Intraoperative Ultrasound-Guided Excision of Nonpalpable Breast Lesions

The methods commonly used to guide surgical excision of impalpable breast lesions include preoperative placement of hookwires, carbon injections, and, more recently, radioisotope injections. However, all of these techniques have disadvantages, not the least of which is subjecting the patient to an additional stressful and often traumatic procedure preoperatively. The use of intraoperative ultrasound to guide the excision of sonographically visible impalpable lesions is a new technique that avoids the need for a preoperative localization procedure. This report describes one of the author’s (I.B.) personal series of ultrasound-guided breast excisions, collating data collected prospectively, and reviews the efficacy of this technique. Data in relation to 115 ultrasound guided breast excisions performed in 103 patients were reviewed. The technique of using a high-frequency real-time ultrasound probe intraoperatively to localize and guide excision of breast abnormalities is described. There were no failed excisions, as confirmed by specimen sonography, pathology findings, and/or follow-up ultrasound. Breast malignancies comprised 42% of all excised lesions, and of these, adequate margins of excision were achieved at the first operation in 93% of cases. Direct ultrasound localization of the lesion at the time of surgery allowed optimal placement of the incision and eliminated delays in operating time because specimens did not have to be sent to the Radiology Department for confirmation of excision. Intraoperative ultrasound-guided excision is a safe and efficient technique in the management of impalpable, sonographically visible breast lesions, and early reports in the world literature support the findings of this series, which show it to have significant advantages over other current methods, particularly with respect to a reduction in patient anxiety and improved surgical resection margins.
