Duodenoscope manufacturers failed to report infections

Manufacturers of closed channel duodenoscopes failed to report superbug infections linked to their devices to the authorities, according to a US Senate report released this week.

“These outbreaks occurred despite the fact that the manufacturer of 85% of the duodenoscopes used in the United States, Olympus, was aware by early 2012 that its closed-channel duodenoscope could harbor dangerous bacteria even after repeated and careful cleaning according to instructions,” the report authors write.
