[Acute gastrointestinal bleeding].

Area of Science:

• Internal Medicine
• Gastroenterology
• Medical Emergencies

Context:

• Acute gastrointestinal bleeding is a frequent medical emergency, with 85% originating in the upper GI tract.
• Peptic ulcers account for roughly half of all upper GI bleeds, which carry more severe outcomes than lower GI bleeds.

Purpose:

• To outline the diagnostic and therapeutic strategies for acute gastrointestinal bleeding, emphasizing upper GI bleeds.
• To highlight prognostic factors and initial management priorities for patients with GI hemorrhage.

Summary:

• Upper GI bleeding necessitates rapid assessment and resuscitation, with oesophagogastroduodenoscopy (OGD) as the gold standard for localization and intervention.
• Peptic ulcer bleeding is managed endoscopically with mechanical/thermal methods and proton pump inhibitors (PPIs). Variceal bleeding requires specific pre-interventional therapies and endoscopic treatments like ligature therapy or Histoacryl injection.
• Aorto-enteric fistula should be considered in cases of massive hemorrhage with suspected aortic disease.

Impact:

• Provides a concise overview of current management for a common and serious medical condition.
• Aids clinicians in risk stratification, diagnosis, and therapeutic decision-making for gastrointestinal bleeding.
• Emphasizes the importance of endoscopic interventions and targeted therapies for improved patient outcomes.
