What is the definition or description of: pancreas transplantation?

See below: Pancreas can be removed and cells separated to isolate the islet cell (help regulate sugar) and cells are then implanted into liver. Other possibility would be to take pancreas from a donor and transplant the entire organ into a patient ( this will then require immune suppression to avoid rejection).

A new pancreas: Organ transplantation is removing a healthy organ from a donor, and sewing it into the patient whose organ is not functioning. Pancreas transplantation is performed in type 1 diabetics because their pancreas cannot make insulin. Placing a new pancreas will cure the diabetes, but requires taking drugs to prevent rejection (immunosuppressive medications).

Pancreas transplant: Type 1 diabetics do not make insulin, but if they get a transplant, the new pancreas would make Insulin and the sugars would be normal. It is like having a biologic Insulin pump that works perfectly. It is not a cure, but it is currently the most effective treatment available. The downside: it involves a big operation, lifelong immunosuppresion and is only offered to select individuals.
