NCT02665741

Brief Summary

The goal of this study is to compare two FDA approved distal colonoscope attachment devices, in order to identify which device can increase adenoma detection rate the most without increasing procedure time or risk.

    The investigators will compare adenoma detection rate at completion of study across the 3 arms

    Completion of procedure

Secondary Outcomes (3)

  • Proximal Adenoma Detection Rate

    Completion of procedure

  • Cecal Intubation Rate

    Completion of procedure

  • Withdrawal Time

    Completion of procedure

Study Arms (3)

Control

  • Age less than 50 years
  • Prior history of colon cancer
  • Patients with inflammatory bowel disease
  • Patients suspected to have colon cancer based on non invasive tests such as stool tests for hemoglobin or DNA, or imaging finding suggestive of colon cancer (CT or barium enema).
  • Patients undergoing colonoscopy for evaluation of symptoms such as abdominal pain, rectal bleeding, diarrhea, constipation, etc, or patient with iron deficiency anemia suspected to be due to ongoing bleeding inside the colon
  • Patients with family history of colon cancer in 1st degree relative below the age of 60
