- Primary Outcome Measures
Name Time Method <p>Poly detection ratio: the percentage of colonoscopies with at least one<br /><br>colonic polyp as compared to the total number of colonoscopies.<br /><br>(Ref: colonoscopic Withdrawal Times and Adenoma Detection during Screening<br /><br>Colonoscopy.

- Secondary Outcome Measures
Name Time Method <p>1 The total number of polyps seen during colonoscopy, divided by the total<br /><br>number of colonoscopies<br /><br>2. The total number of polyps removed during colonoscopy, divided by the total<br /><br>number of colonoscopies<br /><br>3. The total number of polyps retrieved for pathological investigation, diverd<br /><br>by the total number of colonoscopie<br /><br><br /><br>These parameters wille be expressed in a percentage and will be determined for<br /><br>polyps with a stalk and for flat polyps, acoording to their resepctive sizes (<br /><br>(< 5 mm, 5-10 mm, > 10 mm).<br /><br>(Ref: Colonoscopic Withdrawal Times and Adenoma Detection during Screening<br /><br>Colonoscopy.
