Pediatric liver transplant

Pediatric Liver Transplant MCQ – Most Common Indication

📘 Theme: Hepatobiliary Surgery / Liver Transplantation (DNB SS / NEET SS High Yield)

Clinical Liver Transplant MCQ

Which of the following is the most common indication for pediatric liver transplantation?

A. Biliary atresia
B. Metabolic diseases
C. Alagille syndrome
D. HCV

Answer: A. Biliary atresia

Explanation

Biliary atresia is the most common indication for liver transplantation in children. It presents with persistent jaundice after birth due to progressive obliteration of the extrahepatic biliary tree. The exact etiology remains unclear.

Typical findings include absent or fibrotic extrahepatic bile ducts and a small or absent gallbladder. Liver biopsy is diagnostic and demonstrates bile duct proliferation, portal fibrosis, and cholestasis.

Why other options are incorrect

  • Metabolic diseases: Important indications for pediatric liver transplantation but less common than biliary atresia.
  • Alagille syndrome: A rare genetic disorder causing chronic cholestasis and may require transplantation in selected patients.
  • HCV: An uncommon indication for pediatric liver transplantation.

High-yield teaching points

  • Biliary atresia is the commonest indication for pediatric liver transplantation.
  • Usually presents with persistent neonatal jaundice, pale stools, and dark urine.
  • Kasai portoenterostomy is the initial surgical treatment.
  • Many patients eventually progress to cirrhosis and require liver transplantation.
  • Early diagnosis improves outcomes.
