Management of foreign bodies of the gastrointestinal tract is not standardized among the various specialties and subspecialties of physicians who care for these patients. This article gives a true emergency department approach to the patient with an ingested or inserted gastrointestinal foreign body. Evaluation and management of the foreign body by location are presented. Controversial issues such as Foley catheter removal of esophageal foreign bodies, management of sharp objects in the stomach, and management of body packers and body stuffers are discussed. Examples of foreign bodies encountered by the typical emergency physician are demonstrated. PMID: 8681881 [PubMed - indexed for MEDLINE] 要旨:鋭的異物(針,ピン,カミソリ,爪楊枝,魚骨,chicken bone)が胃を通過した後小腸と大腸で腸管穿孔を防ぐ2つの現象が起こる.鋭的な部分が粘膜に突き刺さると,その腸管は部分的に蠕動運動が止まる.食物残渣が引っかかり鈍的な部分が肛門側へ向いて抜けると蠕動運動が再開する.大腸では異物に便が全周性に付着し,異物は便塊の中央に位置する傾向がある.その2つの防御機構のおかげで鋭的異物でも手術を要する穿孔を起こす頻度は25%(15〜35%)程度である.その機構を障害する下剤は鋭的異物例には禁忌である.
