Improving results of superiority of ultrasonic knife applied in laparoscopic surgery have led to growing acceptance of this approach as a potentially hemostatic method for “open “operation, and recently, harmonic scalpel are turn into an burgeoning tool and effective surgical instruments for sharp dissection, stanch bleeding, dissection and haemostasis in axillary dissection of breast cancer.Accumulating clinical evidence indicates that harmonic scalpel had more advantages than electrocautery in axillary dissection, however, the conclusion of superiority remains inconclusive.Therefore, we aimed to assess the utility and advantages of this instrument compared with electrocautery to perform axillary dissection.


A retrospective case-control study was designed to present the therapeutic effect of two surgical instruments respectively(Harmonic scalpel vs electrocautery).The surgical and pathosis details of 23 breast cancer patients who underwent axillary dissection using the ultrasound scissors were compared with 23 breast cancer patients, matched for age, Body surface area (BSA) and stage of disease, operated by the same surgical team using electrocautery during the same period.The results were evaluated in terms of intra-operative blood loss, operating time, postoperative drain volume and drain days, wound infection, postoperative pain, mobility of the shoulder, and hospitalization stay duration.


There was no significant difference in the operating time between the ultrasound scissors and electrocautery group (90.22±17.74 and 93.04±19.41 mins, p > 0.05). The blood loss (33.04 ± 18.2 ml and 89.78 ± 49.14 ml, p 


Axillary dissection can be safely performed using ultrasound scissors with a significant reduction in blood loss, duration of drainage and hospitalization stay compared to electrocautery.
