Why is colonoscopy preparation important?

This question was asked in East Los Angeles, California on 04/06/2012.
Why is there so much preparation that you have to go through before a colonoscopy? I heard that the bowel preparation is worse than the colonoscopy procedure. What does that mean?

The preparation is the most important part. The cleaner the colon, the better the exam.
