Management of Mallory‑Weiss Tears: Evidence‑Based Recommendations

Risk Stratification

Mallory‑Weiss tears are generally low‑risk lesions with excellent prognosis according to the Rockall scoring system, and most cease bleeding spontaneously. 1
Mortality is rare in patients younger than 40 years but rises to approximately 30 % in patients older than 90 years. 1
Hemodynamic instability defined by a pulse > 100 bpm and systolic blood pressure < 100 mmHg markedly increases the risk of ongoing bleeding and death. 1
Deaths are almost exclusively observed in patients with serious comorbidities such as cardiac failure, ischemic heart disease, renal failure, liver failure, or disseminated malignancy. 1
Endoscopic findings of a clean base or absence of active bleeding are associated with a very low risk of re‑bleeding and mortality. 1
In shocked patients (tachycardia > 100 bpm and systolic < 100 mmHg), urgent endoscopic assessment is recommended. 1

For patients who are hemodynamically stable and have no active bleeding on endoscopy, conservative management with intravenous fluid resuscitation and close vital‑sign monitoring is appropriate. 2
Target a mean arterial pressure > 65 mmHg while avoiding fluid overload. 2
Initiate oral liquids and advance to a regular diet within 24 hours once oral intake is deemed safe. 2
Early discharge can be considered after a successful endoscopy that shows no stigmata of recent hemorrhage. 2

Endoscopic intervention is indicated when active bleeding is visualized, when stigmata of recent bleeding (e.g., visible vessel or adherent clot) are present, or when hemodynamic instability persists despite resuscitation. 2
Injection of a 1:10,000 adrenaline solution around the bleeding point achieves primary hemostasis in up to 95 % of cases. 2
Thermal modalities (heater probe delivering 20–30 J or argon plasma coagulation) are comparable in effectiveness to adrenaline injection. 2
Mechanical hemoclips are especially useful for actively bleeding larger vessels. 2
Approximately 75 % of Mallory‑Weiss tears stop bleeding without any endoscopic therapy. 2

Histamine‑2 receptor antagonists lack convincing evidence for benefit in Mallory‑Weiss bleeding and are not recommended. [3][2]
Proton‑pump inhibitors, while proven effective in peptic‑ulcer hemorrhage, have an unestablished but plausible role in enhancing clot stability after Mallory‑Weiss bleeding; their routine use may be considered on a case‑by‑case basis. [3][2]

Assuming that all Mallory‑Weiss tears require endoscopic therapy leads to unnecessary procedures; most tears resolve spontaneously. 2
Delaying endoscopy in patients with shock (tachycardia > 100 bpm, systolic < 100 mmHg) can worsen outcomes; urgent assessment is essential. 1
Overlooking serious comorbidities can underestimate mortality risk, as these conditions, rather than the tear itself, drive adverse outcomes. 1

The American Gastroenterological Association categorizes Mallory-Weiss tears as low-risk lesions with an excellent prognosis, as indicated by the Rockall scoring system for upper GI bleeding risk assessment 4
Patients with normal vital signs, hemoglobin levels above a certain threshold, and minimal comorbidities can be managed conservatively 4
Assessing for shock, indicated by a pulse above 100 beats/min and systolic BP below 100 mmHg, is crucial as it signifies higher risk and need for more aggressive management 4

For hemodynamically stable patients, admission to a general medical ward with hourly vital sign monitoring is recommended 4
Establishing intravenous access for fluid resuscitation and maintaining a certain level of hemoglobin during resuscitation is essential for patients with severe bleeding and hemodynamic instability 4, 5
Targeting a mean arterial pressure above 65 mmHg while avoiding fluid overload is vital in the management of severe bleeding 5

Early discharge from hospital is appropriate after successful endoscopy with no stigmata of recent hemorrhage 4
Starting with liquids and advancing to a standard hospital diet within 24 hours is recommended once oral food is authorized 6

Addressing underlying causes of vomiting to prevent recurrence is crucial in the management of Mallory-Weiss syndrome 7
Recognizing Mallory-Weiss tears as epiphenomena of recent retching and vomiting rather than primary causes of symptoms in patients with cyclic vomiting syndrome is important 7

Most Mallory-Weiss tears have an excellent prognosis with appropriate management, with mortality almost exclusively restricted to patients with significant comorbidities 4

A Mallory-Weiss tear is typically located posteriorly across the gastroesophageal junction, according to the American College of Radiology 8
Mallory-Weiss tears are mucosal lacerations that occur at or near the gastroesophageal junction, most commonly on the posterior aspect, as noted by the American College of Radiology 8

Mallory-Weiss tears are often associated with forceful retching or vomiting, which causes a sudden increase in intra-abdominal pressure, as reported in the World Journal of Emergency Surgery 9
In the Rockall scoring system for risk assessment of upper GI bleeding, Mallory-Weiss tears are categorized as low-risk lesions with an excellent prognosis, according to Gut 10 and 11
Endoscopic treatments for active bleeding include injection therapy, argon plasma coagulation, hemoclip placement, or band ligation, as described in Gut 12
