Ultrasonic surgical aspiration for gynecologic disease.
Ultrasonic Surgical Aspiration (USA) is a technique which employs a hand-held instrument that selectively
fragments and aspirates tissues of high-water content. The selectivity of the device permits
preservation of underlying vital structures while the aspiration provides a tissue specimen for histologic
analysis. Application of this device to neoplastic disease of the lower genital tract has been reported to
provide durable success rates of 78% for conyloma acuminata and vulvar intraepithelial neoplasia (VIN) and
81% for vaginal intraepithelial neoplasia (VAIN).Employment of USA in patients with advanced ovarian cancer
has been shown to improve surgical cytoreduction without increasing blood loss or complication rates.
