Upper Gastrointestinal Bleeding
Summary
Upper gastrointestinal bleeding (UGIB) is defined as bleeding originating proximal to the ligament of Treitz, encompassing the oesophagus, stomach, and duodenum. It is a common medical emergency with significant morbidity and mortality, accounting for approximately 50-100 hospital admissions per 100,000 population annually. The clinical presentation ranges from occult bleeding with iron deficiency anaemia to life-threatening haemorrhage with haemodynamic collapse. UGIB is classified as variceal (15-20%) or non-variceal (80-85%), with the latter predominantly caused by peptic ulcer disease (35-50%), erosive disease (15-25%), and Mallory-Weiss tears (5-15%). Management requires rapid assessment, resuscitation, risk stratification using validated scores (Glasgow-Blatchford, Rockall), and endoscopic intervention within 24 hours for most patients. Mortality has improved significantly with advances in endoscopic therapy, proton pump inhibitors, and organised multidisciplinary care, but remains 6-14% overall and up to 20-30% for variceal bleeding. [1,2,3]
Key Facts
- Definition: Bleeding from a source proximal to the ligament of Treitz (oesophagus, stomach, duodenum)
- Incidence: 50-150 per 100,000 population per year [PMID: 31884016]
- Mortality: Overall 6-14%; variceal bleeding 15-30% [PMID: 29653741]
- Peak Demographics: Elderly (70% are >60 years); Male:Female 2:1
- Commonest Cause: Peptic ulcer disease (35-50% of non-variceal)
- Most Dangerous: Variceal bleeding (highest mortality)
- Pathognomonic Feature: Haematemesis (fresh or coffee-ground) ± melaena
- Gold Standard Investigation: Oesophagogastroduodenoscopy (OGD)
- First-line Treatment: Resuscitation, PPI, endoscopic haemostasis
- Prognosis Summary: Re-bleeding 5-15%; 30-day mortality ~5-10%
Clinical Pearls
Diagnostic Pearl: Melaena indicates at least 50-100mL blood loss and blood has been in the GI tract for >8 hours. Haematochezia usually indicates lower GI source UNLESS patient is haemodynamically unstable (then consider massive upper GI bleed).
Examination Pearl: A rectal examination is MANDATORY - fresh blood on PR with haemodynamic instability often indicates massive upper GI bleed, not lower GI bleed.
Treatment Pearl: PPI infusion (omeprazole 80mg bolus then 8mg/hr for 72 hours) reduces re-bleeding rate after endoscopic therapy - give AFTER endoscopy confirms high-risk stigmata, not before.
Pitfall Warning: Normal NG aspirate does NOT exclude upper GI bleeding - up to 15% of duodenal bleeds have negative NG aspirate due to pyloric closure.
Mnemonic: Causes of UGIB: VOMITED - Varices, Oesophagitis, Mallory-Weiss, Iatrogenic (drugs), Tumour, Erosions, Duodenal/gastric ulcer.
Why This Matters Clinically
Upper GI bleeding is one of the most common GI emergencies encountered in acute medicine. Rapid recognition and appropriate management can be life-saving - delays in resuscitation or endoscopy significantly increase mortality. The condition is increasingly relevant as population ages and anticoagulant/antiplatelet prescribing rises. For examinations, UGIB is a favourite acute scenario testing resuscitation, risk stratification (Glasgow-Blatchford vs Rockall), endoscopic findings interpretation, and management of both variceal and non-variceal causes. Medico-legally, failure to perform timely endoscopy, inadequate resuscitation, or delayed senior involvement in unstable patients are common pitfalls. [4,5]
Incidence & Prevalence
- Incidence: 48-160 per 100,000 population per year (varies by region) [PMID: 31884016]
- Trend: Declining incidence of PUD due to H. pylori eradication and PPI use
- Hospitalisation: ~300,000 admissions per year in USA; ~70,000 in UK
- Seasonal Variation: None significant
- Geographic Variation: Higher in areas with high H. pylori prevalence and NSAID use
- Economic Burden: Significant - average admission costs $5,000-20,000
Demographics
| Factor | Details | Clinical Significance |
|---|---|---|
| Age | 70% are >60 years; median age ~65-70 | Elderly have higher mortality, more comorbidities |
| Sex | Male:Female ~2:1 | Higher PUD and alcohol use in males |
| Socioeconomic | Higher in lower socioeconomic groups | H. pylori, NSAID use, alcohol, delayed presentation |
| Cirrhosis | 15-20% of UGIB is variceal | Highest mortality subgroup |
| NSAID/Aspirin use | 40-50% of PUD bleeds | Modifiable risk factor |
| Anticoagulant use | Increasing prevalence | Complicates management, increases bleeding risk |
Risk Factors
Non-Modifiable Risk Factors:
| Factor | Relative Risk (95% CI) | Mechanism |
|---|---|---|
| Age >60 years | RR 3.0 (2.5-3.6) | More comorbidities, PUD prevalence |
| Male sex | RR 1.5-2.0 | Higher PUD, alcohol, NSAID use |
| Prior GI bleeding | RR 5-10 | Recurrent disease, known varices |
| Cirrhosis/portal HTN | RR 5-15 | Varices, coagulopathy |
| CKD/dialysis | RR 2.5 (2.0-3.2) | Platelet dysfunction, gastric erosions |
Modifiable Risk Factors:
| Risk Factor | Relative Risk (95% CI) | Evidence Level | Intervention Impact |
|---|---|---|---|
| NSAIDs | RR 4-6 | Level 1a | 80% risk reduction with cessation |
| Aspirin | RR 2-3 | Level 1a | PPI co-prescription reduces risk by 70-80% |
| Anticoagulants (warfarin) | RR 2-3 | Level 1b | INR management critical |
| DOACs | RR 0.8-1.2 vs warfarin | Level 1a | Lower major bleeding vs warfarin |
| H. pylori infection | RR 2-4 for PUD | Level 1a | Eradication reduces recurrence by 90% |
| Alcohol excess | RR 2-3 | Level 2a | Abstinence reduces erosive/variceal bleeding |
| Smoking | RR 1.5-2.0 | Level 2a | Cessation improves PUD healing |
| Corticosteroids | RR 2 (especially with NSAIDs) | Level 2a | PPI prophylaxis |
Protective Factors:
- PPI therapy: Reduces NSAID-related GI events by 60-80%
- H. pylori eradication: Reduces PUD recurrence by 80-90%
- COX-2 selective NSAIDs: 50% lower GI events vs non-selective (but CV risk)
Mechanism
Step 1: Mucosal Injury/Vascular Abnormality
- Peptic Ulcer: H. pylori infection and/or NSAID use → mucosal barrier disruption → acid injury to mucosa and submucosa → erosion into blood vessels
- Varices: Portal hypertension (>10mmHg HVPG) → formation of portosystemic collaterals → thin-walled varices in oesophagus/stomach → rupture due to wall tension
- Erosions: Mucosal ischaemia, stress, medications → superficial mucosal damage → capillary bleeding
- Mallory-Weiss: Forceful vomiting → mucosal tear at gastro-oesophageal junction → arterial bleeding from submucosal vessels
- Malignancy: Tumour neovascularisation, necrosis, invasion of vessels
Step 2: Haemorrhage (Seconds to Hours)
- Vessel erosion: Ulcer eroding into arterial vessel (gastroduodenal artery for posterior DU, left gastric for lesser curve GU)
- Variceal rupture: Critical wall tension exceeded → massive haemorrhage (blood loss 500-2000mL in minutes)
- Blood accumulation: In stomach (haematemesis) or passes to small bowel (melaena)
- Haemodynamic response: Tachycardia, peripheral vasoconstriction, initial blood pressure maintained
Step 3: Systemic Response (Minutes to Hours)
- Hypovolaemia: Blood loss >15% blood volume → compensatory tachycardia; >30% → hypotension, shock
- Catecholamine surge: Sympathetic activation → cold extremities, sweating, tachycardia
- Renal response: Aldosterone, ADH release → oliguria, sodium retention
- Metabolic: Tissue hypoperfusion → lactic acidosis
- Clinical correlates: Syncope occurs with rapid blood loss >500mL
Step 4: Natural Haemostasis or Continued Bleeding
- Platelet plug formation: At bleeding site - may stop bleeding in 80% of cases
- Fibrin clot: Stabilises platelet plug
- High-risk stigmata: Active bleeding, visible vessel, adherent clot → high re-bleed risk (30-50%)
- Spontaneous cessation: Most non-variceal bleeds stop spontaneously but may re-bleed
- Variceal bleeding: High re-bleed rate without treatment (60-70% within 6 weeks)
Step 5: Resolution or Complications
- Healing: With acid suppression, ulcer healing occurs over 6-8 weeks
- Re-bleeding: Most occurs within 72 hours; risk predicted by Rockall score
- Perforation: Ulcer may perforate as well as bleed
- Death: From exsanguination, complications of shock (MI, stroke, renal failure)
Classification
Forrest Classification (Peptic Ulcer Bleeding) - ESSENTIAL FOR EXAMS:
| Class | Description | Re-bleed Risk | Treatment |
|---|---|---|---|
| Ia | Spurting arterial bleeding | 90% | Emergency endoscopic therapy |
| Ib | Oozing bleeding | 50% | Endoscopic therapy |
| IIa | Non-bleeding visible vessel | 50% | Endoscopic therapy |
| IIb | Adherent clot | 25% | Consider clot removal + therapy |
| IIc | Flat pigmented spot | 10% | No endoscopic therapy needed |
| III | Clean ulcer base | <5% | No endoscopic therapy needed |
Variceal vs Non-Variceal:
| Feature | Variceal | Non-Variceal |
|---|---|---|
| Proportion | 15-20% | 80-85% |
| Mortality | 15-30% | 5-10% |
| Re-bleeding | Very high without intervention | 5-15% |
| Treatment | Banding/sclerotherapy + vasoactive drugs | Endoscopic haemostasis + PPI |
Anatomical Considerations
Arterial Supply (relevant to ulcer bleeding):
- Gastroduodenal artery: Posterior duodenal ulcers - massive bleeding
- Left gastric artery: Lesser curve gastric ulcers
- Right gastric artery: Pyloric region
- Short gastric arteries: Fundal lesions
Variceal Anatomy:
- Oesophageal varices: Portal vein → coronary (left gastric) vein → oesophageal varices → azygos system
- Gastric varices: GOV1 (extension of oesophageal), GOV2 (extends to fundus), IGV (isolated gastric)

Signs
Red Flags
[!CAUTION] Red Flags — Urgent intervention required if:
- SBP <100mmHg or HR >100bpm
- Active haematemesis with fresh blood
- Syncope or altered mental status
- Signs of shock (cold, clammy, CRT >3 sec)
- Massive transfusion requirement (>4 units RBC)

Structured Approach
General Appearance:
- Level of consciousness (AVPU or GCS)
- Pallor (conjunctival, palmar creases)
- Distress, diaphoresis
- Evidence of chronic liver disease (see below)
Vital Signs - PRIORITY:
- Pulse: Rate (tachycardia >100), rhythm (AF common in elderly)
- Blood pressure: Hypotension (<100 systolic), postural drop (>20mmHg)
- Respiratory rate: Tachypnoea (compensatory, metabolic acidosis)
- Oxygen saturation: May be reduced with shock
- Temperature: Fever suggests infection (SBP, aspiration)
- Urine output: Catheterise if in shock
Cardiovascular:
- Heart sounds, murmurs (chronic anaemia → flow murmur)
- JVP: Low with hypovolaemia; high may indicate cardiac failure
- Peripheral perfusion: CRT, temperature, pulses
Abdominal Examination:
- Inspection: Distension, scars, caput medusae
- Tenderness: Epigastric (PUD), generalised (perforation)
- Masses: Gastric cancer, pancreatic mass
- Organomegaly: Hepatomegaly, splenomegaly (portal HTN)
- Ascites: Shifting dullness (cirrhosis)
Rectal Examination - ESSENTIAL:
- Stool colour: Melaena (black, tarry, offensive), fresh blood, normal
- Masses: Rectal cancer (separate issue)
Signs of Chronic Liver Disease:
- Jaundice
- Spider naevi
- Palmar erythema
- Gynaecomastia
- Testicular atrophy
- Ascites
- Hepatic encephalopathy (flapping tremor, confusion)
- Caput medusae
Special Tests
| Assessment | Technique | Positive Finding | Clinical Significance |
|---|---|---|---|
| Postural BP | Lying then standing for 2 min | SBP drop >20mmHg or HR rise >20 | Significant volume depletion |
| Rectal examination | Insert gloved finger, examine stool | Black, tarry stool (melaena) | Confirms GI bleeding |
| Tilt test | As per postural BP | As above | Alternative method |
| JVP assessment | 45° head elevation | Low JVP | Hypovolaemia |
| CRT | Blanch nailbed 5 seconds | >3 seconds to refill | Poor peripheral perfusion |
First-Line (Bedside)
- ABG/VBG: Lactate (tissue hypoperfusion), pH (acidosis indicates shock)
- Blood glucose: May be elevated with stress
- ECG: Chest pain, arrhythmia (may precipitate MI in elderly with anaemia)
- Urine output: Catheterise - target >0.5mL/kg/hr
Laboratory Tests
| Test | Expected Finding | Purpose |
|---|---|---|
| FBC | Low Hb (may be normal initially), raised MCV (if chronic) | Severity, baseline, transfusion threshold |
| U&Es | Raised urea (blood protein load), normal/raised creatinine (shock) | Urea >20 suggests UGIB vs LGIB; renal function |
| LFTs | Deranged if liver disease | Identifies cirrhosis, synthetic function |
| Coagulation (PT/INR, APTT) | Prolonged in liver disease, warfarin | Guides reversal therapy |
| Group & Screen | Blood typing | For crossmatch if transfusion needed |
| Crossmatch | 2-6 units depending on severity | Prepare for transfusion |
| Lactate | Elevated (>2mmol/L) | Marker of hypoperfusion/shock |
| Fibrinogen | May be low in massive transfusion | Guide replacement therapy |
Key Biochemical Clue:
- Raised urea with normal creatinine: Characteristic of UGIB (protein load from digested blood)
- Urea:Creatinine ratio >100 suggests UGIB
Imaging
| Modality | Findings | Indication |
|---|---|---|
| Erect CXR | Free air under diaphragm | If perforation suspected (peritonitis) |
| CT Angiography | Active contrast extravasation | Massive bleeding, endoscopy failed, identify source |
| Abdominal CT | Mass, liver cirrhosis, ascites | If malignancy suspected |
| Doppler ultrasound | Portal vein thrombosis, cirrhosis | Assess portal hypertension |
| Mesenteric angiography | Active bleeding site | If endoscopy fails, bleeding >0.5mL/min |
Endoscopy (OGD) - THE DEFINITIVE INVESTIGATION
Timing:
- Urgent (<12 hours): Haemodynamically unstable after resuscitation, variceal bleeding suspected
- Early (<24 hours): Most patients with acute UGIB
- Delayed (>24 hours): Low-risk patients (GBS 0-1), may be discharged and outpatient OGD
Findings:
- Source identification: Ulcer, varices, erosions, cancer, Mallory-Weiss
- Forrest classification for ulcers (predicts re-bleed risk)
- Therapeutic intervention if high-risk stigmata

Acute/Emergency Management
Immediate Actions (within first hour):
- ABC assessment - intubate if airway compromise, massive haematemesis
- IV access: 2 x large bore cannulae (16G minimum)
- Bloods: FBC, U&Es, LFTs, coagulation, group & save, crossmatch
- Resuscitation: Crystalloid (avoid >2L); blood if Hb <70g/L or shocked
- Restrict blood transfusion: Target Hb 70-90g/L (over-transfusion increases mortality)
- Correct coagulopathy:
- Warfarin: IV vitamin K 5-10mg + PCC (prothrombin complex concentrate)
- DOACs: Consider idarucizumab (dabigatran) or andexanet (factor Xa inhibitors)
- Platelets if <50 x10⁹/L with active bleeding
- Alert endoscopy team and senior GI/surgical input
- Catheterise: Monitor urine output
Variceal Bleeding - SPECIFIC MANAGEMENT:
- Terlipressin: 2mg IV bolus then 1-2mg every 4-6 hours for up to 5 days
- OR Somatostatin/Octreotide: 50mcg bolus then 50mcg/hr infusion
- Antibiotics: IV ceftriaxone 1g OD for 7 days (reduces infection, mortality)
- Endoscopic band ligation: Within 12 hours - gold standard for oesophageal varices
- Balloon tamponade (Sengstaken-Blakemore): Rescue for uncontrolled bleeding
- TIPS (Transjugular Intrahepatic Portosystemic Shunt): If endoscopic therapy fails
Conservative Management
- NBM: Until endoscopy completed
- IV fluids: Maintain euvolaemia (avoid over-resuscitation)
- Proton pump inhibitor: Evidence for IV PPI AFTER endoscopy with high-risk stigmata
- Nasogastric tube: NOT routinely recommended (doesn't change outcomes, aspiration risk)
Medical Management
| Drug | Dose | Duration | Indication |
|---|---|---|---|
| Omeprazole IV | 80mg bolus → 8mg/hr infusion | 72 hours post-endoscopy | High-risk stigmata (Forrest Ia, Ib, IIa) |
| Esomeprazole IV | 80mg bolus → 8mg/hr | 72 hours | Alternative PPI |
| Oral PPI | Omeprazole 40mg BD | 4-8 weeks | After IV PPI, promote ulcer healing |
| Terlipressin | 2mg IV bolus → 1mg 4-6hrly | Up to 5 days | Variceal bleeding |
| Octreotide | 50mcg bolus → 50mcg/hr infusion | 3-5 days | Alternative vasoactive for varices |
| Antibiotics | Ceftriaxone 1g IV OD | 7 days | Variceal bleed - reduces infection/mortality |
| H. pylori eradication | Triple/quadruple therapy | 7-14 days | If H. pylori positive ulcer |
H. pylori Eradication (if positive):
- First-line: PPI + Clarithromycin 500mg BD + Amoxicillin 1g BD x 7-14 days
- Bismuth quadruple therapy if penicillin allergic or clarithromycin resistance
Endoscopic Management
Techniques for PUD:
- Injection therapy: Adrenaline 1:10,000 (diluted) - stops bleeding temporarily
- Thermal coagulation: Gold probe, heater probe, APC
- Mechanical clips: Haemoclips over visible vessel
- Combination therapy: Adrenaline + clips/thermal - BEST outcomes
Techniques for Varices:
- Band ligation: First-line for oesophageal varices
- Sclerotherapy: Injection of sclerosant (less commonly used now)
- Glue injection: For gastric varices (cyanoacrylate)
Surgical Management (Rare)
Indications:
- Failed endoscopic therapy (2 failed attempts)
- Massive/continued bleeding despite intervention
- Perforation (proceed to laparotomy)
Procedures:
- Under-running of bleeding vessel: For PUD with visible vessel
- Partial gastrectomy: Rarely needed
- Oversewing: For gastric ulcer
Interventional Radiology
- Embolisation: For failed endoscopic therapy, poor surgical candidate
- TIPS: For refractory variceal bleeding
Disposition
- ICU/HDU if: Haemodynamically unstable, massive transfusion, variceal bleeding
- Ward if: Stable post-endoscopy, low-risk Rockall
- Discharge: GBS 0, or stable with low Rockall, follow-up arranged
Immediate (Minutes-Hours)
| Complication | Incidence | Presentation | Management |
|---|---|---|---|
| Hypovolaemic shock | 10-20% of UGIB | Hypotension, oliguria, confusion | Aggressive resuscitation |
| Aspiration pneumonia | 5-10% | Cough, hypoxia, fever, chest crepitations | Antibiotics, may need ITU |
| Myocardial ischaemia/MI | 5% (elderly) | Chest pain, ECG changes, troponin rise | Cardiology input, treat anaemia |
| Cardiac arrest | <1% | PEA, VF | ALS protocol |
| Death from exsanguination | 1-2% | Continued bleeding, CVS collapse | Massive transfusion, surgical/IR intervention |
Early (Days)
- Re-bleeding: 5-15%; highest in first 72 hours; Forrest Ia/Ib/IIa highest risk
- Endoscopy perforation: <1%; surgical emergency if occurs
- Transfusion reactions: Febrile, allergic, TRALI, TACO
- Hospital-acquired infection: Line-related, pneumonia, SBP (cirrhosis)
- Acute kidney injury: Pre-renal from hypovolaemia
- Hepatic encephalopathy: In cirrhosis - blood is protein load
- Electrolyte disturbances: From resuscitation, transfusion
Late (Weeks-Months)
- Recurrent bleeding: 5-10% at 1 year; test/treat H. pylori to prevent
- Peptic ulcer complications: Perforation, stricture (gastric outlet obstruction)
- Iron deficiency anemia: Chronic blood loss if source unidentified
- Oesophageal stricture: Post banding/sclerotherapy
- Hepatorenal syndrome: In cirrhosis triggered by variceal bleed
- Post-transfusion iron overload: Multiple transfusions
Natural History
Without treatment, mortality from acute UGIB would approach 30-40%. Even with modern management, overall mortality remains 6-14%, reflecting the elderly, comorbid population affected. Re-bleeding is the most important predictor of mortality - patients who re-bleed have 10x higher mortality than those who don't.
Outcomes with Treatment
| Variable | Outcome |
|---|---|
| Overall 30-day mortality | 6-14% |
| Variceal bleeding mortality | 15-30% |
| Non-variceal bleeding mortality | 5-10% |
| 6-week mortality (varices) | 20-40% |
| Re-bleeding rate | 5-15% (non-variceal); 60-70% (variceal without treatment) |
| Need for surgery | <5% (declining with improved endoscopy) |
| ICU admission rate | 10-20% |
| Length of stay | Median 3-5 days |
Prognostic Factors
Good Prognosis:
- Young age (<60 years)
- No comorbidities
- Haemodynamically stable
- Mallory-Weiss tear (low re-bleed rate)
- Forrest III (clean base ulcer)
- Low Rockall score (≤2)

- Haemodynamic instability at presentation
- Variceal bleeding
- Forrest Ia (spurting arterial bleeding)
- High Rockall score (≥6)
- Failed endoscopic therapy

What is Upper GI Bleeding?
Upper gastrointestinal (GI) bleeding means bleeding from somewhere in the upper part of your digestive system - the oesophagus (food pipe), stomach, or first part of the small intestine (duodenum). This can be a serious emergency if a lot of blood is lost quickly.
The blood might come out as vomit (which can be red or look like coffee grounds) or in your stools (which turn black and sticky like tar - called melaena).
Why does it happen?
The most common causes are:
- Stomach ulcers or duodenal ulcers: Open sores that erode into blood vessels
- Varices: Swollen veins in the oesophagus that can burst (usually due to liver disease)
- Gastritis: Inflammation of the stomach lining from medications (like ibuprofen) or infection
- Mallory-Weiss tear: A small tear in the food pipe caused by forceful vomiting
How is it treated?
-
Fluids and blood: If you've lost a lot of blood, you'll receive fluids through a drip and possibly blood transfusions to replace what you've lost.
-
Camera test (endoscopy): A thin tube with a camera is passed down your throat to find where the bleeding is coming from and treat it at the same time.
-
Medications: Acid-suppressing drugs (like omeprazole) help ulcers heal. Other medications can help reduce blood flow to the bleeding area.
-
Surgery: Rarely needed, only if the bleeding can't be stopped with other treatments.
What to expect
- You'll be kept nil by mouth until the camera test is done
- You may need to stay in hospital for a few days
- You'll likely go home on acid-suppressing tablets for several weeks
- Follow-up tests may be needed to check for infection (H. pylori) or ensure healing
When to seek help
Call 999 or go to A&E immediately if you:
- Vomit blood (red or dark/coffee-ground)
- Pass black, tarry stools
- Feel faint, dizzy, or like you might pass out
- Have fast heartbeat or feel confused
- Have severe stomach pain

Common Exam Questions
Questions that frequently appear in examinations:
-
MRCP Part 1: "A 58-year-old man presents with melaena and a Hb of 65g/L. His Rockall score is 4. What is the most appropriate transfusion target?"
-
MRCP Part 2/PACES: "Describe the Forrest classification and its prognostic significance"
-

-
MCQ: "Which of the following is NOT a component of the Glasgow-Blatchford Score?" (Answer: Age - only Rockall includes age)
-
Viva: "Discuss the evidence for tranexamic acid in upper GI bleeding"
Viva Points
Opening Statement:
"Upper gastrointestinal bleeding is defined as bleeding proximal to the ligament of Treitz and is classified as variceal or non-variceal. It is a common emergency with 6-14% mortality. Management involves rapid resuscitation with restrictive transfusion, risk stratification using Glasgow-Blatchford score, and endoscopy within 24 hours. Peptic ulcer bleeding is treated with endoscopic dual therapy and IV PPI; variceal bleeding requires terlipressin, antibiotics, and band ligation."
Key Facts to Mention:
- Incidence 50-150 per 100,000; mortality 6-14%
- 80-85% non-variceal (PUD most common), 15-20% variceal
- GBS 0 = low risk, can consider outpatient management
- Transfuse if Hb <70g/L (restrictive strategy improves outcomes)
- Endoscopy within 24 hours (12 hours if variceal)
Classification to Quote:
- "Forrest classification predicts re-bleeding risk: Ia/Ib are active bleeding requiring treatment; IIa (visible vessel) has 50% re-bleed risk; III (clean base) has <5% risk"
- "Glasgow-Blatchford is pre-endoscopy; Rockall is post-endoscopy"
Evidence to Cite:
- "Villanueva et al showed restrictive transfusion (Hb trigger <70) reduced mortality vs liberal transfusion in UGIB"
- "HALT-IT trial showed tranexamic acid provides NO mortality benefit in GI bleeding"
- "Sung et al demonstrated IV PPI after endoscopy reduces re-bleeding by 60-70%"
Structured Answer Framework:
- Definition and Epidemiology (30 seconds)
- Causes - Variceal vs Non-Variceal (30 seconds)
- Clinical Presentation (30 seconds)
- Risk Stratification (45 seconds)
- Management - Resuscitation & Endoscopy (60 seconds)
- Prognosis (15 seconds)
Common Mistakes
What fails candidates:
- ❌ Not knowing the difference between GBS and Rockall scores
- ❌ Over-transfusing (trigger Hb should be <70-80, not <100)
- ❌ Forgetting terlipressin and antibiotics for variceal bleeding
- ❌ Not knowing the Forrest classification
- ❌ Recommending tranexamic acid (HALT-IT showed no benefit)
- ❌ Confusing variceal and non-variceal management
Dangerous Errors to Avoid:
- ⚠️ Delaying endoscopy in unstable patient
- ⚠️ Ignoring haemodynamic instability
- ⚠️ Forgetting to reverse anticoagulation in active bleeding
- ⚠️ Not involving senior team early for variceal bleeding
Outdated Practices (Do NOT mention):
- Tranexamic acid for GI bleeding — HALT-IT showed no benefit
- Liberal transfusion targets (Hb <100) — Increases mortality
- Routine NG tube insertion — Does not improve outcomes
- H2-receptor antagonists — PPIs are superior
Examiner Follow-Up Questions
Expect these follow-up questions:
-
"What is the Glasgow-Blatchford score used for?"
- Answer: Pre-endoscopy risk stratification. Predicts need for intervention. Score of 0 identifies very low-risk patients who may be managed as outpatients.
-
"How would you manage anticoagulated patient with GI bleeding?"
- Answer: Withhold anticoagulant. Warfarin: IV vitamin K 5-10mg + PCC if INR >5 or severe bleeding. DOAC: consider specific reversal (idarucizumab for dabigatran, andexanet for factor Xa inhibitors) if life-threatening. Resume anticoagulation when safe - timing depends on indication and bleeding risk.
-
"What is the evidence for PPI therapy in UGIB?"
- Answer: Pre-endoscopy PPI does not reduce mortality or re-bleeding. POST-endoscopy high-dose IV PPI (80mg bolus + 8mg/hr x 72h) significantly reduces re-bleeding (Sung et al - 6.7% vs 22.5%). Give AFTER endoscopy confirms high-risk stigmata.
-
"When would you consider TIPS?"
- Answer: For refractory variceal bleeding after failed endoscopic therapy (2 attempts). Also consider early/pre-emptive TIPS in high-risk cirrhotic patients (Child-Pugh B with active bleeding or C<14) within 72 hours - evidence from early TIPS trials.
-
"What are the components of the Rockall score?"
- Answer: Age (0-2), Shock status (0-2), Comorbidity (0-3), Endoscopic diagnosis (0-2), Major stigmata of recent haemorrhage (0-2). Maximum 11 points. Score ≤2 low risk; ≥8 high risk.
-
"How do you differentiate upper from lower GI bleeding clinically?"
- Answer: UGIB: Haematemesis (fresh/coffee-ground), melaena; raised urea:creatinine ratio (>100). LGIB: Fresh PR bleeding (haematochezia), normal urea. BUT: Massive UGIB can present with haematochezia + shock. PR exam essential in all GI bleeds.
-
"What is the difference between Type 1 and Type 2 gastric ulcers?"
- Answer: Johnson classification: Type I (lesser curve, not acid-related), Type II (body + duodenal, acid-related), Type III (prepyloric, acid-related), Type IV (high lesser curve near GEJ). Types II-III have high acid; Type I low acid.
-
"Describe the management of a Dieulafoy lesion"
- Answer: Rare cause (~1-2% UGIB). Large submucosal artery with minimal ulceration. High re-bleed risk. Endoscopic therapy: mechanical clips preferred (more durable), adrenaline injection, APC. May require repeat endoscopy or surgery/angioembolisation if refractory.
Additional Viva Scenarios
Scenario 1: Unstable Variceal Bleeding
"A 52-year-old man with known alcohol-related cirrhosis (Child-Pugh B) presents with massive haematemesis. He is confused, BP 85/50, HR 125, cold and clammy. What is your management?"
Structured Answer:
-
Airway: This patient is confused with massive haematemesis - high aspiration risk. Call anaesthetics for potential intubation before endoscopy. Left lateral position while waiting.
-
Breathing/Circulation: High-flow oxygen. 2x large bore IV access. Bloods urgently including crossmatch 6 units. Crystalloid initially (avoid >2L), transfuse to Hb 70-80g/L. This is variceal until proven otherwise.
-
Specific therapy:
- Terlipressin 2mg IV bolus NOW
- Ceftriaxone 1g IV (reduces mortality)
- Correct coagulopathy if possible (avoid overcorrection in cirrhosis)
-
Endoscopy: Urgent within 12 hours after initial stabilisation. Band ligation for oesophageal varices.
-
If bleeding continues: Sengstaken-Blakemore tube as bridge. Contact hepatology for TIPS (within 72 hours in high-risk Child B/C).
-
Post-endoscopy: Continue terlipressin for 5 days, propranolol for secondary prevention, surveillance OGD.
Scenario 2: Peptic Ulcer with Visible Vessel
"A 68-year-old woman on aspirin and ibuprofen for osteoarthritis presents with melaena. OGD reveals a 1.5cm gastric ulcer with a non-bleeding visible vessel. What is your management?"
Structured Answer:
-
Endoscopic therapy: This is Forrest IIa (50% re-bleed risk without therapy). Dual therapy with adrenaline injection + haemoclips OR adrenaline + thermocoagulation.
-
Post-endoscopy: IV PPI infusion (omeprazole 80mg bolus then 8mg/hr x 72 hours) - Sung et al evidence.
-
Medications: Stop ibuprofen permanently. Discuss aspirin with cardiology - if primary prevention, stop; if secondary prevention (prior MI/stent), may need to continue with PPI cover.
-
H. pylori: Test (CLO test/stool antigen) and treat if positive.
-
Monitoring: Monitor for re-bleeding (continued melaena, haemodynamic instability). Consider repeat OGD in 24-48 hours if high-risk for re-bleeding.
-
Discharge: On PPI (omeprazole 40mg BD) for 8 weeks. Repeat OGD to confirm healing and exclude malignancy (gastric ulcers can be malignant).
Scenario 3: Low-Risk UGIB
"A 45-year-old man presents with coffee-ground vomit after a night of heavy drinking. He had severe retching before the vomiting. He is haemodynamically stable. Hb 138g/L. What is your management?"
Structured Answer:
-
Assessment: This sounds like Mallory-Weiss tear (history of vomiting/retching then haematemesis). Stable haemodynamics, normal Hb.
-
Risk score: Glasgow-Blatchford Score: Urea normal (0), Hb normal (0), BP normal (0), no melaena (0), no syncope (0), no liver/heart disease (0). GBS = 0.
-
Management: GBS 0 is very low risk. Can be considered for outpatient management with early outpatient OGD (within 24 hours) or discharge with PPI and return precautions.
-
Advice: Return if fresh haematemesis, melaena, light-headedness, or any concerning symptoms.
-
Follow-up: Most Mallory-Weiss tears heal spontaneously. PPI for symptomatic relief.
Specific Causes - Extended Detail
Peptic Ulcer Disease (35-50% of non-variceal UGIB):
Aetiology:
- H. pylori infection: 70-80% of DU, 60-70% of GU
- NSAIDs/Aspirin: 20-25% of PUD; risk increased 4-6x
- Stress ulcers (ICU patients): Cushing's ulcer (brain injury → ↑acid); Curling's ulcer (burns → mucosal ischaemia)
- Zollinger-Ellison syndrome: Gastrin-secreting tumour → multiple ulcers, often atypical locations
Locations and Arterial Supply:
- Duodenal ulcer (first part): Gastroduodenal artery erosion → massive bleeding
- Gastric ulcer (lesser curve): Left gastric artery
- Posterior DU: Most dangerous location for bleeding
- Giant ulcers (>2cm): Higher complication rate
H. pylori Testing:
- Acute setting: CLO test (urease test) on biopsy - may have false negatives with recent PPI
- Alternative: Stool antigen test, urea breath test (after PPI stopped)
- Must test ALL PUD patients and eradicate if positive
Oesophageal Varices:
Pathophysiology:
- Portal hypertension: HVPG >10mmHg → variceal formation; >12mmHg → bleeding risk
- 40-60% of cirrhotics have varices; 30% will bleed
- Wall tension: ∝ (pressure × radius) / wall thickness → large varices at high pressure rupture
Classification:
- Grade 1: Small, straight veins
- Grade 2: Enlarged, tortuous, <1/3 of lumen
- Grade 3: Large, occupying >1/3 of lumen
- Red wale marks: High-risk stigmata for bleeding
Primary Prevention:
- All cirrhotics should have screening OGD
- Large varices (Grade 2-3) or red wale marks: Non-selective beta-blocker (propranolol, carvedilol)
- If beta-blocker intolerant: Prophylactic banding
Secondary Prevention:
- Non-selective beta-blocker (propranolol 40-160mg/day, target HR <60)
- Repeat banding until varices eradicated (every 1-2 weeks)
- Combination: Beta-blocker + banding is superior
Gastric Varices:
Classification (Sarin classification):
- GOV1: Continuation of oesophageal varices along lesser curve - treat as oesophageal
- GOV2: Extension to gastric fundus - cyanoacrylate glue injection
- IGV1: Isolated in fundus - cyanoacrylate; consider TIPS/BRTO
- IGV2: Isolated elsewhere in stomach
Treatment:
- Glue injection (cyanoacrylate histoacryl) for GOV2/IGV1
- Band ligation less effective for gastric varices
- TIPS: For refractory/recurrent gastric variceal bleeding
- BRTO (Balloon-occluded Retrograde Transvenous Obliteration): Alternative to TIPS
Mallory-Weiss Tear:
- Classically: Alcohol binge → retching/vomiting → haematemesis
- Location: Gastro-oesophageal junction (mucosal tear)
- Usually self-limiting (80-90% stop spontaneously)
- Endoscopic therapy only if active bleeding
- Low re-bleed risk (<5%)
- PPI not strictly necessary but often given for symptom relief
Oesophagitis/Erosive Disease:
- LA Grade A-D classification
- Usually minor bleeding (iron deficiency anaemia rather than acute UGIB)
- Treat with PPI; address underlying cause
- If severe ulcerative oesophagitis: exclude malignancy
Gastric Malignancy:
- 2-4% of UGIB
- Risk factors: H. pylori, smoking, family history, pernicious anaemia
- Often presents with weight loss, anaemia, anorexia
- Biopsy essential (multiple biopsies from ulcer edge)
- All gastric ulcers need repeat OGD to confirm healing and exclude cancer
- Endoscopic therapy may be needed for bleeding but surgery for definitive treatment
Angiodysplasia/Vascular Ectasias:
- More common in elderly, renal failure, von Willebrand disease
- Cherry-red flat lesions at endoscopy
- Can cause chronic blood loss rather than massive bleeding
- Treat with APC (argon plasma coagulation)
- Recurrence common; may need repeat treatment
Dieulafoy Lesion:
- Rare (~1-2%) but important cause
- Large submucosal artery with minimal overlying ulceration
- Location: Typically lesser curve, 6cm from GEJ
- Intermittent massive bleeding; may be hard to locate
- Treatment: Haemoclips, thermocoagulation, injection
- High re-bleed rate; may need surgery/angioembolisation
Special Populations
Elderly (>80 years):
- Higher mortality (10-20% vs 5% in younger)
- More comorbidities affecting management
- Higher aspirin/anticoagulant use
- Atypical presentations (confusion, collapse)
- Lower threshold for admission and monitoring
- Be cautious of transfusion targets (avoid TACO)
Cirrhotic Patients:
- Coagulopathy: Do NOT aim for normal INR (synthetic dysfunction, not true coagulopathy)
- Thrombocytopenia: Platelets >50 for active bleeding
- Infection: Antibiotics reduce mortality - give routinely
- Hepatic encephalopathy: Blood is protein load - lactulose/rifaximin
- Hepatorenal syndrome: Monitor renal function closely
- Child-Pugh/MELD score guides prognosis
Anticoagulated Patients:
| Anticoagulant | Reversal | Notes |
|---|---|---|
| Warfarin | Vitamin K 5-10mg IV + PCC 25-50 units/kg | Target INR <1.5 |
| Dabigatran | Idarucizumab 5g IV | Specific reversal agent |
| Rivaroxaban/Apixaban | Andexanet alfa Or PCC 50 units/kg | Andexanet if available |
| Heparin | Protamine sulfate | 1mg per 100 units heparin |
| LMWH | Protamine (partial reversal) | 50-60% reversal |
When to Resume Anticoagulation:
- Depends on indication (AF vs mechanical valve vs recent VTE)
- Low bleeding risk (Forrest IIc-III): 48-72 hours
- High bleeding risk (Forrest Ia-IIa): 7-14 days
- Discuss with haematology/cardiology as appropriate
Pregnancy:
- UGIB rare in pregnancy
- Common causes: Mallory-Weiss (hyperemesis), oesophagitis, PUD
- Endoscopy safe (preferably left lateral position, avoid propofol in first trimester)
- PPI safe in pregnancy
- Foetal monitoring if significant bleeding
Massive Transfusion Protocol
Definition: Transfusion of ≥10 units pRBC in 24 hours, or 4+ units in 1 hour
Activation Criteria:
- Active bleeding with haemodynamic instability
- Anticipated need for ongoing transfusion
- Hb rapidly falling despite transfusion
Protocol:
- Activate massive transfusion protocol (MTP) with blood bank
- Initial pack: 4 units pRBC + 4 units FFP + 1 platelet pool (may vary by institution)
- Ratio: Target 1:1:1 (pRBC:FFP:platelets) based on trauma data
- Adjuncts: Calcium (citrate binds calcium), fibrinogen concentrate if fibrinogen <1.5
- Point-of-care testing: TEG/ROTEM to guide component therapy
- Avoid hypothermia (blood warmer), acidosis (correct shock)
- Surgical/IR intervention if bleeding source not controlled
Complications of Massive Transfusion:
- Hypothermia
- Hypocalcaemia (citrate toxicity)
- Hyperkalaemia (stored blood has high K+)
- Coagulopathy (dilutional, consumptive)
- TACO (transfusion-associated circulatory overload)
- TRALI (transfusion-related acute lung injury)
- Iron overload (chronic transfusion)
Discharge Planning and Follow-Up
Before Discharge:
- Haemodynamically stable for >24 hours
- No active bleeding (no fresh melaena)
- Eating and drinking
- Oral PPI prescribed (4-8 weeks)
- H. pylori test result available or arranged
- Medication review (stop NSAIDs, review anticoagulation)
- Patient education on warning signs
Follow-Up:
- GP within 1 week
- Repeat OGD for gastric ulcers (exclude malignancy) - typically 8 weeks
- Confirm H. pylori eradication (if treated) - stool antigen 4+ weeks after treatment
- Variceal screening/surveillance as per hepatology protocol
Patient Education:
- Avoid NSAIDs permanently (or with strong PPI protection if essential)
- Signs of re-bleeding: Black stools, vomiting blood, dizziness
- Take PPI as prescribed
- H. pylori treatment importance
- Alcohol advice (especially if varices)

MCQ Practice Questions
Question 1: A 62-year-old man presents with haematemesis. He has a history of atrial fibrillation on apixaban. His Glasgow-Blatchford Score is 12. Which of the following is the MOST important initial step? A. Immediate endoscopy B. IV omeprazole infusion C. Reversal with andexanet alfa D. Resuscitation with IV fluids and blood products E. CT angiography Answer: D - Resuscitation takes priority. Haemodynamic stabilisation must precede all other interventions. Anticoagulant reversal is considered for life-threatening bleeding after resuscitation is initiated.
Question 2: Which of the following Forrest classifications has the HIGHEST risk of rebleeding without endoscopic therapy? A. Forrest Ia (spurting haemorrhage) B. Forrest IIa (visible vessel) C. Forrest IIb (adherent clot) D. Forrest IIc (flat pigmented spot) E. Forrest III (clean base) Answer: A - Forrest Ia (spurting haemorrhage) has 90% rebleeding risk without intervention. Forrest Ib (oozing) 10-30%, IIa 50%, IIb 25-30%, IIc 7-10%, III <5%.
Question 3: A 55-year-old cirrhotic patient with Child-Pugh C cirrhosis presents with massive variceal haemorrhage. Despite two endoscopic band ligation attempts, bleeding continues. What is the NEXT most appropriate step? A. Repeat band ligation B. Balloon tamponade as bridge to TIPS C. Emergency surgery D. Increase terlipressin dose E. CT angiography with embolisation Answer: B - Balloon tamponade (Sengstaken-Blakemore or Minnesota tube) is a temporising measure for refractory variceal bleeding as a bridge to TIPS. Surgery carries very high mortality in decompensated cirrhosis.
Question 4: Which of the following drugs has been shown in a large RCT to provide NO mortality benefit in upper GI bleeding? A. Terlipressin B. Omeprazole C. Tranexamic acid D. Octreotide E. Ceftriaxone Answer: C - The HALT-IT trial (2020, n=12,009) demonstrated that tranexamic acid does NOT reduce mortality in GI bleeding and may increase venous thromboembolism risk.
Question 5: A patient with an INR of 6.5 on warfarin presents with haematemesis and a BP of 85/50. PCC is administered. What is the target INR for reversal in life-threatening bleeding? A. <3.0 B. <2.5 C. <2.0 D. <1.5 E. <1.0 Answer: D - Target INR <1.5 for life-threatening bleeding. PCC (prothrombin complex concentrate) 25-50 units/kg is preferred over FFP as it provides rapid, complete reversal.

Pathology and Radiology Interpretation
Endoscopic Appearances:
| Finding | Description | Clinical Significance |
|---|---|---|
| Spurting vessel | Pulsatile arterial bleeding | Forrest Ia - 90% rebleed - requires immediate therapy |
| Oozing | Non-pulsatile bleeding | Forrest Ib - requires therapy |
| Visible vessel | Pigmented protuberance in ulcer base | Forrest IIa - 50% rebleed - requires therapy |
| Adherent clot | Blood clot covering ulcer | Forrest IIb - consider clot removal and therapy |
| Flat pigmented spot | Flat discolouration | Forrest IIc - low risk - medical therapy |
| Clean base | White/grey ulcer base | Forrest III - <5% rebleed - discharge consideration |
Variceal Grading:
- Grade I: Small, straight varices
- Grade II: Moderate, tortuous varices occupying <1/3 oesophageal lumen
- Grade III: Large, coil-shaped varices occupying >1/3 lumen
- Blue colour: Higher rupture risk
- Red signs (red wale marks, cherry red spots): Imminent bleeding risk
CT Findings in UGIB:
- Active extravasation: Hyperdense contrast within stomach/duodenal lumen
- Arterial phase blush: Active bleeding visible on CT angiography
- Pseudoaneurysm: Focal outpouching from vessel, high rebleed risk
- Varices: Enlarged tortuous vessels in portal distribution
- Portal hypertension signs: Splenomegaly, ascites, collaterals
Angiographic Findings:
- Active bleeding: Contrast extravasation (requires >0.5mL/min bleeding)
- Pseudoaneurysm: Focal contrast outpouching
- Abnormal vessels: Dieulafoy lesion shows large calibre submucosal vessel
- Embolisation targets: Gastroduodenal artery (DU), left gastric artery (varices/GU)

Australian/New Zealand Guidelines:
- GESA (Gastroenterological Society of Australia) guidelines align with international practice
- Emphasis on rural/remote considerations for transfer
- Telehealth consultation for endoscopy decision-making
European Variations:
- ESGE guidelines form basis of European practice
- Some variation in vasoactive drug choice (terlipressin vs somatostatin)
- Similar emphasis on restrictive transfusion
Historical Perspective
Key Milestones:
- 1958: First fibreoptic endoscope developed (Hirschowitz)
- 1974: Therapeutic endoscopy for UGIB introduced
- 1983: H. pylori discovered (Marshall and Warren - Nobel Prize 2005)
- 1990s: Forrest classification widely adopted
- 1996: Glasgow-Blatchford Score developed
- 2000: Rockall score refined for post-endoscopy risk
- 2010: IV PPI regimens standardised (Sung et al)
- 2013: Restrictive transfusion strategy shown superior (Villanueva)
- 2020: HALT-IT trial disproves tranexamic acid benefit
Evolution of Management:
- Historical: Surgery was primary treatment for bleeding ulcers
- 1980s-90s: Endoscopic therapy became first-line
- 2000s: PPI revolutionised acid suppression
- 2010s: Focus on transfusion targets and timing
- Present: Multidisciplinary approach, protocol-driven care
