We designed and performed on two patients a new surgical procedure of en bloc kidney and pancreatic transplantation. The liver, pancreas and kidneys were removed en bloc in the donor. On the bench, the liver and the left kidney were separated from the bloc, leaving the pancreas and the right kidney for combined kidney and pancreatic transplantation. The portal vein was divided near to the emergence of the splenic vein. The coeliac axis was taken with an aortic patch. The left renal vein was cut at its entrance to the inferior vena cava (IVC) and the left renal artery was taken with an aortic patch. Reconstruction of the pancreatic vessels was performed with a double anastomosis: the portal vein was anastomosed to the hole in the IVC resulting from the section of the left renal vein and the splenic artery was anastomosed to the hole in the aorta resulting from the section of the left renal artery. The proximal ends of the aorta and IVC were closed with running sutures. In the recipient, the iliac vessels on the right side were dissected. Anastomosis of the distal part of the aorta and the IVC was performed with the right iliac vessels. Duodenocystostomy and reimplantation of the ureter were done according to the usual techniques. This new surgical technique allowed an easy vascular reconstruction of the pancreatic vessels. In the recipient, only one side was used for renal and pancreatic transplantation. Moreover, the length of the transplant procedure was significantly reduced.
