Potential transmission of pathogenic microorganisms associated to gastroscopes in costa rica

Background: Flexible gastrointestinal endoscopes (gastroscopes) have been associated with patient infections and outbreaks, especially because of the high contamination they suffer during procedures. The aim of this investigation was to evaluate the presence of diverse bacteria, including pathogens on the surface of endoscopes before their use on patients having an Esophagogastroduodenos copy (EGD). Methods: 68 different gastro scopes used at a type A hospital in San José, Costa Rica, were analyzed in order to determine the presence of different bacteria that might potentially infect patients. The external surface of the insertion tube was analyzed before its introduction into the patient. Also, the disinfecting agent used was microbiologically tested. Results: The results obtained showed an important contamination of the gastro scopes with potentially infectious agents. The disinfectant solution, after 30 days of use also showed microbiological contamination. Conclusions: an important rate of contamination of gastro scopes with different bacteria, including potential pathogens was found. Additional efforts must be done to assure proper procedures for the cleaning and disinfection of this equipment in order to offer patient safety and diminish potential infections.
