Pancreas transplant

The pancreas is an organ tucked behind the lower part of your stomach. Among other jobs, it makes insulin the hormone that lets your body move sugar (glucose) out of the blood and into cells for energy. In type 1 diabetes, the immune system has destroyed the insulin-making cells, so the body cannot make insulin at all. People then rely on insulin injections or a pump to stay alive.

A pancreas transplant is an operation that places a healthy pancreas from a deceased donor into a person whose own pancreas no longer makes insulin. The new organ takes over insulin production. When it works well, many people no longer need to inject insulin and their blood sugar becomes far more stable.

Your own pancreas is almost always left in place. It still does useful work producing digestive enzymes, so surgeons do not remove it; they simply add the donor organ in the lower abdomen. Doctors sometimes describe a successful pancreas transplant as the closest thing we have to a cure for type 1 diabetes but it is major surgery and it comes with lifelong medication, so it is reserved for people who genuinely need it.

A pancreas transplant is not for most people with diabetes. The great majority manage well with insulin, modern pumps and continuous glucose monitors. Transplant is considered when diabetes is causing serious problems that other treatments cannot control, and when the benefit is judged worth the risks of surgery and lifelong immune-suppressing drugs.

You may be a candidate if you have:

• Insulin-treated diabetes (usually type 1) together with kidney failure such people are often offered a combined kidney-and-pancreas transplant.
• Type 1 diabetes with good kidney function but brittle blood sugar dangerous, repeated low-sugar (hypoglycaemic) episodes, especially hypoglycaemia unawareness, where you no longer feel the warning signs of a low before it becomes severe.
• A previous kidney transplant, and you now want freedom from insulin (a pancreas-after-kidney transplant).

A transplant may not be right if you:

• Are not well enough to come through a long operation for example, significant heart or lung disease.
• Have an active infection or untreated cancer.
• Would not be able to take powerful immune-suppressing medicines reliably for life, or cannot tolerate their side effects.

Most people with type 2 diabetes are not suitable, because their problem is usually how the body responds to insulin rather than a lack of it though a minority of carefully selected type 2 patients are considered. A full assessment weighs your heart, kidneys, blood vessels, dental and general health, and your readiness for lifelong follow-up.

There are three main types, and which one suits you depends mostly on your kidneys.

• Simultaneous pancreas-kidney (SPK) a new pancreas and a new kidney are transplanted in the same operation, usually from the same donor. This is the most common type, for people who have both diabetes and kidney failure. It tends to give the longest-lasting results because both organs are well matched and transplanted together.
• Pancreas-after-kidney (PAK) for someone who has already received a kidney transplant and later receives a pancreas, often around a year afterwards. It avoids one big operation but needs two separate procedures.
• Pancreas transplant alone (PTA) for people with good kidney function whose blood sugar is dangerously unstable. The aim is to stop severe lows rather than to treat kidney disease.

Surgical techniques. The donor pancreas comes with a small attached piece of the donor's first part of the small intestine (the duodenum). The pancreas makes digestive juices that have to drain somewhere, so the surgeon connects that piece either to your own intestine (called enteric drainage, now the usual choice) or, less often, to the bladder. The organ's blood vessels are joined to your blood vessels so it gets a blood supply. These technical choices affect how the team monitors the graft and which side effects are more likely.

You will be under general anaesthesia fully asleep and feeling nothing throughout. Before surgery the team places thin tubes (lines) into a vein in your neck and arm to give fluids and medicines, and a catheter into your bladder.

The main steps:

1. The surgeon makes an incision down the middle of the abdomen.
2. The donor pancreas is placed low in the abdomen, often on the right side. Your own pancreas stays where it is.
3. The donor organ's arteries and veins are stitched to your blood vessels so blood flows through it. Blood flow is briefly paused while these tiny connections are sewn.
4. The attached piece of donor intestine is joined to your intestine (or bladder) so digestive juices can drain.
5. If a kidney is being transplanted at the same time (SPK), the surgeon places and connects the new kidney too.
6. Small drainage tubes may be left in place temporarily, and the incision is closed.

How long it takes: a pancreas transplant on its own usually takes about 2-4 hours. A combined pancreas-and-kidney transplant takes longer often 4-8 hours or more. Many people start to make their own insulin within hours of the new pancreas being connected.

Recovery from a pancreas transplant is gradual. Patience matters this is big surgery, and the new organ needs time to settle.

• First days in hospital. You will be watched very closely, often in an intensive-care or high-dependency unit at first. The team checks blood sugar, blood tests for pancreas and kidney function, and how the wound is healing. Pain relief, fluids and the first doses of anti-rejection medicine are given. Hospital stays commonly run from a few days to a few weeks; many programmes report around 1-3 weeks, and stays are longer for combined transplants.
• Getting moving. Within a few days you will be encouraged to take short walks (5-10 minutes), building up slowly. Gentle movement lowers the risk of blood clots and chest infections.
• First weeks at home. Rest, avoid lifting anything heavy (over about 10 kg / 22 lb), and keep up short daily walks. Skin stitches or clips are often removed around 3 weeks.
• Six to twelve weeks. Many people can begin light exercise around 6 weeks and resume driving once they feel safe and have clearance. Returning to work is common around 3 months, depending on the job.
• Around six months. This is roughly when most people feel fully recovered.

Expect frequent clinic visits at first sometimes two or three times a week so the team can fine-tune your medicines and catch any problem early. Follow-up then spaces out but continues for life.

A pancreas transplant carries real risks, which is why it is offered only when the likely benefit outweighs them. Your team will explain how these apply to you.

• Blood clot in the new pancreas (thrombosis). This is the most common non-immune reason a graft fails, and it usually happens early. Reported rates vary widely. Surgeons watch closely for it in the first days.
• Rejection. Your immune system may try to attack the donor organ. Most rejection happens in the first 6 months. Warning signs can include fever, tenderness over the graft, or rising blood sugar. It is often treatable if caught early, which is why monitoring is so intensive.
• Infection. Anti-rejection drugs lower your defences, so infections (bacterial and viral, such as cytomegalovirus) are more likely, particularly in the first months.
• Inflammation of the graft (pancreatitis), leaks or bleeding. Because the pancreas produces digestive juices, leaks at the connection points and graft inflammation can occur and sometimes need further treatment or surgery.
• Side effects of immune-suppressing medicines. These can include increased appetite and weight gain, raised blood pressure, higher blood sugar, kidney strain, and over the long term a higher risk of certain cancers and infections.
• General surgical risks such as reaction to anaesthesia, wound problems and blood clots in the legs or lungs.

No surgeon can promise a particular outcome. A frank conversation about your personal risks is part of a good consultation.

When a pancreas transplant works, the rewards can be life-changing: many people stop needing insulin injections, their blood sugar steadies, and dangerous lows become far easier to manage. Even when some insulin is still needed, control is usually much better. Stopping the long-term harm diabetes does to nerves, eyes, kidneys and blood vessels is a major goal.

Survival after the operation is generally high published figures put one-year patient survival above 95%, and most people are alive at five years. How long the transplanted pancreas keeps working varies by type. Combined kidney-and-pancreas (SPK) grafts tend to last longest; a common rule of thumb is that roughly half of transplanted pancreases are still working well at five years, and many last considerably longer. Pancreas-alone and pancreas-after-kidney grafts, on average, do not last as long as SPK grafts.

Two things matter most for longevity: taking your anti-rejection medicines exactly as prescribed, and attending follow-up so problems are spotted early. These numbers are averages from large registries your own outlook depends on your health, your donor match and your transplant team.

A pancreas transplant is a major, resource-heavy operation, so the total cost reflects far more than the surgery itself. Because it involves a deceased-donor organ, intensive aftercare and lifelong medication, pricing is highly individual and is best confirmed in writing for your specific case rather than estimated from a generic figure.

What typically drives the price up or down:

• Type of transplant. A combined kidney-and-pancreas (SPK) operation is more involved than a pancreas alone, with a longer theatre time and recovery.
• Length of hospital and intensive-care stay, which depends on how smoothly you heal.
• Pre-transplant assessment the heart, kidney, infection and other tests needed before you can be listed.
• Complications, if any, that need extra treatment or a return to theatre.
• Immune-suppressing medicines and follow-up, which continue for life and add ongoing cost.
• Hospital, surgeon experience and city, and for international patients, travel, accommodation and interpreter or coordinator services.

Always ask for an itemised quote that states exactly what is and is not included for example whether assessment, donor-organ costs, intensive care, a set number of follow-up visits, and an allowance for complications are covered. A clear written breakdown is a sign of a trustworthy provider.

Turkiye has become a well-known destination for medical care, with a large number of internationally accredited hospitals, experienced transplant teams and dedicated international-patient departments offering English-speaking coordinators and help with logistics. For complex surgery like a transplant, though, choosing carefully matters far more than choosing quickly.

What to verify before you commit:

• Hospital accreditation. Look for recognised accreditation such as Joint Commission International (JCI), which signals that the hospital meets international standards for safety and quality.
• Surgeon and team credentials. Ask about the surgeon's board certification, their specific experience with pancreas (and kidney-pancreas) transplants, and the centre's annual transplant volume and outcomes. High-volume teams generally have more experience managing complications.
• Legal and ethical clarity. Organ transplantation is tightly regulated. Be sure the donor pathway is fully lawful and ethical, and that the hospital is transparent about how organs are sourced and allocated. Walk away from anyone who is vague about this.
• Aftercare and follow-up. A transplant needs lifelong monitoring. Confirm how follow-up will work once you go home, who manages your anti-rejection medicines, and how the Turkish team will communicate with your doctors at home.
• Clear written information. A reputable clinic gives you honest answers about risks, realistic outcomes, and an itemised cost no pressure, no guarantees of a cure.

Good preparation makes surgery safer and recovery smoother. Before being accepted, you will go through a thorough assessment blood and tissue typing, infection and cancer screening, and heart, lung and kidney tests to make sure a transplant is right for you and to find the best donor match.

To prepare:

• Bring a complete medical history, your current medicines, and recent test results.
• Follow advice on diabetes control, diet and stopping smoking; if you smoke, stopping helps healing and lowers complications.
• Arrange support for the weeks after surgery you will not be able to lift or drive at first.
• For travel abroad, plan for a long enough stay to cover surgery, early follow-up and the wait before it is safe to fly.

Useful questions to ask:

• Which type of transplant do you recommend for me, and why?
• How many of these operations does this team perform each year, and what are your outcomes?
• What are my personal risks given my health?
• What anti-rejection medicines will I take, and what side effects should I expect?
• How will follow-up and medication be handled after I return home?
• What does the quote include, and what happens to the cost if there are complications?
• How will the donor organ be sourced, and is the process fully lawful and ethical?

The transplant is only the beginning the rest of your life with a new pancreas depends on careful aftercare. You will take immunosuppressant (anti-rejection) medicines every day, for as long as the organ works, to stop your immune system attacking it. Missing doses is one of the main reasons grafts fail, so a reliable routine is essential.

Expect regular blood tests and clinic visits, frequent at first and then spaced out, to check that the pancreas (and kidney, if transplanted) is working and to adjust your medicines. Learn the warning signs of rejection and infection fever, tenderness over the graft, rising blood sugar, feeling generally unwell and know who to contact quickly if they appear.

When is it safe to fly? Major abdominal surgery and the early recovery period both raise the risk of blood clots (deep vein thrombosis), so flying too soon is unwise. Many guidelines suggest waiting until you are healing well and mobile often several weeks but for a transplant the timing must be set individually by your surgeon, who will also confirm your medicines and monitoring are stable enough for travel. When you do fly, reduce clot risk by moving your legs and ankles regularly, walking the cabin when you can, staying hydrated, and wearing compression stockings if advised.

If you travelled abroad for surgery, do not head home the moment you are discharged. Plan to stay long enough for early follow-up, and make sure there is a clear, written hand-over so your doctors at home can continue your care and prescribe your medicines without interruption.
