What is the term for the condition where a gallstone obstructs the common bile duct?

The correct term for the condition where a gallstone obstructs the common bile duct is choledocholithiasis. This condition specifically refers to the presence of one or more gallstones in the common bile duct, which can lead to obstruction and potentially result in serious complications if not addressed.

In choledocholithiasis, the obstruction can cause bile to back up in the liver and gallbladder, leading to jaundice, pain, and even infection. Treating this condition often requires medical intervention to remove the stone and relieve the obstruction.

Cholecystitis refers to inflammation of the gallbladder, often due to gallstones but it does not specifically indicate that the stone is located in the common bile duct. Cholangitis is an infection of the bile duct system, which can occur as a complication of choledocholithiasis but does not specifically describe the obstruction. Hepatitis is inflammation of the liver and is unrelated to gallstones or the bile duct.
