Not Applicable

• Conditions: Colonoscopy

• Registration Number: NCT00365534
• Lead Sponsor: Chinese University of Hong Kong

Brief Summary

The aim of this study is to compare the mechanism of loop formation and acceptance of CAC and regular colonoscopy by MEI.

Detailed Description

Colonoscopy is widely used for the investigation of lower gastrointestinal tract disease.However,colonoscopy remains a technically difficult procedure. As the colon is a mobile organ, looping may occur when the colonoscope passes through.Hence,reducing looping during procedure is very improtant to achieve succes as well as patient acceptance.Recently,some studies shown that cap-assisted colonoscopy(CAC)allow better visualisation of the colonic folds, thus increase success rate.However, previous studies shown that magnetic endoscope imaging (MEI)is useful as an adjunct to assist endoscopist in performing the procedure and as a modality to look for the mechanism of looping. Because of such concern,our study is to compare the mechanism of looping formation and acceptance of CAC and regular colonoscopy by MEI.
