Intussusception is a serious type of bowel obstruction. The intestine is shaped like a long tube. Intussusception occurs when one part of the intestine slides up into another part of the intestine. This part of the intestine becomes trapped and starts to swell. The swelling can block the flow of food. If severe, swelling can also cut off the blood supply to the area.

Factors that increase the risk of intussusception include: Age: it is the most common cause of obstruction in children 3 months to 6 years old, but the majority are younger than 24 monthSeason: more common during respiratory and gastrointestinal virus seasons.Sex: maleMedical conditions in the list above
The initial symptoms may include:
Usually severeColicky or crampingUsually comes on suddenlyIn children, this may be indicated by drawing knees to chest and crying.Vomiting—sometimes yellow or green tingedStools mixed with mucus and blood—often described as currant jellyLethargy
Additional symptoms include: Poor feedingDiarrheaShockDehydrationFever
Intussusception cuts off the blood supply to the bowel. If this is not treated quickly, it can lead to bowel gangrene. Gangrene can cause tissue in the intestinal wall to die. This may lead to: Perforation of the intestinal wallPeritonitis
—inflammation of the lining of the abdominal cavity and infection
If not treated quickly, peritonitis can lead to death.
The doctor will ask about your symptoms and medical history. A physical exam will be done.
Bodily fluids may be tested. This can be done with: Blood testsUrine tests
Images may be taken of your bodily structures. This can be done with: Abdominal x-rayUltrasoundCT scan
In many cases, giving an air enema will correct intussusception. Air enema is preferred over water-soluble contrast or barium enema. This is often the preferred treatment when intussusception occurs in infancy. However, the test may cause a perforation to occur in the bowel. An enema should not be done if the bowel is perforated.
Surgery may be required to release the trapped portion of the bowel and to clear the obstruction. If any bowel tissue has died due to gangrene, that part of the bowel may need to be removed.
If you are diagnosed with intussusception, follow your doctor's
There are no guidelines for preventing intussusception because the cause is unknown. Talk to your doctor about avoiding vaccines that may cause a recurrence.
