A Dangerous Gastric Bleeding Cause: Dieulafoy's Lesion

Bleeding is a complication of gastrointestinal vascular malformation and may be an emergency. Dieulafoy's lesion is rare but the aberrant submucosal artery may cause gastrointestinal bleeding. It is most commonly located in the proximal part of the stomach. Endoscopy is used for diagnosis and treatment. Mass lesions, diffuse lesions and severe bleeding may require surgery. Wedge resection or lesion suturing may be selected for gastrointestinal haemorrhage.
