Endoscope Reprocessing Effectiveness Evaluation

This study received Stanford University Institutional Review Board approval (protocol number 38212). This study was performed at the Stanford University Hospital in an endoscopy suite that performs >50 GI endoscopy procedures each day. Consecutive, patient-used endoscopes were tested for ATP bioluminescence after pre-cleaning, manual cleaning, and HLD. The endoscopes were manufactured by the Olympus Corporation of the Americas (Center Valley, Pa), including gastroscope models GIF-160, GIF-H180 and GIF-Q180, colonoscope models CF-Q180AL, CF-H180AL, PCF-160AL, PCF-H190 and PCF-Q180, echoendoscope models GF-UE160, GF-UE160-AL5 and GF-UC140, and duodenoscope model TJF-160VF, and by Pentax of America (Montvale, NJ), including gastroscope models EG-2990I and EG-3490K, colonoscope models EC-3890LI and EC-3490LI, and echoendoscope models EG-3670URK and EG-3870URK.
In the pre-intervention phase of this study, patient used gastroscopes (n=10), colonoscopes (n=10), duodenoscopes (n=10), linear echoendoscopes (n=10), and radial echoendoscopes (n=8) were tested. In the post-intervention phases, only duodenoscopes (n=10) were tested.

Colonoscopic Band Ligation of Polyps

Check if the same lab product or an alternative is used in the 5 most similar protocols

Once the decision for EMR-BLA or BLA was made, the colonoscope was removed. A band ligator (MBL-6-XL-C, or MBL-6; Cook Medical, Bloomington IN, USA) was loaded onto the scope (EG-3490K, EC-3490Li, or EC-3890Li; Pentax Medical, Tokyo, Japan) in usual fashion. The image magnifier option was used to magnify the image and limit the impact of the cap blocking the peripheral endoscopic view. The image was enhanced using the i-scan 1 option (surface enhancement) on the Pentax Processor (EPK-i7010; Pentax Medical) to offset the almost universal slight blurriness that appeared to occur while using a scope with a banding kit loaded on it in the colon. Band deployment was performed in standard fashion by suctioning the area of interest/polyp into the cap and releasing the band upon achieving maximum tissue in the cap (read out on screen). The examination was then terminated, and the bands were left attached to allow for gradual amputation.

Insufflator Temperature During Colonoscopy

Check if the same lab product or an alternative is used in the 5 most similar protocols

An ex-vivo study was performed investigating the temperature of carbon dioxide delivered from three commercially available insufflators [Olympus CO
₂Regulation Unit UCR (Olympus Canada Inc., Richmond Hill, Ontario, Canada), Medivators EndoStratus EGA-501 (Medivators Inc., Minneapolis, MN), and EZEM-CO
₂efficient (Bracco Diagnostics Inc., Monroe Township, NJ)]. Using two adult colonoscopes (Olympus CF-H180DL and Pentax EC-3890Li) with their lights on, the air button was continuously depressed. Temperatures were recorded at both the insufflator end and distal colonoscope end for 10 minutes, in increments of 1 minute. Ten minutes was chosen to replicate an average cecal intubation time. For each colonoscope and insufflator, experiments were performed both at room temperature and with the body of the colonoscope immersed in a warm water bath, maintained at 34
°C, to replicate the colonoscope inside the colon.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
