Overview

Overview
Mallory-Weiss syndrome refers to bleeding from tears in the mucosa at the junction of the stomach and esophagus, usually caused by severe retching, coughing, or vomiting. It is often associated with alcoholism and eating disorders and there is some evidence that presence of a hiatal hernia is a required predisposing condition.
Historical Perspective
In 1929 G. Kenneth Mallory, pathologist (1900-86) and Soma Weiss, physician (1898-1942), first described Mallory-Weiss syndrome. [1].
Classification
There is no established system for the classification of Mallory-Weiss syndrome.
Pathophysiology
It is thought that Mallory-Weiss syndrome is the result of sudden increase in intraabdominal pressure that causes mucosal lacerations. If the tear involves the esophageal venous or arterial Plexus,bleeding occurs.
Causes
Mallory-Weiss syndrome is caused by severe retching, coughing, or vomiting. It is often associated with alcoholism and eating disorders and there is some evidence that presence of a hiatal hernia is a required predisposing condition.
Differentiating Mallory-Weiss syndrome overview from Other Diseases
Mallory-Weiss syndrome must be differentiated from other causes of Upper gastrointestinal bleeding such as PUD, Esophagogastric varices, Severe or erosive gastritis/duodenitis, Angiodysplasia.
Epidemiology and Demographics
Mallory-Weiss syndrome is suggested to be associated with increased age. The incidence of Mallory-Weiss syndrome is 4 per 100,000 individuals. The incidence of Mallory-Weiss syndrome in patients with Upper gastrointestinal bleeding is from 8% to 15%.
Risk Factors
The most potent risk factors in the development of Mallory-Weiss syndrome are Alcohol use and Hiatal hernia. The less potent risk factor in the development of Mallory-Weiss syndrome is age.
Screening
There is insufficient evidence to recommend routine screening for Mallory-Weiss syndrome.
Natural History, Complications, and Prognosis
Natural History
Mallory-Weiss tears heal quickly in the absence of portal hypertensive.
Complications
Hemorrhage, organ ischemia and infarction.
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.
Diagnosis
History and Symptoms
The hallmark of Mallory-Weiss syndrome is acute onset of bloody vomiting. A positive history of forceful vomiting and retching are suggestive of Mallory-Weiss syndrome, but may present as an old blood in the stool with no history of retching.
Physical Examination
Mallory-Weiss syndrome is usually associated with tachycardia, weak pulse and hypotension.
Laboratory Findings
Blood tests, such as a complete blood count (CBC), blood chemistries, blood clotting tests, and liver function tests, are used to assess the condition of the patient.
BUN, creatinine, and electrolyte levels are measured to guide intravenous fluid therapy.
Imaging Findings
If there is mucosal laceration without perforation, it is likely to be occult on CT scan. However, CT may show evidence of hemorrhage or extraluminal gas at the tear site.
Other Diagnostic Studies
Upper endoscopy is the definitive diagnostic study for Mallory-Weiss Syndrome. Tears are located in the esophagogastric junction. The tear usually extends into the cardia and sometimes into the esophagus.
Treatment
Medical Therapy
Treatment of Mallory-Weiss syndrome is usually supportive because persistent bleeding is uncommon. Injection of epinephrine or cauterization may be done to stop bleeding during endoscopy.
Surgery
Surgical oversewing of the tear is reserved for those who fail angiographic therapy.
Prevention
Treatments to relieve vomiting and coughing may reduce risk. Avoidance of excessive alcohol use.

Overview
Mallory-Weiss syndrome was first described in 1929 by G. Kenneth Mallory and Soma Weiss in 15 alcoholic patients. [1]
Historical Perspective
- In 1929 G. Kenneth Mallory, pathologist (1900-86) and Soma Weiss, physician (1898-1942), first described Mallory-Weiss syndrome. Initially it was thought it was associated with Alcoholism.However, with the development of medicine and the invention endoscopy the syndrome has been diagnosed in many patients with no history of alcohol consumption.[2]
- The tear typically occurs after multiple episodes of vomiting or retching, but it may happen after one episode.
- Mallory-Weiss syndrome may have become more common in recently. [3]

Epidemiology and Demographics
Incidence
The incidence of Mallory-Weiss syndrome is 4 per 100,000 individuals.
The incidence of Mallory-Weiss syndrome in patients with Upper gastrointestinal bleeding is from 8% to 15%.[1][2][3]
Age
Mallory-Weiss syndrome is suggested to be associated with increased age.[4] However, most tears happen in patients younger than 40, which suggests that age doesn’t have a major role. Mallory-Weiss syndrome was also reported in infants. [5]
Gender
Mallory-Weiss syndrome occurs more in men than women by a ratio of 2-4:1.

Risk Factors
Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1] Associate Editor(s)-in-Chief: Mohamed Diab, MD [2]
Overview
The most potent risk factors in the development of Mallory-Weiss syndrome are Alcohol use and Hiatal hernia. The less potent risk factor in the development of Mallory-Weiss syndrome is age.
Common Risk Factors
- Alcohol use: 40% to 80% of patients with Mallory-Weiss syndrome has a history of heavy alcohol use which lead to vomiting.[1][2][3][4][5]
- Hiatal hernia: It is still unclear if it is a risk factor or not. It is reported in 40% to 80% of patients with Mallory-Weiss syndrome but big case-control study found no big difference in prevalence of hiatal
hernia between patients with Mallory-Weiss syndrome and controls.[2][6]
Less Common Risk Factors
- Age: Mallory-Weiss syndrome is suggested to be associated with increased age.[7] However, most tears happen in patients younger than 40, which suggests that age doesn’t have a major role. Mallory-Weiss syndrome was also reported in infants. [8]

Overview
Mallory-Weiss tears heal quickly in the absence of portal hypertensive. 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.
Natural History
Mallory-Weiss tears heal quickly in the absence of portal hypertensive. Patients should be assessed for hemodynamic stability and determine the need for fluid resuscitation and/or blood transfusion.
Complications
- Hemorrhage
- Organ ischemia and infarction
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.
- Patients do not require repeat endoscopic evaluation to document healing.
- Approximately 40% to 70% of patients with bleeding Mallory-Weiss syndrome require blood transfusions.[1][2]
- The mortality rate is approximately 5% and depends on the age and the presence of coexisting medical conditions.
