Cholecystitis is inflammation of the gallbladder, usually resulting from a gallstone blocking the cystic duct.
Typically, people have abdominal pain that lasts more than 6 hours, fever, and nausea.
Ultrasonography can usually detect signs of gallbladder inflammation.
The gallbladder is removed, often using a laparoscope.
Cholecystitis is the most common problem resulting from gallbladder stones. It occurs when a stone blocks the cystic duct, which carries bile from the gallbladder (see Figure: View of the Liver and Gallbladder).
Cholecystitis is classified as acute or chronic.
