Abstract:
Objective Taken examination of patients with colon polyps by using narrow-band imaging (NBI) com-bined with magnified endoscope, to compare the difference in the opening of the gland morphology and pathological type. Methods 110 patients of colon polyps with 147 pathological histology biopsy samples collected. Using NBI combined with magnified endoscope techniques observe pit patterns and capillary patterns identify adenomatous polyps, and compared with the results of pathological histology, then analyze the adenomatous polyp diagnosis coin-cidence rate, sensitivity and specificity. Results The pit patterns of adenomatous polyps were mostly type Ⅲ, Ⅳ andⅤ. The diagnostic coincidence rate, sensitivity and specificity was 91.16%, 88.37%, 95.08%of adenomatous polyps. It was higher than ordinary colonoscopy (80.27%, 79.07%, 81.97%), and the diagnosis accuracy of intraepithelial neoplasia and early carcinoma of NBI combined with magnified endoscope was obviously higher than that by ordi-nary endoscopy examination, the differences were statistically significant. Conclusions NBI combined with magnified endoscope was superior in observing the opening of pit patterns and capillary patterns, which was helpful to diagno-sis of tumor lesions of colon polyps.
