroid open surgey.
