The healthy pancreas is taken from a donor who is brain dead, but is still on life support. The donor pancreas must be carefully matched to the patient who is receiving it. The healthy pancreas is transported in a cooled solution that preserves the organ for up to about 20 hours. The patient's diseased pancreas is not removed during the operation. The donor pancreas is usually placed in the right lower part of the patient's abdomen. Blood vessels from the new pancreas are attached to the patient's blood vessels. The donor duodenum is attached to the patient's intestine or bladder. The surgery for a pancreas transplant takes about 3 hours.
