Surgical drainage of lactational breast abscess with ultrasound-guided Encor vacuum-assisted breast biopsy system.

Lactational breast abscess is a serious complication of mastitis and commonly diagnosed in breast-feeding women. The traditional drainage of breast abscess was often performed with incisive technique which may result in prolonged healing time, regular dressings, dressing pain, interfering with breastfeeding and unsatisfactory cosmetic outcome. As minimal invasive alternatives to incisive drainage, needle aspiration or percutaneous catheter placement cannot completely replace incisive drainage for the inability to treat large, multiloculated or chronic abscess. Vacuum-assisted breast biopsy system (VABB) has been successfully applied in the treatment of benign breast diseases with satisfactory cosmetic outcomes. Among VABB devices, EnCor system has some distinctive features that make it an appropriate candidate for the treatment of lactational breast abscesses. In this study, for the first time, we investigated the feasibility, efficacy, and cosmetic results of surgical drainage of lactational breast abscess with US-guided Encor VABB system. Our data suggests this procedure could serve as a promising alternative for women with lactational breast abscess who require incisive intervention with high cure rate, relatively short healing time, low recurrence rate, few complications, satisfactory cosmetics outcome and without interfering with breastfeeding.
