Abstract:
Objective To observe the meshed capillary pattern(CP)on the surface of colorectal lesions by narrow-band imaging system with magnifying endoscopy(NBI-ME),and to distinguish neoplasm from non-neoplasm by the change of capillary patterns.Methods A total of 144 colorectal lesions in 102 patients detected by conventional colonoscopy were evaluated by NBI-ME to observe the CP on surface,and by staining magnifying colonoscopy to observe the pit pattern.Results All lesions were resected endoscopically (129/144)or by surgery(15/144),and the pathological evaluation diagnosed 30 cases of non-neoplasm (including 20 cases of hyperproliferative polyps and 10 of inflammatory polyps)and 1 14 cases of neoplasm (including 95 cases of adenoma and 19 cases of adenocarcinoma).The diagnostic accuracy rate,sensitivity and specificity of conventional colonoscopy were 75.7%,85.1%and 40.O%,respectively,which were significantly lower than those of NBI-ME and staining magnifying colonoscopy(P＜0.005),while there was no significant difference between NBI-ME and staining magnifying colonoscopy.The CP of type Ⅰ,Ⅱ,Ⅳ and Ⅵa were totally correspondent with pit pattern of type Ⅰ,Ⅱ,Ⅳ and ⅤI. Conclusion NBI-ME findings of colorectal lesions correlated with those of staining magnifying colonoscopy.These two techniques are both helpful in differentiating colorectal neoplasms from non-neoplasms.
