Comprehensive Diagnostic & Therapeutic Reference Profile
Also known as: Mallory-Weiss syndrome, gastroesophageal laceration syndrome, MWS.
A Mallory-Weiss tear is a non-penetrating, longitudinal mucosal laceration located at the gastroesophageal junction (GEJ) or the gastric cardia. It is a common cause of acute upper gastrointestinal bleeding (UGIB), typically precipitated by a sudden, severe increase in intra-abdominal pressure such as forceful vomiting, retching, or coughing. While most tears heal spontaneously without long-term sequelae, severe lacerations can lead to life-threatening hemorrhage requiring urgent endoscopic intervention.
The primary cause of a Mallory-Weiss tear is a sudden rise in intragastric pressure. Common triggers include:
The pathophysiological mechanism involves a rapid, forceful increase in intra-abdominal pressure against a closed glottis or a tight lower esophageal sphincter (LES).
Complete Blood Count (CBC)
Type: Blood Test
Purpose: To evaluate hemoglobin (Hb), hematocrit (Hct), and platelet levels to assess the severity of blood loss.
Expected Findings: Normal or decreased Hb/Hct (may not reflect acute blood loss immediately due to hemoconcentration); thrombocytopenia if associated with chronic liver disease.
Interpretation: A drop in Hb below 7–8 g/dL suggests a severe bleed requiring packed red blood cell transfusion. Coagulation Panel (PT/INR, aPTT)
Type: Blood Test
Purpose: To rule out coagulopathy or therapeutic anticoagulation that could exacerbate bleeding.
Expected Findings: Normal, or prolonged INR/aPTT in patients with hepatic dysfunction or those on anticoagulants.
Interpretation: Elevated INR (>1.5) requires correction with vitamin K or fresh frozen plasma to facilitate hemostasis. Basic Metabolic Panel (BMP)
Type: Blood Test
Purpose: To assess renal function and electrolyte balance.
Expected Findings: Elevated Blood Urea Nitrogen (BUN) with a normal or mildly elevated creatinine.
Interpretation: A BUN-to-creatinine ratio >30:1 suggests upper gastrointestinal bleeding due to the digestion and absorption of blood proteins.
Esophagogastroduodenoscopy (EGD): Purpose: The definitive gold standard diagnostic and therapeutic modality. Typical Findings: A single, longitudinal, mucosal laceration, ranging from 1 to 4 cm in length, located across the gastroesophageal junction or immediately below it in the gastric cardia. Active oozing, a visible vessel, or an adherent clot may be visualized. Clinical Importance: Confirms the diagnosis and allows for immediate therapeutic intervention to control active bleeding.
Chest X-ray (CXR): Purpose: Performed if transmural esophageal rupture (Boerhaave syndrome) is suspected. Typical Findings: Normal in uncomplicated Mallory-Weiss tears. Clinical Importance: The presence of mediastinal emphysema, pneumothorax, or pleural effusion rules out a simple mucosal tear and indicates a surgical emergency.
The prognosis for a Mallory-Weiss tear is excellent.
The following homeopathic remedies have been historically indicated for symptoms associated with Mallory-Weiss Tear. Selection should be based on individualized symptom totality and constitutional assessment.
