Abstract
Acute cholecystitis (AC) is a common emergency condition with severity ranging from mild to severe. Gallstones and critical illnesses are the common predisposing factors. Mild AC is primarily managed with medical therapy and early cholecystectomy. Moderate and severe AC require individualized treatment with a preference for early cholecystectomy. However, cholecystectomy may not always be feasible due to co-morbidities. Hence, this group of patients needs minimally invasive methods to drain the gallbladder (GB). Percutaneous cholecystostomy (PC) is the image-guided drainage of GB in the setting of moderate to severe AC. There are different approaches to PC. The technical aspects, success, and complications of PC as well as management of cholecystostomy catheter after the patient recovers from the acute episode should be thoroughly understood by the interventional radiologist. We present an extensive up-to-date review of the essential aspects of PC including indications, contraindications, techniques, and outcomes, including complications and success rates.
