 We entered a new era of endoscopic diagnosis with the appearance of Magnifying colonoscopy in 1993. For the past 20 years it has been used for comparative research on stereomicroscope observation and the pathology of fixed samples. Recent development has enabled us to easily observe the surface microstructures and crypt orifices of any lesions in the colon or rectum. It has make it possible for us to distinguish accurately pathological features such as neoplasm or non-neoplasm, adenoma or carcinoma, degree of invasion etc. At present, magnifying colonoscopy has reached stage that can be called “virtual biopsy” and it has remarkable value for clinical use etc.

 However, the present stage of the technology is not completely free of difficulties. For instance, the individual variation of criteria, the influence of differential level and dysplatic grade of cancer, the meaning in pit pattern classification use . After sufficient solution of these difficulties has been gained, it can be expected that diagnosis based on magnifying colonoscopy will become used in daily clinical practice.
