Question
What is the difference between neonatal biliary atresia and choledochal obstruction?
Answer
Cholestasis during pregnancy is a special condition that occurs only in pregnant women, characterized by skin itching, usually appearing between the 28th to 30th week of pregnancy, but it can occur as early as the 12th week. As pregnancy progresses, the itching sensation intensifies, primarily affecting the trunk and lower limbs, and may impact the entire body severely, especially at night, affecting sleep. Choledochal obstruction is mainly caused by congenital developmental abnormalities, which may be due to choledochal atresia or obstruction. This can be distinguished through color Doppler ultrasound or CT scans.
