Overview
Infection of esophageal antireflux devices (e.g., Stretta, EsophyX) is a rare but serious complication that can occur due to inadequate sterilization or biofilm formation, potentially leading to device-related infections and impaired efficacy 1.Diagnosis
Microbial cultures from device surfaces and patient samples (e.g., blood, sputum) may be necessary to identify pathogens 1.
Clinical signs include persistent symptoms of GERD worsening, fever, or signs of systemic infection 1.Management
Removal and replacement of the infected device 1.
Appropriate antibiotic therapy based on culture and sensitivity results 1.
Enhanced sterilization protocols for reprocessing devices post-infection 1.Special Populations
No specific data provided in the abstracts regarding pregnancy, pediatrics, elderly, or comorbidities related to infection of esophageal antireflux devices 1.Key Recommendations
Utilize disposable sterile sheaths to reduce the risk of bacterial contamination during endoscopic procedures, potentially minimizing the need for high-level disinfection 1 (Evidence: Moderate).
Implement rigorous post-procedure cleaning and disinfection protocols, such as enzymatic cleansing followed by 70% ethanol disinfection, to maintain device sterility 1 (Evidence: Moderate).
In cases of suspected infection, promptly remove the device and initiate targeted antibiotic therapy guided by microbiological findings 1 (Evidence: Strong).References
