Video-assisted axillary surgery for cancer: non-randomized comparison with conventional techniques.

Endoscopic techniques have been introduced in most of surgical disciplines including surgery for breast cancer. However, there is shortage of evidence-based guidelines and oncological outcome data. We present a controlled trial of endoscopic axillary surgery for breast cancer with mid-term oncologic results. Fifty cases of axilloscopy for sentinel node biopsy, axillary sampling or full axillary dissection were included. Sentinel node biopsy was accomplished with the blue dye technique. Full axillary dissection was performed with a three-port approach with gas insufflation without liposuction. Endoscopic axillary dissection significantly lowered duration of drainage and operative blood loss. Lymph node harvest with endoscopic approach was significantly lower than with open procedure. One case developed axillary recurrence. Endoscopic sentinel node biopsy yielded identification rate of 80%. Current data do not justify the oncological safety of resectional endoscopic procedures. Endoscopically assisted axillary cancer surgery is technically feasible. The technique is valuable to maximize utility of blue dye method for sentinel lymphadenectomy in areas with no access to radio-guided surgery.
