Answer

Ultrasonography of liver and bile ducts is used to identify anatomic causes of obstructive cholestasis (eg, choledochal cyst, gallstones).

Abdominal CT scanning is used to identify anatomic causes of obstructive cholestasis (eg, choledochal cyst, gallstones).

Biliary nuclear medicine study (ie, hepatoiminodiacetic acid [HIDA] scanning) is used to identify anatomic causes of obstructive cholestasis (eg, choledochal cyst, gallstones) and to differentiate between obstructive and hepatocellular cholestasis (ie, biliary atresia versus neonatal hepatitis).

Endoscopic retrograde cholangiography is used to identify anatomic causes of obstructive cholestasis (eg, choledochal cyst, gallstones).

Percutaneous transhepatic cholangiography is used to identify anatomic causes of obstructive cholestasis (eg, choledochal cyst, gallstones).
