Mallory-Weiss syndrome


Mallory-Weiss syndrome is an upper gastrointestinal bleeding (it is the cause of 5-10% of all of them), caused by tears of the esophageal mucosa, without there being perforation of the wall of the esophagus. It usually occurs at the junction between the esophagus and the stomach.

It can appear at any age, being more frequent in males and in alcoholics. It is not serious.

Causes of Mallory-Weiss syndrome

As we have already commented, there is a relationship between alcohol consumption and the appearance of this syndrome.

The fundamental triggers for tears are:

  • violent and repeated vomiting
  • esophageal endoscopies (esophagoscopies, usually in already damaged esophagus)
  • coughing spells or phenomena that increase intra-abdominal pressure. It has also been associated with the consumption of salicylates (such as aspirin).

In some cases it coexists with a hiatal hernia or other gastrointestinal pathologies.

Triggering factors cause the esophageal mucosa to deteriorate to the point of tearing (in one or more than one area, measuring the lesions a few millimeters), a phenomenon that causes bleeding, which is usually mild and does not produce more symptoms.

The associated presence of other digestive lesions, which may be the cause of vomiting, is not uncommon.

Symptoms of Mallory-Weiss syndrome

The upper gastrointestinal bleeding that characterizes this syndrome tends to resolve spontaneously in most cases (80-90%) and, therefore, as we have already said, does not cause any more symptoms.

However, if the blood loss is greater, it will leave the digestive tract through the mouth (hematemesis) and / or the anus (in the form of manes, that is, blood that is already largely or totally digested of black color and odor characteristic). Such bleeding typically occurs after an episode of severe nausea and vomiting.

How is it diagnosed?

After the proper completion of the medical history and physical examination, the key diagnostic method is endoscopy (which can also serve as treatment, as we will discuss later), which allows the lesions to be seen.

Radiology is rarely helpful.

Treatment of Mallory-Weiss syndrome

It should be noted again that the injury most often heals without treatment.

If not, the lost blood volume is replaced and medical treatment with drugs, such as vasopressin, is attempted in principle; If this does not work, cauterization or photocoagulation is used by endoscopy.

Angiographic embolization is used in some cases, and surgery is very rarely necessary.

How can I avoid it?

It is important to point out the importance of a good diet to avoid predisposition of the esophageal mucosa to injury.

Given, in some cases, the relationship between this syndrome and alcohol consumption, it is advisable to limit it to a minimum.

It is convenient to indicate the dire consequences of provoking or forcing vomiting, both for this and for any other situation.

In the event of vomiting of blood or hair, you should go to the doctor without fail.
