Role of capsule endoscopy in the management of patients with obscure gastrointestinal bleeding.

The recent emergence of capsule endoscopy has entailed a relevant diagnostic imaging advance for gastrointestinal conditions, especially those involving the small bowel. Gastrointestinal haemorrhage of obscure origin is probably the most widely accepted indication for this new technique, and promising results have been reported from series extant to date. In view of data available on this new modality, and looking forward to having wide, well designed studies fr corroboration, this paper suggests a tentative algorithm for the management of this patient group.
