生検，内視鏡的摘除および外科切除検体の取り扱い上の留意点―早期大腸癌を中心に

Essentials for a Better Handling of Biopsies and Resected Specimens of the Large Intestine

要旨　検体の取り扱いには，検体の伸展に始まり固定，写真撮影，切り出し，そして組織切片が包埋・薄切・染色されるまでの各段階が包含されている．不適切な取り扱いは組織学的検索のみならず，その後の治療方針決定にも支障を来す．それゆえに検体の取り扱いには正確さ，きめ細かさが要求され，十分な経験と知識をもった医師の指導下で速やかに行われる必要がある．加えて組織標本を作製する技師と連携を緊密にすることも欠かせない．

　The primary aim of examining biopsies and resected specimens is to supply clinicians with essential diagnostic and prognostic information enabling the best clinical management of the individual patient. The handling of specimens includes formalin fixation, taking gross photographs, cutting, paraffin embedding, sectioning, and staining routinely with hematoxylin and eosin. The best clinical pathology service can only be obtained when there is close cooperation and understanding between the pathologists and the laboratory staff on the one hand and clinicians and co-medical staff on the other.
