超声刀在乳腺癌改良根治术腋窝淋巴结清扫中的应用

目的 研究超声刀与电刀在乳腺癌改良根治术腋窝淋巴结清扫中的临床效果.方法 回顾性分析429例行乳腺癌改良根治术患者的临床资料,腋窝淋巴结清扫中采用超声刀治疗178例（超声刀组）,采用电刀治疗251例（电刀组）,比较两组手术出血量、手术时间、拔管时间、引流总量、皮下积液发生情况.结果 两组患者均顺利完成手术,腋窝淋巴结清扫时均无腋血管和胸长神经、胸背神经的损伤.超声刀组手术出血量、手术时间、拔管时间、引流总量均优于电刀组（98.0±10.2） ml比（152.0±11.5） ml、（125.0±9.6） min比（155.0±12.3） min、（6.0±2.1）d比（9.0±4.3）d、（227.0±10.6） ml比（319.0±15.8） ml],差异均有统计学意义（P＜ 0.05或＜0.01）,而两组皮下积液发生率比较差异无统计学意义（P＞0.05）.结论 在乳腺癌改良根治术腋窝淋巴结清扫中采用超声刀能显著缩短手术时间、减少手术出血量、减少拔管时间和引流总量.

The application of ultrasound scalpel in axillary lymph node dissection in modified radical mastectomy for breast cancer

Objective To study the effect of the ultrasound scalpel and electric knife in axillary lymph node dissection in modified radical mastectomy for breast cancer.Methods The clinical data of 429 patients with modified radical mastectomy for breast cancer were analyzed retrospectively.The axillary lymph node dissection in 178 cases were performed with the ultrasound scalpel （ultrasound scalpel group） and 251 cases were done with the electric knife（electric knife group）.The blood loss,operative time,extubation time,the total amount of drainage,the incidence of seroma were compared.Results Two groups were successfully operated,no axillary vessels and long thoracic nerve,chest nerve injury.The blood loss,operative time,extubation time,the total amount of drainage in ultrasound scalpel group were significantly better than those in electric knife group （98.0 ± 10.2） ml vs.（152.0 ± 11.5） ml,（125.0 ±9.6） min vs.（155.0 ± 12.3） min,（6.0 ± 2.1） d vs.（9.0 ± 4.3） d,（227.0 ± 10.6） ml vs.（319.0 ± 15.8） ml,P＜ 0.05 or ＜ 0.01].The incidence of seroma was no significant difference between two groups （P ＞ 0.05）.Conclusions Using ultrasound scalpel in axillary lymph node dissection for breast cancer can significantly reduce operative time,and is consistent with less blood loss,less extubation time and the total amount of drainage.
