Mallory-Weiss tear

Mucosal lacerations - gastroesophageal junction

A Mallory-Weiss tear occurs in the mucous membrane of the lower part of the esophagus or upper part of the stomach, near where they join. The tear may bleed.

Causes

Mallory-Weiss tears are most often caused by forceful or long-term vomiting or coughing. They may also be caused by epileptic convulsions.

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

Symptoms

Symptoms may include:

Exams and Tests

Tests may include:

  • 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. The tear may also be fixed by clips that are put in during an EGD. 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 large, blood transfusions may be needed. In most cases, bleeding stops without treatment within a few hours.

Outlook (Prognosis)

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

Possible Complications

Hemorrhage (loss of blood)

When to Contact a Medical Professional

Contact 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.

  • Digestive system - illustration

    The esophagus, stomach, large and small intestine, aided by the liver, gallbladder and pancreas convert the nutritive components of food into energy and break down the non-nutritive components into waste to be excreted.

    A Mallory-Weiss tear results from prolonged and forceful vomiting, coughing or convulsions. Typically the mucous membrane at the junction of the esophagus and the stomach develops lacerations which bleed, evident by bright red blood in vomitus, or bloody stools. It may occur as a result of excessive alcohol ingestion. This is an acute condition which usually resolves within 10 days without special treatment.
