It exists a learning curve in using NBI with magnification to differentiating colorectal lesions.
|Condition or disease|
It is very useful to use narrow-band imaging and Sano CP analysis in the differential diagnosis of colorectal lesions. The endoscopists who had never used NBI or no knowledge of NBI can have effective and stable diagnostic accuracy after using NBI with magnification to diagnose 15 target and non-target lesions respectively.
|Study Type :||Observational|
|Actual Enrollment :||326 participants|
|Official Title:||The Learning Curve of NBI With Magnification in the Diagnosis of Colorectal Lesions|
|Study Start Date :||May 2010|
|Primary Completion Date :||April 2011|
|Study Completion Date :||April 2011|
Primary Outcome Measures :
- Accuracy, Sensitivity, and Specificity for Differentiating Neoplastic and Non-neoplastic Lesions [ Time Frame: For this training, patients were consecutively enrolled until a total of 45 target and non-target lesions were obtained. ]
Biospecimen Retention: Samples Without DNA
if the lesion is neoplastic or sm deeper cancer, we just take biopsy.If the lesion is adenomatous or sm1-2 cancer,we do polypectomy, EMR or ESD to get the specimen.
