Duodenoscope Sheath Protects High-Risk End of Instrument
Bret T. Petersen, MD, FASGE, reviewing Pasricha PJ, et al. Gastrointest Endosc 2020 Mar 6.
The risk of transmission of microorganisms by contaminated duodenoscopes remains a pertinent concern for ERCP practices. This report describes microbial challenge studies in a single-use device recently cleared by the Food and Drug Administration (FDA). The device, analogous to a condom, appears to effectively prevent “outside-in” microbial contamination of the high-risk elevator region and the leading end of the endoscope and device channel. The same device also provides “inside-out” protection by sealing in existing contaminants, preventing potential transmission to the patient. Bench studies confirmed that mechanical and optical performance of the endoscope was not compromised by the device.
