Minimally invasive surgery for axillary dissection. Cadaveric feasibility study.
Axillary dissection is the major cause of morbidity in breast cancer and primary cutaneous melanoma of the extremity. In the present study, we examine the potential benefits and advantages of endoscopic axillary lymph node dissection over conventional surgery. Twenty endoscopic axillary dissections and 10 lymph node samplings were performed in 10 cadavers (four male, six female). A preperitoneal distention balloon (PDB) system was used to dissect the axilla. In four of the cadavers, the procedure was followed by open surgery. The axillary contents were examined for lymphatic tissue by a pathologist. The endoscopic technique offered easy access to the axilla and clear visualization of the axillary vein, as well as the long thoracic and thoracodorsal nerves. Results were comparable to those achieved with the classic surgical dissection. Endoscopy is feasible for axillary lymph node dissection and sampling in cases of breast cancer and primary cutaneous melanoma of the extremity. Further studies in patients are needed to reach definitive conclusions.
