Which condition is an example of obstructive liver diseases?

• A. Cholangiocarcinoma
• B. Hepatitis
• C. Cirrhosis
• D. Fatty liver

Answer: (A)

Obstructive liver diseases occur when something blocks the bile ducts, preventing bile from leaving the liver and causing cholestasis. Cholangiocarcinoma is cancer of the bile ducts themselves, which can grow and narrow or block these ducts, directly producing biliary obstruction. That makes it a classic example of an obstructive process in the liver. Hepatitis involves inflammation of liver cells and is primarily hepatocellular, not obstructive. Cirrhosis is scarring that distorts liver architecture and impairs function, but it doesn’t inherently block the bile ducts. Fatty liver is a metabolic buildup of fat in liver cells, also not about duct obstruction.
