Summary
Brief summary (as posted)
Colonoscopy( examining the colon with a flexible tube and a camera ) is usually done for screening purposes to find any precancerous lesions (polyps) at an early stage. During the colonoscopy the doctor will advance the colonoscope to the end of your colon and start examining the colon for any polyps. "Withdrawal time" is the period of time the doctor spends examining the colon. Doctors usually spend six minutes examining the colon after they reach the end of the colon. Studies have showed that spending more withdrawal time detects more lesions. The proposal to dedicating half of the withdrawal time during colonoscopy in examining the right side will increase the detection of polyps in the right side of the colon. There will be no other changes in the procedural aspect of the colonoscopy.

- label
- non segmental withdrawal
- description
- A standard of care colonoscopy will be done on the patient without extra time on the right side of the colon.
- label
- Segmental withdrawal
- description
- A standard of care colonoscopy will be done on the patient , however the time spent in the right side of the colon will be more than half of the normal colonoscopy procedure (i.e. more than 3 minutes)
- interventionNames
- Other: Segmental withdrawal

- Increase in detection rate of adenomas in the right side of the colon
- timeFrame
- 30 minutes
- description
- To determine if timed segmental withdrawal protocol can increase the adenoma detection rate in the right side of the colon compared to non segmental withdrawal.
