Pancreas transplantation
A pancreas transplant is an organ transplant that involves implanting a healthy pancreas (one that can produce insulin) into a person who usually has diabetes. Because the pancreas is a vital organ, performing functions necessary in the digestion process, the recipient's native pancreas is left in place, and the donated pancreas is attached in a different location. In the event of rejection of the new pancreas which would quickly cause life-threatening diabetes, 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.〔(Type 1 cures - pancreas transplants )〕 At present, pancreas transplants are usually performed in persons with insulin-dependent diabetes, who can develop severe complications. Patients with the most common- and deadliest- form of pancreatic cancer (pancreatic adenomas- which are usually always malignant, with a poor prognosis and high risk for metastasis- as opposed to more treatable pancreatic neuroendocrine tumors or pancreatic insulinomas) are usually not eligible for valuable pancreatic transplantations, since the condition usually has a very high mortality rate and the disease, which is usually highly malignant and detected too late to treat, could and probably would soon return.
==Medical uses==
In most cases, pancreas transplantation is performed on individuals with type 1 diabetes with end-stage renal disease, brittle diabetes and hypoglycaemia unawareness. The majority of pancreas transplantation (>90%) are simultaneous pancreas-kidney transplantation. It may also be performed as part of a kidney-pancreas transplantation.
