What is the appropriate management for hemorrhagic gastritis?

Management of Hemorrhagic Gastritis

Hemorrhagic gastritis should be managed with aggressive resuscitation, early endoscopy within 24 hours, high-dose proton pump inhibitor therapy, and endoscopic hemostasis for high-risk stigmata, while surgery is reserved only as a last resort after all medical and endoscopic options have been exhausted. 1

Initial Resuscitation and Stabilization

• Prioritize aggressive volume resuscitation and hemodynamic stabilization before attempting to identify the bleeding source 1
• Use restrictive red blood cell transfusion thresholds: hemoglobin trigger of 70 g/L (target 70-90 g/L) in stable patients without cardiovascular disease 1
• For patients with cardiovascular disease, use a higher transfusion threshold of 80 g/L (target 100 g/L) 1
• If the patient remains hemodynamically unstable with shock index >1 after initial resuscitation, proceed urgently to CT angiography to localize bleeding before planning intervention 1

Endoscopic Evaluation and Timing

• Perform upper endoscopy (esophagogastroduodenoscopy) within 24 hours of presentation as the primary diagnostic and therapeutic modality 1
• Upper endoscopy successfully identifies the bleeding source in 95% of cases and allows for immediate therapeutic intervention 1
• Emergency endoscopy is indicated for patients with persistent hemorrhage causing hemodynamic instability or requiring repeated transfusions 1

Pharmacologic Therapy

Proton Pump Inhibitors

• Initiate high-dose proton pump inhibitor therapy immediately, even before endoscopy 1
• The optimal regimen is omeprazole 80 mg IV bolus followed by continuous infusion of 8 mg/hour (or 40 mg IV every 8 hours) for high-risk patients 1
• For lower-risk patients, oral omeprazole 40 mg every 12 hours for 5 days is an acceptable alternative 1
• PPI therapy may downstage endoscopic lesions and decrease the need for endoscopic intervention, but should not delay endoscopy 1

Special Consideration for Cirrhotic Patients

• If the patient has cirrhosis, immediately start antibiotic prophylaxis with ceftriaxone 1 g IV once daily for up to 7 days, regardless of whether varices are the source 2
• This reduces infection rates, mortality, and rebleeding in cirrhotic patients with any upper GI bleeding 2

Endoscopic Hemostatic Therapy

Risk Stratification at Endoscopy

• Low-risk stigmata (clean-based ulcer or flat pigmented spot) do not require endoscopic hemostatic therapy 1
• High-risk stigmata (active bleeding or visible vessel) mandate immediate endoscopic hemostatic intervention 1
• For adherent clots, attempt targeted irrigation to dislodge; if a high-risk lesion is revealed underneath, treat it endoscopically 1

Hemostatic Techniques

• Use combination therapy rather than epinephrine injection alone, as epinephrine monotherapy provides suboptimal efficacy 1
• Thermocoagulation (bipolar, heater probe, or argon plasma coagulation) or sclerosant injection combined with epinephrine are first-line endoscopic therapies 1, 3
• Through-the-scope clips are an alternative option for focal bleeding points 1
• For diffuse hemorrhagic gastritis where focal therapy is difficult, argon plasma coagulation has shown effectiveness in achieving hemostasis 3

Management of Refractory or Recurrent Bleeding

• If bleeding recurs after initial endoscopic therapy, perform repeat endoscopy to confirm rebleeding and attempt endoscopic therapy one additional time 1
• Patients who fail two attempts at endoscopic hemostasis should be considered for interventional radiology (angiography with embolization) or surgery 1
• In centers with 24/7 interventional radiology, catheter angiography with embolization should be available within 60 minutes for hemodynamically unstable patients 1

Surgical Intervention

Indications and Timing

• Surgery is an option of last resort, reserved only for patients with uncontrolled hemorrhage despite aggressive medical and endoscopic therapy 4, 5
• No patient should proceed to emergency laparotomy unless every effort has been made to localize bleeding by radiological and/or endoscopic modalities 1
• Avoid surgery between midnight and 7 AM when possible, as outcomes correlate with timing and availability of experienced personnel 1

Surgical Approach

• For hemorrhagic gastritis, non-resectional surgery (such as oversewing bleeding points with vagotomy and pyloroplasty) is preferred over gastric resection 5, 6
• Gastric resection should be avoided in hemorrhagic gastritis due to high postoperative mortality and rebleeding rates 5
• In elderly patients or those with severe comorbidity, perform the minimum operation necessary to stop bleeding 1

Addressing Underlying Causes

Helicobacter pylori

• Test all patients for H. pylori and provide eradication therapy if positive, as this dramatically reduces ulcer recurrence and rebleeding 1
• Testing may have increased false-negative rates during acute bleeding; consider confirmatory testing after the acute episode if initial results are negative 1

NSAID-Associated Bleeding

• Discontinue NSAIDs and aspirin (if used for primary prevention only) immediately 1
• Aspirin for secondary cardiovascular prevention should be restarted as soon as hemostasis is achieved 1
• If NSAIDs must be continued, use the least damaging agent (ibuprofen) with a proton pump inhibitor 1

Alcohol and Stress-Related Factors

• Withdraw offending gastric irritants including alcohol 4, 7, 5
• Provide intensive organ system support for critically ill patients with stress-related hemorrhagic gastritis 7

Common Pitfalls to Avoid

• Do not delay endoscopy for PPI therapy; PPIs should be given concurrently, not sequentially 1
• Do not use promotility agents routinely before endoscopy, as they do not improve diagnostic yield 1
• Do not perform routine repeat endoscopy in all patients after initial successful therapy; reserve it for those with clinical rebleeding 1
• Do not rush to surgery without attempting repeat endoscopy and considering interventional radiology first 1
• Recognize that in hemorrhagic gastritis, bleeding ceases spontaneously with conservative treatment in the majority (75-89%) of cases 4, 5, 8

Post-Hemostasis Management

• Low-risk patients can be fed within 24 hours and may be discharged promptly after endoscopy 1
• Continue PPI therapy and arrange outpatient follow-up for H. pylori testing and eradication if not done during admission 1
• For gastric ulcers, perform repeat endoscopy at 6 weeks to confirm healing and exclude malignancy 1
