MALLORY–WEISS SYNDROME
Galeta C. Clayton
BASICS
DESCRIPTION
  • Partial-thickness intraluminal longitudinal mucosal tear of distal esophagus or proximal stomach
  • Sudden increase in intra-abdominal and/or transgastric pressure causes:
    • Mild to moderate submucosal arterial and/or venous bleeding:
      • May be related to underlying pathology
      • “Mushrooming” of stomach into esophagus during retching has been observed endoscopically.
    • Responsible for ∼5% of all cases of upper GI bleeding
ETIOLOGY
  • Associated with:
    • Forceful coughing, laughing, or retching
    • Lifting
    • Straining
    • Blunt abdominal trauma
    • Seizures
    • Childbirth
    • Cardiopulmonary resuscitation
  • Risk factors:
    • Alcoholics:
      • Especially after recent binge
    • Patients with hiatal hernia
    • Hyperemesis gravidarum
  • Greater bleeding associated with:
    • Portal hypertension
    • Esophageal varices
    • Coagulopathy
DIAGNOSIS
SIGNS AND SYMPTOMS
History
  • Multiple bouts of nonbloody vomiting and/or retching followed by hematemesis:
    • Most bleeding is small and resolves spontaneously.
    • Massive life-threatening hemorrhage can occur.
  • Epigastric pain
  • Back pain
  • Dehydration:
    • Dizzy, light-headed; syncope
Physical-Exam
  • Hematemesis
  • Melena
  • Postural hypotension
  • Shock
ESSENTIAL WORKUP
  • CBC
  • Rectal exam for occult blood
DIAGNOSIS TESTS & NTERPRETATION
Lab
  • Prothrombin time (PT), partial thromboplastin time (PTT), INR
  • Electrolytes, BUN, creatinine, glucose, LFTs
  • Amylase/lipase if abdominal pain
  • Type and cross-match:
    • At least 4 U of packed red blood cells (PRBCs) if bleeding is severe
  • ECG if elderly or with cardiac history
Imaging
  • Upright chest radiograph for free air from esophageal or gastric perforation
  • Upper endoscopy (esophagogastroscopy):
    • Procedure of choice to locate, identify, and treat source of bleeding
DIFFERENTIAL DIAGNOSIS
  • Nasopharyngeal bleeding
  • Hemoptysis
  • Esophageal rupture (Boerhaave syndrome)
  • Esophagitis
  • Gastritis
  • Gastroenteritis
  • Duodenitis
  • Ulcer disease
  • Varices
  • Carcinoma
  • Vascular-enteric fistula
  • Hemangioma
TREATMENT
PRE HOSPITAL
  • Airway control:
    • 100% oxygen or intubate if unresponsive or airway patency in jeopardy
  • If hemodynamically unstable or massive hemorrhage:
    • Initiate 2 large-bore IV catheters.
    • 1 L bolus (peds: 20 mL/kg) lactated Ringer (LR) solution or 0.9% normal saline (NS)
    • Trendelenburg position
INITIAL STABILIZATION/THERAPY
  • ABCs:
    • IV access with at least 1 large-bore catheter; more if unstable
    • Central catheter placement if unstable for more efficient delivery of fluids and monitoring of central venous pressure
    • IV fluids of either 0.9% NS (or LR) at 250 mL/h if stable; wide open if hemodynamically unstable
    • Dopamine for persistent hypotension unresponsive to aggressive fluid resuscitation
  • Large-bore Ewald tube placement with evidence of large amount of bleeding:
    • Safe
    • Will not aggravate Mallory–Weiss tear
    • Lavage blood from stomach with water while patient is on side in Trendelenburg position.
  • Nasogastric (NG) tube placement to check for active bleeding
  • Transfuse O-negative red blood cells immediately if hypotensive and not responsive to 2 L of crystalloid.
  • Most bleeding stops spontaneously with conservative therapy.
ED TREATMENT/PROCEDURES
  • NPO
  • Transfuse PRBCs if unstable or lowering hematocrit with continued hemorrhage.
  • Place Foley catheter to monitor urine output.
  • Monitor fluid status closely.
  • With continuing hemorrhage, arrange for immediate endoscopy:
    • Control bleeding endoscopically via:
      • Electrocoagulation
      • Injection therapy (epinephrine)
      • Band ligation
      • Hemoclips
      • Application of blood-clotting agents
    • Esophageal balloon tamponade
    • Arterial embolization
  • Intravenous vasopressin in massive bleeding and unavailable endoscopy
  • In persistent/unresponsive hemorrhage, angiographic infusion of vasopressin
  • Surgery—last but definitive treatment modality using techniques to oversew bleeding site or perform gastrectomy
  • Failure of above may require gastric arterial embolization in patients of poor surgical risk.
  • Antiemetics for nausea/vomiting
  • Proton pump inhibitors or H
    2
    blockers for gastric acid suppression.
  • Avoid Sengstaken-Blakemore tubes (especially in presence of hiatal hernia).
MEDICATION
  • Dopamine: 2–20 μ/kg/min IV piggyback (IVPB)
  • Ondansetron 4 mg IV
  • Pantoprazole 20–40 mg IV
  • Vasopressin: 0.1–0.5 IU/min IVPB titrating up to 0.9 IU/min as necessary
FOLLOW-UP
DISPOSITION
Admission Criteria
  • ICU admission for:
    • Continued or massive hemorrhage
    • Hemodynamic instability
    • Extreme age
    • Poor underlying medical condition
    • Complications
  • General floor admission for
    • Stable patients with minimal bleed on presentation that has since cleared
    • Patients with risk factors for rebleeding (portal HTN, coagulopathy)
Discharge Criteria
  • History of minimal bleed that has stopped
  • Hemodynamically stable
  • Normal/stable hematocrit
  • Negative or trace heme-positive stool
  • Negative or trace gastric aspirate
Issues for Referral

Consult GI in ED if significant upper GI bleeding or if you suspect that requires urgent endoscopy.

FOLLOW-UP RECOMMENDATIONS

GI follow-up for outpatient endoscopy if clinically stable for discharge.

PEARLS AND PITFALLS
  • Place 2 large-bore IVs for patients with upper GI bleed.
  • For massive GI bleed, initiate blood transfusion early.
  • Contact GI early for emergent endoscopy with significant bleeding.
  • Active bleeding at the time of initial endoscopy and a low initial hematocrit is associated with a complicated clinical course.
  • Rebleeding usually occurs within 24 hr, and is most common in patients with coagulopathies.
