Antral mucosal perfusion is not increased in GAVE

Objectives: Although a common cause of intestinal blood loss, the pathophysiology of gastric antral vascular ectasia (GAVE) is not well understood. We aimed to evaluate gastric antral and body mucosal flow in GAVE patients compared to a control population using laser Doppler flowmetry.Methods: 27 patients with GAVE and 11 control patients without GAVE were evaluated using an endoscopic LDF probe. The probe was placed in the gastric antrum and...
