What is the management for a patient with an upper gastrointestinal (uGI) bleed presenting with coffee ground emesis?

Management of Upper GI Bleed with Coffee Ground Emesis

For a patient presenting with coffee ground emesis, initiate immediate resuscitation if hemodynamically unstable, start high-dose intravenous proton pump inhibitor therapy immediately, and perform upper endoscopy within 24 hours of presentation after initial stabilization. 1

Initial Resuscitation and Stabilization

• Assess hemodynamic stability first – check vital signs, heart rate, blood pressure, and calculate shock index (heart rate/systolic BP); a shock index ≥1 indicates hemodynamic instability requiring aggressive resuscitation 1, 2

• Initiate fluid resuscitation with crystalloids (1-2 liters of normal saline initially) in patients with hemodynamic instability to restore end-organ perfusion and tissue oxygenation 1, 3

• **Transfuse red blood cells when hemoglobin is <80 g/L** in patients without cardiovascular disease; use a higher threshold (typically >80 g/L) for patients with underlying cardiovascular disease 1, 4

• Correct coagulopathy if the patient is on anticoagulants, but do not delay endoscopy for patients receiving vitamin K antagonists or DOACs 1

Risk Stratification

• Calculate the Glasgow Blatchford score – a score of ≤1 identifies very low-risk patients who may not require hospitalization or urgent endoscopy and can potentially be managed as outpatients 1

• Recognize that coffee ground emesis alone has lower predictive value – it is associated with significantly lower endoscopic yield for high-risk lesions (gastric ulcer, duodenal ulcer, varices, malignancy) compared to frank hematemesis 5

• Consider non-GI causes in hemodynamically stable patients with coffee ground emesis and no hemoglobin drop, as they may have other serious conditions (myocardial infarction, pulmonary embolism, sepsis, renal failure) that could be overlooked 6

• Key risk factors for rebleeding and mortality include: age >60 years, shock (HR >100 bpm and systolic BP <100 mmHg), hemoglobin <100 g/L, and significant comorbidities (renal insufficiency, liver disease, malignancy, cardiac disease) 2

Pre-Endoscopic Pharmacological Management

• Start intravenous proton pump inhibitor therapy immediately upon presentation – this may downstage the endoscopic lesion and decrease the need for endoscopic intervention, though it should not delay endoscopy 1, 3

• The recommended regimen is pantoprazole 80 mg IV bolus (or equivalent PPI), which can be followed by continuous infusion if high-risk stigmata are found at endoscopy 2

• Do not routinely use promotility agents before endoscopy to increase diagnostic yield 1

• Consider nasogastric tube placement in selected patients as findings may have prognostic value – bright blood in aspirate is an independent predictor of rebleeding 1, 2

Endoscopic Management Timing and Approach

• Perform upper endoscopy within 24 hours of presentation after initial stabilization for most hospitalized patients 1

• Consider earlier endoscopy (within 12 hours) for high-risk patients with hemodynamic instability, ongoing bleeding, or shock index >1 2, 3

• If the patient remains hemodynamically unstable after initial resuscitation (shock index >1), consider urgent CT angiography to localize bleeding before planning endoscopic or radiological therapy 2

• Endoscopy successfully identifies the bleeding source in 95% of cases and facilitates intervention to achieve hemostasis 1

Endoscopic Therapy Based on Findings

• For high-risk stigmata (active bleeding, visible vessel, adherent clot): use combination endoscopic therapy with epinephrine injection PLUS a second modality (thermocoagulation or clips) – never use epinephrine injection alone 1, 3

• For adherent clots: attempt targeted irrigation to dislodge the clot with appropriate treatment of the underlying stigmata 1

• For low-risk stigmata (clean-based ulcer or flat pigmented spot): endoscopic hemostatic therapy is not recommended 1

Post-Endoscopic Pharmacological Management

• For patients with high-risk stigmata who underwent successful endoscopic therapy: administer high-dose PPI therapy as pantoprazole 80 mg IV bolus followed by 8 mg/hour continuous infusion for exactly 72 hours 2, 3

• After 72 hours: continue with oral PPI twice daily for 14 days, then once daily for a duration dependent on the nature of the bleeding lesion 2, 3

• This high-dose continuous infusion regimen significantly reduces rebleeding rates and mortality compared to H2-receptor antagonists or placebo 2

Hospital Management and Monitoring

• High-risk patients should be hospitalized for at least 72 hours after endoscopic hemostasis in a monitored setting 1, 3

• Selected low-risk patients can be discharged promptly after endoscopy if they have low-risk endoscopic findings and stable hemodynamics 1

• Patients considered low risk for rebleeding after endoscopy can be fed within 24 hours 2, 3

Testing and Secondary Prevention

• Test all patients for Helicobacter pylori and provide eradication therapy if positive, as this reduces ulcer recurrence and rebleeding rates 2, 3

• Note that testing during acute bleeding may have increased false-negative rates; confirmatory testing outside the acute context may be necessary 2

Management of Antiplatelet/Anticoagulant Therapy

• For patients requiring cardiovascular prophylaxis: restart aspirin as soon as cardiovascular risks outweigh GI risks (usually within 7 days) 1, 4

• Aspirin plus PPI therapy is preferred over clopidogrel alone to reduce rebleeding 1, 4

• Continue PPI therapy indefinitely for patients with previous ulcer bleeding who require antiplatelet or anticoagulant therapy 3

Critical Pitfalls to Avoid

• Do not assume coffee ground emesis always indicates significant upper GI bleeding – it has lower positive predictive value and may represent other conditions, particularly in hemodynamically stable patients without hemoglobin drop 6, 5

• Do not use epinephrine injection alone for endoscopic hemostasis – it must always be combined with thermal or mechanical therapy 1, 3

• Do not routinely perform second-look endoscopy – it may be useful only in selected high-risk patients but is not recommended for all 1, 2

• Do not delay endoscopy in patients on anticoagulants – proceed with endoscopy while managing coagulopathy 1
