目的探讨内镜窄带成像技术(NBI)和普通肠镜在大肠新生性病变诊断中的应用价值。方法对32例患者进行了NBI检查。内镜插至回盲部,发现病变后先普通肠镜下观察病变的腺管开口和毛细血管形态;后切换至NBI,再观察病变的腺管开口和毛细血管形态;并对比观察病变和周围正常黏膜。结果NBI下可更清晰地观察结、直肠黏膜毛细血管网;对于病变腺管开口的观察,NBI组清晰和非常清晰率达82.7%,明显优于普通肠镜组的18.4%,差异有统计学意义(P<0.05);对比观察结、直肠病变和周围正常黏膜,NBI组清晰可见和非常清晰可见百分率达93.5%,明显优于普通肠镜组的71.8%,差异有统计学意义(P<0.05)。结论NBI技术对大肠新生性病变的观察明显优于普通肠镜,且操作简单易行。
Objective To investigate the value of endoscopic narrow band imaging (NBI) and general colonoscopy in the diagnosis of colorectal neoplasia. Methods 32 patients underwent NBI examination. Endoscopy inserted into the ileocecal Department, found lesions after the first ordinary colonoscopy observed lesions of the duct opening and capillary morphology; after switching to NBI, and then observe the lesions of the duct opening and capillary morphology; and compared the lesions and the surrounding Normal mucosa. Results Under NBI, the junction and rectal mucosal capillary network were observed more clearly. For the observation of pathological duct opening, the clear and very clear rate was 82.7% in NBI group, which was significantly better than that in common colonoscopy group (18.4%) (P <0.05). Compared with the observation group, the percentage of visible and clearly visible NBI group in rectal lesions and surrounding normal mucosa was 93.5%, which was significantly better than 71.8% in ordinary colonoscopy group (P < 0.05). Conclusion The observation of NBI on colorectal neoplasm is obviously superior to ordinary colonoscopy, and the operation is simple and easy.
