This research study is about determining how well a Technically Improved Colonoscope from
Olympus works in helping the doctor in guiding the scope through the large bowel or colon.
When a doctor performs a colonoscopy he guides or inserts the scope from the rectum to the
appendix where the small bowel ends and the large bowel begins. There are points during this
insertion where there are turns in the colon which can create a loop in the colonoscope.
These loops can stretch the colon and create some discomfort and also require special
maneuvers by the nurse or patient to help reduce or minimize the loop. Thus, reducing the
looping will make it more comfortable for the patient and more efficient for screening for
polyps. The purpose of the study is to examine this colonoscope and compare it to the
traditional adult colonoscope (Olympus CF-H180). The investigators hypothesis is that this
colonoscope will function better with regard to insertion of the scope from the rectum to the
