Endoscopic techniques are promising in breast surgery. In order to create working space, liposuction is widely used in video-assisted breast surgery (VABS). However, the use of liposuction is likely associated with side effects that may partly limit the application of VABS. Therefore, a new technique of endoscopic axillary lymphadenectomy without prior liposuction was developed by our group. A total of 106 female patients underwent VABS, with special adaptation of the video-assisted surgical procedures previously described. Differing from other endoscopic surgery techniques, our adaptations of VABS included the selection of the working instruments, trocar placement, creation of working space, order of axillary lymph node dissection and method of mastectomy. The operative time was 50-180 min (mean, 85.5 min). The intraoperative blood loss ranged from 20 to 100 ml (mean, 48 ml). The mean lymph node number harvested was 11.5 (range, 6-31). No serious intra- or postoperative complications were recorded. There was no axillary tumor relapse, trocar site tumor implantation or upper limb edema. Without prior liposuction, our new technique of VABS reduced the blood loss volume, endoscopic surgery time, total volume of drainage fluid and, most importantly, the risk of port-site metastases. This new technique appears to have great clinical potential and good prospects for future endoscopic breast surgery development.
