The Occurrence and Prevention of Infections Associated with Gastrointestinal Endoscopy.
In the four decades since the introduction of flexible endoscopy into medical practice, nearly 300 cases of human infections or pseudoinfections involving bacteria, fungi, parasites, and viruses have been linked to endoscopic procedures. In the majority of such cases, inadequate cleaning and disinfection techniques during the reprocessing of the instruments or their accessories have been likely contributing factors. Working groups from major gastroenterology societies and infection control organizations have established standards of care for the routine maintenance of endoscopic equipment in order to decrease the rates of infection even further. Since the institution of these standards, rates of transmission of infections to patients have decreased, though have not been completely resolved. This article reviews the available literature on transmission of pathogenic agents through endoscopic procedures, summarizes the current guidelines for the care of endoscopic equipment, and discusses available preventive measures aimed at decreasing the risk of endoscopy-related infections.
