| Abstract | 「要旨」下部消化管出血疑診例に対して, Technetium-99m標識赤血球を用いた腹部シンチグラムを施行した68例を分析した. 発症後24時間以内または入院後24時間以内に検査を施行した36例中27例(75%)に陽性所見を得た. 検査施行が入院後または発症後24時間以降となった32例では, 18例(56%)に陽性所見を得た. 検査陽性例45例中21例(47%)は, アイソトープ注射後1時間以降に陽性となっており, 間欠的に出血するような症例にも有用であった. 検査は全例において副作用等なく安全に施行された. 局在診断的目安を得たことによって引き続いて血管造影, 内視鏡等の侵襲的な検査をより選択的に行い, 早期に確定診断をつけることが可能となった. 本検査法は非侵襲的, 簡便かつ感度も高く, 下部消化管出血疑診例において第一に選択すべき検査法と考えられた. |

| Abstract | [Summary] A three years' experience at Chigasaki Tokushukai Medical Center with Techentium-99m labeled red blood cell scintiscans (Tc-99m-RBC Scan) performed on 68 cases of suspected lower gastrointestinal (LGI) bleeding was reviewed in retrospect. Of the 36 cases performed within 24 hours from the clinical detection of active LGI hemorrhage on emergency basis, 27 cases were positive (75% positivity). Of the total 45 positive cases, 21 (47%) became positive one or more hours post injection, confirming the intermittent nature of the LGI hemorrhage. All studies were completed without untoward effects and confirmed the noninvasive nature of the study, as compared to the other invasive modalities such as endoscopy and angiography. Detection and localization of the site of LGI bleeding directed the precise modality to be chosen subsequently and greatly facilitated in performing the invasive procedure with selectivity further improving its sensitivity. Tc-99m-RBC scan is a completely noninvasive, simple and sensitive procedure, which may be used initially in routine to detect and localize LGI bleeding. |
