Intussusception in Infants, Children, and Adults: What You Need to Know

April 3, 2023

What is Intussusception and How Does it Occur?

Intussusception is a medical condition where one part of the intestine slides into the next, similar to how a telescope collapses. This can cause a blockage in the intestine, leading to severe abdominal pain, vomiting, and sometimes even shock. Intussusception is most common in infants and young children, but it can also occur in adults.

Causes of Intussusception

The exact cause of intussusception is not fully understood, but it is thought to be related to a number of factors, including:

  • Viral infections: Some viral infections, such as rotavirus, have been linked to an increased risk of intussusception.

  • Abnormal growths: Polyps or tumors in the intestine can cause intussusception by acting as a “lead point” for the intestine to fold on.

  • Structural abnormalities: Certain congenital abnormalities, such as Meckel’s diverticulum, can also lead to intussusception.

Symptoms of Intussusception

The symptoms of intussusception can vary depending on the severity of the condition and the age of the person affected. In infants and young children, the most common symptoms include:

  • Abdominal pain: Intense abdominal pain is the most common symptom of intussusception. It is often described as a “colicky” pain, meaning it comes and goes in waves.

  • Vomiting: Many infants and children with intussusception will also experience vomiting.

  • Bloody stool: In some cases, the intestine may bleed, leading to the presence of blood in the stool.

  • Lethargy: Infants and children with intussusception may become listless or lethargic as the condition progresses.

In adults, the symptoms can be different as adults have a more developed nervous system and can communicate their pain. Symptoms may include:

  • Abdominal pain: Intense abdominal pain is the most common symptom of intussusception in adults.

  • Vomiting: Many adults with intussusception will also experience vomiting.

  • Diarrhea: In some cases, the intestine may become blocked, leading to diarrhea.

  • Rectal bleeding: In some cases, the intestine may bleed, leading to the presence of blood in the stool.

Diagnosis of Intussusception

The diagnosis of intussusception is typically made based on a combination of the person’s symptoms, a physical examination, and imaging studies.

  • Physical examination: During a physical examination, a doctor may feel a “sausage-shaped” mass in the abdomen, which is a characteristic sign of intussusception.

  • Imaging studies: Imaging studies, such as an ultrasound or a CT scan, can help to confirm the diagnosis of intussusception. These studies can also help to determine the location and severity of the intussusception.

Treatment of Intussusception

Treatment for intussusception typically involves reducing the intussusception in order to relieve the blockage. This is usually done through one of two methods:

  • Air enema: An air enema is a procedure where a tube is inserted into the rectum and air is used to reduce the intussusception.

  • Surgery: In some cases, surgery may be necessary to reduce the intussusception. This may be necessary if the air enema is not successful or if the intussusception is located in a difficult-to-reach area.

The success rate of reducing intussusception via air enema is about 80-90%. In case of failure, surgery is usually the next step. Surgery is also the first line of treatment for adults.

Complications and Prognosis

Intussusception can lead to a number of complications if left untreated, such as:

  • Intestinal obstruction: The intestine can become completely blocked, leading to an inability to pass gas or stool.

  • Perforation: In rare cases, the intestine may become perforated, leading to an infection in the abdomen.

  • Shock: Intussusception can lead to shock if enough blood is not flowing to the vital organs.

With prompt diagnosis and treatment, the prognosis for intussusception is generally good. However, if the condition is not treated in a timely manner, it can lead to serious complications.

Prevention and Management of Intussusception

There is currently no way to prevent intussusception from occurring, but there are steps that can be taken to manage the condition:

  • Vaccination: Vaccination against rotavirus can help to reduce the risk of intussusception in infants and young children.

  • Early diagnosis: Early diagnosis and treatment of intussusception is crucial in order to prevent complications.

  • Follow-up care: After treatment, it’s important to follow-up with a doctor to make sure that the intussusception has been completely resolved and to monitor for any complications.

The symptoms of intussusception can vary depending on the severity of the condition and the age of the child. In infants and young children, the most common symptoms include:

  • Abdominal pain: Intense abdominal pain is the most common symptom of intussusception. It is often described as a “colicky” pain, meaning it comes and goes in waves. The child may cry and draw their legs up to the abdomen.

  • Vomiting: Many infants and children with intussusception will also experience vomiting. The vomit may be bilious (greenish-yellow) if the intussusception is in the small intestine or it can be non-bilious.

  • Bloody stool: In some cases, the intestine may bleed, leading to the presence of blood in the stool, also called “currant jelly” stool.

  • Lethargy: Infants and children with intussusception may become listless or lethargic as the condition progresses.

Other symptoms may include:

  • Fever: The child may have a low-grade fever.
  • Abdominal distention: The abdomen may appear swollen or distended.
  • Dehydration: Due to vomiting, the child may become dehydrated.

It’s important to note that some children may not have any symptoms or have mild symptoms which can make the diagnosis more challenging.

Treatment for Adults

The treatment options for intussusception in adults are the same as for children, but with different success rate. The success rate of reducing intussusception via air enema is lower in adults (about 30-50%). Therefore, surgery is usually the first line of treatment for adults.

Medications

Medications may also be prescribed to help manage the symptoms of intussusception.

  • Pain relievers: Pain relievers such as ibuprofen or acetaminophen may be prescribed to help manage the abdominal pain associated with intussusception.
  • Anti-inflammatory medication: Corticosteroids may be prescribed to reduce inflammation and swelling in the intestine.

Follow-up Care

After treatment, it’s important to follow-up with a doctor to make sure that the intussusception has been completely resolved and to monitor for any complications. In case of surgery, the recovery time may vary depending on the location and severity of the intussusception.

  • Perforation: In rare cases, the intestine may become perforated, leading to an infection in the abdomen (peritonitis). This can be life-threatening if not treated promptly.

  • Shock: Intussusception can lead to shock if enough blood is not flowing to the vital organs. This can be life-threatening if not treated promptly.

  • Recurrence: Intussusception may recur after treatment, especially if the underlying cause is not identified and treated.

Prognosis

The prognosis for intussusception depends on a number of factors, such as the location and severity of the intussusception, the underlying cause, and how quickly the condition is treated. With prompt diagnosis and treatment, the prognosis for intussusception is generally good. However, if the condition is not treated in a timely manner, it can lead to serious complications.

In general, the prognosis for children with intussusception is good. The overall complication rate is less than 5% and the mortality rate is less than 1%. However, the outcome is worse for adults with intussusception. The rate of complications and mortality is higher in adults.

This can cause a blockage in the intestine, leading to severe abdominal pain, vomiting, and sometimes even shock. Intussusception is most common in infants and young children, but it can also occur in adults. Understanding the prevention and management of intussusception in high-risk populations is crucial in order to reduce the incidence and improve the outcome.

High-Risk Populations

Intussusception is most common in infants and young children, with the majority of cases occurring before the age of 2 years. However, certain populations may have an increased risk of developing intussusception, such as:

  • Infants: Infants are at the highest risk of developing intussusception.

  • Children with a history of previous intussusception: Children who have had intussusception in the past are at an increased risk of developing the condition again.

  • Children with certain medical conditions: Children with certain medical conditions, such as cystic fibrosis or Hirschsprung’s disease, are at an increased risk of developing intussusception.

  • Children who have been recently vaccinated: Children who have been recently vaccinated with the rotavirus vaccine may have an increased risk of developing intussusception.

Prevention of Intussusception

There is currently no way to prevent intussusception from occurring, but there are steps that can be taken to reduce the risk of intussusception in high-risk populations:

  • Vaccination: Vaccination against rotavirus can help to reduce the risk of intussusception in infants and young children. This vaccine is recommended for all infants between 2-8 months of age.

  • Early diagnosis: Early diagnosis and treatment of intussusception is crucial in order to prevent complications.

  • Follow-up care: After treatment, it’s important to follow-up with a doctor to make sure that the intussusception has been completely resolved and to monitor for any complications.

Management of Intussusception
