Brief Summary:
This study seeks to compare colonoscopy results between a standard method and one using a distal scope attachment (Endocuff Vision).

Condition or disease Intervention/treatment Phase
Colorectal Polyp Colorectal Adenoma Colon Cancer Device: Endocuff Vision Not Applicable

Detailed Description:
For this study, subjects will be randomized into one of two groups (those who receive a standard colonoscopy and those who receive a colonoscopy with an Endocuff Vision attachment). Results will then be compared between the two; these include insertion time (time it takes to reach the cecum of the large intestine), inspection time (time spent examining the large intestine), the total time per each polypectomy (removal of polyps in the colon), and the total procedure time of the colonoscopy.

Arm Intervention/treatment
No Intervention: Control Arm (Standard Colonscopy)
Standard colonoscopy with no device attachments
Experimental: Endocuff Vision
Colonoscopy with Endocuff Vision attached to distal end of scope
Device: Endocuff Vision
Subjects that are randomized to undergo their colonoscopy procedure with the Endocuff Vision device will have the device placed on the colonoscope that will be used during their procedure.




Primary Outcome Measures :
  1. Inspection Time Comparisons for Each Method (Standard vs. Endocuff Vision) [ Time Frame: During the withdrawal portion of the colonoscopy procedure ]
    Inspection time is time spent actually examining the colon. This was measured with a stopwatch and calculated by subtracting washing, suctioning, polypectomy and biopsy times from total withdrawal time. It was measured during colonoscopy by a study assistant using a stopwatch.


Secondary Outcome Measures :
  1. Insertion Time Comparisons for Each Method (Standard vs. Endocuff Vision) [ Time Frame: During the insertion portion of the colonoscopy procedure ]
    Insertion time is the time it takes from the colonoscope first being inserted to when the furthest section of the colon (which is called the cecum) is reached.

  2. Total Procedure Time Comparisons for Each Method (Standard vs. Endocuff Vision) [ Time Frame: During the colonoscopy procedure ]
    Total procedure time is the time from the initial insertion through the complete withdrawal of the scope

  3. Detection Rates [ Time Frame: During the colonoscopy procedure ]
    The percentage of participants with at least one of the indicated polyp types found during standard colonoscopy compared to colonoscopy with Endocuff Vision.

  4. Polyps Per Colonoscopy [ Time Frame: During the colonoscopy procedure ]
    Number of adenomas or sessile serrated polyps found per colonoscopy of Standard colonoscopy compared to Colonoscopy with Endocuff Vision.

  5. Boston Bowel Preparation Score [ Time Frame: During the withdrawal portion of the colonoscopy procedure after cleaning of the colon ]

    Boston Bowel Preparation Score for patients receiving standard colonoscopy compared to colonoscopy with endocuff vision.

    The total score for the Boston Bowel Preparation Scale ranges from 0 to 9, with higher score indicating a better bowel preparation quality.

    The quality of the bowel preparation is assessed by the attending gastroenterologist.
