Percutaneous cholecystostomy and acute cholecystitis: how, when and why.

AIM: Acute cholecystitis (AC) is one of the most frequent pathologies treated in urgency. An immediate surgical intervention for frail patients who are ineligible for surgery as a result of severe co-morbidities is questionable. The aim of this study is to investigate the safety and the management of percutaneous cholecistostomy (PC) in high-risk surgical patients. MATERIALS AND METHODS: In the period of time January 2015 - May 2021 we observed 1105 patients admitted with acute cholecystitis in our Department. In the group with severe cholecystitis (160 patients, 14.48%), 137 (12.39%) were submitted to immediate surgery, and 23 (4.8%) were treated with PC. All these patients were non-responding to conservative management. Initially, we used PC as a definitive treatment; from the second half of 2018 PC was implemented as a bridge to surgery. RESULTS: Clinically, symptoms resolved in all the 23 patients. Mortality was nihil and no complication was recorded. PC was used as definitive treatment in 14 cases, wheres in 9 patients PC was intended as a-bridge-to-surgery treatment, and was followed by cholecystectomy. DISCUSSION: 2017 guidelines, of World Society of Emergency Surgery recommended PC as a safe and effective management of AC in patients with multiple comorbidities. In this group of patients PC achieves a prompt resolution of clinical symptoms and is superior to conservative management. There are no absolute contraindications to PC. CONCLUSIONS: PC is a safe and less invasive treatment of AC for patients with prohibitive surgical risk. It may be used as bridge to surgery to switch high-risk for moderate-risk patients, more suitable for a safe and definitive surgical treatment.
