Brief summary

Hypothesis-- Nurse observation in addition to the colonoscopist while withdrawing the colonoscope from the cecum leads to a greater adenoma detection rate. Methods- Patients presenting for screening colonoscopy are randomized to nurse observation or usual practice. Risk factors for adenoma development and the adenoma detection rate in each group will be evaluated.
