Review article: endoscopy-related infections
1Division of Gastroenterology, University of Utah Medical Center, Salt Lake City 84132.
Abstract:
Endoscopic procedures generate bacteraemia to different degrees. Under certain conditions, most notably valvular heart disease, clinically significant infections may occur. A large body of literature has grown around recommendations for antibiotic prophylaxis to prevent procedure-related infections. Most of this literature is in the form of anecdotal reports. Few prospective randomized studies have been performed. In this paper, the literature on endoscopy-related infections is reviewed. Recommendations for antibiotics from different sources are compared and a rational approach to prophylactic antibiotic therapy is presented.
Insights
Endoscopic procedures can cause bacteraemia, potentially leading to infections in patients with valvular heart disease. This review examines antibiotic prophylaxis recommendations to prevent these rare but serious endoscopy-related infections.
Area of Science:
- Infectious Diseases
- Gastroenterology
- Cardiology
Background:
- Endoscopic procedures are known to cause bacteraemia.
- Clinically significant infections, particularly in patients with valvular heart disease, can arise from bacteraemia.
- Existing literature on antibiotic prophylaxis is largely anecdotal, with limited prospective randomized studies.
Purpose of the Study:
- To review the existing literature on infections related to endoscopic procedures.
- To compare various recommendations for antibiotic prophylaxis.
- To present a rational approach to prophylactic antibiotic therapy.
Main Methods:
- Literature review of endoscopy-related infections.
- Comparison of antibiotic prophylaxis recommendations from different sources.
Main Results:
- Endoscopy-induced bacteraemia varies in degree.
- Valvular heart disease is a significant risk factor for infection.
- A critical review of anecdotal reports and limited prospective data was performed.
Conclusions:
- A rational approach to antibiotic prophylaxis is needed for specific patient groups undergoing endoscopy.
- Further high-quality research is warranted to solidify evidence-based recommendations.
- Preventing rare but serious infections requires careful consideration of risk factors and prophylactic strategies.
