Bleeding esophageal varices are enlarged veins in the walls of the lower part of the esophagus (the tube that connects your throat to your stomach) that bleed.
Scarring (cirrhosis) of the liver is the most common cause of esophageal varices. This scarring reduces blood flowing through the liver. As a result, more blood flows through the veins of the esophagus.
This extra blood flow causes the veins in the esophagus to balloon outward. If these veins break open, they can bleed severely.
Any type of chronic liver disease can cause esophageal varices.
Varices can also occur in the upper part of the stomach.
People with chronic liver disease and esophageal varices may have no symptoms.
If there is only a small amount of bleeding, the only symptom may be dark or black streaks in the stools.
If larger amounts of bleeding occur, symptoms may include:
Tests to determine where the bleeding is coming from and detect active bleeding include:
Some doctors recommend EGD for patients who are newly diagnosed with mild to moderate cirrhosis. This test screens for esophageal varices and treats them before there is bleeding.
If massive bleeding occurs, the patient may be placed on a ventilator to protect the airways and prevent blood from going down into the lungs.
Treatments for acute bleeding:
Once the bleeding is stopped, varices can be treated with medicines and medical procedures to prevent future bleeding:
Emergency surgery may be used (rarely) to treat patients if other therapy fails. Portocaval shunts or surgery to remove the esophagus are two treatment options, but these procedures are risky.
Patients with bleeding varices from liver disease may need more treatment for their liver disease, including a liver transplant.
Bleeding often comes back without treatment. Bleeding esophageal varices are a serious complication of liver disease and have a poor outcome.
Call your health care provider or go to an emergency room if you vomit blood or have black tarry stools.
Treating the causes of liver disease may prevent bleeding. Preventive treatment of varices with medications such as beta blockers or with endoscopic banding may help prevent bleeding. Liver transplantation should be considered for some patients.
