- W4225527385 abstract "Upper gastrointestinal endoscopy is currently the gold standard for detection of esophageal varices; the finding of esophageal varices confirms portal hypertension. The measurement of hepatic venous pressure gradient provides information regarding the presence and severity of portal hypertension, risk for variceal hemorrhage, outcomes after abdominal surgery, and hepatic decompensation. The causes of portal hypertension are categorized as presinusoidal, sinusoidal, or postsinusoidal based on the site of increased resistance to portal venous flow. Portal hypertensive gastropathy (PHG) accounts for up to 25% of all chronic gastrointestinal bleeding in patients with cirrhosis and 10% of all episodes of acute bleeding. The medical management of acute gastrointestinal bleeding from PHG is similar to that of variceal hemorrhage, with resuscitation, vasoactive agents, and antibiotics. Treatment includes obliteration of the bleeding ectopic varix and/or portal decompression. Varices develop mainly at the gastroesophageal junction, where veins of the portal circulation connect with veins draining into the azygous system." @default.
