    Abstract:
    BACKGROUND AND AIM: There is still controversy on the outcomes of portal vein (PV) and/or superior mesenteric vein (SMV) resection in pancreatic cancer, and there are few reports about pancreaticoduodenectomy (PD) with PV/SMV resection and reconstruction by using allogeneic vein. This study is to explore the outcomes of PD with PV/SMV resection and reconstruction by using allogeneic vein for pT3 pancreatic cancer with venous invasion. METHODS: Clinicopathological data of patients underwent PD with en bloc resection of PV/SMV and reconstruction by using internal iliac from August 20, 2013 to July 25, 2015 were collected and the data of patients with pT3 stage pancreatic head cancer with PV/SMV invasion were analyzed. The short- and long-term outcomes were presented. RESULTS: Thirty patients met the criteria of this study. PV resection and reconstruction were performed for 12 patients, SMV for 9 patients, and PV + SMV for 9 patients, respectively. The median operation time was 460 min, and the median intraoperative blood loss was 450 mL. R0 resection rate was 93.3%, total incidence of complications was 23.3%, and incidence of pancreatic fistula was 10%. The 1-year and 2-year overall survival rates were 68.6% and 39.2%, 1-year and 2-year disease free survival rates were 44.8% and 17.1%. CONCLUSIONS: PD with en bloc resection of PV/SMV and reconstruction by using allogeneic vein was safe and feasible for patients with pT3 stage pancreatic head cancer with PV/SMV invasion. A large-scale research with longer follow-up time is required to draw a significant conclusion.
