Use of intraoperative ultrasound during hepatic resection in pediatric patients

Abstract

Five pediatric patients with primary liver tumors were evaluated preoperatively with ultrasound (US), computerized tomography (CT), and angiography, and tentative operative plans were formulated. Intraoperative US was subsequently used to examine these children, resulting in changes in operative strategy of all five patients despite their extensive preoperative evaluations. Intraoperative ultrasound appears to provide the most accurate assessment of both the extent of tumor and its vascular relationships. Thus, operative strategies may be precisely tailored on the basis of such information, allowing rational resection where appropriate, while futile attempts at removal of inoperable lesions may be averted.
