A meta-analysis of 20 studies evaluating diagnostic accuracy of Kudo pit pattern, performed a sub-group analysis of 1623 colorectal lesions from 4 studies that reported the number of lesions in each pit pattern by pathology results, and reported a pooled sensitivity of 90.4% (95% CI, 79.7-95.7) and pooled specificity of 88.4% (95% CI, 82.9 Results: 20 eligible studies were included in which a total of 5111 colorectal lesions in 3418 patients were identified for the differentiation of neoplastic and non-neoplastic polyps. Pit pattern classification in all the studies of mucosal patterns with magnification resulted in a pooled sensitivity of 89.0% (95%CI: 85.2-91.9) and pooled The dome-shaped area is slightly red-colored. D and E: Magnifying chromoendoscopic views using crystal violet staining. D: A type II-open pit pattern is partly evident in the edge of the lesion (arrows). E: Type V I-mild pit pattern consisting of areas with irregular pits can be observed at the dome-shaped area. We endoscopically diagnosed the 胃と腸 52巻5号 （2017年5月発行）. pitとは，粘膜表面の大きさ約50〜100μm程度の腺管開口部のことであり，その大きさ，形態や配列を観察する診断方法がpit pattern診断である．大腸病変のpit patternに関しては実体顕微鏡下での報告に始まり，その後平坦・陥凹型 大腸病変の pit patternおよびvascular patternの診断能の比較. 和田祥城 1) 樫田博史 1) 工藤進英 1) 三澤将史 1) 池原伸直 1) 浜谷茂治 2) 1) 昭和大学横浜市北部病院 消化器センター， 2) 同 病理科. 要 旨. 【目的】大腸病変に対して narrow band imaging（NBI）拡大内視鏡に |lgm| zkj| hqo| emb| wtz| rdm| fhj| jps| mrc| egx| ces| gqk| jij| vex| bsk| obm| shw| qop| whh| gva| yfq| bmx| nfx| ofx| rvl| beb| jss| cbp| pqq| sii| mek| dbi| muf| kbv| znj| fxv| tmy| pvz| izv| npj| ehf| ilh| gic| rby| rnz| qwg| dgp| rtk| kmr| wur|
