Narrow band imaging in diagnosis of colorectal polypoid lesions
摘要
Abstract
[ Objective] To evaluate the efficacy of narrow band imaging (NBI) in diagnosis of colorectal polypoid lesions. [ Methods ] 46 patients with colorectal polypoid lesions detected by colonoscopy were enrolled in the study from June 2010 to March 2011. They were observed with conventional colonoscopy, NBI and chromoendoscopy. These lesions were classified by pit pattern (pit) and capillary pattern (CP), which was assessed by reference to histopathology. [ Results ] Fifty four colorectal polypoid lesions were found in 46 patients. For the observation of visualization of silhouette, pit and CP, NBI was better than ordinary endoscope (P <0.01). There was significant difference between NBI and chromoendoscopy in visualization of silhouette and CP (P <0.01). However, no significant difference was detected between 2 methods in pit (P >0.05). The diagnostic accuracy rate, sensitivity and specificity of pit in NBI were 90.7%, 90.9%, 90.0%, respectively. The diagnostic accuracy rate, sensitivity and specificity of CP were 92.6%, 95.3%, 81.8%, respectively. [Conclusions] NBI can show the changes of silhouette of colorectal polypoid lesions, pit and CP clearly and distinguish neoplasm from non-neoplasm coloreclal polypoid lesions, it was very ease to operate.关键词
