Alagille syndrome vs biliary atresia

Alagille syndrome and biliary atresia can cause similar effects and symptoms. In Alagille syndrome, your bile duct can restrict the flow of bile to the small intestine, causing bile to back up into the liver. In biliary atresia, damage or scarring of the bile ducts causes the same symptoms.

What can be mistaken for biliary atresia?

Alagille syndrome and biliary atresia can cause similar effects and symptoms. In Alagille syndrome, your bile duct can restrict the flow of bile to the small intestine, causing bile to back up into the liver. In biliary atresia, damage or scarring of the bile ducts causes the same symptoms.

What is the diagnostic criteria for Alagille syndrome?

A diagnosis of Alagille syndrome is confirmed by a liver biopsy that shows fewer bile ducts than normal and at least 3 of these symptoms: Face shapes characteristic of Alagille syndrome. Unusual bone/spine structures such as a butterfly vertebrae. Unusual heart/blood vessel structures or a heart murmur.

What is the difference between biliary atresia and stricture?

In biliary atresia, the bile ducts outside the liver (extrahepatic bile ducts) are abnormal and are damaged by a progressive inflammatory process. Over time, biliary strictures (narrowing of the bile ducts) form preventing bile from draining into the intestine from the liver.

What is another name for biliary atresia?

Biliary atresia, also known as extrahepatic ductopenia and progressive obliterative cholangiopathy, is a childhood disease of the liver in which one or more bile ducts are abnormally narrow, blocked, or absent. It can be congenital or acquired.

What is a differential diagnosis of Alagille syndrome?

Differential diagnoses include biliary atresia, congenital hepatic fibrosis, cystic fibrosis, neonatal jaundice, polycystic kidney disease, progressive familial intrahepatic cholestasis, and tyrosinemia (see these terms).

Can biliary atresia be misdiagnosed?

Abstract. Background: Biliary atresia (BA) is one of the most common and perplexing causes of neonatal cholestasis. Each year many cases of neonatal cholestasis are misdiagnosed as BA, resulting in unnecessary exploratory surgery.

What is the Alagille syndrome triad?

Alagille syndrome is an autosomal dominant, complex multisystem disorder characterized by the presence of three out of five major clinical criteria: cholestasis with bile duct paucity on liver biopsy, congenital cardiac defects (with particular involvement of the pulmonary arteries), posterior embryotoxon in the eye, ...

What is the Watson Miller syndrome?

Alagille syndrome (ALGS) is a multisystem autosomal dominant disorder with a wide variety of clinical manifestations. It is also known as arteriohepatic dysplasia, Alagille-Watson syndrome, Watson-Miller syndrome, or syndromic bile duct paucity.

What is mild Alagille syndrome?

Symptoms of liver disease in subjects with Alagille syndrome range from mild to severe. Symptoms within the first three months of life often include: Jaundice (yellowing of skin), usually present at birth. Severe itching. Pale, loose or clay-colored stools.

What is the gold standard for biliary atresia diagnosis?

Functional tests which assess bile duct patency can exclude BA in younger infants who have bile duct obstruction but few other symptoms. For example, BA's gold-standard test—the intraoperative cholangiogram (IOC)—directly outlines the biliary tract by surgically isolating the gall bladder and injecting it with dye.
