    Study Notes

    Gastrointestinal Bleeding Overview

    • Acute gastrointestinal bleeding (GIB) is a leading medical emergency, causing 250,000 to 300,000 annual hospitalizations.
    • Mortality rate ranges from 6-8%, with increased risk in elderly patients or those with severe comorbidities.
    • GIB management involves various specialties, including emergency medicine, gastroenterology, and surgery.

    Classification of GIT Bleeding

    • GIT bleeding is classified based on location relative to the ligament of Treitz:
      • Upper GIT bleeding (UGIB): More common than lower GIT bleeding.
      • Lower GIT bleeding (LGIB)
    • Severity of bleeding can be categorized into acute, chronic, intermittent, and occult forms.

    Upper Gastrointestinal Bleeding (UGIB)

    • Defined as bleeding from sources proximal to the ligament of Treitz, occurring four times more frequently than LGIB.
    • Divided into two types:
      • Non-variceal UGIB
      • Variceal UGIB

    Clinical Manifestations

    • Common presentations include:
      • Melena: Dark, tarry stools indicating slow upper GIT bleeding.
      • Hematemesis: Vomiting fresh blood or coffee ground material reflecting rapid blood loss.
      • Hematochezia: Fresh rectal bleeding, suggestive of significant upper GIT blood loss.

    Etiology of UGIB

    • Peptic ulcers: Account for 40% of UGIB cases, with mortality under 5%. Declining incidence due to H. pylori treatment.
    • Portal hypertension: Causes 10-20% of UGIB, primarily from esophageal varices.
    • Vascular anomalies: Such as angioectasias (1-10 mm vessels) and telangiectasias, account for 7% of UGIB.
    • Gastric neoplasms: Contribute to 1% of upper gastrointestinal hemorrhages.
    • Erosive gastritis: Less common cause of severe bleeding but can lead to chronic blood loss.
    • Includes rare causes such as hemobilia and pancreatic malignancy.

    Initial Evaluation and Treatment

    • Key questions to address:
      • Severity assessment.
      • Initial management strategies.
      • Criteria for outpatient discharge after acute bleeding.
      • Hospital admission indications and levels of care (ward vs. ICU).

    Management of Non-Variceal UGIB

    • Pre-endoscopy management:
      • Risk stratification: Use Glasgow-Blatchford Score (GBS) to categorize patients.
        • GBS ≤ 1 indicates low risk and potential outpatient management.
        • Active bleeding cases require ICU admission for monitoring.
    • Hemodynamic stabilization:
      • Early resuscitation significantly lowers mortality and corrects hypovolemia.
      • Preferred fluids: 0.9% saline or balanced crystalloids (e.g., Ringer’s lactate).
      • Nasogastric tube placement is optional for initial assessment but not routinely recommended.
      • Restrictive RBC transfusion approach is standard for non-massive UGIB, using hemoglobin thresholds of > 8 g/dL for specific patient populations.
