[Dieulafoy's simple stomach ulcer: apropos of 5 cases]

Dieulafoy's ulcer is a probably congenital arterial malformation which may produce severe upper gastrointestinal haemorrhage. It represents about 1% of all cases of acute upper gastrointestinal haemorrhage (3/249 in our department during 1989). We report 5 cases in whom haemostatic endoscopic treatment was successful and propose therefore that this therapy should be the initial treatment of choice. Surgical intervention should be considered only if endoscopic therapy fails.
