Varices are dilated veins in the distal esophagus or proximal stomach, caused by an increased portal venous pressure, typically at a liver cirrhosis. They can cause massive bleeding without causing other symptoms. The diagnosis is made by endoscopy of the upper GIT. The treatment is carried out primarily by endoscopic banding and i.v. Octreotide. Sometimes the system of a transjugular intrahepatic portosystemic shunt is required.

But cirrhosis of the liver. If the portal pressure for long periods of time higher than that of cava in the Fifth, is venous collaterals develop. The most dangerous collaterals arise in the distal esophagus and gastric fundus in the form of bulging, serpentine extending submucosal vessels, which are known as varices. These varices reduce partially the portal hypertension, but they can rupture and cause massive GI bleeding. The trigger for a Varizenruptur is not known, but bleeding does not occur normally as long as the pressure gradient portalsystemische not is> 12 mmHg. Bleeding disorders due to impaired liver function favoring the bleeding. See also the American College of Gastroenterology’s practice guidelines on variceal hemorrhage in cirrhosis. Tips and risks The placing of feeding tubes in patients with varices does not trigger bleeding. Esophageal varices figure provided by David M.
