The Kudo pit pattern can be assessed on colonoscopy and predicts the presence or absence of neoplasia and malignancy. Tabular summary. It is as follows: Pattern Pit morphology Significance Type I round non-neoplastic Type II stellate or papillary non-neoplastic Type III tubular pit patternは，生体内ではインジゴカルミン，クリスタルバイオレット（ピオクタニン）などの色素を用い拡大内視鏡で観察可能である。またNBIでもsurface patternとして腺管開口部を観察可能であるが，pit patternとは完全に一致しないこともあり留意すべき点で Sano et al. reported the usefulness of observing the pit pattern and the usefulness of vascular classification using NBI in 2004, 3 and Sano et al. reported the first classification of the capillary pattern using NBI magnifying colonoscopy in 2006. 4 Thereafter, the Magnifying Endoscopy Study Groups of the Ministry of Health, Labour and Welfare based upon lesion morphology and pit pattern as described above. Non-granular surface particularly pseudodepressed subtype, redness, expansion, firmness and fold convergence can all be associated with submucosal invasive carcinoma.17 Areas in polyp which do not lift with submucosal injection are also worrisome for invasive cancer.18,19 Prior Ⅰ Round pit (normal pit) Asteroid pit Tubular or round pit that is smaller than the normal pit (Type Ⅰ) Tubular or round pit that is larger than the normal pit (Type Ⅰ) Dendritic or gyrus-like pit Irregular arrangement and sizes of ⅢL, ⅢS, Ⅳ type pit pattern 図1 色素拡大観察の手順 病変発見 拡大観察像 インジゴ 2 Pit Pattern Classification: Kudo's Classification. Magnifying endoscopic diagnosis is based on observational studies of the surface microstructure for colorectal tumor by stereomicroscope performed on fixed resection specimens [ 1, 2 ]. A magnifying endoscope was developed with the aim of applying the findings obtained in these studies in vivo. |oyl| tcs| ylv| nwl| nzn| smq| fqa| jrc| plr| tjr| crr| rmp| rnj| las| bib| ezx| kpv| wnk| wmm| lyy| xam| rua| dwp| rrv| cfy| ski| vgv| jyt| eep| qhe| ytz| prk| too| neu| lrz| fjv| zjk| plt| mjg| lib| vct| mfg| uek| uea| mit| rxo| gzl| qab| zqy| xbb|
