【 要旨 】 カプセル内視鏡はバルーン内視鏡とともに小腸疾患の診断・治療に活躍している.病悩期間の長かった小腸疾患患者のなかで,小腸に病変が特定され,治療により病苦から解放された患者も少なくない.その有用性からカプセル内視鏡は保険適応となり,また適応疾患も拡大し小腸疾患の全体像を明らかにしつつある.侵襲の少ないカプセル内視鏡は非ステロイド性抗炎症薬やアスピリン起因性の小腸傷害を明らかにするなど,今まで知られてこなかった小腸疾患の解明に役立っている.カプセル内視鏡自体も技術の進歩に伴い画像は鮮明となり,体外機器との相互通信も可能となってきている.技術の進歩は小腸疾患解明にさらなる飛躍をもたらすであろう.

[ Summary ] Capsule endoscopy and balloon‒assisted endoscopy are useful in the diagnosis and treatment of small intestinal diseases. A large number of patients with small intestinal disease who suffer from prolonged illness actually exhibit complete recovery after treatment. Since capsule endoscopy has proven to be effective in the diagnosis of small intestinal disease, it is available for small intestinal examination through the Japanese National Insurance. Capsule endoscopy, which is a minimally invasive investigation, is also useful for identifying many conditions in the small intestine such as those secondary to treatment with aspirin and othernonsteroidalanti‒inflammatorydrugs (NSAIDs). The technology underlying capsule endoscopy is rapidly advancing, which has resulted in increased clarity of images and development of systems that allow interaction between the capsule and the external hardware. Such advances in capsule endoscopy are expected to have a significant impact in the field of small intestinal disease‒management.
