Abstract
Acute cholecystitis is frequently encountered in daily clinical practice, and early cholecystectomy is the standard therapy. In high‐risk surgical patients, such as those with advanced age, deteriorated performance status, or underlying diseases, conservative treatment is typically preferred to manage acute cholecystitis. However, in patients with a disease that is refractory to conservative treatment, drainage procedures are necessary to control the infection. At present, there are three basic approaches for gallbladder drainage: percutaneous transhepatic gallbladder drainage, endoscopic transpapillary gallbladder drainage, and endoscopic ultrasound gallbladder drainage. Each of these methods has advantages and disadvantages. Therefore, the appropriate treatment method is determined on a case‐by‐case basis, and no consistent strategy for gallbladder drainage has been established. This review aimed to summarize the characteristics of each drainage method and compare the clinical outcomes of the three procedures for acute cholecystitis in high‐risk surgical patients.
