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.
Interventions
colonoscopes equipped with ScopeGuide
ScopeGuide's 3D visualisation screen
