What condition is characterized by the abnormal presence of gallstones?

• A. Cholecystitis
• B. Cholelithiasis
• C. Malabsorption syndrome
• D. Pancreatitis

Answer: (B)

Cholelithiasis is the condition that specifically refers to the formation of gallstones within the gallbladder. Gallstones are solid particles made of cholesterol or bilirubin that can form when there is an imbalance in the substances that make up bile. This condition can lead to blockages in the biliary tract, potentially causing pain and other complications.

Cholecystitis, which involves inflammation of the gallbladder, can result from cholelithiasis if a gallstone obstructs the cystic duct, causing irritation and infection. However, cholecystitis itself is not defined by the presence of gallstones, but rather by inflammation. Malabsorption syndrome, on the other hand, relates to the absorption processes in the intestines rather than gallstones. Lastly, pancreatitis involves inflammation of the pancreas, which can sometimes be a secondary complication of gallstones, but it is not characterized by their presence. Therefore, cholelithiasis directly addresses the issue of abnormal gallstone formation.
