Intussusception In Adults

Intussusception, though commonly associated with children, can also affect adults. This condition occurs when one segment of the intestine telescopes into another, causing potentially serious complications.

In this article, we will outline the intricacies of intussusception in adults, shedding light on its causes, symptoms, diagnosis, and the crucial role of imaging techniques in its detection. We’ll also discuss a specific variant known as transient intussusception.

Causes and Risk Factors

Intussusception in adults can stem from various underlying conditions. These may include benign or malignant tumors, scar tissue from previous surgeries, inflammatory bowel diseases, or even certain infections. Additionally, individuals with a history of abdominal surgery or those suffering from conditions like Crohn’s disease or celiac disease may be at higher risk. Transient intussusception, on the other hand, is a unique subtype often associated with a self-limiting, temporary condition that may not have a clear underlying cause.

Common Symptoms

The symptoms of adult intussusception can be nonspecific, often mimicking other gastrointestinal issues. These may encompass abdominal pain, nausea, vomiting, and changes in bowel habits. As these symptoms can overlap with many digestive disorders, early diagnosis becomes crucial. Transient intussusception may present with similar symptoms, but it typically resolves on its own without the need for surgical intervention.

Diagnostic Techniques

  1. Ultrasound Imaging: One of the primary imaging methods for diagnosing intussusception is ultrasound. This non-invasive technique utilizes high-frequency sound waves to create images of the abdominal area. In cases of intussusception, an ultrasound may reveal a characteristic “target” or “doughnut” sign, indicative of telescoping intestines. This sign may not always be present in transient intussusception cases.
  2. Computed Tomography (CT) Scan: CT scans provide detailed cross-sectional images of the abdomen. This imaging technique is highly effective in detecting intussusception and can reveal the site and extent of the telescoping. It also aids in identifying potential causes like tumors or obstructions. Transient intussusception may not always require a CT scan, as it often resolves before the condition becomes evident on this imaging modality.
  3. Magnetic Resonance Imaging (MRI): In certain cases, MRI may be employed to visualize intussusception. It offers excellent soft tissue contrast and can help distinguish between different structures in the abdomen, aiding in a more precise diagnosis. This is particularly useful when evaluating transient intussusception to rule out other underlying causes.

Treatment Options

Once intussusception is confirmed through imaging, prompt intervention is necessary. Surgery may be required to correct the telescoping of the intestine in cases of traditional adult intussusception. However, transient intussusception often resolves without the need for surgical treatment. Close monitoring and follow-up imaging may be recommended to ensure the condition self-resolves.


Intussusception in adults is a rare but potentially serious gastrointestinal condition. Early detection is key to successful treatment, and imaging techniques play a pivotal role in achieving this. Ultrasound, CT scans, and MRI are invaluable tools in diagnosing adult intussusception, allowing healthcare professionals to tailor their approach for optimal patient outcomes.

Transient intussusception, although sharing some common symptoms, is often a self-limiting condition that may not require surgical intervention, highlighting the importance of precise diagnosis through imaging. If you suspect you or someone you know may be experiencing symptoms of intussusception, seek prompt medical attention. Remember, early intervention can make a significant difference in the outcome of this condition.
