ABSTRACT

Background: Diverse instruments exist to locate non-palpable breast lesions, among which stand out different types of needles, the one hook-wire (Sadowsky, Kopans) or with double hook-wire (Bard Dualok). The correct location of these markers in a non-palpable lesion requires a more experienced radiologist and surgeon. Also, sometimes they can be accidentally displaced from the site where the lesion is located.
Objective: To evaluate a new instrument (designed by the authors) to locate non palpable breast lesion, in which malignancy is suspected.Patients, material and methods: This is a prospective, observational and randomized study. The variables that were considered are: fixation, less surgical time, bleeding and amount of tissue necessary for the complete excision of the lesion.
Results: 58 women were included with a diagnosis of non palpable breast lesion. In group A, we used the traditional gauge needle, in group B we used the new instrument which was used to localize the lesion, and in group C, the activated carbon technique was used. In group A, the average quantity (ml) of the excised tissue was 42.29 (±35.47), in group B, it was 20.00 (±18.48) and in group C, it was 111.10 (±115.20). There was no statistical difference in surgical time (p ‹0,001). There was minor bleeding in group A, around 14.17 ml (±4.82). More fixation was found in group B, around 266 gr, (±69.23).
Conclusions: The new instrument to locate non palpable breast lesions has better fixation, this allows knowing with more accuracy and precision the site of the lesion, which facilitates its excision.
