title: Intraoperative localization of small bowel bleeding sites with combined use of angiographic methods and methylene blue injection.
abstract: Superselective catheter placement with angiographic techniques and methylene blue injection at laparotomy through a prepositioned angiographic catheter have helped to localize small bowel bleeding lesions. The technique has been applied successfully in two patients with arteriovenous malformations and one patient with bleeding mucosal ulcerations of the small bowel.
