Primary Outcome Measures:
  • cap-assisted colonoscopy compared visibility with standard colonoscopy [ Time Frame: 4 months ] [ Designated as safety issue: No ]
    Propose to perform a randomized controlled trial comparing cap-assisted colonoscopy with the standard colonoscopy to assess visibility. To see if it is easier to detect polyps, adenomas with the cap than without. This is standard procedure. Just comparing if it is better to use the cap during colonoscopy.


Secondary Outcome Measures:
  • Polyp detection rate [ Time Frame: 4 months ] [ Designated as safety issue: No ]
    Number of Polyps detected per procedure using the cap. To see if it is more visible.

  • Adenoma Detection [ Time Frame: 4 months ] [ Designated as safety issue: No ]
    number of adenomatous polyps detected per procedure. To see if it is more visible using the cap as to not using the cap.

  • Advanced lesion detection rate [ Time Frame: 4 months ] [ Designated as safety issue: No ]
    (number of advanced lesions per procedure) defined as lesions with high-grade dysplasia, greater than 1 cm. size. To see if it is more visible using the cap as to not using the cap.

  • Cecal Intubation Rate [ Time Frame: 4 months ] [ Designated as safety issue: No ]
    Time to cecum

  • Total time for colonoscopy [ Time Frame: 4 months ] [ Designated as safety issue: No ]
  • Complication Rate [ Time Frame: 4 months ] [ Designated as safety issue: No ]
    Amount of complications during colonoscopies

  • Procedure indication [ Time Frame: 4 months ] [ Designated as safety issue: No ]

Estimated Enrollment: 400
Study Start Date: June 2010
Estimated Study Completion Date: September 2011
Estimated Primary Completion Date: July 2011 (Final data collection date for primary outcome measure)
Groups/Cohorts
Cap Assisted Colonoscopy
Patients receiving colonoscopies where scope is fitted with cap
Standard Colonoscopy
Patients receiving standard colonoscopy without the cap on the scope

Detailed Description:

To see if Colonoscopy with the CAP is able to give more visibility and to see if detection rate for adenomas, polyps are easier to detect.
