Comparisons of Endo-Wing-assisted Colonoscopy Versus Standard Colonoscopy in Improving Adenoma Detection Rate in Symptomatic Patients Suspected of Colorectal Cancer

Endo-Wing™ (Shangxian Minimal Invasive Inc, China) is a medical-grade soft silicone rubber device that is attached at the end of a colonoscope. It has 6 soft wing-like projections that are bendable and pliable, giving the endoscopist a superior visualization directly from its action of flattening the colonic folds and maintaining the central view of the colonoscope during withdrawal. This can improve the endoscopist's ADR.

Colonoscopies performed using Olympus Evis Exera III 90 series or Olympus Evis Lucera 260 series colonoscopes without Endo-Wing attached at the tip of the colonoscope
