Comparison of Diagnostic Accuracy for Predicting Histology of Colorectal Lesions Using Magnifying Colonoscopy With Narrow Band Imaging, Indigo Carmine, and Acetic Acid Staining
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.
