FICE不同波长组合加放大内镜观察大肠隆起性病变微细结构的应用研究

The Clinical Research of Different Combination of FICE Wave Length and Magnifying Endoscope Observes the Fine Structure of the Colorectal Eminence Lesions

目的:探讨应用FICE波长最佳组合+放大内镜观察大肠隆起性病变微细结构,与病变病理学诊断结果相对照,对大肠隆起性病变作出正确及时的诊断并加以治疗。方法:用放大变焦结肠镜常规检查,记录病灶部位,形态。用FICE的10种红绿蓝(RGB)不同波长组合,观察粘膜表面的微细腺管形态及微血管形态,记录最佳波长组合,然后使用放大40-200倍放大病灶。结果:通过应用FICE不同波长最佳组合+放大内镜观察结肠隆起性病变的微细结构,与病理组织学诊断符合率在90%以上。结论:根据FICE不同波长最佳组合+放大内镜观察可即时鉴别结肠粘膜的肿瘤性及非肿瘤性病变,指导相应的镜下或手术治疗,提高诊治早期大肠癌的敏感性和准确率。

Objective： Use the comparison between the optimum combination of FICE wave length adding magnifying endoscope and the result of pathology ,in order to diagnose correctly and treat the colorec-tal eminence lesions in time .Method：By magnifying colonoscopy routine examination , record location , mor-phology, by the different combination of FICE wave length （RGB）,Observe micro gland mucosal surfaces of the tube shape and microvascular morphology ,record the optimum wavelength combination ,magnify he lesions 40-200 times.Results： The use of the optimum combination of FICE wavelength adding magnifying endo-scope answers for rate of above 90%of histopathological diagnosis .Conclusion：Using the optimum combina-tion of FICE wavelength adding magnifying endoscope can identify the colonic mucosal neoplastic and non ne -oplastic lesions instantly ,advise the treatment of the corresponding microscopic or operation ,improve the sen-sitivity of diagnosis and treatment of early colorectal cancer and accuracy .
