Cholangitis - Neonatal Disorders

What is Cholangitis?

Cholangitis is an inflammation of the bile ducts, which can lead to severe complications if not promptly treated. It is a relatively rare but serious condition in the pediatric population, often associated with bacterial infection. The most common types are acute cholangitis and primary sclerosing cholangitis.

What Causes Cholangitis in Children?

The most common cause of cholangitis in children is a bacterial infection, often secondary to an obstruction in the bile ducts. This obstruction can be due to biliary atresia, choledochal cysts, or gallstones. Other causes include congenital anomalies and post-surgical complications.

What are the Symptoms?

Symptoms of cholangitis in children can vary but commonly include:
Fever
Jaundice
Abdominal pain, particularly in the right upper quadrant
Dark urine
Pale stools
Nausea and vomiting

How is Cholangitis Diagnosed?

Diagnosis of cholangitis typically involves a combination of clinical evaluation, laboratory tests, and imaging studies. Blood tests may show elevated liver enzymes, bilirubin levels, and white blood cell count. Ultrasonography and Magnetic Resonance Cholangiopancreatography (MRCP) are commonly used imaging techniques to identify bile duct obstructions and inflammation. In some cases, an Endoscopic Retrograde Cholangiopancreatography (ERCP) may be required for both diagnosis and treatment.

What is the Treatment?

Early and aggressive treatment is crucial to managing cholangitis in children. The mainstay of treatment includes:
Intravenous antibiotics to combat bacterial infection
Supportive care, including hydration and pain management
Interventional procedures to relieve bile duct obstruction, such as ERCP or surgical intervention
In severe or recurrent cases, liver transplant may be considered

What are the Complications?

Untreated cholangitis can lead to serious complications, including sepsis, liver abscesses, and chronic liver disease. In severe cases, it can result in liver failure, which may necessitate a liver transplant.

How Can Cholangitis be Prevented?

Preventing cholangitis involves addressing the underlying causes. For children with known biliary anomalies or post-surgical risk, regular monitoring and early intervention are key. Maintaining good hygiene and timely treatment of infections can also help reduce the risk.

Prognosis

The prognosis for children with cholangitis varies depending on the underlying cause and the promptness of treatment. With early and appropriate medical intervention, most children recover well. However, those with chronic conditions like primary sclerosing cholangitis may require ongoing medical care and potentially a liver transplant.
