Porta hepatis dissection, robotic pancreaticoduodenectomy

At the porta hepatis, remove the hepatic artery lymph node to identify the proper hepatic artery and gastroduodenal artery, dividing the gastroduodenal artery with a vascular stapler. If the hepatic artery node is not visualized, a safe location to start dissection is the anterior and left porta hepatis to find the hepatic artery at that location.
