Abstract:

Objective

To evaluate the clinical application of B-ultrasound-guided minimally invasive Mammotome (8-G) biopsy system in diagnosis and treatment of nonpalpable breast lesions.

Methods

Bultrasound-guided minimally invasive Mammotome biopsy system was performed for 96 nonpalpable breast lesions of 58 patients.

Results

The 96 breast lesions of the 58 patients were excised completely by Mammotome system and all operations were visualized by B-ultrasound . Clinically suspicious lesions were satisfactorily confirmed by this system. Seventy-six lesions were diagnosed as fibroadenoma, 16 lesions as breast adenosis, 1 lesion as intraductal papilloma,2 lesions as breast cancer, and 1 lesion as ductal carcinoma in situ. Skin ecchymosis was found in 3 patients after operation. The average excision time was 12 minutes (rainging 2 -45 times), and the average duration of operation was 15 minutes (3 - 47 minutes).

Conclusions

The B-ultrasound-guided Mammotome (8 G) system can be used to diagnose and treat nonpalpable breast lesions,for it is convenient,safe and minimally invasive. It is a choice for total resection of nonpalpable breast lesions. A determinative histopathologic diagnosis can be obtained even for suspected lesions by using this technique.
