Transareolar endoscopy-assisted partial mastectomy: a preliminary report of six cases.

Six patients with breast cancer in the upper inner quadrant underwent endoscopy-assisted partial mastectomy. The tumor was removed with a 2-cm-wide surgical margin through a periareolar semicircular incision using a special retractor and endoscope system for plastic surgery. Another small incision was made in the axilla for total lymph node dissection or sentinel lymph node biopsy. The average of total operation time in five patients who underwent partial mastectomy was 241 minutes (range, 190-315 minutes), and the average time for the procedure of partial mastectomy in six cases was 84 minutes (range, 69-113 minutes). The cosmetic outcome was excellent. Transareolar endoscopic partial mastectomy can be considered as an alternative surgery option and can offer great cosmetic advantage for patients with small cancers in the inner quadrants of the breast.
