A diabetic patient presents with RUQ pain and ultrasound shows gas within the wall of the gallbladder. What is the likely diagnosis and recommended management?

• A. Acute calculous cholecystitis treated with antibiotics and analgesia
• B. Emphysematous cholecystitis with broad-spectrum antibiotics and fluids started immediately, followed by urgent cholecystectomy due to risk of gangrene
• C. Cholangitis managed with antibiotics only
• D. Cholelithiasis without infection

Answer: (B)

Gas in the gallbladder wall in a diabetic patient points to emphysematous cholecystitis, a gas-forming infection that makes the gallbladder tissue prone to rapid necrosis and perforation. This is much more dangerous than typical acute cholecystitis because the gas-forming organisms and poor tissue perfusion can progress quickly to gangrene.

Because of this aggressive course, management must be immediate and decisive: start broad-spectrum IV antibiotics that cover anaerobes and enteric Gram-negatives, and give aggressive IV fluids. The definitive step is urgent cholecystectomy after the patient is stabilized to remove the source of infection and prevent further necrosis or perforation. If the patient cannot tolerate immediate surgery, a percutaneous cholecystostomy can be used as a bridge, but definitive treatment remains removal of the gallbladder. This situation differs from uncomplicated cholelithiasis or standard cholangitis, where antibiotics alone or biliary decompression, respectively, would be insufficient without addressing the diseased gallbladder.
