• Breast cancer
• Vessel sealing system
• Axillary lymph node dissection
• Randomized controlled trial

Objective: This study aimed to compare the efficacy and safety of the newest bipolar vessel sealing system (BVSS; LigaSure (TM) Small Jaw) to that of conventional technique in axillary dissection.
Methods: Sixty-one patients with breast cancer were randomized to a conventional dissection surgical technique (CONV group; n = 30) by scalpel and monopolar cautery or that using a vessel sealing system (BVSS group; n = 31).
Results: There was a significant difference between both groups in the mean number of days until drain removal (6.4 +/- 2.9 vs. 8.2 +/- 3.8 days; P value = 0.033), and the mean total volume of drainage fluid (365.3 +/- 242.2 vs. 625.1 +/- 446.6 mL; P value = 0.009). The incidence of seroma was similar in both groups (43.3 vs. 37.9 %; P value = 0.673). There was no statistically significant difference in axillary dissection operating time (66 vs. 70 min; P value = 0.371), or the mean volume of blood loss (18.2 +/- 31.1 vs. 20.6 +/- 26.3 mL; P value = 0.663).
Conclusions: Our results suggest that BVSS is a more effective device when compared to the conventional techniques in axillary dissection.
