Summary
Definition
Acute cholecystitis is acute inflammation of the gallbladder, and is one of the major complications of cholelithiasis (the presence of gallstones). In most cases (90%), acute cholecystitis is caused by obstruction of the cystic duct due to a stone in the gallbladder neck or cystic duct, which leads to inflammation within the gallbladder wall.[1] In 5% of cases, bile inspissation (due to dehydration) or bile stasis (due to trauma or severe systemic illness) can block the cystic duct, causing acalculous cholecystitis.[1] [Figure caption and citation for the preceding image starts]: The biliary treeCreated by BMJ Publishing Group [Citation ends].
Bacterial infection can develop as a secondary feature; it is not an initiating event. Infection may be community- or healthcare-acquired. This topic covers community-acquired infection only.
