Ultrasound-guided percutaneous cholecystostomy in acute cholecystitis: case vignette and review of the technique.

Acute cholecystitis is a frequent condition. Although cholecystectomy is the indicated treatment of this entity, it cannot be performed in some high-risk surgery patients, such as critically ill or those with multiple comorbidities. In these non-uncommon scenarios, percutaneous cholecystostomy is the recommended alternative treatment, which allows immediate decompression and drainage of the acutely inflamed gallbladder and thus reducing the patient's symptoms and the systemic inflammatory response. Ultrasound is the imaging method of choice to guide the percutaneous cholecystostomy procedure due to its real-time guidance, lack of ionizing radiation and portability, avoiding the need to transfer unhealthy patients to the radiology department. We will review the ultrasound-guided percutaneous cholecystostomy procedure, of special interest for radiologists, surgeons, and also intensive care and emergency physicians.
