A novel modality for intraoperative margin assessment and its impact on re-excision rates in breast conserving surgery.

Background: A single center retrospective chart review was performed examining the ability of a novel radiofrequency probe (Margin Probe; Dune Medical Devices, Caesarea, Israel) for intraoperative margin assessment to reduce the number of reexcisions in breast-conserving surgery.

Methods: Reexcision rates were evaluated in one-hundred and twenty consecutive patients before and after the institution of the device. Utility of the device was evaluated by comparing intraoperative feedback with postoperative pathology reports.
