The following are the three types of pancreas transplants:

Simultaneous Pancreas and Kidney (SPK)
Patients with Type 1 Insulin-Dependent Diabetes who also have chronic kidney failure are eligible for a simultaneous pancreas and kidney transplant. These patients receive a kidney and a pancreas at the same time from a cadaveric donor (a donor who has passed away). This transplant means the patient no longer requires dialysis or insulin. The transplant takes five to eight hours for both organs to be transplanted and patients are hospitalized for up to two weeks.

Pancreas After Kidney (PAK)
An option for patients who need both a pancreas and kidney transplant is to receive a living kidney donor transplant and then, at a later date, get a pancreas transplant. To be a candidate for this transplant, patients must have Type I Insulin-Dependent Diabetes Mellitus and have had a previous kidney transplant.

Pancreas Transplant Alone (PTA)
PTAs are indicated for patients who have insulin dependent diabetes (type 1) without kidney disease. To be eligible for a PTA, candidates must be experiencing major difficulty in controlling glucose levels or experiencing other complications of diabetes. PTAs are the least common of the different pancreas transplants.
