Overview
Pathophysiology
Acute cholecystitis
Cholecystitis is caused by obstruction of bile duct due to impaction of gall stone[1] . Gall stone impaction leads to damage to mucosal surface of gall bladder and bile stasis. Factors which induce cholecystits are
- Lithogenic bile
- Duct obstruction
Acute inflammation is not always necessary for the development of acute cholecystitis.
Chronic Cholecystitis
There are few studies suggesting role of pancreatic biliary reflux as a co factor for the development of chronic cholecystitis. Occult pancreatic biliary reflux can be diagnosed by measuring levels of biliary amylase levels. [2]
Acute Acalculous Cholecystitis
- Gallbladder ischemia/reperfusion injury
- Prolonged periods of ischemia to gall bladder leads to disruption of normal mucosal surface.
- Lipopolysaccharides are exposed leading to activation various coagulation cascades.
- Reperfusion leads to increase humoral response which leads to further damage causing cholecystitis.
Pathology
- Chornic cholecystitis
