You are asked to assess a 7-week-old infant with a history of jaundice and acholic stools. Serum total and direct bilirubin and gamma-glutamyl transferase (GGT) are elevated. Serum α-1-antitrypsin and thyroid testing are normal. Abdominal ultrasound identifies a small, contracted gallbladder. What is the next best step in the management of this infant?
A Hepatobiliary iminodiacetic acid (HIDA) scan
B Percutaneous liver biopsy
C Endoscopic Retrograde Cholangiopancreatography (ERCP)
D Magnetic Resonance Cholangiopancreatography (MRCP)
E Intra-operative cholangiogram and possible Kasai procedure
