[A new technic of hepatectomy using peroperative echography and intraparenchymatous guide needles. The geometer technic].
A new technique of hepatectomy is described, using intra operative ultrasound and dental cleaner needle. The needle is inserted in the liver under ultrasonographic guidance, in order to mark the vessel which feed the tumor. Then the trans-section of the liver begins near the needle and the contact of its hip allows an elective ligation of the vessel. Thus the hepatectomy is performed safely along the ischaemic line of the subsegment bearing the tumor. The needle have been also used to mark the adjacent segmental portal vein and the hepatic vein which have to be secured during the operation. We have done 12 hepatectomies in cirrhotic patients with this technic without any complication.
