Gut 2021; 70:1629-1631. [PMID: 33408123 PMCID: PMC7789205 DOI: 10.1136/gutjnl-2020-323577] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2020] [Revised: 12/22/2020] [Accepted: 12/29/2020] [Indexed: 12/21/2022]
Abstract
The risk of SARS-CoV-2 transmission in endoscopy is not only between patients and endoscopy staff but is also through inadequately reprocessed endoscopes. There are no studies that could confirm the efficacy of current ways of endoscope reprocessing on the elimination of SARS-CoV-2. The aim of this pilot study was to evaluate the efficacy of high disinfection of endoscopes with peracetic acid on eliminating SARS-CoV-2, but surprisingly we found that the virus cannot be detected on any part of endoscopes used in critically ill patients due to SARS-CoV-2 and this was the same for all types of endoscopies and procedures. If confirmed in larger studies, these findings will probably open a new scenario in the overall understanding of the real impact of the virus.

Is Post-Reprocessing Microbiological Surveillance of Duodenoscopes Effective in Reducing the Potential Risk in Transmitting Pathogens? INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 17:ijerph17010140. [PMID: 31878150 PMCID: PMC6982321 DOI: 10.3390/ijerph17010140] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/09/2019] [Revised: 12/16/2019] [Accepted: 12/19/2019] [Indexed: 12/20/2022]
Abstract
Background: The use of a contaminated endoscope may lead to infections due to the transmission of potential pathogens from patient to patient. Methods: Post-reprocessing microbiological surveillance of four duodenoscopes was carried out over a three-year period in the Digestive Endoscopy Unit of an Italian hospital. Sampling of duodenoscopes was performed after the devices have been reprocessed. The initial phase of surveillance involved the contemporary evaluation of the four duodenoscopes; afterwards, microbiological surveillance proceeded at monthly intervals. Results: The initial phase of surveillance revealed that three duodenoscopes presented a high level of contamination with “high-concern” micro-organisms, some of which were multi-drug-resistant. The highest values of contamination regarded the species P. aeruginosa (2500 CFU/duodenoscope), K. pneumoniae (2580 CFU/duodenoscope), and A. baumannii (2600 CFU/duodenoscope). Since the cultures were repeatedly positive on three successive occasions, the contaminated devices were sent to the manufacturer for evaluation. Audits were carried out with the personnel responsible for reprocessing, which was aimed to optimize the procedures used, and subsequently, only one case of non-conformity was found. Conclusions: Our study highlighted both the potential risk of transmitting pathogens through the use of duodenoscopes and the importance of implementing a well-structured system of microbiological surveillance and training programs, in order to reduce the risk of spreading retrograde cholangiopancreatography (ERCP)-associated infections.
