Summary
Current cephalosporin prophylaxis for interventional radiologic biliary procedures may be inadequate. Enterococcus species were the primary cause of bloodstream infections, suggesting a need to reevaluate prophylaxis guidelines for these procedures.
Area of Science:
- Interventional Radiology
- Infectious Diseases
- Biliary Medicine
Background:
- Interventional radiologic biliary procedures are common.
- Bacteremia is a potential complication.
- Prophylaxis guidelines exist but may need review.
Purpose of the Study:
- To evaluate the effectiveness of antibiotic prophylaxis for interventional radiologic biliary procedures.
- To identify the causative organisms of bloodstream infections following these procedures.
Main Methods:
- Retrospective analysis of 148 patients undergoing 480 interventional radiologic biliary procedures.
- Evaluation of bloodstream infection evidence, antibiotic use, and infectious complications.
- Analysis of pre- and post-procedure bile and blood cultures.
Main Results:
- Seven cases of bloodstream infection were identified, with Enterococcus species being the most common pathogen.
- Infections primarily occurred in patients with recent biliary surgery or complex manipulations.
- Bile colonization was linked to older age, and positive bile cultures increased infection risk.
Conclusions:
- Current cephalosporin prophylaxis recommendations for interventional radiologic biliary procedures may require reevaluation.
- The role of Enterococcus species in post-procedural bacteremia warrants further investigation.
