Dieulafoy's anomaly is a vascular malformation of the upper stomach, w
hich typically causes massive and recurrent haemorrhage. Emergency end
oscopy is the most effective method of diagnosing the disease. Until r
ecently, the therapy of choice was surgical resection. Five patients w
ith spontaneously stopped bleeding from Dieulafoy's ulceration were in
vestigated. Transendoscopic Doppler ultrasound was used to identify ar
terial blood flow from the lesions. Local injection treatment was perf
ormed. Successful therapy resulted in the disappearance of arterial pu
lsations and no rebleeding occurred. The endoscopic Doppler is of diag
nostic value in the evaluation of Dieulafoy's ulcer and enables contro
l of endoscopic sclerotherapy.
