Aim:
To evaluate the feasibility and safety of vacuum-assisted resection of benign breast tumours using an 8 G handheld device.
Materials And Methods:
Over a 2-year period, 22 patients with 26 breast tumours diagnosed as benign using aspiration biopsy cytology were enrolled. The mean patient age was 38 years, and the mean maximal diameter of the tumour was 13 mm. A handheld Aloka SSD 6500 ultrasonography device with a linear-type 7.5 MHz transducer was inserted into the posterior aspect of the tumour with the patient under local anaesthesia, and the tumour was resected under ultrasonographic guidance.
Results:
This method was employed successfully in all patients, and the mean operation time was 33 min. Post-procedure complications included subcutaneous bleeding in 12 cases and haematoma in one. The pathological diagnoses were fibroadenoma in 16 cases, mastopathy in six, and tubular adenoma and pseudoangiomatous stromal hyperplasia in two cases each, respectively. Follow-up ultrasonography revealed residual tumours in four cases (15.4%).
Conclusions:
Although this method is feasible and safe without severe complications, it is necessary to select appropriate patients, and to obtain informed consent regarding the possibility of recurrence or residual tumour.
