Before your operation for stomach cancer

Before surgery, you have tests to check your fitness and meet members of your treatment team. You usually go into hospital on the morning of your operation or the day before.

The length of your hospital stay depends on what operation you have. You are usually in hospital for at least 9 days after surgery to remove your stomach. 

Tests to check you are fit for surgery

You have tests before your operation to check:

  • your fitness for an anaesthetic, if you need one
  • that you’ll make a good recovery from surgery

You might have some or all of the following tests:

  • blood tests to check your general health and how well your kidneys are working
  • a swab test to rule out some infections
  • an ECG Open a glossary item to check that your heart is healthy
  • breathing tests (called lung function tests)
  • an echocardiogram Open a glossary item 
  • a chest x-ray to check that your lungs are healthy
  • a cardio pulmonary exercise test (which checks your heart and lung function when you're resting and exercising)

Pre assessment clinic

Before your surgery, you have an appointment at the hospital pre assessment clinic. This prepares you for your operation.  

You might meet some members of your treatment team at this appointment. They will ask you questions about your general health. It is important to take a list of any medications you use.

Your doctor and nurses might tell you about the enhanced recovery programme. This is a way of caring before, during and after your surgery to help you recover faster after a big operation.  It includes advising you about:

  • being physically active
  • stopping smoking
  • drinking less alcohol
  • eating well before your surgery

Your healthcare team

A team of doctors and other healthcare professionals will be involved in your treatment.  You will meet them before your surgery.

The surgeon

A member of the surgical team will tell you about:

  • the operation you are going to have
  • the benefits of having surgery
  • the possible risks
  • what to expect afterwards

Your surgeon will also ask you to sign the consent form.

The clinical nurse specialist (CNS)

Your clinical nurse specialist (CNS) is a qualified nurse who has specialist knowledge of cancers of the stomach. They help to organise care between doctors and the other health professionals you need to see. They also support you through your treatment, and make sure you have the information you need to understand your cancer and treatment. Your CNS will support you through any treatment you have.

The dietician

The dietitian gives you help and advice about managing your diet. They:

  • help you get as well as possible before your operation
  • explain how the surgery affects your diet
  • give useful tips on how to increase your nutrients and calories
  • give you advice about eating after your surgery

They might give you nutritional supplement drinks to have before surgery.

The anaesthetist

The anaesthetist gives you the anaesthetic and they look after you during the operation. The anaesthetic is the medicine that keeps you asleep during your operation. They make sure you’re fit enough for the surgery.

The physiotherapist

The physiotherapist teaches you exercises to help you recover from your operation. 

Breathing exercises help to stop you from getting a chest infection after surgery. If you smoke, it helps if you can stop at least a few weeks before your operation.

Leg exercises help to stop blood clots forming in your legs. You might also have medicines to stop the blood from clotting. You have them as small injections under the skin.

You start the injections after your operation. You might also wear compression stockings and pumps on your calves or feet to help the circulation.

Your nurse and physiotherapist will get you up out of bed quite quickly after your surgery. This is to help prevent chest infections and blood clots forming.

This 3-minute video shows you how to do the breathing and leg exercises.

Going into hospital

You might go into hospital the evening before or the morning of your surgery.

Your nurse might give you a carbohydrate-rich drink to have the evening before the operation. You might also have it the following morning. The drink gives you energy and can speed up your recovery.

Your doctor or nurse will tell you when to stop eating and drinking before your operation. 

The length of your hospital stay depends on what operation you have. You are usually in hospital for at least 9 days after surgery to remove your stomach.

  • the best number for friends and family to phone, to find out how you are

The letter you receive before your operation may contain this information. But if not, you can phone the ward or hospital reception to find out.
