Margin-free excision of small solid breast carcinomas using the Intact Breast Lesion Excision System: is it feasible?

Background: The Breast Lesion Excision System (BLES) is a stereotactic vacuum-assisted breast biopsy device that utilizes radiofrequency in order to excise non-palpable mammographic lesions for pathologic diagnosis. The purpose of this study was to evaluate the efficacy of BLES in performing complete, margin-free excisions of small solid carcinomas.

Methods: Our retrospective study of prospectively enrolled patients included 50 cases of non-palpable, BIRADS ≥ 4, solid by means of mammography and sonography, lesions.

Thermal damage of the specimen during breast biopsy with the use of the Breast Lesion Excision System: does it affect diagnosis?

Background: Stereotactic vacuum assisted breast biopsy (VABB) procedures remain of key importance in the diagnostic evaluation of suspicious non-palpable mammographic lesions. The Breast Lesion Excision System(®) (BLES) is an image-guided percutaneous biopsy method that utilizes radiofrequency (RF) in order to retrieve an intact-tissue biopsy specimen. The purpose of this study is to determine the effects of RF application on the tissue specimen and the possible interference with the histopathologic results.

Complications of percutaneous stereotactic vacuum assisted breast biopsy system utilizing radio frequency.

Objective: The Breast Lesion Excision System (BLES) is a novel, automatic breast biopsy device that utilizes radiofrequency to excise suspicious non-palpable mammographic lesions. The purpose of the present prospective study is to report and evaluate the complications of this new technique.

Materials And Methods: In a two year period, we used the BLES device in 132 consecutive patients (134 procedures) with non-palpable mammographic lesions.
