Brief Title: Comparison of Diagnostic Accuracy for Predicting Histology of Colorectal Lesions
Official Title: Comparison of Diagnostic Accuracy for Predicting Histology of Colorectal Lesions Using Magnifying Colonoscopy With Narrow Band Imaging, Indigo Carmine, and Acetic Acid Staining
Study ID: NCT01521091
Brief Summary: Chromoendoscopy (indigo carmine or acetic acid) and Narrow Band Imaging (NBI) could make accurate evaluation in predicting of invasive depth of colorectal neoplasia. NBI could be the first choice.
Detailed Description: To compare the diagnostic accuracy of chromoendoscopy indigo carmine or acetic acid and NBI for differentiating neoplastic from non-neoplastic colorectal lesions, differentiating adenomas from carcinomas, and differentiating early carcinomas from invasive ones. Included colorectal lesions consecutively distribute in a 1:1 ratio to 2 groups.
