要旨 大腸拡大内視鏡診断(pit pattern診断)は,病変の質的診断(腫瘍・非腫瘍性の鑑別)において非常に有用である.大腸206病変を対象としたprospective studyの結果から,質的診断における正診率は,通常観察・色素観察・拡大内視鏡観察それぞれにおいて84.0%・89.3%・95.6%であり,通常観察に拡大観察を加えることで,5~10%の質的診断能の上乗せ効果が見込まれる.また,retrospectiveな解析から,拡大内視鏡の導入により,非腫瘍性病変に対する内視鏡摘除件数は約1/4に抑えられる可能性があり,医療経済効果も十分に期待できる.
Differential diagnosis of malignant and benign colorectal lesions, using colonoscopy is of cardinal importance. Magnifying colonoscopy permits observation of the fine pit pattern, which may result in more accurate diagnosis regarding colorectal lesions at an earlier stage. We have conducted a prospective study to examine whether magnification and/or indigo carmine dye spraying is more reliable than the conventional view for such differential diagnosis. The overall diagnostic accuracy of magnification in addition to chromoendoscopy using indigo carmine was 95.6%, which is 10% and 5% more reliable than conventional endoscopy and chromoendoscopy, respectively. Additionally, that method was significantly superior to conventional endoscopy and chromoendoscopy (p<0.0001 and p=0.0152). Therefore, based on the results, we are able to conclude that the combination of magnifying colonoscopy and chromoendoscopy is the most reliable method for separating non-neoplastic at the present time from neoplastic lesions of the colon and rectum.
