Small-bowel endoscopy.

During the last year, promising results with the first clinical applications of capsule endoscopy have been reported; this is a new, revolutionary diagnostic method for endoscopic study of the small bowel. The method has chiefly been used in patients with obscure gastrointestinal bleeding, and in some cases has allowed additional diagnoses to be made in comparison with push enteroscopy, with a positive influence on patient management. New therapeutic possibilities have also been developed in push enteroscopy, emphasizing the role of this technique as an essential component of gastrointestinal endoscopy. Important innovations in enteroscopy technique have been described, aimed at increasing the depth of examination, and these will probably make it possible to extend endoscopic treatments to include the entire small bowel. Finally, numerous articles are still being published concerning intraoperative enteroscopy. It is to be hoped that, in future, the use of this invasive procedure will be based on data acquired by capsule endoscopy.
