A New Technique of Minimally Invasive Excision and(or) Biopsy of Breast Masses——Mammotome Operation

【Abstract】ObjectiveTo introduce the minimally invasive excision and biopsy of breast neoplasm with Mammotome vacuum device guided by ultrasound. MethodsFiftytwo breast masses were detected in 30 patients through color Doppler. The ages of these patients range from 18 years to 49 years. Forty-six of those masses (88.5%) were clinically impalpable. Complete excision and biopsy of 52 breast masses were performed using Mammotome vacuum device guided by ultrasound. The patients were followed up and their postoperative condition were recorded. ResultsFiftytwo breast masses of 30 cases were excised completely, which was verified by color Doppler.The tissue excised by Mammotome were enough for pathological examination. Fortysix masses were proved to be fibroadenoma and the other 6 were proved to be adenosis. Hematoma was found in four patients after operation. The incisions were small and hidden, and the appearance of breasts remained well. Twenty patients were followed up for a shot period of time and no residual nidus or recurrence of the mass was found.ConclusionMinimally invasive excision and biopsy of breast masses with Mammotome vacuum device is an accurate and safe method. It is an ideal minimally invasive operation in treating benign breast neoplasm with few complications. It can be applied to biopsy of breast masses and complete excision of benign breast masses which are less than 2 cm in the same time.
