Percutaneous Cholecystostomy Versus Conservative Treatment for Acute Cholecystitis: a Cohort Study

Background Percutaneous cholecystostomy is frequently used as a treatment option for acute calculous cholecystitis in patients unfit for surgery. There is sparse evidence on the long-term impact of cholecystostomy on gallstone-related morbidity and mortality in patients with acute calculous cholecystitis. This study describes the long-term outcome of acute calculous cholecystitis following percutaneous cholecystostomy compared to conservative treatment. Methods This was a cohort study of patients admitted at our institution from 2006 to 2015 with acute calculous cholecystitis without early or delayed cholecystectomy. Endpoints were gallstone-related readmissions, recurrent cholecystitis, and overall mortality. Results The investigation included 201 patients of whom 97 (48.2%) underwent percutaneous cholecystostomy. Patients in the cholecystostomy group had significantly higher age, comorbidity level, and inflammatory response at admission. The median duration of catheter placement in the cholecystostomy group was 6 days. The complication rate of cholecystostomy was 3.1% and the mortality during the index admission was 3.5%. The median follow-up was 1.6 years. The rate of gallstone-related readmissions was 38.6%, and 25.3% had recurrence of cholecystitis. Cox regression analyses revealed no significant differences in gallstone-related readmissions, recurrence of acute calculous cholecystitis, and overall mortality in the two groups. Conclusions Percutaneous cholecystostomy in the treatment of acute calculous cholecystitis was neither associated with long-term benefits nor complications. Based on the high gallstone-related readmission rates of this study population and todays perioperative improvements, we suggest rethinking the indications for non-operative management including percutaneous cholecystostomy in acute calculous cholecystitis.
