Chronic cholecystitis

[Greta]

Chronic cholecystitis is long-standing gallbladder inflammation almost always due to gallstones.
(See also Overview of Biliary Function.)
Chronic cholecystitis almost always results from gallstones and prior episodes of acute cholecystitis (even if mild). Damage ranges from a modest infiltrate of chronic inflammatory cells to a fibrotic, shrunken gallbladder. Extensive calcification due to fibrosis is called porcelain gallbladder.
