Cholecystectomy is the standard treatment of acute cholecystitis. Surgery, however, poses significant risks for patients with advanced age and/or comorbid conditions. For such patients, percutaneous cholecystostomy (PC) is the only option. This interventional procedure does not have any absolute contraindications because of the life-threatening nature of the disease, in which other treatment options cannot be offered due to their risks. Nonetheless, these risk factors necessitate performing PC under urgent, rapid, and in many cases suboptimal conditions. In this article, PC was revisited in the light of our extensive experience in addition to the most current literature. Pre-procedural evaluation including the risk assessment and procedural steps was presented in detail. If conducted properly, PC provides significant clinical improvement in the short term and is life-saving, especially in the elderly and in patients with comorbid diseases or high surgical risk. It may also be the definitive treatment method for acute cholecystitis. (NCI-2021-1-50/R1)Keywords: Cholecystitis, cholecystostomy; gallbladder; interventional procedure.
