Overview
Gastric antral vascular ectasia is an uncommon cause of chronic gastrointestinal bleeding or iron deficiency anemia. The condition is associated with dilated small blood vessels in the antrum, or the last part of the stomach. It is also called watermelon stomach because streaky long red areas that are present in the stomach may resemble the markings on watermelon[1].
Historical Perspective
The condition was first discovered in 1952, and reported in the literature in 1953.[2] Watermelon disease was first diagnosed by Wheeler et al. in 1979, and definitively described in four living patients by Jabbari et al. only in 1984. As of 2011, the etiology and pathogenesis are still not known.[3] However, there are several competing hypotheses as to various etiologies.
Asociated Conditions
GAVE is associated with a number of conditions, including
Differentiating Gastric antral vascular ectasia from other Diseases
GAVE should be differentiated from other causes of intestinal bleeding such as
The differential diagnosis is important because treatments are different.
Diagnosis
Endoscopy
The endoscopic appearance of GAVE is similar to portal hypertensive gastropathy.
Treatment
GAVE is treated with treatment through the endoscope, including argon plasma coagulation and electrocautery. Other medical treatments have been tried and include estrogen and progesterone therapy and anti-fibrinolytic drugs such as tranexamic acid.
