ABSTRACT

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.
