Abstract
Duodenal varices are an uncommon disease which occurs along the entire gastrointestinal tract outside the esophagus or stomach. Among ectopic varices, duodenal varices are the most common one. Cirrhosis, hepatic portal hypertension, extrahepatic portal vein occlusion and vasculitis contribute to the pathogenesis of ectopic variceal formation. The unusual pathophysiology, location, diversity and uncertain curative effect of DV are associated with its low detection rate and high mortality of patients. Therefore, the diagnosis and treatment of DV is one of the tough problems in clinical practice. This article reviews the current research advances in pathophysiology, diagnosis and treatment of duodenal varices to provide reference for clinical practice. Key words: Varicose veins; Duodenum; Diagnosis
