Introduction: The endoscope is a medical procedure used for diagnosis and treatment of gastrointestinal diseases which requires a proper cleaning and disinfection/sterilization to prevent the spread of microorganisms associated with the reuse of endoscopes in patients. Nearly 300 cases of complications of infections involve bacteria, viruses and fungi, highlighting the bacteria Helicobacter pylori that is a risk factor for gastric and duodenal ulcer, which may lead to cancer of the stomach. Objective: to search and evaluate scientific evidence on the disinfection of gastrointestinal endoscopes using glutaraldehyde (GTA) to 2.0%. As a criterion inclusion was set up all articles with language in english, spanish and portuguese. Methods: This is an integrative review in databases Medline/PubMed and ISI Web of Knowledge in the last five years. Results: From sixteen publications, only eight was related to above criteria. As the results analyzed, showed reduction of 99.9% of Tropheryma whipplei in disinfection of gastrointestinal endoscopes with glutaraldehyde to 2.0% which was found in only one publication. T.whipplei the bacteria causes a rare and chronic disease that affects the intestines, central nervous system and heart with symptoms of fever, diarrhea, weight loss and abdominal pain. Two publications were comparative studies between GTA to 2.0%, chlorhexidine gluconate to 4.0% and electrolyzed acid water. The five analyzed publication on the effectiveness of glutaraldehyde to 2.0% in the decontamination of flexible endoscopes. Conclusions: The publications analyzed, level II, III and VI, they explained on the risk of infections by Staphylococcus aureus, Pseudomonas aeruginosas and biofilm in gastrointestinal endoscopes and the widespread use is made of various health services difficult making of decision for their replacement.
