title: Dieulafoy's lesion: an obscure cause of GI bleeding.
abstract: Dieulafoy's lesion is an uncommon cause of major gastrointestinal bleeding and may be difficult to recognise. It consists of an arteriole that protrudes through a tiny mucosal defect, usually within 6 cm of the gastroesophageal junction on the lesser curve of the stomach. Similar lesions have also been described in the distal oesophagus, small intestine, colon, and rectum. Awareness of the condition and experience in endoscopy are the mainstay of diagnosis. Therapeutic endoscopy is the first line of treatment. It is safe, effective and has very good long term results.
