OBJECTIVE: The Advanced Breast Biopsy Instrumentation (ABBI) device (United States Surgical; Norwalk, CT) is designed to percutaneously excise nonpalpable breast lesions. Because this is a new technique, we report our initial experience with regard to technical success, complications, and histologic margins for malignancies. SUBJECTS AND METHODS: From May 14, 1997, until March 4, 1998, 89 consecutive patients elected to undergo the ABBI procedure. Preprocedure imaging included screening mammography and additional mammographic and sonographic studies when deemed necessary. Lesions were targeted by the surgeons. Specimen radiography was performed for all lesions, and the images were interpreted by radiologists. Pathologic analysis was provided or reviewed by a dedicated breast pathologist. Parameters analyzed included technical success, complications, lesion size, histologic diagnosis, and margin status for malignant lesions. RESULTS: There were 29 patients with 30 noncalcified masses, 53 patients with clustered calcifications, three patients with masses and calcifications, three patients with asymmetric densities, and one patient with architectural distortion. Eighteen ABBI procedures were aborted, converted to core biopsy, or failed to remove the targeted lesion. Fifteen patients experienced a total of 19 complications; 10 of the complications required treatment and follow-up after the biopsy. Of 11 malignant tumors revealed by ABBI, four had negative margins. Seven of these 11 malignant tumors had positive margins. CONCLUSION: The ABBI procedure had a high number of complications and technical failures and did not reliably provide cancer-free margins for malignant tumors. Women with nonpalpable breast lesions that need a tissue diagnosis are better treated by stereotactic or sonographically guided needle biopsy.
