What is Chilaiditi Syndrome?
Chilaiditi Syndrome is named after the Greek radiologist, Demetrius Chilaiditi, who first described the phenomenon in 1910. It is defined by the abnormal positioning of a portion of the intestine, usually the transverse colon, between the liver and the diaphragm. This displacement can be seen on radiological images and is often incidentally found when patients undergo imaging for unrelated issues.
While the presence of this anatomical anomaly is called Chilaiditi's sign, it becomes Chilaiditi Syndrome when accompanied by clinical symptoms such as abdominal pain, nausea, vomiting, or respiratory difficulties. It is crucial to distinguish between these terms to avoid confusion in diagnosis and treatment.
Causes of Chilaiditi Syndrome
The etiology of Chilaiditi Syndrome can be multifactorial. Here are some factors that contribute to its development:
Anatomical and Physiological Factors
Several anatomical conditions predispose individuals to Chilaiditi Syndrome. These include:
- Liver Atrophy: A smaller liver size, whether congenital or due to cirrhosis, can create space for the colon to shift upwards.
- Diaphragmatic Elevation: Conditions such as obesity or chronic respiratory disorders that elevate the diaphragm may encourage the interposition of the colon.
- Laxity of Ligaments: The weakening of peritoneal ligaments that normally hold the liver and intestines in place can result in abnormal organ positioning.
Lifestyle and Other Factors
- Chronic Constipation: Long-term constipation can lead to increased abdominal pressure, encouraging the displacement of the colon.
- Surgery or Trauma: Prior abdominal surgery or trauma can alter the anatomical landscape, paving the way for Chilaiditi's sign.
- Genetic Predisposition: While not extensively studied, genetic factors may play a role in predisposing certain individuals to this syndrome.

Get A Second OpinionSymptoms of Chilaiditi Syndrome
Chilaiditi Syndrome can present with a range of symptoms, which vary in severity and may overlap with other gastrointestinal or respiratory conditions. Common symptoms include:
- Abdominal Pain: Often localized to the upper right quadrant, the pain can be intermittent or persistent.
- Nausea and Vomiting: These symptoms can result from bowel obstruction or irritation.
- Respiratory Distress: The upward displacement of the colon can impinge on the diaphragm, leading to breathing difficulties.
- Altered Bowel Habits: Some patients experience changes in bowel movements, including constipation or diarrhea.
Diagnosing Chilaiditi Syndrome
Diagnosis of Chilaiditi Syndrome involves a combination of clinical evaluation and imaging studies. It is essential to differentiate it from other conditions such as pneumoperitoneum (air in the abdominal cavity), which requires immediate surgical intervention.
Imaging Techniques
- X-ray and CT Scans: These imaging modalities are instrumental in identifying the interposition of the colon and distinguishing it from free air under the diaphragm.
- Ultrasound: While not the primary diagnostic tool, ultrasound can aid in assessing liver size and diaphragm elevation.
Clinical Examination
A thorough clinical examination is crucial to correlate radiological findings with symptoms. Understanding the patient's medical history and conducting a physical examination can help in ruling out other differential diagnoses.

Book an AppointmentTreatment and Management of Chilaiditi Syndrome
The treatment of Chilaiditi Syndrome is highly individualized and depends on the severity of symptoms and the presence of complications.
Conservative Management
In many cases, conservative management is sufficient. This approach includes:
- Bowel Rest: A temporary cessation of oral intake to reduce bowel activity.
- Nasogastric Decompression: Inserting a tube through the nose into the stomach to relieve pressure and gas.
- Laxatives and Stool Softeners: Addressing constipation to prevent further displacement.
- Pain Management: Using analgesics to alleviate discomfort.
Surgical Intervention
Surgery is reserved for cases where conservative measures fail or complications arise, such as bowel obstruction or ischemia. Surgical options include:
- Colon Resection: Removal of the affected bowel segment.
- Colopexy: Securing the colon to prevent further displacement.
- Laparoscopic Techniques: Minimally invasive surgery to reposition the colon.
Prognosis and Long-term Management
The prognosis for Chilaiditi Syndrome is generally favourable, especially with early detection and appropriate management. Long-term outcomes depend on addressing underlying causes and making lifestyle modifications to prevent recurrence.
Follow-up and Monitoring
Patients should be monitored regularly to assess for symptom recurrence or complications. Regular follow-ups with imaging studies can help in evaluating the effectiveness of treatment and ensuring that the colon remains in its correct anatomical position.
Frequently Asked Questions
1. What are the symptoms of Chilaiditi syndrome?
Symptoms may include abdominal pain, nausea, and vomiting due to intestinal displacement under the diaphragm.
2. What causes Chilaiditi syndrome?
Causes are typically linked to anatomical variations or transient conditions that allow for the colon to move into the space between the liver and diaphragm.
3. How is Chilaiditi syndrome diagnosed?
Diagnosis typically involves imaging studies such as X-rays or CT scans to assess the position of the colon.
4. What treatment options are available for Chilaiditi syndrome?
Treatment may include dietary management and, in severe cases, surgical intervention to reposition the intestine.
5. How does Chilaiditi syndrome relate to intestinal displacement?
It specifically involves the abnormal positioning of the colon, leading to gastrointestinal symptoms.
