超声刀与传统方法行甲亢手术的临床对照研究

Comparison between conventional operation and harmonic scalpel in surgically treating hyperthyroidism-a retrospective clinical study

目的通过对照研究方法,探讨超声刀在甲亢手术治疗中的作用与价值。方法对2003年5月～2008年12月完成的甲亢外科治疗病例,按3种不同情况随机选择每组12例进行对照研究。3组分别为:A组(传统方法首次手术组)、B组(超声刀首次手术组)和C组(超声刀再次手术组)。结果平均手术时间A组:155 min,B组:117 min,两组间差异有显著性(P<0.05);C组:140 min,与A、B组间差异无显著性(P>0.05);平均出血量A组:62.5 mL,B组:21.0 mL,C组:38.0 mL,3组间差异均有显著性(P<0.05);平均术后住院天数A组:7.4 d,B组:6d,C组:6.6 d;A组与B、C组间差异有显著性(P<0.05),B组与C组间无差异;平均伤口引流液量、并发症发生率3组间差异无显著性(P>0.05)。结论超声刀能减少术中出血,缩短手术时间,降低住院天数,在甲亢再次手术中能取得和首次手术相似的效果。超声刀行甲亢手术与传统方法比较具有明显优势。

【Objective】 To study the value of harmonic scalpel in thyroidectomy for the treatment of hyperthyroidism.【Methods】 Cases of hyperthyroidism treated by thyroidectomy between May,2003 and August,2008 were retrospectively analyzed.Cases were manually grouped according to different surgical means which were defined as Group A： initial conventional operation,Group B： initial operation using harmonic scalpel,and Group C： second time using harmonic scalpel after recurrence of hyperthyroidism.【Results】 The average operation time for Group A,B and C were 155,117 and 140 minutes;The average blood loss during operation for Group A,B and C were 62.5mL,21.0mL and 38.0mL respectively;the hospital stay after surgery were 7.4,6.0 and 6.6 days in average for Group A,B and C accordingly.【Conclusion】 The harmonic scalpel surgically applied in the treatment of hyperthyroidism could be beneficial in shortening operation time,reducing blood loss and hospital stay.
