What is the term for the condition where 15% of gallstones pass through the cystic duct and enter the common bile duct?

1. Cholecystitis

2. Choledocholithiasis

3. Cholelithiasis

4. Cholangitis

The correct answer is: Choledocholithiasis

The condition in which 15% of gallstones pass through the cystic duct into the common bile duct is known as choledocholithiasis. This term specifically refers to the presence of gallstones within the common bile duct, which can lead to various complications, including obstructive jaundice, pancreatitis, and cholangitis if the stones block the flow of bile. Understanding this condition is crucial in the management of patients presenting with biliary colic, as they may require further evaluation and possible intervention to remove the stones from the bile duct to prevent complications. Other terms referenced in the options provide context about related but distinct conditions; for instance, cholelithiasis refers to the presence of gallstones in the gallbladder itself, cholecystitis refers to inflammation of the gallbladder, and cholangitis is an infection of the bile duct system, which may occur secondary to choledocholithiasis. Hence, choledocholithiasis accurately captures the specific situation where gallstones migrate from the gallbladder into the bile duct.
