Review article: current therapeutic options for gastric antral vascular ectasia.

Gastric antral vascular ectasia, or 'watermelon stomach', is a rare but important cause of gastrointestinal blood loss and anaemia, which has characteristic endoscopic and histological features. The pathogenesis of this condition remains unclear; however, many associated disorders have been documented. Various medical, surgical and endoscopic therapeutic modalities have been attempted with variable success. Leading contenders for the therapeutic modality of choice include hormonal therapy, endoscopic Nd:YAG laser and argon plasma coagulation. Randomized controlled trials to identify the ideal treatment method are lacking at present.
