title: [The Advanced Breast Biopsy Instrumentation (ABBI), a system for stereotactic excision of mammographically suspect nonpalpable findings in the breast].
abstract: Advanced Breast Biopsy Instrumentation (ABBI) allows radiologically guided stereotactic excision of non-palpable radiodense lesions with high accuracy. Tissue cylinders of 5, 10, 15 or 20 mm diameter and of variable lengths can be removed very accurately under local anaesthesia and on an outpatient basis. Thirty-six patients with suspicious clusters of microcalcifications (n = 29) and with round lesions (n = 7) of the breast were qualified for ABBI. We were able to perform the excisional biopsy in a total of 34 patients. The breast of one woman was too small to safely fit into the system and in another woman the lesion could not be visualized by the system. In 2/34 cases (6%), the excision was imprecise due to slight dislocation of the breast parenchyma by the advancing cylinder knife. In one case (3%), ABBI missed the target within a dense mastopathic breast. In all cases the excisions were well tolerated. No wound complications occurred and the cosmetic result was excellent. Histology revealed 28 benign (82%) and 6 malignant (18%) lesions. Among the 27 small microcalcifications there were 3 invasive carcinomas, 3 ductal carcinomas in situ (DCIS), 1 lobular hyperplasia, 14 mastopathies, 1 fibroadenoma, 1 duct papilloma and 4 calcifications in scars. Four of the 7 round-shaped lesions were found to be fibroadenomas, 1 lobular hyperplasia, and 2 mastopathies. With the ABBI system, non-palpable breast lesions can be precisely localized and excised.
