Objective: To 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.
Methods: Patients ≥ 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.
Results: A 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).
Conclusion: PC 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.
