Gastric antral vascular ectasia(GAVE) has been recognized as one of the important causes of occult and obscure gastrointestinal bleeding.The diagnosis is typically made based on the characteristic endoscopic features,including longitudinal row of flat,reddish stripes radiating from the pylorus into the antrum that resemble the stripes on a watermelon.These appearances,however,can easily be misinterpreted as moderate to severe gastritis.Although it is believed that capsule endoscopy(CE) is not helpful for the study of the stomach with its large lumen,GAVE can be more likely to be detected at CE rather than conventional endoscopy.CE can be regarded as "physiologic" endoscopy,without the need for gastric inflation and subsequent compression of the vasculature.The blood flow of the ecstatic vessels may be diminished in an inflated stomach.Therefore,GAVE may be prominent in CE.We herein describe a case of active bleeding from GAVE detected by CE and would like to emphasize a possibility that CE can improve diagnostic yields for GAVE.
