title: [Dieulafoy's lesion: rare cause of massive upper gastrointestinal bleeding].
abstract: Dieulafoy's lesion is an unusual and potentially life-threatening cause of massive, recurrent gastrointestinal bleeding. Its reported incidence as a source of upper gastrointestinal bleeding ranges from 0.3-6.7%. Dieulafoy's lesion is most commonly located in the proximal stomach (75% of cases). Lesion typically occur within 6 to 10 cm of the esophagogastric junction, generally along the lesser curvature of the stomach. Similar lesions have been identified in the esophagus, duodenal bulb, jejunum, ileum, colorectum, anal canal, even in bronchus. Detection and identification of the Dieulafoy's lesion as the source of bleeding can often be difficult, especially because most present with massive bleeding. Because of intermittent nature of bleeding, initial endoscopy is diagnostic in 60% of the cases, so repeated endoscopies are often necessary. If the lesion can be endoscopically documented, attempts should be made to achieve hemostasis using one or a combination of several endoscopic modalities. Success has been reported with multipolar electrocoagulation, heater probe, noncontact laser photocoagulation, injection sclerotherapy, endoscopic hemoclipping and band ligation. Surgery is reserved for lesions that cannot be controlled by endoscopic techniques. When localized, a wide wedge resection of entire area traversed by the large submucosal artery is recomended because rebleeding has been described after simple coagulation and ligation.
