The gold standard for evaluation of patients with bile duct strictures is cholangiography. The two routes for cholangiography are percutaneous transhepatic cholangiography (PTC) or endoscopic retrograde cholangiography (ERC). Which of the following statement(s) is/are true?
A. PTC is generally more valuable than ERC in defining the proximal biliary tree to be used in reconstruction
B. ERC is technically easier in patients with bile leaks because the biliary tree is usually not dilated
C. Parenteral antibiotics should be administered prior to either procedure to prevent cholangitis
D. Biliary stents can be placed via either technique to control biliary leaks
