Inspection of the Colon Using a Retrograde Viewing Device for Detection of Colorectal Polyps

During standard colonoscopy a substantial number of colorectal polyps may be missed. Previous studies have found a 12-28% of miss rate for all polyps, a 31% for hyperplastic polyps and 6-27% for adenomas. In this study it is tested whether a retro viewing endoscope can detect more colorectal polyps in comparisson to standard forward viewing endoscopy. Further, ppolyps detected, mean adenomas per Patient and withdrawal time are recorded.
