Please read the information and follow the instructions carefully.
Why do I need a Water-Soluble Enema?
Your doctor has decided that you need an investigation of your large bowel (colon). This test may be performed as part of a series of other tests.
What is a Water-Soluble Enema?
It is an examination of your large bowel (colon). Contrast (x-ray dye, a colourless liquid) which shows up on x-rays is used to fill your bowel so that we can see it clearly.
Who has made this decision?
Your doctor thinks you need this examination to look at your bowel. However, if you do not want the procedure, discuss it with your doctor and then let us know if you decide not to have it. The contact details are at the end of this leaflet.
Who will be doing the Water-Soluble Enema?
A specialist doctor or a specially trained radiographer will perform your examination. They are trained to use the x-ray equipment and to understand the images produced. They need to look at these images while carrying out the procedure, to make sure that everything your doctor is interested in is included.
How do I prepare for the examination?
Sometimes we may ask you to take bowel preparation and restrict your diet. If this is necessary, a leaflet explaining this will be enclosed with this patient information. If you are unsure or have any queries, please telephone a Radiographer on 0161 206 4941.
What happens during a Water-Soluble Enema?
You will need to undress and put on a hospital gown. You may bring a dressing gown.
During the examination you will be asked to lie on the x-ray table and a small soft plastic tube will be inserted into your back passage and contrast (x-ray dye) will be put through the tube, into your bowel so that your bowel can be seen on the x-rays taken.
You may be asked to move into different positions and the table may be tilted while the x-rays are taken. We will give you clear instructions and help you to do this.
Once the procedure is finished the tube will be removed and you will be shown to a private toilet next to the x-ray room where you can get changed and then go home.
If you have a stoma, please bring some spare stoma bags with you in case you need to change your bag.
Will it hurt?
The examination may be a little uncomfortable and will make you feel like you need to go to the toilet. You may feel full and get cramp-like pains in your tummy. It should not be painful.
How long will it take?
The examination usually takes around 30 minutes.
What happens next?
The results of your examination will be sent to the doctor who referred you.
Are there any risks or complications?
A water-soluble enema is a safe examination but there are some risks and complications that can arise:
There may be a little bleeding from the back passage following the test, but this generally stops without the need for any action.
You may feel mild to moderate cramps in your tummy until all the liquid is out of your bowel.
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 Water-Soluble Enema done?
You will be able to discuss any concerns you have with the radiologist or radiographer. If you 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?
Other procedures can be done to look at your large bowel. These are a camera test (Endoscopy), MRI scan or a CT scan. These investigations may not be suitable for you so you should discuss them with your consultant. The benefit of this examination is that the doctor or radiographer can watch a live, moving image of your bowel on an x-ray screen.
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.
All persons of childbearing age will be asked if they could be pregnant when x-rays are to be used.
If you require alternative tests or treatments due to pregnancy, then your doctor will discuss this at your next appointment.
