    Abstract:
    Endoscopy is a diagnostic and therapeutic method which is being increasingly used in various fields of medicine, especially in minimal invasive surgery. During the endoscopic procedure, endoscopes are contaminated with patient's microbial flora. After each procedure and before the next patient, endoscope should be reprocessed in a way to be safe from post-procedural infection. Endoscopes are divided in two categories (the borders between them are not always clear-cut): high-risk category endoscopes which enter the sterile tissue, and medium-risk category which come in contact with mucosal surface. High-risk endoscopes should be sterilized or high-level disinfected, and medium-risk should be high-level disinfected. The first and the most important step in endoscope reprocessing is thorough manual cleaning of all parts of dismantled endoscope and of all channels in water and (enzymatic) detergent. The second step is disinfection of endoscope fully immersed in 2% glutaraldehyde for 20 minutes at room temperature. The third step is thorough rinsing in sterile water or tap water followed by 70% ethanol, depending on the next endoscopic procedure. Steps 2-4 can be done in the machine. During endoscopy as well as during endoscope reprocessing, strict preventive measures should be followed for health care workers protection.
