OBJECTIVE: BLES (Intact Breast lesion Excision System) is a new defined system which can remove the lesion completely. We aimed to evaluate and compare the results of BLES used for breast lesions requiring histological verification with other percutaneous biopsy methods in the literature. METHODS: Patients with breast lesions smaller than 20mm and for whom biopsy was indicated were involved in the study. 18(1 male, 17 female, mean age: 41. 83, age range: 26-72) patients were included the study. BLES is applied with a single insertion. Radiofrequency is used to excise the breast tissue after the insertion. Around the lesion, tissue capture basket is moved back and forth. Once captured, the basket and the probe is removed from the incision area. RESULTS: All of the lesions were excised en-bloc. The only complication occured was subdermal hematoma in one case (5.5%) which resolved spontenously. Pathological analysis of the specimens revealed 9 fibroadenoma, 3 fibroadenomatosis hyperplasia, 3 complicated and calcified cysts, 1 ductal epithelial hyperplasia, 1 carcinoma in situ with intraductal papillary carcinoma focus and 1 ductal carcinoma in situ with 2 mm invasive carcinoma focus. The last two cases underwent resectıon and sentınal lymph node procedure. CONCLUSION: BLES is a is non-invasive method which has no need for additional initiatives in benign cases, provide sufficient samples for pathological diagnosis and remove the lesion in one piece. BLES method can be applied in selected cases.
