Abstract:
e12014 Background: The objective of this study was to compare the potential advantages of the harmonic scalpel with those of electrocautery for axillary lymph node dissection in breast surgery. Methods: A prospective randomized study of axillary lymph node dissection procedures performed between March 2011 and September 2012 was conducted. Primary breast cancer patients with axillary node-positive status (n = 25) were randomly assigned to the harmonic scalpel (group A, n = 13) or electrocautery (group B, n = 12) groups.The patients underwent breast-conservation surgery or mastectomy with a level I and II axillary dissection, which was performed by one surgeon. The time required for resection and the blood loss during the lymphadenectomy were recorded. The HARMONIC FOCUS (Ethicon Endo-Surgery, Inc.) was used as the ultrasonic scalpel. A low-pressure vacuum drain was placed in the axilla and removed when the drainage volume reduced to less than 50 ml over 24 hours. After the operations, the patients were assessed for the presence of seroma in an outpatient setting. Results: Resection timein group A was significantly shorter than that in group B (mean, 28.6 ± 5.1 vs. 40.3 ± 5.6 min; P = 0.0001). Similarly, blood loss in group A was significantly lower than that in group B (mean, 7.9 ± 5.3 vs. 22.9 ± 11.5 ml; P = 0.001). Duration of drain placement in group A was significantly lower than that in group B (mean, 3.5 ± 1.1 vs. 5.0 ± 0.9 days; P = 0.01), and the seroma rate in group A was lower than that in group B (23% vs. 66%; P = 0.04). Conclusions: For axillary lymph node dissection, the harmonic scalpel is more effective in terms of resection time, blood loss, duration of drain placement, and postoperative seroma formation.
