Core Tip

Core tip: ScopeGuide is a magnetic imaging technology designed to improve colonoscopy performance and tolerability for patients by enabling visualization of loop formation and endoscope position. Previous studies have demonstrated a useful benefit of imaging-assisted colonoscopy in procedures performed by trainees. In this randomized, controlled trial we demonstrated that when colonoscopy is performed by experienced endoscopists, the use of ScopeGuide conferred no advantage over conventional colonoscopy in terms of patient comfort, sedation requirements, and endoscopic metrics such as cecal intubation rate or time-to-cecum. However, significantly faster times-to-cecum were achieved when using ScopeGuide in more challenging cases.
