  Purpose

Colorectal cancer (CRC) is the third most common cancer and second leading cause of cancer deaths in western countries. Colonoscopy is a preferred colorectal screening modality since it has both diagnostic and therapeutic capability. Detection and removal of polyps at colonoscopy decreases the incidence and mortality from colorectal cancer.

Typical practice is to insert the colonoscope rapidly until it reaches the cecum (a pouch-like portion of the intestines, where the large bowel and the small bowel meet). The physician then withdraws the colonoscope slowly and looks for any polyps or abnormalities within the large bowel. The purpose of this study is to compare this standard practice to the approach whereby the physician examines the bowel as the scope is initially inserted AND as the colonoscope is withdrawn from patients' colons.

Primary Outcome Measures:
  • Adenoma detection rates for each method [ Time Frame: within the first 30 days after colonoscopy ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Comparison of procedure times for each method [ Time Frame: 1 year ] [ Designated as safety issue: No ]
  • Percentage of patients with at least one adenoma detected by each method [ Time Frame: 1 year ] [ Designated as safety issue: No ]
  • Comparison of percentage of adenomas classified as high risk for each method [ Time Frame: 1 year ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Standard Inspection Colonoscopy
The colonoscope will be inserted rapidly to reach the cecum. Inspection of the large bowel will occur during the withdrawal of the colonoscope.
Procedure: Standard Inspection Colonoscopy
The large bowel will be inspected for polyps during the withdrawal of the colonoscope to the cecum, and during the withdrawal of the scope from the large bowel.
Active Comparator: Dual Inspection Colonoscopy
The large bowel will be inspected for polyps during the insertion of the colonoscope to the cecum, and during the withdrawal of the scope from the large bowel.
Procedure: Dual Inspection Colonoscopy
The large bowel will be inspected for polyps during the insertion of the colonoscope to the cecum, and during the withdrawal of the scope from the large bowel.
