Efficacy of Magnetic Imaging Colonoscopy Applied to Beginner Endoscopists
Study Details
Study Description
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.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: Group that does not use the scopeguide screen The control group should remove the looping of colonoscope by looking at the general colonoscopy screen The control group cannot use scopeguide screen Scopeguide screen is blinded by an opaque wrapping paper |
Device: ScopeGuide Navigated Colonoscope
colonoscopes equipped with ScopeGuide
|
| Experimental: Group using the scopeguide screen The experimental group uses a general endoscopic image during colonoscopic insertion The experimental group should remove the looping of colonoscope by looking at the scopeguide screen |
Device: ScopeGuide Navigated Colonoscope
colonoscopes equipped with ScopeGuide
Device: Navigation screen
