Subdiaphragmatic free air cannot originate in the biliary tract, and if present, it indicates another disease process. Gas limited to the gallbladder wall or lumen represents emphysematous cholecystitis, usually because of gas-forming bacteria, such as Escherichia coli and clostridial and anaerobic streptococci species. Emphysematous cholecystitis is associated with increased mortality and occurs most commonly in males with diabetes and with acalculous cholecystitis.
