Stomach stent

You might have a stent if your cancer is blocking part of your stomach. A stent is a small metal or plastic tube put into the stomach to relieve a blockage and open up the passage. 

Cancer in the stomach can partly or completely block it and make it difficult to swallow.

You have the stent fitted in hospital in the endoscopy department or x-ray department. It usually takes about 30 minutes.

Before your treatment

Your doctor or specialist nurse explains what happens and how they fit the stent. They ask you to sign a form saying that you agree to have the procedure. You can ask them any questions that you have. Tell them about any medicines you are taking.

You shouldn’t eat or drink for at least 6 hours beforehand.

A nurse puts a small tube called a cannula into a vein in the back of your hand. They go with you to the endoscopy or x-ray department.

You have a medicine to make you sleepy injected into the cannula in your hand. Or you might have a general anaesthetic, so that you'll be asleep for the procedure. 

Having a stent

Your doctor passes an endoscope down your food pipe into your stomach. You then have an x-ray so that your doctor can see where the blockage is on a screen. And a stent is then passed through the endoscope to where the narrowing is. They pass the stent down the wire until it's in the right place.

After treatment

You stay in the endoscopy department or x-ray department until the sedation or anaesthetic wears off. You wear an oxygen mask for a short time. A nurse then takes you back to your ward. You need to stay in hospital overnight or for a few days.

The stent expands over a couple of days. This opens up the food pipe or stomach so that food and drink can pass through again.

Eating and drinking with a stent

You can’t eat or drink for the first 2 to 4 hours after having the stent. Your nurse tells you when you can start drinking. Then you can build up to eating soft foods.

You need to have a soft diet because solid food won’t pass through the stent. Your dietitian tells you which foods you can eat.

Tips

  • Take your time when eating and sit upright.
  • Chew food well and remove any lumps or gristle.
  • If you have dentures, wear them to make chewing easier.
  • Sip nourishing fluids while eating to help food pass down through the stent.
  • Avoid tough lumps of meat, white bread and stringy fruits and vegetables.

Side effects

Let your nurse or doctor know if you feel sick. They can give you medicines to reduce sickness.

Tell your nurse or doctor if you have heartburn or acid reflux. They can give you anti acid medicine.

Sleeping upright in bed helps to prevent heartburn. You can use pillows or cushions to support yourself.

You might have some slight bleeding in the stomach. It might give you a metallic taste in your mouth. This usually gets better over a few days.

Your nurse will give you mouthwashes. Tell your nurse if you cough up blood.
 

Damage to the food pipe or stomach can tear it or make a hole (perforation). This is very rare. You might need to have surgery to mend the hole if this happens.

In the first 3 days after having treatment, tell your doctor or nurse straight away if you:

  • have difficulty breathing
  • get severe chest pain
  • vomit blood
  • can’t keep food or drinks down

Your swallowing might change or eating and drinking gets difficult or uncomfortable. Or you may find that you suddenly can’t swallow.This is rare. 

If this happens:

  • try not to panic
  • drink plenty of fizzy or warm drinks to try and clear the blockage
  • walk around as this sometimes helps

Call your doctor or nurse for advice if you still can't swallow.

After a time, the stent might move and food may not be able to pass through. If this happens you won’t be able to swallow and food or drink will come back up. Your doctor will remove or replace the stent.

At home with a stent

You have support from community nurses or your local symptom control team. You also have regular appointments at the hospital to check the stent.

The hospital or your GP give you any medicines that you need.

Other treatments

Your doctor may also offer you chemotherapy to help shrink the cancer and relieve symptoms.

You might also have a drug called trastuzumab (Herceptin) with chemotherapy. You only have this if your cancer has a large amount of a protein called HER2. This is a type of biological therapy that targets cancer cells.
