Total Sealing Technique (TST) with a bipolar vessel sealing system reduces lymphorrhea and seroma formation for axillary lymph node dissection in primary breast cancer
Abstract
Background: The purpose of this study is to evaluate the potential of a novel surgical procedure, the Total Sealing Technique (TST), using the latest bipolar vessel sealing system (BVSS; LigaSure™ Exact Dissector) to reduce lymphatic leakage and seroma formation after electrocautery axillary lymph node dissection (ALND) in breast cancer surgery. Prolonged drainage is a common occurrence after ALND, primarily due to lymphatic leakage. In addition, the presence of seroma often leads to delays in the administration of postoperative adjuvant chemotherapy even after drain removal. Methods: We conducted a comparative analysis of 36 patients who underwent total mastectomy with ALND using conventional electrocautery technique (CONV) during the first 3 years, and 35 patients who underwent the same procedure using TST during the subsequent 3 years. The following factors were compared to assess the impact of TST: operation time, blood loss, total drainage volume, mean time to drain removal, postoperative hospital stay, mean time to initiation of postoperative chemotherapy, and postoperative complications in each group. Results: TST significantly reduced drainage volume (360.5 vs. 820.6 mL, p < 0.001), days to drain removal (4.8 vs. 6.8 days, p < 0.001), postoperative hospital stay (5.9 vs. 9.6 days, p < 0.001), the incidence of seroma (28.6 % vs. 65.9 %, p = 0.001), and time to chemotherapy initiation (33.1 vs. 61.4 days, p < 0.001) compared to CONV. Conclusions: TST in total mastectomy with ALND effectively decreases the incidence of lymphorrhea and seroma formation; thus, it can be recommended for total mastectomy with ALND.
