Extent of dissection in the hepatic hilum in right trisectionectomy.
1 The right hepatic artery and the artery to segment IV are separated. 2 The ductus choledochus (main bile duct) is suprapancreatically cut and the left hepatic duct is separated in the umbilical fissure near the branch to segments 2 or 3. 3 Resecting the fork of the portal vein provides a wider safety margin to the tumor. The authors thank their colleague, Dr Gumpp, for preparing this graph.
