Abstract: Objective To compare the therapeutic effect of Ultrasonically Activated Scalpel(UHS)with electrotome in axillary lymph node dissection(ALND)of breast cancer.Methods A retrospective analysis was performed on 105 patients who received modified radical mastectomy.And 41 cases only subject to UHS,64 cases only subject to electrotome.We observed the difference of operation time,blood loss of ALND,postoperative draining volume,duration of axillary draining and length of stay and postoperative complications.Results There was no significant difference in operating time,blood loss and length of stay between the two groups.However,the incidence of postoperative complications such as flap necrosis and postoperative rehaemorrhagia in UHS group was dramatically decreased as compared with electrotome group.Conclusion The therapeutic effect of UHS is better than that of elect rotome in modified radical mastectomy.
