Mallory–Weiss syndrome is a condition where high intra-abdominal pressures causes laceration and bleeding of the mucosa called Mallory-Weiss tears. [1] Additionally, Mallory–Weiss syndrome is one of the most common causes of acute upper gastrointestinal bleeding , counting of around 1-15% of all cases in adults and less than 5% in children.
[3] [4] A related condition is Mallory-Weiss syndrome which is only a mucosal tear. A common site of iatrogenic perforation is the cervical esophagus just above the upper sphincter, whereas spontaneous rupture as seen in Boerhaave syndrome perforation commonly occurs in the lower third of the esophagus.

Mallory-Weiss tear; Gastric causes: Gastric ulcer; Gastric cancer; Gastritis; Gastric varices; Gastric antral vascular ectasia; Dieulafoy's lesions; Duodenal causes: Duodenal ulcer; Vascular malformation, including aorto-enteric fistulae. Fistulae are usually secondary to prior vascular surgery and usually occur at the proximal anastomosis at ...
Hematemesis, in contrast to coffee ground vomitus, suggests that upper gastrointestinal bleeding is more acute or more severe, for example due to a Mallory–Weiss tear, gastric ulcer or Dieulafoy's lesion, or esophageal varices. This condition may be a medical emergency and urgent care may be required. [4] [5] [1]
Pathophysiology Receptors on the floor of the fourth ventricle of the brain represent a chemoreceptor trigger zone , known as the area postrema , stimulation of which can lead to vomiting. [ 2 ] The area postrema is a circumventricular organ and as such lies outside the blood–brain barrier ; it can therefore be stimulated by blood-borne drugs ...
Other causes include Mallory-Weiss tears, cancer, and angiodysplasia. [2] A number of medications are found to cause upper GI bleeds. [16] NSAIDs or COX-2 inhibitors increase the risk about fourfold. [16] SSRIs, corticosteroids, and anticoagulants may also increase the risk. [16] The risk with dabigatran is 30% greater than that with warfarin. [17]
Mallory–Weiss syndrome: bleeding tears in the esophagal mucosa, usually caused by prolonged and vigorous retching. [4] Vomiting of ingested blood after bleeding in the mouth, nose, or throat. [4] Tumors of the stomach or esophagus. [4] Irritation or erosion of the lining of the esophagus or stomach. Radiation poisoning. Viral hemorrhagic fevers.
George Kenneth Mallory (February 14, 1900 – April 8, 1986) was an American pathologist chiefly remembered for describing the Mallory–Weiss tear. He was born in Boston , Massachusetts on 14 February 1900, the son of Frank Burr Mallory .
