Intussusception is a serious problem in the intestine. It occurs when one part of the intestine slides inside another part. The intestine then folds into itself like a telescope. This creates a blockage or obstruction. It stops food that is being digested from passing through the intestine.
Intussusception is the most common cause of intestinal blockage in children between ages 3 months and 3 years. It is rare in newborn babies. But it can also occur in older children, teenagers, and adults.
Intussusception is a medical emergency. It's the most common abdominal emergency in early childhood. If not treated, it can cause infection or even death.
Experts don’t know what causes intussusception. It may occur more often in children who have a family history of the disorder.
Experts have found a link in some cases with other conditions. These include viral infection, abdominal or intestinal tumors or masses, appendicitis, parasites, celiac disease, cystic fibrosis, and Crohn's disease.
Intussusception is a medical emergency. If you think your child may have the disorder, see your child's healthcare provider right away.
Each child’s symptoms may vary. The most common symptom is sudden, loud crying. This is caused by sudden, severe belly (abdominal) pain in an otherwise healthy child.
This belly pain occurs often. At first it may seem to be colic. Infants or children may strain, draw their knees up, act very irritable, and cry loudly. Your child may feel better and be playful between bouts of pain. Or your child may become tired and weak from crying.
Other symptoms include:
Symptoms of intussusception may seem like other health problems. See your child's healthcare provider for a diagnosis.
Your child’s healthcare provider will take a health history and give your child a physical exam. Imaging studies are also done to check the belly (abdominal) organs. These tests may include:
Treatment will depend on your child’s symptoms, age, and general health. It will also depend on how severe the condition is.
Sometimes intussusception will repair itself while a child has a barium enema. In many cases, the healthcare provider can correct the problem by giving an air enema or saline enema. This is done by placing a small tube in your child's rectum. The healthcare provider uses ultrasound or X-rays (fluoroscope) to help place the tube. Air is inserted in the tube. The air may help move the intestine back into its normal position. But if your child is very ill with an abdominal infection or other problems, the provider may choose not to do this.
Your child will need surgery if the intussusception is not repaired with a barium enema. Your child will also need surgery they are too ill to have a barium enema, saline enema, or air enema. For the surgery, your child will be given anesthesia. The surgeon will make a cut or incision in the belly. The surgeon will find the intussusception, and push the parts of the intestine back into place. The intestine will be checked for damage. If any sections are not working properly, they will be removed.
If your child’s intestine is damaged and the part removed is small, the two sections of healthy intestine will be sewn back together.
In very rare cases, a large amount of intestine may be removed. This happens if the damaged section of intestine is large. In this case, surgery can’t link together the parts of the intestine that remain after the damaged section is removed. An ileostomy may be done so that the digestive process can continue. With an ileostomy, the two remaining healthy ends of intestine are brought through openings in the belly. Stool will pass through the opening (stoma). It will then collect in a bag on the outside of the body. The ileostomy may be short-term. Or in very rare cases it may be long-lasting or permanent. It depends on how much intestine was removed.
Intussusception is a medical emergency. It is a life-threatening illness. If not treated, it can cause serious problems such as:
If not treated, intussusception is a life-threatening disorder.
Your child’s long-term outlook depends on how much damage was done to the intestines. Children who had the damaged part of their intestine removed may have long-term problems. Removing a large part of the intestine can affect the digestive process. These children may need to eat and drink more to get the nutrients and fluids that they need.
