[Nonpalpable lesions of the breast. A new technique of ultrasound-guided excision biopsy].

The authors have developed a simple and accurate technique of excisional biopsy for non-palpable breast nodes using an intraoperative sonographic technique. Identification, localization and exeresis of the lesions are guided by means of a sterilized transducer introduced through the surgical wound. The confirmation of the correct biopsy is evaluated by scanning the specimen gowned with a surgical glove and comparing the intra- and postoperative ultrasonographic images. The results of analysis showed that in all cases the altered area was removed with extreme accuracy and the ultrasonography is reliable in identifying pathological or suspicious areas since the dimensions of the lesion measured with the scanner correspond significantly to the dimensions of the lesions when measured histologically.
