HEPATIC RESECTION: VALUE OF OPERATIVE ULTRASOUND AND ULTRASONIC DISSECTION

Abstract

Twenty-five patients having a major liver resection at the Austin Hospital were reviewed, 18 of whom had their operation after 1986. The indications were for metastatic disease in 14, hydatid in six and primary tumour in five. There were no operative deaths. Dissection was performed with the Cavitron Ultrasound Surgical Aspirator (CUSA) and peroperative ultrasound used in 18 and without in seven. Mean blood loss was 1.75 u in the CUSA group and 6.5 u in the non-CUSA group (P less than 0.05). It is concluded that intra-operative ultrasound and use of the CUSA makes major liver resection a more precise and less hazardous procedure.
