Preoperative three-dimensional simulation for liver resection

Abstract

Precise understanding of each patient’s anatomy is crucial in hepatobiliary and pancreatic surgery, especially in liver resection. We have long been using simulation software SYNAPCE VINCENT^® to calculate graft volume and remnant liver volume in living donor hepatectomy. More recently, we introduced preoperative three-dimensional fusion imaging, which allows excellent visualization of the complex conformation of the hilar structures and major hepatic veins and their tributaries. We also applied this technique for hepatic tumors to understand the relation between the intrahepatic vasculature and lesion. Herein, we demonstrate our technique in living donor hepatectomy and liver tumor resection in our department.
