Discussion:

Acute cholecystitis is the main complication of gallstones and is a common cause of acute right upper quadrant pain. While the vast majority are associated with gallstones, 5-10% of cases are due to acalculous cholecystitis. As in this case, if there are no gallstones, the diagnosis of acute acalculous cholecystitis can be suggested if there is gallbladder wall thickening and surrounding edema (Fig. 1-2). Adjacent fluid, abscess, and positive ultrasonographic Murphy sign may also be present. Severe trauma, critical illness, burn, diabetes, malignant disease, abdominal vasculitis, congestive heart failure, cholesterol embolization, shock, and cardiac arrest are all associated with acute acalculous cholecystitis. 

The most common indication for percutaneous cholecystostomy is with cases of known cholecystitis -either calculous or acalculous- in patients who are too high risk for surgery. However, the procedure should be considered in critically ill patients with unexplained sepsis. Complications of the procedure include bile leak, bleeding, and bowel injury. The most common cause of bile leak and recurrent sepsis is catheter dislodgement, which is why it is advised to coil the tube inside the gallbladder if possible.
