A pancreas transplant is an organ transplant that involves implanting a healthy pancreas (one that can produce insulin) into a person who has diabetes. Because the pancreas performs functions necessary in the digestion process, the recipient's native pancreas is left in place, and the donated pancreas attached in a different location. In the event of rejection of the new pancreas, the recipient could not survive without the native pancreas still in place. The healthy pancreas comes from a donor who has just died or it may be a partial pancreas from a living donor. [1] Whole pancreas transplants from living donors are not possible, again because the pancreas is a necessary organ for digestion. At present, pancreas transplants are usually performed in persons with insulin-dependent diabetes who have severe complications.

[edit] Types
There are three main types of pancreas transplantation:
- Simultaneous pancreas-kidney transplant (SPK), when the pancreas and kidney are transplanted simultaneously from the same deceased donor.
- Pancreas-after-kidney transplant (PAK), when a cadaveric, or deceased, donor pancreas transplant is performed after a previous, and different, living or deceased donor kidney transplant.
- Pancreas transplant alone, for the patient with type 1 diabetes who usually has severe, frequent hypoglycemia, but adequate kidney function.
[edit] Indications
In most cases, pancreas transplantation is performed on individuals with type 1 diabetes with end-stage renal disease The majority of pancreas transplantations (>90%) are simultaneous pancreas-kidney transplantions.[2]
[edit] Preservation until implantation
The donor's blood in the pancreatic tissue will be replaced by an ice-cold organ storage solution, such as UW (Viaspan) or HTK until the allograft pancreatic tissue is implanted.
[edit] Complications
Complications immediately after surgery include rejection, thrombosis, pancreatitis and infection.
[edit] Prognosis
The prognosis after pancreas transplantation is very good. Over the recent years, long-term success has improved and risks have decreased. One year after transplantation more than 95% of all patients are still alive and 80-85% of all pancreases are still functional. After transplantation patients need lifelong immunosuppression. Immunosuppression increases the risk for a number of different kinds of infection[3] and cancer.
[edit] History
The first pancreas transplantation was performed in 1966, three years after the first kidney transplantation.[4] A pancreas along with kidney and duodenum was transplanted into a 28-year-old woman and her blood sugar levels decreased immediately after transplantation, but eventually she died three months later from pulmonary embolism. In 1979 the first living-related partial pancreas transplantation was done.
