Abstract	目的 : ERCP (endoscopic retrograde cholangiopancreatography) 施行時に採取された細胞診標本が不良になる原因としての造影剤の影響とブラシ洗浄標本の有効性を検討した.方法 : 胆嚢23 例を用い, 胆嚢粘膜ブラシ擦過直接塗抹標本, 造影剤原液および希釈液浸漬後ブラシ擦過直接塗抹標本, 生理食塩水洗浄標本, 造影剤原液と造影剤希釈液の各溶液でブラシを洗浄した洗浄液標本を作製し, 細胞形態を比較した.成績 : 造影剤原液および 2 倍, 8 倍希釈造影剤浸漬後ブラシ擦過直接塗抹標本と造影剤原液および 2 倍, 8 倍希釈造影剤を用いた洗浄標本では, 核や細胞質の濃縮, 濃染などアーチファクトが強く細胞構造が不明瞭となり, 診断には不適正な標本となった. 16 倍, 32 倍希釈造影剤浸漬後ブラシ擦過直接塗抹標本と造影剤 32 倍希釈液洗浄液標本では生食洗浄液標本と同様の所見であった.結論 : 造影剤は固定作用を妨害していることが示唆された. ERCP 施行時の細胞診標本は造影剤原液の付着したブラシ直接塗抹標本より, 造影剤の希釈されるブラシ洗浄液標本が有効であると考えられた.
