What is Biliary Atresia?
Biliary Atresia is a liver condition in which the bile ducts become blocked or scarred, preventing bile from leaving the liver and reaching the intestine. This blockage leads to liver damage, as the bile that helps digest fats and absorb vitamins isn’t reaching the gut. It causes jaundice, pale stools, and affects growth and nutrition.

What causes Biliary Atresia and how common is it in New Zealand?
The exact cause of Biliary Atresia is not fully understood but is believed to involve a mix of genetic and environmental factors. It might be linked to a response to viral infections or other issues during pregnancy. In New Zealand, approximately 12 infants are diagnosed with Biliary Atresia each year. It's more common among Pacific Islander and Maori infants compared to Europeans and more prevalent in some Asian countries.

Main course of treatment:
When Biliary Atresia is diagnosed, the primary treatment is the Kasai procedure (portoenterostomy). This surgery involves connecting a part of the bowel to the liver to allow bile to drain. This operation aims to bypass the blocked bile ducts and reduce liver damage. Early diagnosis and prompt surgery are crucial for the best outcomes.
