Borescopes are useful tools for inspecting endoscope channels and interior components, which are otherwise obscured due to being narrow and encased in opaque material. Their use is now recommended in many reprocessing guidelines. Our research team has conducted several studies on endoscope reprocessing effectiveness, during which we performed hundreds of borescope exams on a diverse array of endoscopes, including ureteroscopes, cystoscopes, bronchoscopes, endobronchial ultrasound endoscopes, gastroscopes, colonoscopes, duodenoscopes, and endoscopic ultrasound endoscopes. The interior architecture of various brands and models is diverse, with strikingly different appearance.
