简要总结

The purpose of this study is to determine whether the new colonoscope that provides both a traditional and a retrograde view (bending 180 degrees to look behind itself) of the colon can detect more polyps than a standard colonoscope that only provides a forward-facing view. The investigators wish to effectively demonstrate the utility of the new colonoscope (Pentax Retroview Colonoscope) as the objective of this study is to determine polyp and adenoma detection rates in human subjects undergoing colonoscopy for polyp surveillance.

研究组 & 干预措施

Short-Turn Radius Colonoscope

Experimental

Colonoscopy performed with Short-Turn Radius Colonoscope. The colonoscope will provide a forward-facing view of the colon during advancement to the cecum (standard of care). The scope will then be withdrawn all the way to the rectum and the colon will be inspected using the forward-facing view (standard of care). The colonoscope will then be re-advanced to the cecum and be withdrawn using the retrograde view.

干预措施: Short-Turn Radius Colonoscope (Device)

Conventional Pediatric Colonoscope

Active Comparator

Colonoscopy will be performed with a conventional pediatric colonoscope. During withdrawal, the colon will be inspected using the forward-facing view (standard of care). The colonoscope will then be re-advanced to the cecum and again withdrawn using the forward-facing view.

干预措施: Conventional Pediatric Colonoscope (Device)
