Background Electrocautery has been proven to be associated with prolonged serous drainage that might result in several complications in patients requiring axillary lymph node dissection for breast cancer. We proposed that the Harmonic Focus might outperform electrocautery in axillary lymph node dissection, resulting in shorter operative times and reduced postoperative complications. Patients and Methods One hundred twenty-eight women with confirmed T1-3 N1-2 breast cancer were randomly assigned to undergo mastectomy or breast-conserving surgery with axillary dissection by using Harmonic Focus or electrocautery. Sixty-four has surgery with Harmonic Focus (group A) and 64 with electrocautery (group B) by the same surgical team. Operative time, blood loss, total drainage volume and days, incidence of seroma, hematoma, pain score, and flap necrosis were recorded. Results Using Harmonic Focus significantly diminished operative time, blood loss, total drainage volume, days of stay, and visual analogue scale as compared with traditional electrocautery. There was no statistical difference between the 2 groups regarding seroma, hematoma, and flap necrosis. Conclusion Axillary lymph node dissection using Harmonic Focus is feasible, safe, and a more comfortable design for the surgeon.

The axillary reverse mapping (ARM) procedure can distinguish lymphatics draining the arm from those draining the breast. It has been proposed to preserve lymphatic drainage of the upper limbs and reduce the incidence of upper limb lymphedema during breast cancer surgery. The aim of our study was to assess the feasibility of ARM in modified radical mastectomy and to evaluate its effect on prevention of lymphedema.From January 2012 to March 2014, a prospective study was performed in 265 breast cancer patients who underwent modified radical mastectomy. Patients were divided into 2 groups, 127 patients (47.93%, control group) received a traditional axillary lymph node dissection (ALND), and 138 patients (52.07%, experimental group) received ARM preservation of the nodes and lymphatics during ALND. Radioactive tracer and methylene blue were used for ARM of the nodes and lymphatics. All of the identified ARM nodes were diagnosed using fine needle aspiration cytology for assessment of metastatic status. All resected axillary lymph nodes were conducted in a pathology examination to evaluate tumor metastasis. Data were collected on variations in identification of the ARM nodes and lymphatics, the metastasis of ARM nodes, and the occurrence of lymphedema.In the experimental group, the ARM procedure was successfully conducted in 129 cases (93.48%). ARM nodes metastasis occurred in 11 patients (8.53%). The median follow-up time was 20 months, at the last evaluation there were 42 patients who developed upper limb lymphedema in the control group (33.07%), and in the experimental group the incidence of lymphedema was 5.93% (7/118; P .001). None of the patients had nodal relapses during the follow-up time.ARM appears to be a feasible technique with which to identify upper arm nodes and lymphatics during the modified radical mastectomy procedure. The incidence of lymphedema can be decreased in patients with use of the ARM procedure.
