Microbiological Characteristics of Pathogens Isolated From Blood Cultures of Patients With Acute Cholangitis: Insights From Patients With Biliary-Enteric Anastomosis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundWe aimed to investigate the microbiological characteristics of pathogens isolated from blood cultures (BCs) of patients with acute cholangitis (AC) after biliary-enteric anastomosis and biliary intervention (BI).
methodsA retrospective analysis was conducted on 366 patients with AC and bacteremia between 2015 and 2024 at Hiroshima University Hospital. Patients were categorized into three groups: post-biliary reconstruction-associated AC (PBR-AC), BI-associated AC (BI-AC), and common AC (C-AC). Patients' clinical and microbiological data were statistically analyzed in each group.
resultsThe most frequently isolated pathogens were Escherichia coli and Klebsiella spp., accounting for > 50% of isolates in all groups. ESCPM spp. (Enterobacter spp., including Klebsiella aerogenes, Serratia marcescens, Citrobacter freundii complex, Providencia spp., and Morganella morganii) were significantly associated with PBR- and BI-AC compared with C-AC. No significant differences in the prevalence of anaerobic bacteria were observed among the groups.
conclusionsThe prevalence of ESCPM spp. isolated from BCs was significantly higher in the PBR- and BI-AC groups than in the C-AC group. The presence of biliary-enteric anastomosis or BI history should be checked when determining the treatment strategy for AC. Cefepime may be a better antibiotic option for PBR- and BI-AC, particularly in severe cases.
