Mallory-Weiss tear

Alternative Names

Mucosal lacerations - gastroesophageal junction

Causes, incidence, and risk factors

Mallory-Weiss tears are usually caused by forceful or long-term vomiting or coughing . They may also be caused by epileptic convulsions , or anything else that increases the pressure inside the abdomen.

Any condition that leads to violent and lengthy bouts of coughing or vomiting can cause these tears.

Symptoms

• Bloody stools
• Vomiting blood (bright red)

Signs and tests

• CBC possibly showing low hematocrit
• Esophagogastroduodenoscopy (EGD), more likely to be done when there is active bleeding

Treatment

The tear usually heals in a few days without treatment. Surgery is rarely needed. Drugs that suppress stomach acid (proton pump inhibitors or H2 blockers) may be given, but it is not clear if they are helpful.

If blood loss has been great, blood transfusions may be needed. In most cases, bleeding stops without treatment within a few hours.

Expectations (prognosis)

Repeated bleeding is uncommon and the outcome is usually good. Cirrhosis of the liver and problems with blood clotting make future bleeding episodes more likely to occur.

Complications

Hemorrhage (loss of blood)

Calling your health care provider

Call your health care provider if you begin vomiting blood or if you pass bloody stools.

Prevention

Treatments to relieve vomiting and coughing may reduce risk. Avoid excessive alcohol use .
