acalculous cholecystitis

acalculous cholecystitis
any cholecystitis that is not caused by gallstones. These types constitute not more than 10 per cent of cases but usually have a much more grave prognosis than calculous cholecystitis because there may be serious complications such as gangrene and perforation. Acalculous types are usually secondary to bile duct obstruction and biliary stasis, and many of the patients are already severely ill or injured from some other condition, such as a severe burn, sepsis, or other trauma.
