Which of the following best describes the nature of Cholecystitis?

Cholecystitis refers to the inflammation of the gallbladder, and it is most commonly associated with the presence of gallstones, which block the cystic duct. When the duct is obstructed, it can lead to an accumulation of bile, resulting in inflammation and infection. This link to gallstones is a foundational aspect of understanding cholecystitis, as many cases are precipitated by gallstone disease.

While some cases of cholecystitis can be acute and lead to significant symptoms, it is not exclusively acute; chronic inflammation can also occur. High fever may be present in acute cholecystitis due to infection, but it is not a defining feature of all cases. Lastly, cholecystitis typically causes significant abdominal pain, particularly in the right upper quadrant, due to the inflammation of the gallbladder. Thus, the most accurate description of cholecystitis is its association with gallstones.
