resectional techniques and tools. A new high velocity water jet dissector is reported which offers
significant advances over previously developed ultrasonic and low pressure water jet machines. It has
been successfully used in 8 major hepatic resections with minimal blood loss, excellent visibility and
without complications. The dissector is also of value in the exposure of intrahepatic bile ducts for biliaryenteric
anastomosis.</p>
