Due to the rich lymphatic network in the axilla it is necessary to carefully dissect and identify all lymphatic channels. Traditionally these lymphatics are sealed with titanium clips or individually sutured. Recently the Harmonic Focus a hand-held ultrasonic dissector allows lymphatics to be sealed without the utilization of clips or ties. We hypothesize that ALND performed with the Harmonic Focus will decrease operative time and reduce post-operative complications. Methods Retrospective review identified all patients who underwent ALND at a teaching hospital between January of 2005 and December of 2009. Patient demographics presenting pathology treatment course operative time days to drain removal and surgical complications were recorded. Comparisons were made to a selected control group of patients who underwent similar surgical procedures along with an ALND performed utilizing hemostatic clips and electrocautery. A total of 41 patients were included in this study. Results Operative time was not improved with the use of ultrasonic dissection however there was a decrease in the total number of days that closed suction drainage was required although this was not statistically significant. Complication rates were similar between the two groups. Conclusion In this case-matched retrospective review there were fewer required days of closed suction drainage when ALND was performed with ultrasonic dissection versus clips and electrocautery.
