Barium enema (irrigography)

A barium enema, or irrigography, is an X-ray of the large bowel with contrast put in through the rectum. The contrast fills the bowel from inside. The images show its shape, length, width and the position of the loops. Irrigoscopy is the same test when the doctor also watches the bowel fill on a screen in real time. At Oberig Clinic, we do it in the X-ray room of the Diagnostic Department. The price list offers it for children under 3.

When children need it

Most often a pediatrician, a pediatric gastroenterologist or a surgeon orders it when a baby has lasting bowel problems. Typical reasons:

• long-term constipation from the first weeks or months that does not improve with diet changes
• a swollen belly, when the baby rarely passes gas or stool without an enema
• suspected Hirschsprung disease, when part of the bowel lacks nerve cells and does not push contents along
• a suspected long or unusually placed large bowel (dolichosigmoid, megacolon)
• a check after bowel surgery

Irrigography shows the anatomy of the bowel, not its lining. That makes it most useful when the shape and size matter more than small signs of inflammation.

In Hirschsprung disease, the images usually show a narrow segment low down and a much wider bowel above it, where contents build up. The doctor describes this transition zone, because it tells the surgeon how much bowel is affected. A biopsy of the rectal wall confirms the diagnosis. With a dolichosigmoid, you see extra loops of a long sigmoid colon. Contents move slower through them. These kids often do well with diet and routine, and the image explains why constipation keeps coming back.

Barium or another contrast

The classic test uses barium sulfate. It shows up well and is not absorbed. Sometimes the doctor picks a water-soluble contrast, for example after surgery or if a blockage is suspected. Your referral may say barium enema or contrast enema. It is the same method with a different agent.

The radiation dose of modern X-ray is low. The doctor keeps the number of images to the minimum needed. Children get their own machine settings. Areas outside the frame are covered with shields. One test is not dangerous, but nobody does it without a reason. The doctor orders it when the answer will change treatment.

How to prepare your child

The bowel should be clean. Leftover stool can look like a defect and blur the result. The doctor who orders the test gives you the exact plan. In some conditions, such as suspected Hirschsprung disease, the bowel is not cleaned at all. Usually your child gets a cleansing enema the evening before and in the morning. For a day before, skip foods that cause gas. Come on an empty stomach or 3-4 hours after the last feed. Bring a diaper, spare clothes and a favorite toy.

Toddlers pick up on how their parents feel, so a calm voice and a familiar blanket do more than any explanation, and a short story about what will happen helps a three-year-old far more than you might expect. Plan the day so your child is not overtired. Arrive 10-15 minutes early. That gives you time to settle in, change a diaper and ask the doctor any questions before the test starts.

How the test goes

Your child lies on the X-ray table. You can stay close in a protective apron. The doctor gently places a thin soft tube in the rectum and slowly fills the bowel with contrast while watching the screen. Then the doctor takes a few images, turning your child onto the side and the tummy. The contrast comes out naturally. The doctor removes part of it right away. The whole test takes 20-30 minutes.

For older kids and adults, the idea is the same. The patient just changes position on the doctor's cue. In a double-contrast study, a little air goes in after the barium. It opens up the walls and shows the surface better.

Normal findings and what can be found

Normally, all parts fill evenly. The outline is smooth, the width is usual, the typical folds (haustra) are visible, and the sigmoid length fits the age. The doctor notes any narrowing, widening above it, extra loops, pouches in the wall (diverticula) or filling defects. The doctor who ordered the test makes the final call, together with the exam and lab results.

What next? If the bowel has a normal shape and size, the cause of constipation is usually diet, routine or pelvic floor muscles. Treatment is mostly without surgery. If the test finds a narrow segment or a big widening, a pediatric surgeon sees your child. Keep the images. At follow-ups, the doctor compares them over time.

Barium enema or colonoscopy

Colonoscopy shows the lining from inside. It lets the doctor take a biopsy and remove a polyp. For adults it is the main test. A barium enema shows the shape, length and position of the bowel and needs no scope. That is why it often comes first for toddlers with constipation. A small child needs anesthesia for colonoscopy, and a barium enema does not. Adults who cannot have colonoscopy have a scope-free option: virtual colonoscopy on CT. Read about the scope test on the colonoscopy page.

Common questions

Does it hurt?

No pain, but the tube and the feeling of fullness are unpleasant. Your child may cry. It is short, and having mom close helps.

Do you do it for adults?

The price list offers it for children under 3. Adults usually get colonoscopy or CT colonography. If your doctor ordered a barium enema, ask the contact center.

What to do after the test?

Give your child more to drink. Stools may look pale for 1-2 days. That is leftover contrast, and it is normal. If there is no stool for more than a day, or the belly is swollen and sore, call the doctor. Barium should not stay in the bowel.

Can I feed my child right after?

Yes. Go back to the usual feeding right away. No limits unless the doctor says otherwise. Many babies are hungry after the test, and a feed is also the fastest way to calm them down.

Is the radiation a concern?

The dose is small and kept as low as possible. The doctor only orders the test when the result will guide treatment.

When will I get the report?

Diagnostic Department results are ready within 24 hours, except weekends and holidays. You get the images and report to show any doctor.
