Clinical Trial: Comparison of Narrow Band Imaging With or Without Magnifying Colonoscopy
Study Status: Completed
Recruit Status: Completed
Study Type: Interventional
Official Title: A Prospective Clinical Study to Evaluate Narrow Band Imaging and Magnifying Colonoscopy for the Histologic Prediction of Colorectal Polyps
Brief Summary: The aim of this study is to evaluate the usefulness of magnifying colonoscopy with narrow band imaging.
Detailed Summary: The accuracy of histologic prediction for the colorectal polyps with the use of narrow band imaging is evaluated between the test group with magnifying colonoscopy and the control group without magnifying colonoscopy.
Sponsor: Seoul National University Hospital
Current Primary Outcome: Accuracy of colorectal polyp histologic prediction with NBI colonoscopy plus magnification [ Time Frame: After 1 week ]
Original Primary Outcome: Same as current
Current Secondary Outcome:
- Sensitivity of the endoscopic histologic prediction with NBI plus magnification [ Time Frame: 1 Week ]Endoscopically predicted histologic diagnosis compared with confirmed pathologic diagnosis are evaluated in terms of sensitivity.
- Specificity of the endoscopic histologic prediction with NBI plus magnification [ Time Frame: 1 Week ]Endoscopically predicted histologic diagnosis compared with confirmed pathologic diagnosis are evaluated in terms of specificity.
- Positive predictive value of the endoscopic histologic prediction with NBI plus magnification [ Time Frame: 1 Week ]Endoscopically predicted histologic diagnosis compared with confirmed pathologic diagnosis are evaluated in terms of positive predictive value.
- Negative predictive value of the endoscopic histologic prediction with NBI plus magnification [ Time Frame: 1 Week ]Endoscopically predicted histologic diagnosis compared with confirmed pathologic diagnosis are evaluated in terms of negative predictive value.
Original Secondary Outcome: Sensitivity and Specificity of the endoscopic histologic prediction with NBI plus magnification [ Time Frame: 1 Week ]
