Intussusception

Overview

Intussusception is a serious problem that happens when part of your intestines slides into another part, like a telescope collapsing. This squeezing action can stop food and liquids from moving through your digestive system. It can also cut off the blood supply to the affected part of the intestines. Without blood flow, the tissue can become infected, die, or even tear. This tear, called a perforation, is a very serious complication.

Symptoms

Babies with Intussusception

Intussusception is a serious condition that can affect babies. It happens when one part of a baby's intestines slides into another part, like a telescope. This can cause a lot of pain.

One of the first signs of this problem in a healthy baby is often sudden, loud crying, usually because of tummy pain. When they cry, they might pull their knees up to their chest. This pain comes and goes, typically every 15 to 20 minutes at first, but the episodes become more frequent and longer as time passes.

Other common signs include:

  • Bloody or mucous-filled stool: This can look like jelly, sometimes described as "currant jelly stool."
  • Vomiting: Throwing up is another possible symptom.
  • A swollen or hard area in the tummy: Sometimes a lump can be felt.
  • Weakness or fatigue: The baby might seem tired or not as active as usual.
  • Diarrhea: Loose, watery stools can also occur.

It's important to understand that not every baby will show all of these symptoms. Some babies might not cry or show any obvious pain. Others might not have blood in their stool or a noticeable lump. And in older children, the pain might be the only sign, without other symptoms.

If you are concerned about your baby's health, it's crucial to seek medical attention immediately. Early diagnosis and treatment are vital for a positive outcome.

When to see a doctor

Intussusception is a serious medical condition that needs immediate attention. If you or your child are experiencing symptoms like those described, get medical help right away.

Babies often show signs of belly pain by pulling their knees to their chest and crying. These are important warning signs that should not be ignored.

Causes

Your intestines are like long tubes. Intussusception happens when one part of your intestine, usually the small intestine, slides into the part next to it. Think of it like pushing one section of a collapsible tube inside another—hence the name "telescoping."

Sometimes, in adults, this sliding is caused by something growing inside the intestine, like a small growth called a polyp or a tumor. This growth, called a "lead point," triggers the normal, wave-like movements of the intestine. These movements then pull the lead point, and the surrounding intestinal lining, into the part of the intestine in front of it. However, many times, doctors can't find a reason why this happens.

Risk factors

Intussusception is a serious condition where part of the intestines slides into another part, like a telescope. It's a common cause of bowel blockages in young children. Several factors increase the chances of developing this problem:

  • Age: Babies and toddlers are much more likely to experience intussusception than older children or adults. It's most frequently seen in children between six months and three years of age. This is because their intestines are still developing.

  • Gender: Boys are slightly more prone to intussusception than girls.

  • Birth Defects: If a baby's intestines don't develop or move into their proper positions during pregnancy (called malrotation), this can increase the risk of intussusception. Normally, the intestines have a specific arrangement, and if this is disrupted, it can create conditions that lead to the telescoping problem.

  • Health Conditions: Some medical conditions can make intussusception more likely. These include:

    • Cystic fibrosis: This is a genetic disorder that affects the lungs and other organs. It can sometimes affect the intestines in ways that increase the risk of intussusception.
    • Henoch-Schönlein purpura (HSP): This is a condition that causes inflammation in blood vessels. Sometimes, it can affect the intestines, leading to a higher risk.
    • Crohn's disease: This is a type of inflammatory bowel disease. It can cause inflammation and damage to the intestines, increasing the chance of intussusception.
    • Celiac disease: This is a condition where the body has an adverse reaction to gluten, a protein found in wheat, barley, and rye. It can cause inflammation in the intestines, potentially increasing the risk of intussusception.

These factors don't guarantee that someone will get intussusception, but they do increase the chance. If you have concerns about your child or yourself, it's essential to talk to a doctor.

Complications

Intussusception is a serious condition where part of the intestine folds into another part, like a telescope. This can block the flow of blood to that section of the intestine. Without prompt treatment, the lack of blood can damage the intestinal wall tissue. This damage can create a hole (perforation) in the intestine. A hole in the intestine can lead to an infection of the lining of the abdomen called peritonitis.

Peritonitis is a very dangerous illness that needs immediate medical care. It often causes:

  • Stomach pain: This pain can be severe and may come and go.
  • Swollen belly: The abdomen might feel hard or distended.
  • Fever: A high temperature is a common sign.
  • Upset stomach: Vomiting is a typical symptom.

Peritonitis can also make a child go into a state of shock. Shock is a life-threatening condition. Symptoms of shock include:

  • Cool, damp skin: The skin might look pale or gray.
  • Fast, weak pulse: The heartbeat might be rapid and less strong than usual.
  • Breathing problems: Breathing could be shallow, rapid, or both.
  • Changes in behavior: The child might be anxious, restless, or very sleepy and unresponsive.

A child in shock may be awake or appear unconscious. If you think your child is going into shock, get emergency medical help right away. Don't delay. Every minute counts.

Diagnosis

Your doctor or your child's doctor will first ask about your symptoms. They might be able to feel a noticeable, sausage-shaped lump in your belly. To be sure what's going on, your doctor might order some tests:

  • Ultrasound or other belly pictures: A test called an ultrasound, an X-ray, or a CT scan (a type of detailed X-ray) can show if there's a blockage in the intestines. This blockage can happen when one part of the intestine slides into another, like a telescope. The pictures might show a pattern that looks like a "bull's-eye," which is a sign of this problem. The pictures can also show if the intestine is damaged or has a hole in it (perforation).
Treatment

Intussusception, where one part of the intestine slides into another, is a medical emergency. Prompt medical attention is crucial to prevent severe dehydration, shock, and infection. If a section of the intestine loses its blood supply, it can die.

Treatment usually begins with a special kind of enema. This enema uses either a liquid or air to push the intestines back into their proper positions. It's both a way to diagnose the problem and to treat it. In around 90% of children, this enema works to fix the intussusception, and no further treatment is needed. However, if the intestine is damaged (perforated), this procedure isn't an option.

It's important to note that intussusception can sometimes come back (recur) in up to 20% of cases. If this happens, the treatment will need to be repeated. Even if you're planning to try an enema, it's essential to talk to a surgeon. There's a small chance the enema could cause a tear or rupture in the bowel.

Sometimes, intussusception resolves on its own without any treatment.

Treatment Options:

  • Enema: A water-soluble liquid or air enema is used to push the intestines back into place. If successful, it's usually a complete cure, especially in children. However, it can't be used if the intestine is damaged. It's important to consult a surgeon, even if this is the planned treatment, because of the small risk of causing further damage.

  • Surgery: Surgery is needed in situations where:

    • The intestine is damaged.
    • The enema doesn't work.
    • A specific object (called a "lead point") is causing the intussusception. Surgery involves carefully repositioning the trapped intestine, removing any blockages, and potentially removing any dead tissue. Surgery is often the first choice for adults and people with severe cases.
