Official title
A Multicenter, Prospective, Randomized Controlled Trial for the Detection of Colon Polyps and Predicting Histology
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
In this study the investigators hypothesize that High Definition White Light colonoscopy and narrow band imaging (NBI) will detect a higher number of adenomas compared to standard definition white light colonoscopy. NBI will have a higher accuracy in predicting polyp histology compared to high definition colonoscopy and standard colonoscopy. Specific Aim 1 - To compare the prevalence of adenomas detected by standard colonoscopy, high-definition white light colonoscopy and NBI. Specific Aim 2 - To compare the number of adenoma detected per subject by standard colonoscopy, high-definition white light colonoscopy and NBI. Specific Aim 3 - To compare the accuracy of predicting polyp histology between standard colonoscopy, high-definition white light colonoscopy and NBI by evaluating the surface mucosal and vascular patterns during the procedure. Specific Aim 4 - To determine the inter-observer agreement between investigators for the recognition of various polyp patterns
