초음파 유도하 대구경 생검침을 이용한 Mammotome 생검술의 유용성

Abstract

요 약 초음파 유도하 대구경 8-gauge 생검침을 사용한 Mammotome 생검은 안전한 시술이며 특별한 합병증은 없었다. 초음파 검사상 양성 유방 결절이 의심되는 경우 조직학적 진단뿐만 아니라 치료를 동시에 시행할 수 있으며, 군집성 미세석회화가 초음파에 보이는 경우 악성과 양성의 감별뿐만 아니라 관피내암과 침윤성 관상피암의 구별이 가능하여 향후 치료방침의 결정에 많은 도움을 줄 수 있을 것으로 사료된다.

The purpose of this study is to evaluate the clinical usefulness of ultrasonography (US)-guided Mammotome biopsy by a new large 8-gauge biopsy probe. Seventeen cases were included in this study: 14 cases of ultrasonically benign-looking nodules of breasts and three cases of entensive m icrocalci fications by film mammography. We analyzed the safety and patient acceptance of Mammotome biopsy and the results of short-term follow-up US study. Pathological results of breast nodules revealed 12 cases of fibroadenoma and two cases of fibrocystic change, and the results of microcalcifications showed two cases of invasive ductal carcinoma and one case of ductal carcinoma in situ. We removed the targeted nodule completely in 9 cases (64%). Adverse events included mild-to-moderate pain during or after biopsy, ecchymosis, and some bleeding. Patient satisfaction and acceptance were high. Concerning short-term follow-up US study, there were four cases of hematoma (24%). We conclude that US- guided Mammotome biopsy using a large 8-gauge biopsy probe is feasible and safe diagnostic modality. This procedure would be diagnostic as well as therapeutic in the management of breast nodules and in the evaluation of mammographically visible extensive microcalcifications.
