Why do I need a water-soluble swallow?
Your doctor has decided that you need an examination of your oesophagus - (gullet) and stomach to investigate your symptoms. This test may be performed as part of a series of other tests. However, if you do not want this procedure, please discuss with your doctor and let us know if you decide not to have it done.
What is a water-soluble swallow?
This is a special x-ray procedure to examine the oesophagus and see how you swallow.
Who will be doing the water-soluble swallow?
A specialist x-ray doctor called a Radiologist, or a specially trained radiographer will perform this examination. They are specialists in using x-ray equipment and in understanding the images produced.
How do I prepare for a water-soluble swallow?
It is extremely important to be properly prepared for your examination. For the test to work your oesophagus and stomach must be completely empty. If you are not properly prepared it may result in your test being rebooked.
DO NOT EAT OR DRINK ANYTHING FOR SIX HOURS BEFORE YOUR EXAMINATION.
You may still take any essential medication with a small amount of water.
What happens during a water-soluble swallow?
You may need to undress and put on a hospital examination gown.
During the examination you will be asked to drink some contrast (x-ray dye) liquid whilst being observed on an x-ray screen. You could be lying down or standing - or both - during this examination. You will be asked to move into various positions and the x-ray table may be tilted whilst the x-rays are taken. We may also ask you to swallow some bread.
If you are on a gluten free diet or have dietary requirements, then please bring a slice of bread/biscuit with you or tell the department on your arrival.
How long will it take?
The examination usually takes around 20 minutes, but sometimes will take longer. Rarely follow up x-rays will be needed up to an hour later. The doctor/radiographer will let you know if further x-rays are needed.
What happens next?
The results of your examination will be sent to the doctor who referred you for the examination.
Is x-ray guidance dangerous?
All x-ray machines use potentially harmful x-rays. Modern equipment is designed to keep the dose you receive as low as possible. If your doctor has asked for this test, they will have decided that the benefits from the procedure outweigh the risks from the very small dose of radiation that you receive.
What if I decide not to have the test done?
You will be able to discuss any concerns you have with the radiologist or radiographer. If you then decide not to go ahead with the examination, we will write to your referring doctor to let them know.
Are there any alternatives to this procedure?
Another procedure can be done which allows your oesophagus and stomach to be investigated. This is a camera test – Endoscopy. This investigation may not be suitable for you, so you should discuss it with your consultant. The advantage of this test is that we can watch how the muscles of your gullet work.
What if I’m pregnant?
As x-rays can harm unborn babies, if there is any chance you could be pregnant, please call 0161 206 4941 if your appointment is at Salford Royal Hospital or 0161 656 1178 if your appointment is at Royal Oldham Hospital.
