Management of Upper Gastrointestinal Bleeding

Initial Assessment and Stabilization

The patient with melena and a positive fecal occult blood test should undergo urgent assessment to identify and potentially treat the source of upper gastrointestinal bleeding, with immediate evaluation of hemodynamic status, including pulse rate and blood pressure to determine if shock is present, defined as pulse >100 beats/min and systolic BP <100 mmHg, according to the American Gastroenterological Association 1
Begin intravenous fluid resuscitation if hemodynamically unstable, with the goal of normalizing blood pressure and heart rate prior to endoscopic evaluation, as recommended by the World Society of Emergency Surgery 2
Transfuse packed red blood cells to maintain hemoglobin above 7g/dL in most patients; consider a threshold of 9g/dL in patients with massive bleeding or significant cardiovascular comorbidities, based on evidence from the World Society of Emergency Surgery 2
Categorize the patient into high or low risk of death based on age, comorbidities, presence of shock, and eventual endoscopic findings, as suggested by the American Gastroenterological Association 1

EGD should be the initial procedure of choice as it has both diagnostic and therapeutic capabilities, according to the American College of Gastroenterology and the American College of Radiology 1, 3
For hemodynamically stable patients without active bleeding, early elective endoscopy (ideally the morning after admission) is appropriate, as recommended by the American College of Gastroenterology 1
For unstable patients or those with evidence of ongoing bleeding, emergency endoscopy should be performed within 24 hours, based on guidelines from the American College of Gastroenterology and the American College of Physicians 1, 4

During EGD, identify the source of bleeding and apply appropriate endoscopic therapy if active bleeding, non-bleeding visible vessel, or adherent clot is found, as recommended by the American College of Gastroenterology and the American College of Physicians 1, 4
Common causes of upper GI bleeding to look for include peptic ulcer disease, gastric erosions, esophagitis, Mallory-Weiss tears, and vascular malformations, according to the American College of Radiology 3
Following successful endoscopic therapy in patients with ulcer bleeding, high-dose omeprazole therapy (80 mg stat followed by infusion of 8 mg hourly for 72 hours) is recommended, based on evidence from the American College of Gastroenterology 5

Elderly patients (>65 years) have significantly higher mortality rates and require more aggressive management, as suggested by the American College of Gastroenterology and the American College of Physicians 1, 4
Patients with significant comorbidities (especially cardiovascular, renal, or liver disease) are at higher risk for complications and mortality, according to the American College of Gastroenterology and the American College of Physicians 1, 4

Available endoscopic treatments include injection therapy, mechanical therapy (endoscopic clips), or ablative therapy (argon plasma coagulation), though efficacy data in some contexts show high rebleeding rates, according to the National Comprehensive Cancer Network 6
If endoscopic therapy is unsuccessful or bleeding recurs, consider angiographic embolization techniques, as suggested by the National Comprehensive Cancer Network 6

External beam radiation therapy can effectively manage both acute and chronic gastrointestinal bleeding when endoscopic and interventional approaches fail, as recommended by the National Comprehensive Cancer Network 6
