title: Novel developments in esophageal vascular disorders.
abstract: OBJECTIVE
  Esophageal variceal bleeding is a life-threatening complication of liver cirrhosis. The aim of this review is to discuss the most important studies published in 2007 concerning diagnosis of esophageal varices, primary and secondary prophylaxis and treatment of variceal bleeding.
  
  
  RESULTS
  The specific areas reviewed are the noninvasive or minimally invasive diagnosis of oesophageal varices, prevention of the formation of varices and their progression from small to large, prevention of the first variceal hemorrhage, treatment of acute bleeding episodes and prevention of rebleeding, assessment of costs related to prophylaxis and treatment of variceal bleeding. Multidetector computed tomographic esophagography was found to identify the presence and grade the size of esophageal varices. Portal vein thrombosis was found to be an independent predictor of the aggravation of esophageal varices in patients with cirrhosis and hepatocellular carcinoma. The role of hepatic vein pressure gradient measurement in the prediction of decompensation of cirrhosis has been elucidated.
  
  
  CONCLUSIONS
  Relevant studies are reviewed on the diagnosis and the natural history of esophageal varices, prevention of their formation and growth, prevention of the first variceal bleed, use of hepatic vein pressure gradient to predict the evolution of portal hypertension and to estimate the response to pharmacological treatment, prediction of bleeding, treatment of variceal bleeding and prevention of rebleeding, and cost strategies.
