Late Shoulder-Arm Morbidity Using Ultrasound Scalpel in Axillary Dissection for Breast Cancer: A Retrospective Analysis.

BACKGROUND

We aimed to assess whether the use of the harmonic scalpel (HS) in axillary dissection would reduce long-term shoulder-arm morbidity compared to traditional instruments (TIs).

MATERIALS AND

METHODS

A retrospective analysis on 180 patients who underwent standard axillary dissection for breast cancer between 2007 and 2015 was carried out. All patients were evaluated for postoperative pain, impairment of shoulder-arm mobility, seroma formation in axilla, frozen shoulder, and lymphedema.

RESULTS

HS procedure on average was 50% shorter compared to the TI technique. HS reduced by 4.5 times the risk of axillary seroma. TIs were associated with 4 times higher risk of developing a painful frozen shoulder.

CONCLUSIONS

Use of the HS was associated with reduced costs and a positive long-term effect on shoulder-arm morbidity. Axillary seromas are not the only reason of later postoperative shoulder-arm morbidity: other mechanisms are hypothesized in the onset of this very disabling disorder.
