|Condition or disease|
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.
|Study Type :||Observational|
|Actual Enrollment :||565 participants|
|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 Start Date :||January 2009|
|Actual Primary Completion Date :||December 2010|
|Actual Study Completion Date :||December 2010|
All the lesions will be removed endoscopically or surgically and examine histologically by an independent gastrointestinal pathologist.
Histological diagnosis is determined according to the World Health Organization (WHO) criteria. Pedunculated lesions are categorized according to Haggitt's classification.
