Needle-localised biopsy of impalpable breast lesions: a novel adjunct to surgical technique and specimen mammography.

Successful screening programmes have resulted in the more frequent detection of early impalpable breast tumours. Effective surgical management of impalpable lesions demands a precise approach to excision which is currently aided by radiologically guided needle-localisation of the lesion prior to operative removal. The surgical specimen procured is most commonly evaluated for tumour presence by specimen mammography intra-operatively or by histological analysis. The latter is more accurate but requires lengthy laboratory processing, which may result in re-operation if the primary excision is inadequate. Although advocated as the standard of care, specimen mammography remains an imperfect technique. In this article we describe a piece of surgical apparatus which attempts to address some of the concerns associated with specimen mammography. It is an inexpensive compression device which reduces operative time, avoids portable fluoroscopy, increased radiation and the necessity for specialised equipment
