Endoscopic follow-up study of development of gastric antral vascular ectasia associated with liver cirrhosis.
Gastric antral vascular ectasia is an important cause of chronic gastrointestinal blood loss. However, its development and progression have not yet been clarified. We investigated its early lesions and progression by reviewing endoscopic films of five patients with gastric antral vascular ectasia followed for liver cirrhosis. In all patients, early findings were prepyloric red spots. In two patients, anemia due to gastrointestinal bleeding was already observed when vascular lesions were confined to the distal antrum. In the other three patients, anemia was observed 1-2 years after they showed a diagnostic pattern of gastric antral vascular ectasia. The vascular lesions gradually thickened and extended throughout the antrum, with the complete picture shown in 1.5-5 years. The pattern of distribution was classified into three types: diffuse spotty, diffuse confluent, and striped. These types could be predicted before the complete formation. Gastric antral vascular ectasia associated with liver cirrhosis started as prepyloric red spots and extended to the proximal antrum in various ways and varying time courses of less than 5 years; this entity may cause hemorrhage even in the early stage.
