In this episode of MedDevice by Design, Ariana and Mark examine the complexities of endoscope reprocessing, one of the most difficult tasks in medical device hygiene. These devices contain intricate internal channels and delicate mechanisms that make both cleaning and disinfection incredibly labor-intensive. With endoscopes routinely used in clinical settings, ensuring they are safe to reuse is critical for patient safety and operator health.

Why Endoscopes Are So Hard to Clean

Mark explains that endoscopes are inserted into particularly contaminated environments and are often constructed from materials that cannot withstand high temperatures. This makes steam sterilization ineffective. Instead, hospitals rely on high-level disinfection—an extensive manual and automated cleaning process that includes enzymatic scrubbing, flushing internal ports, leak testing, and finally, drying and hanging.

Innovations in Endoscope Cleaning

To streamline this complex process, manufacturers have developed new automated solutions. The Steris Inspire 300, for instance, eliminates the need for manual cleaning between bedside wipe-down and automated disinfection. Other innovations include the Pentax Aqua Typhoon and Nanosonics Coris, which use entrapped bubbles or pulsatile flow to clean hard-to-reach channels. These advances aim to reduce the physical burden on staff while improving the reliability of endoscope reprocessing outcomes.

Is It Really Safe?

While current reprocessing methods report an adverse event rate of just 1 in 1.8 million, the challenge lies in consistent execution. Missed steps and usability challenges can introduce risk, despite the devices being considered technically safe. That’s why innovations in automated systems are so important—they minimize human error and optimize hygiene.
