窄带成像结合放大内镜对110例结肠息肉的观察分析

Analysis of NBI combined with magnified endoscopy in examination of patients with colon polyps (110 cases)

摘要:

目的 运用窄带成像（NBI）结合放大内镜对结肠息肉进行观察分析，比较其在腺管开口形态及病理学类型的差异。方法 肠息肉患者110例，共留取147个病理组织学活检样本，利用NBI结合放大内镜技术观察结肠息肉腺管开口类型、微血管形态与肿瘤性息肉的关系，并与病理组织学比较，分析肿瘤性息肉的诊断符合率、敏感性及特异性。结果 肿瘤性息肉的腺管分型多为Ⅲ、Ⅳ、Ⅴ型。对肿瘤性息肉的诊断符合率、敏感性及特异性（91.16%、88.37%、95.08%）均高于普通肠镜（80.27%、79.07%、81.97%），且NBI放大内镜诊断上皮内瘤变及早癌的准确率也明显高于普通内镜，差异均有统计学意义。结论 NBI结合放大内镜能更清楚地观察到息肉表面的腺管开口及表面微血管形态，有利于结肠息肉样肿瘤性病变的诊断。

Abstract:

Objective Taken examination of patients with colon polyps by using narrow-band imaging (NBI) combined 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 coincidence rate, sensitivity and specificity. Results The pit patterns of adenomatous polyps were mostly type Ⅲ, Ⅳ and Ⅴ. 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 ordinary 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 diagnosis of tumor lesions of colon polyps.
