Evaluation of a Biopsy Gun for Guided Biopsy of Impalpable Liver Lesions Using Intraoperative Utrasound

摘要

A biopsy gun which can be operated by one hand has been evaluated at post-mortem to determine itsaccuracy in biopsying impalpable lesions within the liver under intraoperative ultrasound control. Of 20impalpable metastases identified positive histology was obtained in 90% demonstrating that thistechnique is of value in identifying and localising metastases in the liver.
