Acute cholecystitis in elderly and high-risk surgical patients: is percutaneous cholecystostomy preferable to emergency cholecystectomy?

Abstract

ObjectiveTo investigate whether percutaneous cholecystostomy (PC) for the treatment of acute calculous cholecystitis (ACC) has better results than emergency cholecystectomy (EC) in elderly and high-risk surgical patients. MethodsPatients ≥ 70 years and/or ≥ ASA-PS 3 with ACC treated with PC or EC between 2005 and 2016 were retrospectively reviewed. Both techniques were compared regarding morbi-mortality, hospital stay, complications and readmissions. A subgroup analysis in higher risk patients (≥ 70 years plus ≥ ASA-PS 3) was also performed. A binary logistic regression analysis for outcome variables to calculate the OR was carried out. ResultsA total of 461 patients were included in the study. The results of PC were worse compared to EC: 30-day mortality (8.6 vs. 1.7%, OR 18.4), 90-day mortality (10.4 vs. 2.1%, OR 10.3), length of stay (days) (13.21±8.2 vs. 7.48 ± 7.67, OR 8.7) and readmission rate (35.1 vs. 12.6%, OR 4.7). Complications were lower for PC (14 vs. 22.6%, OR 0.41), but there were no significant differences in the number of severe complications (Clavien-Dindo ≥ III). Higher-risk subgroup analysis (n = 193; PC = 128, EC = 65) showed similar results to the whole series. Patients with ACC for more than 3 days had more risk of severe complications in both groups (OR 2.26; OR 2.76). ConclusionPC was associated with an increased risk of mortality at 30 and 90 days, more readmissions and longer hospital stay. Although PC presents a lower risk of complications, the percentage of severe complications (Clavien-Dindo ≥ III) does not show significant differences.
