title: Acalculous cholecystitis: its role as a complication of major burn injury.
abstract: The authors present four cases of acute acalculous cholecystitis complicating major burn injury and review the recent literature on acalculous cholecystitis. All patients were men and ranged in age from 22 to 40 years. The mean extent of the burn was 50% of the total body surface area, with an average 29% third-degree component. All four patients survived. Because of their severity, major burn injuries expose patients to many risks, including acute acalculous cholecystitis. Recent experimental evidence supports a vascular insult through the activation of Factor XII pathways as the initial event. A diagnosis is made on clinical grounds, supported by laboratory and ultrasonographic findings, in a patient with a burn covering more than 30% of the total body surface area and who has signs of acute cholecystitis. Cholecystectomy is the treatment of choice; tube cholecystostomy is reserved for critically ill patients.
