Accounts for 2% - 5% of all acute GI bleeding, but it can be the cause of recurrent &often potentially life-threatening hemorrhage.
Has a predilection for the proximal stomach.
It is increasingly apparent that these lesions, although usually gastric, may develop throughout the GI tract (esophagus 2%, jejunum 2%, colon 10%).
A variety of endoscopic modalities, including monopolar / bipolar electrocoagulation, heat probe coagulation, injection sclerotherapy, hemoclip placement, endoscopic band ligation, laser photocoagulation, have been used, either alone or in combination, with a success rates of 90%-95% &a rate of recurrent bleeding of 5%-10%.
Because of the small size of the lesion, the normal surrounding mucosa& the intermittent nature of the bleeding, endoscopic diagnosis is challenging & may require multiple and combined procedures.
