Efficacy of Magnetic Imaging Colonoscopy Applied to Beginner Endoscopists
- Conditions
- Colonic Neoplasms
- Interventions
- Device: ScopeGuide Navigated ColonoscopeDevice: Navigation screen
- Registration Number
- NCT05746962
- Lead Sponsor
- Korea University Anam Hospital
- Brief Summary
Magnetic endoscopic imaging (scopeguide) is known to be helpful for colonoscope insertion, especially beginner endoscopist. In this trial, study was designed to show the efficacy and safety pertinent to scopeguide use in detail.
- Detailed Description
Colorectal cancer is one of the most commonly diagnosed malignancies worldwide. Colorectal cancer screening significantly reduced the incidence and mortality, and colonoscopy is generally recognized as a standard method. Among them, magnetic endoscopic imaging (MEI, Scopeguide, Magnetic Enhanced Instrument, Olympus, Japan) is a non-radiological imaging instrument that can display the three-dimensional configuration and position of the colonoscope in the abdominal cavity in real time. This study aims to investigate the effectiveness of colonoscopy by measuring the insertion-related index of the colonoscopy according to the scope guide for only beginners of endoscopy.

- Primary Outcome Measures
Name Time Method proportion of colonoscope loop formation the time from the insertion of the colonoscope tip into the anal verge until reaching the cecum proportion of colonoscope loop formation
- Secondary Outcome Measures
Name Time Method loop removal during colonoscope insertion and after cecum arrival of colonoscope success or failure of loop removal
endoscopists satisfaction (questionnaire) during whole colonoscopy examination assessment for maneuverability and difficulty score about insertion through the examination
solving time for loop reduction during colonoscope insertion, from the time that recognizes the loop and tries to resolve the looping of colonoscope to the time that completely resolved the colonoscope looping solving time for loop reduction
withdrawal time the time during withdrawal of the colonoscope towards the anus withdrawal time (=examination time - cecal intubation time)
application of pressure the time from the insertion of the colonoscope tip into the anal verge until reaching the cecum nurse assissted abdominal pressure

patients satisfaction (questionnaire) during whole colonoscopy examination assessment for pain score through the examination
evaluation of risk factors about loop formation during whole colonoscopy examination factors that make a colonoscope loop
cecal intubation rate cecal intubation time and rate the time from the insertion of the colonoscope tip into the anal verge until reaching the cecum success rate of cecal intubation
variance of blood pressure during whole colonoscopy examination variance of blood pressure
adverse events during whole colonoscopy examination bleeding, perforation, and mucosal abrasion during colonoscopic exam
loop type the time from the insertion of the colonoscope tip into the anal verge until reaching the cecum loop type
loop location the time from the insertion of the colonoscope tip into the anal verge until reaching the cecum loop location
