Upper Gastrointestinal Tract Bleeding Quiz

Study Notes

Upper Gastrointestinal Tract (UGIT) Bleeding Overview

UGIT bleeding refers to gastrointestinal bleeding occurring proximal to the ligament of Treitz, affecting the esophagus, stomach, and duodenum.

Causes of UGIT Bleeding

Esophageal Causes

Reflux esophagitis
Esophageal varices
Mallory Weiss tear
Esophageal carcinoma

Gastric Causes

Erosive gastritis
Gastric varices
Portal hypertension gastropathy
Peptic ulcer disease (PUD)
Gastric tumors (including carcinoma and gastrointestinal stromal tumors)

Duodenal Causes

Duodenitis
Duodenal diverticulitis
Duodenal peptic ulcer disease
Duodenal carcinoma

Clinical Presentation

Hematemesis: Vomiting blood, categorized by severity:
- Mild to massive, can indicate shock or chronic anemia.
Hematochezia: Fresh blood per rectum indicating massive bleeding, with categorized severity affecting hypovolemia.
Melena: Dark, tarry stool suggesting upper GI bleeding.

Symptoms of UGIT Bleeding

Hematemesis
Coffee ground vomit
Melena
Hematochezia

Peptic Ulcer Disease (PUD) and Bleeding

80% of PUD cases resolve without intervention.
Common symptoms range from asymptomatic to massive hemorrhaging.
Diagnosis involves epigastric tenderness and endoscopy for location confirmation.

Management of UGIT Bleeding

Keep the patient NPO (nothing by mouth) until endoscopy.
Insert a nasogastric tube and perform cold saline lavage.
Establish two peripheral lines and obtain blood samples for cross-matching.
Administer fluid replacement and blood transfusion as needed.
Close monitoring of vital signs and urine output to manage complications.
Use of chemical measures, such as PPI and vasopressin, to prevent bleeding recurrence.

Endoscopic Procedures

Diagnostic and therapeutic to control bleeding and assess rebleeding risk.
Forrest Classification identifies ulcer rebleeding risk:
- Forrest Ia: High risk (arterial spurting)
- Forrest Ib: Moderate risk (oozing)
- Forrest IIa: High risk (visible vessel)
- Forrest IIb: Moderate risk (adherent clot)
- Forrest IIc: Low risk (black spots)
- Forrest III: Low risk (clean ulcer base)

Intervention Techniques

Heat Probe (Diathermy): Utilized for coagulating blood vessels.
Laser Photocoagulation: Non-invasive method using light to induce coagulation.
Injection Treatments: Adrenaline and thrombin to facilitate clotting.
Mechanical Methods: Clips and sutures for hemostasis.

Surgical Interventions Indications

Required for massive bleeding (>10 units), treatment failure, or complications like perforation.
Age over 45 years or visible bleeding vessel increase rebleeding risk.

Rebleeding Insights

Occurs in 5% of cases, most frequently within the first two days post-initial episode.
Mortality rate increases significantly to 25% upon rebleeding.

Summary of Key Diagnostic and Risk Signs

Endoscopic findings such as visible vessels or spurting indicate higher rebleeding risks.
Diagnostic emphasis on identifying ulcers near critical vasculature to mitigate severe outcomes.
