Background: The aim of the study was to describe the microbiology and susceptibility patterns in acute cholecystitis by examining bile culture results from patients who underwent percutaneous cholecystostomy and examine concordance with empiric treatment. Patients and Methods: A total of 124 patients with acute cholecystitis underwent percutaneous cholecystostomy between 2003 and 2012 at Emek Medical Center, Israel. Data on bile and blood culture results, isolate susceptibility, and clinical outcomes were retrieved from patient files. Results: Bile cultures obtained from 116 patients were positive in 70 (60.3%) patients. Blood cultures obtained from 77 patients were positive in 23 (31.1%). Escherichia coli was the most common isolate in 28.6% of bile cultures and 43.5% of blood cultures. The concordance between empiric treatment coverage and culture isolate susceptibility was 67.6%. In most discordant cases, the isolates were Enterobacter spp. (40.9%) and Enterococcus spp. (31.8%). Overall, the in-hospital mortality rate was 7%: 2% in patients with concordant treatment compared with 14% in patients with discordant treatment (p = 0.09). Empiric antibiotic regimens were adequate in only two-thirds of patients. Conclusions: There might be a trend for poorer outcome in patients treated with inadequate antibiotic agents, emphasizing the importance of tailoring antibiotic treatment.
