ABSTRACT
The majority of the pancreatic cancer was diagnosed at advanced stage.The tumor may invade portal vein and/or superior mesenteric vein.Moore et al.firstly reported pancreaticoduodenectomy combined with portal vein and superior mesenteric vein resection and reconstruction in 1951.This procedure has improved the resection rate of pancreatic cancer.A 72-year-old man suffered from pancreatic cancer was admitted to the Southwest Hospital in September 2011.Because the tumor invaded the confluence of portal vein and superior mesenteric vein,thus the patient underwent a pancreaticoduodenectomy combined with portal vein and superior mesenteric vein resection and reconstruction.The patient recovered smoothly without any complication,and he had a normal liver function and CA19-9 value,and no local and remote metastasis was detected during the follow-up.
