Impact of Remote Cholecystectomy on Clinical Outcomes Following

Background: Mortality associated with Methods: We conducted a retrospective cohort study of adults hospitalized over a 5-year period with PABSI. PABSI cases were defined as patients with ≥1 positive Results: The overall study population included 336 patients: 262 (78%) with a retained gallbladder and 74 (22%) without. Using the entire study population and a matched cohort, we observed no difference in length of culture positivity, 90-day mortality, or in-hospital mortality between groups based on the presence of a gallbladder. Overall, composite 90-day mortality was 30.1%, which was similar to a prior investigation of PABSI outcomes at our institution. While the presence of a gallbladder did not affect the outcome, patients with PABSI and liver disease had significantly higher 90-day mortality than those without liver disease. Furthermore, no robust differences were observed in the antimicrobial resistance profile of Conclusions: In our study, neither PABSI antimicrobial resistance pattern nor clinical outcomes were affected by remote cholecystectomy. However, we do demonstrate that mortality for patients with PABSI in the modern era remains high despite advances in antipseudomonal therapeutics.
