    Abstract:
    OBJECTIVE: To establish a pig model of pancreaticoduodenal transplantation with jejunum drainage and portal venous drainage. METHODS: Forty pigs were randomly divided into the donor group and recipient group. University of Wisconsin (UW) solution was used for both in situ flush and storage of all organs under cold storage conditions. Whole pancreaticoduodenal graft was harvested with segments of abdominal aorta and portal vein and shaped under cold UW solution. Then, the end-to-end anastomosis was performed with the donor iliac artery bifurcation Y graft to the recipient superior mesenteric arteries and celiac artery. Furthermore, type I diabetes model was made by removal of the recipient pancreas The venous anastomosis was reconstructed between the donor portal vein and the recipient superior mesenteric vein. Meanwhile, the end-to-side anastomosis was performed with the donor common iliac artery bifurcation Y graft to the recipient abdomial aorta, and the side-to-side intestinal anastomosis between the donor duodenum and the recipient jejunum was performed. RESULTS: Twenty piges were subjected to pancreaticoduodenal transplantation, in which 1 died from respiratory depression because of anesthesia, and 2 had thrombus and infarction in the pancreatic graft after transplantation. 17 cases showed normal blood sugar in peripheral circulation 24 hours after operation, the mean survival of the graft was 18.6 +/- 2.6 days. CONCLUSION: The technique of duodenal transplantation with jejunum drainage and portal venous drainage may pave the way for the further development of pancreas transplantation in clinical practice. It can be utilized in basic research of pancreas transplantation.
