Islet cells are the cells in the pancreas that make insulin. Pancreatic islet cell transplantation is the transfer of islet cells from a donor to another person. The procedure is being studied as a method to treat chronic pancreatitis or type 1 diabetes .

What to Expect
Prior to Procedure
Your doctor will order blood tests. A physical exam will be done. These tests will assess the extent and severity of diabetic complications. This includes damage to the kidneys. The donor must also be carefully screened for blood and serum matching.
Local or general anesthesia may be used. Local will numb the area. You will be asleep with general anesthesia.
Description of Procedure
Before surgery, islet cells are removed from one or more donor pancreases. Usually, these cells are used within the next 24 hours.
A small incision will be made in the abdomen. A catheter (small plastic tube) will be placed through the incision and into a major blood vessel of the liver. An ultrasound will be used to locate the right position. Islets cells will be injected through the catheter. The cells travel through the vein and attach to the liver. There, they will begin making insulin.
Immediately After Procedure
It is important to maintain a normal blood glucose level. A high blood glucose could damage the new islet cells. Insulin will be given through an IV for the first several days. This will help keep your blood glucose levels down.
Your immune system will attack the transferred cells. To prevent this type of attack, called early acute rejection, you will be given medicines to suppress your immune system.
Similar medicines to suppress the immune system are usually needed for the rest of the person’s life to prevent rejection.
How Long Will It Take?
About one hour
How Much Will It Hurt?
The injection of local anesthetic may sting or burn. Anesthesia will prevent pain during the procedure. After the procedure, some patients experience pain or soreness for a few days. If you have discomfort, ask your doctor about pain medicine.
Average Hospital Stay
- Keep the incision wound clean.
- Follow your doctor’s instructions about wound care.
- Check your blood glucose frequently. Follow your doctor’s instructions.
- Closely control blood sugar levels with insulin.
Your doctor may repeat the process several times to transfer more islet cells.
