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.
-
Risk stratification: Use Glasgow-Blatchford Score (GBS) to categorize patients.
-
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.
