The EndoCuff is novel flexible cuff that can be attached to the distal tip of the colonoscope and helps to flatten large mucosal folds during withdrawal.

The study hypothesis is that the use of the Endocuff (EC) increases the adenoma detection rate during colonoscopy.

The study purpose is to compare EC-assisted colonoscopy with standard colonoscopy for polyp detection.

Primary Outcome Measures:
  • adenoma detection rate [ Time Frame: 25 minutes ] [ Designated as safety issue: No ]
    completion of colonoscopy is defined as the time point at which the colonoscope has been pulled out of the body.

Secondary Outcome Measures:
  • polyp detection rate [ Time Frame: 1 Week ] [ Designated as safety issue: No ]
  • number of LGIN and HGIN adenomas detected [ Time Frame: one week ] [ Designated as safety issue: No ]
    LGIN= low grade intraepithelial neoplasia HGIN= high grade intraepithelial neoplasia

  • polyp distribution [ Time Frame: 25 minutes ] [ Designated as safety issue: No ]
  • procedure time [ Time Frame: 25 Minutes ] [ Designated as safety issue: No ]
  • withdrawal time [ Time Frame: 10 Minutes ] [ Designated as safety issue: No ]
    without intervention time due to polypectomy

  • ileum intubation rate [ Time Frame: 10 minutes ] [ Designated as safety issue: No ]
  • total colonoscopy rate [ Time Frame: 25 minutes ] [ Designated as safety issue: No ]
  • adverse events [ Time Frame: 25 minutes ] [ Designated as safety issue: Yes ]
    perforation, cuff loss, lacerations, major bleedings, drop of sO2 during colonoscopy
