Spleen problems and spleen removal
Find out NHS information on spleen problems, splenectomy and living without a spleen.
Spleen problems and spleen removalSome people are born without a spleen or need to have it removed because of illness or injury.
The spleen is a fist-sized organ in the upper left side of your abdomen, next to your stomach and behind your left ribs.
It's an important part of your immune system, but you can survive without it. This is because the liver can take over many of the spleen's functions.
What does the spleen do?
The spleen has some important functions:
it fights invading germs in the blood (the spleen contains infection-fighting white blood cells)
it controls the level of blood cells (white blood cells, red blood cells and platelets)
it filters the blood and removes any old or damaged red blood cells
The spleen is not working properly
If the spleen does not work properly, it may start to remove healthy blood cells.
This can lead to:
anaemia, from a reduced number of red blood cells
an increased risk of infection, from a reduced number of white blood cells
bleeding or bruising, caused by a reduced number of platelets
A painful spleen
Spleen pain is usually felt as a pain behind your left ribs. It may be tender when you touch the area.
This can be a sign of a damaged, ruptured or enlarged spleen.
A damaged or ruptured spleen
The spleen can become damaged or may burst (rupture) after an injury, such as a blow to the abdomen, a car accident, a sporting accident or broken ribs.
Rupture can happen straight away or it may happen weeks after the injury.
Signs of a ruptured spleen are:
pain behind your left ribs and tenderness when you touch this area
dizziness and a rapid heart rate (a sign of low blood pressure caused by blood loss)
A ruptured spleen is a medical emergency, as it can cause life-threatening bleeding.
Go straight to A&E if you think you have ruptured or damaged your spleen.
An enlarged spleen
The spleen can become swollen after an infection or injury. It can also become enlarged as a result of a health condition, such as cirrhosis, leukaemia or rheumatoid arthritis.
An enlarged spleen does not always cause symptoms.
Otherwise, look out for:
feeling full very quickly after eating (an enlarged spleen can press on the stomach)
feeling discomfort or pain behind your left ribs
anaemia and fatigue frequent infections easy bleeding
Doctors can often tell if you have an enlarged spleen by feeling your abdomen. A blood test, CT scan or MRI scan can confirm the diagnosis.
The spleen is not usually removed if it's just enlarged. Instead, you'll receive treatment for any underlying condition and your spleen will be monitored. You may be prescribed antibiotics if there's an infection.
You'll need to avoid contact sports for a while, as you'll be at greater risk of rupturing the spleen while it's enlarged.
Surgery to remove the spleen
You may need an operation to remove your spleen, known as a splenectomy, if it's not working properly or it's damaged, diseased or enlarged.
Sometimes just part of your spleen can be removed, which is called a partial splenectomy.
If there's time, you'll be advised to have certain vaccinations before the operation. This is because spleen removal weakens your immune system and can make you more likely to get an infection.
Most operations to remove spleens are carried out using keyhole surgery (laparoscopy).
Keyhole spleen removal allows a surgeon to get inside your tummy (abdomen) to your spleen without having to make large cuts.
This means you'll have less scarring and may recover from the operation more quickly. But you'll still need a general anaesthetic.
The procedure involves:
making several small cuts in your tummy
guiding a laparoscope into your body through one of the cuts so doctors can see what they're doing
passing thin instruments into your tummy through the other cuts to remove your spleen (gas will be pumped into your tummy to make this easier)
The cuts are then stitched up or sometimes glued together.
You may be able to go home the same day, or you may need to stay in hospital overnight.
If you go home the same day, someone will need to stay with you for the first 24 hours.
Open surgery is where one large cut is made. It may be needed if your spleen cannot be removed using keyhole surgery. Often, in emergencies, this is the preferred method.
You'll need a general anaesthetic and may need to stay in hospital for a few days to recover.
Recovering from spleen surgery
It's normal to feel sore and be bruised after a splenectomy, but you'll be given pain relief.
You should be able to eat and drink as normal soon after the operation.
Like any operation, spleen removal carries a small risk of complications, including bleeding and infection.
Your doctor will talk through these risks with you.
You should be given breathing and leg exercises to do at home to reduce your risk of getting a blood clot or a chest infection. In some cases you may also be given blood thinning injections for around 1 to 2 weeks after your surgery.
Another risk is the surgical wound becoming infected. If you spot any signs of infection such as a high temperature or redness and swelling around the wound, contact your GP or hospital immediately. You may need antibiotics.
