The NHS Organ Donor Register

In the UK, consent is required before organs can be donated. A person can give their consent by joining the NHS Organ Donor Register or by discussing their wishes with loved ones.  

Many of us have heard of donor cards. The NHS Organ Donor Register is the same in principle but is a failsafe way of ensuring your wishes are made clear. Joining the register means there's a permanent record of your wishes that doctors can check in the event of your death.

Joining the NHS Organ Donor Register is quick, simple and you can remove yourself from it at any time.

Having an operation

If your GP has suggested you may need surgery, this guide is for you

A pancreas transplant is a surgical procedure to provide a new source of insulin in the form of a new pancreas for a patient with type 1 diabetes.

Most pancreas transplants are performed on people with type 1 diabetes who have kidney failure. The pancreas transplant is performed at the same time as a kidney transplant.

Pancreas transplants are also given to diabetic patients who don’t need a kidney, but who have life-threatening hypoglycaemic attacks. Hypoglycaemic attacks are a serious complication of diabetes caused by low levels of glucose in the blood. About one in 10 pancreas transplants are carried out for this reason.

Pancreas transplantation is less common than kidney or liver transplantation, and each year around 200 transplants are performed in the UK.

It is estimated that there are just over 300 people in the UK on the waiting list for a transplant. The waiting time for a pancreas transplant is between one and two years because there is a shortage of suitable donor organs.

The pancreas and type 1 diabetes

The pancreas is a tadpole-shaped organ, around 10–15cm long that is located in the top half of the abdomen.

The pancreas has two main functions:

  • it produces juices which the body uses to digest fats and proteins
  • it produces the hormone insulin which the body needs to break down glucose into energy

In cases of type 1 diabetes the pancreas does not produce any insulin because the insulin-producing cells, the islets, have been destroyed by the patient's own immune system.

Most people with type 1 diabetes are able to control the condition with regular injections of insulin. However, a small number of people go on to develop serious complications despite being given the best available treatment, such as:

  • end stage kidney disease – when the kidneys are no longer able to filter waste products from the blood
  • diabetic retinopathy – where high levels of glucose in the blood causes damage to the eyes, which can lead to loss of vision 
  • diabetic neuropathy – where high sugar levels have damaged the nerves in the hands and feet, meaning that sensation is lost and ulcers can occur
  • arterial disease – which affects the arteries to the heart and brain

A pancreas transplant is often combined with a kidney transplant to reduce progression of the complications of diabetes.

What happens during a pancreas transplant

A pancreas transplant can be carried out in three ways:

  • Simultaneous pancreas–kidney transplant (SPK) – both the pancreas and kidneys are transplanted. This is the most common type, accounting for nine out of 10 transplants. It is used in people who have kidney disease as a result of type 1 diabetes.
  • Pancreas-after-kidney transplant – a person first receives a kidney transplant from a living donor. This is then followed by a pancreas transplant from a recently deceased donor.
  • Pancreas-alone transplant – only the pancreas is transplanted. This is a treatment for patients with very poorly controlled type 1 diabetes who have hypoglycaemic attacks without warning, and which may threaten their life.

A pancreas transplant is a complicated operation and, like other types of major surgery, there is a risk of complications. 

About one person in four needs further surgery in the first few days after transplantation to deal with problems such as infection and bleeding.

There is also the risk of rejection. This is when the immune system (the body’s defence against infection) thinks the transplanted pancreas is a foreign body and attacks it.

To prevent rejection a type of medication is given to suppress the immune system (immunosuppressants). These need to be taken for the rest of the person's life.

Long-term use of immunosuppressants carries its own risk of complications, such as increased vulnerability to infection and cancer.

Having a pancreas transplant places a huge strain on the body and typically patients are in hospital for two to three weeks. 

Someone who has had a pancreas transplant can normally carry out their usual activities after a few months.

The outlook for people with a pancreas transplant, especially an SPK type of transplant, is relatively good.

On average a transplanted pancreas functions properly for 10 years.
