Acute Cholecystitis
摘要
Acute cholecystitis is an inflammatory state characterized by mucosal inflammation, edema, gallbladder wall distention, and thickening. While this is typically a result of cystic duct obstruction with gallstones, low-perfusion states in critically ill patients or biliary stasis can lead to acalculous cholecystitis. Early diagnosis and treatment are essential, as untreated acute cholecystitis can lead to gallbladder ischemia or perforation.
