BACKGROUND Small bowel sources of obscure gastrointestinal bleeding present both a diagnostic and therapeutic challenge. Due to the normal external appearance of the vast majority of small bowel lesions that cause obscure gastrointestinal bleeding, multiple methods of intraoperative localization have been reported. When an arteriographic abnormality is found, the use of vital dye enteric mapping is one of the most effective localization techniques. METHODS We present a new technique combining superselective mesenteric angiography with methylene blue enteric mapping and small bowel resection performed during the same operative procedure. This technique was successfully applied in a patient with a jejunal arteriovenous malformation. Included is a review of methods of intraoperative localization with a focus on vital dye staining-guided enterectomy.

D008751	Methylene Blue	A compound consisting of dark green crystals or crystalline powder, having a bronze-like luster. Solutions in water or alcohol have a deep blue color. Methylene blue is used as a bacteriologic stain and as an indicator. It inhibits GUANYLATE CYCLASE, and has been used to treat cyanide poisoning and to lower levels of METHEMOGLOBIN.

D001165	Arteriovenous Malformations	Abnormal formation of blood vessels that shunt arterial blood directly into veins without passing through the CAPILLARIES. They usually are crooked, dilated, and with thick vessel walls. A common type is the congenital arteriovenous fistula. The lack of blood flow and oxygen in the capillaries can lead to tissue damage in the affected areas.	Arteriovenous Malformation,Malformation, Arteriovenous,Malformations, Arteriovenous
