Should needle localization breast biopsy give way to the new technology; the advanced breast biopsy instrumentation.
Between July 1995 and June 1997, 114 consecutive women underwent 118 breast biopsies for nonpalpable lesions. A limited procedure room and local anesthesia were used in 96.5 per cent of patients. Intravenous access was not established in 95 per cent of patients. Oral diazepam was given to 51 per cent of patients. Needle localization technique was used with a success rate of 97.5 per cent and average operative time of 18 minutes. Breast carcinoma was found in 29 (24.6 per cent) biopsies. A review of 99 of the 118 mammograms showed only 45 per cent of the lesions being amenable to the new technology, the advanced breast biopsy instrumentation. Advantages of the needle localization include short operative time; supine position for the patient; easy access to control bleeding; ability to choose a cosmetic site for the skin incision; minimal tissue removal before reaching the lesion; ability to maintain a sterile field; and applicability to almost any mammographic lesion identified, whether single or multiple. Disadvantages include the need for a separate procedure to place the wire and potential of missing the lesion in 2.5 per cent, requiring additional surgery.
