Definition

Esophageal varices are abnormally swollen veins in the lining of the tube (esophagus) that goes from the mouth to the stomach.

Causes

Portal hypertension is when pressure builds in the veins that bring blood to the liver. The pressure causes blood to backup into other smaller blood vessels, such as those found in the esophagus. This leads to varices.

This may happen due to:

Risk Factors

Things that raise the risk of this problem are:

Symptoms

A person may not have problems until bleeding starts. Bleeding may not be serious. It may also stop on its own. Signs of bleeding are:

  • Vomiting or coughing up blood that may look like coffee grounds
  • Red, tarry, or very dark stools
  • Lightheadedness
  • Rapid heartbeat

Diagnosis

You will be asked about your symptoms and health history. A physical may be done.

The esophagus may need to be viewed. This can be done with:

Treatment

The goal is to prevent or stop varices from bleeding. Choices are:

Medicines

Medicines may be given to lower blood pressure or cholesterol. This will help lower the risk of bleeding or slow any bleeding that is happening

Procedures

Procedures may be done, such as:

  • Endoscopic band ligation to tie a band around the varices to prevent or stop bleeding
  • Balloon tamponade to pass a balloon through the nose to compress bleeding varices
  • Transjugular intrahepatic portosystemic shunting to connect the portal vein to the hepatic vein using a stent to control bleeding
  • Distal splenorenal shunt to limit bleeding by connecting the main vein in the spleen to the vein in the left kidney

A liver transplant is the only way to completely cure esophageal varices.

Prevention

There are no known guidelines to lower the risk of this problem.
