Brief Summary
Combined with magnifying endoscopy,narrow-band imaging (NBI) contrasts microvascular architecture on lesion surface.The histology of early colorectal lesions could be predicted under NBI view.However,its capability for estimating invasion depth remains to be verified.The study is based on the hypothesis:NBI can predict histology and invasion depth,combined with the verification of microvessel count and MMP-7 expression.

Outcome Measures
Primary Outcomes (1)
NBI prediction for lesion histology and invasion
We will receive the histologic findings in two weeks after lesion treatment.Then we can compare NBI prediction with the final histologic type.
in two weeks after lesion treatment
Secondary Outcomes (1)
immunohistochemical outcome of microvessel count and MMP-7
in three days after immunohistochemistry
Eligibility Criteria
patients with early colorectal lesions
You may qualify if:
- patients of early colorectal lesions with capillary pattern(CP) type II\&III,initially detected by white-light view and then examined by NBI with magnifying endoscopy.
You may not qualify if:
- lesions with CP type I;
- CP type III lesions with an obvious appearance of advanced cancer;
- lesions that had underwent biopsy;
- patients with inflammatory bowel disease(IBD) or familial adenomatous polyposis(FAP)
- patients with previous colorectal surgery;
- having conditions associated with cardiac,hepatic,renal,and coagulopathy diseases.
