Tips and tricks of surgical technique for pancreatic cancer: portal vein resection and reconstruction (with videos).

Surgical resection is the only hope for cure in patients with pancreatic cancer. To improve the resectability and achieve better prognosis of this lethal disease, extended resection for pancreatic cancer has been applied. We have performed portal vein resection aggressively for pancreatic cancer with portal vein invasion. We also established a method of portal vein reconstruction using the left renal vein graft for tumors widely extended to the portal vein. Our data show similar survival between patients with portal vein obstruction and those without invasion. We also show that portal vein reconstruction using the left renal vein graft can be performed safely without severe liver damage. With video, we introduce our surgical technique for portal vein resection and reconstruction, especially focusing on the usage of the left renal vein graft, providing several tips for a safe and successful procedure.
