    OLYMPUS MEDICAL SYSTEMS CORP. (OMSC) RECEIVED A LITERATURE TITLED ¿ULTRASOUND ENDOSCOPES AND ROUTINE MICROBIOLOGICAL SURVEILLANCE - ANOTHER CRITICAL DEVICE IN REPROCESSING¿. BACKGROUND: PERIODIC ROUTINE MICROBIOLOGICAL SURVEILLANCE OF GASTROINTESTINAL ENDOSCOPES IS RECOMMENDED TO ENSURE ADEQUACY OF REPROCESSING. WE AIMED TO INVESTIGATE WHETHER THERE WERE DIFFERENCES IN CONTAMINATION DEPENDING ON THE TYPE OF ENDOSCOPE. METHODS: WE ANALYZED 437 MICROBIOLOGICAL SURVEILLANCE SAMPLES OBTAINED FROM GASTROINTESTINAL ENDOSCOPES AT A TERTIARY-CARE CENTER IN SWITZERLAND. SAMPLING WAS CARRIED OUT AFTER REPROCESSING IN WASHER-DISINFECTORS ACCORDING TO STANDARD SN EN ISO 15883-4:2018. FOR MICROBIOLOGICAL ANALYSIS, ENDOSCOPE IRRIGATION SOLUTION WAS FILTERED AND TRANSFERRED TO SHEEP BLOOD AGAR. THESE PLATES WERE INCUBATED AT 37°C. IF BACTERIAL GROWTH WAS DETECTED, THE SPECIES WAS IDENTIFIED USING MALDI OR OTHER MICROBIOLOGICAL IDENTIFICATION TECHNIQUES, AND COLONY FORMING UNITS (CFUS) WERE COUNTED. CONTAMINATION WAS DEFINED AS DETECTION OF ANY MICROORGANISM WITH =20 CFUS/20 ML OR DETECTION OF ENTEROBACTERALES, ENTEROCOCCUS SPP., PSEUDOMONAS AERUGINOSA AND OTHER NON-FERMENTERS, STREPTOCOCCUS VIRIDANS AND STAPHYLOCOCCUS AUREUS, INDEPENDENT OF CFU COUNT. RESULTS: TOTALLY, 204 SAMPLES WERE GATHERED FROM 28 GASTROSCOPES, 146 SAMPLES FROM 23 COLONOSCOPES, 45 SAMPLES FROM 5 ULTRASOUND ENDOSCOPES, 27 FROM 4 DUODENOSCOPES AND 15 FROM 3 ENTEROSCOPES, RESPECTIVELY. ELEVEN (2.5%) SAMPLES, GATHERED FROM 5 ENDOSCOPES, INDICATED CONTAMINATION. THE PROPORTION OF SAMPLES INDICATING CONTAMINATION VARIED LARGELY BY ENDOSCOPE TYPE: 20.0% (9/45) OF ULTRASOUND ENDOSCOPES-DERIVED, 1.4% (2/146) OF COLONOSCOPE-DERIVED, 0.5% (1/204) OF GASTROSCOPE-DERIVED, 0% (0/27) OF DUODENOSCOPE-DERIVED AND 0% (0/15) ENTEROSCOPE-DERIVED SAMPLES WERE CONTAMINATED (P<0.001). CONCLUSIONS: OVERALL, A SMALL PROPORTION OF ENDOSCOPES WERE CONTAMINATED. SIGNIFICANT DIFFERENCES WERE OBSERVED BASED ON THE TYPE OF ENDOSCOPE, WITH ULTRASOUND ENDOSCOPES PERFORMING WORST.
