What is the best course of management for a teenage male with acute upper GI bleeding due to high-grade esophageal and gastric varices, likely caused by underlying portal hypertension?

Comprehensive Clinical Analysis: Adolescent with Acute Variceal Bleeding and Portal Hypertension

1. Presentation and Investigations: Real-Time Clinical Processing

Initial Red Flags and Severity Markers

This adolescent presents with life-threatening upper GI bleeding requiring immediate recognition of critical features:

• Hemodynamic compromise: BP 90/62 mmHg with persistent low diastolic pressures (53-54 mmHg) indicates significant volume depletion and ongoing vascular instability 1
• Severe anemia requiring 2-unit transfusion before arrival signals substantial blood loss 1
• Hypoxemia (SpO2 90%) suggests either aspiration risk, volume overload, or hepatopulmonary syndrome 1
• High-risk variceal features: Large, tortuous esophageal varices with red signs plus gastric fundal varices represent the highest bleeding risk category 2

Age-Specific Epidemiologic Clues

Portal hypertension in a 15-16 year old male is NOT cirrhosis until proven otherwise 3. The differential dramatically shifts in adolescents:

• Extrahepatic portal vein obstruction (EHPVO) is the most common cause of portal hypertension in children and adolescents, typically presenting with acute variceal bleeding as the sentinel event 3
• Normal liver enzymes (transaminases, alkaline phosphatase, GGT) are pathognomonic for non-cirrhotic portal hypertension and essentially rule out cirrhotic liver disease 3
• Absence of stigmata of chronic liver disease: No jaundice, no encephalopathy, no significant ascites (only moderate), alert and oriented—all point away from cirrhosis 3
• Splenomegaly with suspected hypersplenism is characteristic of chronic portal hypertension from venous obstruction rather than hepatocellular dysfunction 3

Critical Missing Data

The ultrasound report is incomplete and inadequate 3. What we desperately need:

• Portal vein patency assessment: Is the main portal vein patent or thrombosed? Is there cavernomatous transformation (porto-portal collaterals)? 3
• Splenic vein patency: Isolated splenic vein thrombosis causes left-sided portal hypertension with gastric varices 3, 4
• Hepatic vein patency: Budd-Chiari syndrome must be excluded 3

Laboratory Interpretation

• Anemia: Expected from acute hemorrhage, requiring restrictive transfusion strategy targeting Hb 7-9 g/dL 3
• Possible infection/inflammation: Could represent spontaneous bacterial peritonitis (though ascites is only moderate) or post-bleeding inflammatory response 3
• Normal liver enzymes: This is the single most important lab finding—it excludes cirrhosis and points to EHPVO or other non-cirrhotic causes 3

Endoscopic Findings Integration

The endoscopy reveals a catastrophic variceal pattern:

• Large esophageal varices with red signs indicate imminent or recent rupture 2
• Gastric fundal varices (GOV2 pattern) are particularly dangerous—they bleed less frequently but more massively than esophageal varices 1
• Isolated gastric varices may suggest splenic vein thrombosis if present 4

2. Problem List (Ordered by Urgency)

Problem #1: Acute Life-Threatening Upper GI Hemorrhage from High-Risk Varices

Why included: Active or recent variceal bleeding with hemodynamic instability (BP 90/62, requiring transfusion) 2

Links to other problems: Direct consequence of portal hypertension; drives risk of hypovolemic shock, aspiration, hepatic decompensation 2

Problem #2: Severe Portal Hypertension of Unknown Etiology

Why included: Massive varices with splenomegaly and ascites indicate clinically significant portal hypertension 3

Links to other problems: Root cause of variceal bleeding; determines long-term management strategy; age-appropriate differential is critical 3

Problem #3: Persistent Hemodynamic Instability

Why included: Ongoing low diastolic BP (53-54 mmHg) despite resuscitation suggests inadequate volume replacement or continued bleeding 1

Links to other problems: Increases rebleeding risk; may indicate need for salvage therapy; affects timing of further interventions 1

Problem #4: Hypoxemia (SpO2 90-95%)

Why included: Persistent hypoxemia may indicate aspiration, pulmonary edema from over-resuscitation, or hepatopulmonary syndrome 1

Links to other problems: Complicates sedation for procedures; may worsen with beta-blockers; requires investigation 1

Problem #5: Possible Infection/Inflammation

Why included: Lab findings suggest infection; bacterial infection dramatically increases mortality in variceal bleeding 3

Links to other problems: Increases rebleeding risk; may indicate spontaneous bacterial peritonitis; requires antibiotic coverage 3

Problem #6: Splenomegaly with Suspected Hypersplenism

Why included: Massive splenomegaly indicates chronic portal hypertension; hypersplenism may cause thrombocytopenia increasing bleeding risk 3

Links to other problems: Supports EHPVO diagnosis; may require specific interventions; affects coagulation 3

3. Interpretation & Clinical Reasoning: Pathophysiologic Integration

The Pathophysiologic Chain

In this adolescent, the most likely sequence is:

1. Portal vein thrombosis (likely in infancy or early childhood from umbilical vein catheterization, neonatal sepsis, or inherited thrombophilia) 3
2. Cavernomatous transformation develops as porto-portal collaterals attempt to bypass the occluded portal vein 3
3. Chronic portal hypertension leads to splenomegaly, hypersplenism, and development of portosystemic collaterals (varices) 3
4. Variceal rupture occurs when wall tension exceeds vessel strength, triggered by increased portal pressure 2

Why This Pattern is Alarming in an Adolescent

This presentation is concerning for several reasons:

• EHPVO typically presents earlier in childhood; presentation at 15-16 years suggests either late diagnosis or recent thrombotic event 3
• Combined esophageal and gastric varices indicate extensive collateral formation and severe portal hypertension 1
• Normal liver function means this patient has normal hepatic reserve but faces lifelong bleeding risk without definitive treatment 3
• Prothrombotic workup is mandatory: Personal or family history of unprovoked DVT, inherited thrombophilias must be investigated 3

Integrated Interpretation: Labs + Ultrasound + Endoscopy

The clinical picture crystallizes:

• Normal liver enzymes + massive varices + splenomegaly = EHPVO until proven otherwise 3
• Moderate ascites in EHPVO suggests either severe portal hypertension or hypoalbuminemia from chronic disease 3
• Ultrasound showing splenomegaly is consistent but inadequate—we need portal vein imaging 3
• High-risk endoscopic features mandate aggressive secondary prophylaxis 2

4. Differential Diagnosis: Focused Analysis

Most Likely: Extrahepatic Portal Vein Obstruction (EHPVO)

Why considered:

• Age 15-16 years with acute variceal bleeding as presenting symptom 3
• Normal liver enzymes (transaminases, alkaline phosphatase, GGT) 3
• Splenomegaly with suspected hypersplenism 3
• No stigmata of chronic liver disease 3

Supporting evidence: EHPVO is the most common cause of portal hypertension in children and adolescents, typically presenting with acute variceal bleeding 3

Why NOT ruled out: Ultrasound did not adequately assess portal vein patency or cavernomatous transformation 3

Second Most Likely: Splenic Vein Thrombosis (Left-Sided Portal Hypertension)

Why considered:

• Gastric fundal varices are prominent 4
• Splenomegaly is present 4
• Can occur in adolescents from pancreatitis, trauma, or hypercoagulable states 4

Why less likely:

• Esophageal varices are also present and severe; splenic vein thrombosis typically causes isolated gastric varices 4
• No history of pancreatitis or abdominal trauma 4

How to rule out: CT or MRI with portal venous phase contrast to assess splenic vein patency 3, 4

Third: Non-Cirrhotic Portal Fibrosis (Idiopathic Portal Hypertension)

Why considered:

• Can present in adolescents 3
• Normal liver enzymes 3
• Portal hypertension with preserved liver function 3

Why less likely:

• More common in adults 3
• Usually diagnosed after excluding EHPVO and other causes 3

How to rule out: Liver biopsy showing portal fibrosis without cirrhosis, after vascular causes excluded 3

Fourth: Budd-Chiari Syndrome

Why considered:

• Can cause portal hypertension in young patients 3
• Associated with hypercoagulable states 3
• Ascites is present 3

Why less likely:

• Typically presents with acute hepatic decompensation, abdominal pain, and elevated liver enzymes 3
• This patient has normal liver enzymes and no abdominal pain 3

How to rule out: Imaging showing hepatic vein patency 3

Fifth: Congenital Hepatic Fibrosis

Why considered:

• Can present in adolescence 3
• Causes non-cirrhotic portal hypertension 3

Why less likely:

• Usually associated with renal abnormalities (polycystic kidney disease) 3
• No mention of renal findings 3

How to rule out: Renal ultrasound, liver biopsy 3

Essentially Ruled Out: Cirrhosis from Any Cause

Why initially considered: Portal hypertension with varices

Why ruled out:

• Normal liver enzymes exclude active hepatocellular injury 3
• No stigmata of chronic liver disease: No jaundice, no encephalopathy, alert and oriented 3
• Age 15-16 years: Cirrhosis severe enough to cause this degree of portal hypertension would require years of liver disease 3
• Absence of risk factors: No mention of hepatitis, alcohol use, metabolic disease 3

5. Final Working Diagnosis

This is a 15-16 year old male with acute variceal hemorrhage secondary to severe non-cirrhotic portal hypertension, most likely from extrahepatic portal vein obstruction (EHPVO) with cavernomatous transformation.

Justification:

Clinical reasoning:

• The combination of massive variceal bleeding, normal liver enzymes, splenomegaly, and absence of chronic liver disease stigmata in an adolescent is pathognomonic for EHPVO 3
• EHPVO typically presents with acute variceal bleeding as the sentinel event in children and adolescents 3
• The severity of portal hypertension (large varices, splenomegaly, ascites) contrasts sharply with normal hepatic function 3

Endoscopic reasoning:

• High-risk esophageal varices with red signs plus gastric varices indicate severe portal hypertension 2
• This pattern is consistent with chronic portal vein obstruction with extensive collateral formation 3

Epidemiologic reasoning:

• EHPVO is the most common cause of portal hypertension in the pediatric and adolescent population 3
• Cirrhosis is extremely rare in this age group without known predisposing conditions 3

Definitive diagnosis requires: CT or MRI with portal venous phase contrast showing portal vein thrombosis/cavernomatous transformation 3

6. Current Management: Evidence-Based Critique

Blood Transfusion (2 units initially, ongoing resuscitation)

What was done: Patient received 2-unit transfusion at referring facility, with ongoing fluid resuscitation

Appropriateness: Partially appropriate but requires modification 1, 3

Evidence-based rationale:

• Restrictive transfusion strategy is superior: Target Hb 7-9 g/dL, not higher 3
• Over-transfusion increases portal pressure, impairs clot formation, and increases rebleeding risk 1
• The persistent low diastolic BP (53-54 mmHg) suggests either inadequate resuscitation OR over-resuscitation with fluid overload 1
• Target mean arterial pressure >65 mmHg while avoiding fluid overload 1

Recommendation: Check current Hb; if >7 g/dL and hemodynamically stable, hold further transfusion 3

Endoscopic Variceal Ligation (EVL) and Glue Injection

What was done: Combined EVL for esophageal varices and cyanoacrylate glue injection for gastric varices

Appropriateness: Highly appropriate and evidence-based 1, 2, 5

Evidence-based rationale:

• EVL is the endoscopic treatment of choice for esophageal varices, achieving 85-90% initial hemostasis 1, 2
• Cyanoacrylate injection is the treatment of choice for gastric varices, particularly GOV2 and isolated gastric varices 1, 5
• Combination therapy addresses both variceal types in this patient with mixed esophageal and gastric varices 1
• Endoscopy should be performed within 12 hours after resuscitation in stable patients 2

Caveat: Cyanoacrylate is not FDA-approved in the United States and should only be used in centers with expertise 6

Omeprazole

What was done: Proton pump inhibitor prescribed

Appropriateness: Appropriate as adjunctive therapy 2

Evidence-based rationale:

• PPIs reduce gastric acidity, which may help stabilize clots at variceal ligation sites 2
• Standard practice in upper GI bleeding management 2
• Not the primary therapy for variceal bleeding but provides supportive benefit 2

Ceftriaxone

What was done: Antibiotic prophylaxis initiated

Appropriateness: Highly appropriate and evidence-based 3, 6

Evidence-based rationale:

• Antibiotic prophylaxis reduces mortality, bacterial infections, and rebleeding in variceal hemorrhage 3, 6
• Ceftriaxone 1 g IV every 24 hours is the recommended regimen 6
• Should be started immediately upon admission 3
• Maximum duration 7 days to avoid resistance 6

Recommendation: Confirm dose is 1 g/24h and plan to discontinue after 7 days 6

Propranolol

What was done: Non-selective beta-blocker initiated

Appropriateness: Appropriate for secondary prophylaxis but requires careful titration and monitoring 3, 6

Evidence-based rationale:

• Non-selective beta-blockers (NSBBs) are first-line for secondary prophylaxis after variceal bleeding 3, 6
• However, carvedilol 12.5 mg/day is superior to propranolol, achieving hemodynamic response in 75% vs 46-50% 6
• Target resting heart rate 55-60 bpm to achieve portal pressure reduction >20% or to <12 mmHg 3, 6
• Critical caveat: NSBBs should be temporarily suspended during acute bleeding with hypotension (SBP <90 mmHg or MAP <65 mmHg) 6

Concerns in this patient:

• Persistent low diastolic BP (53-54 mmHg) raises concern about beta-blocker tolerance 6
• Hypoxemia (SpO2 90-95%) may worsen with beta-blockers due to bronchospasm 6
• Should have been started AFTER hemodynamic stabilization, not during acute phase 6

Recommendation:

• Hold propranolol until MAP consistently >65 mmHg and SBP >90 mmHg 6
• Consider switching to carvedilol 12.5 mg/day once stable 6
• Titrate to target HR 55-60 bpm 3, 6

Vasoactive Drug Therapy (Not Mentioned—Critical Omission)

What was NOT done: No mention of vasoactive drugs (terlipressin, octreotide, somatostatin)

Appropriateness: Critical omission—vasoactive drugs should have been started immediately 1, 3, 6, 2

Evidence-based rationale:

• Vasoactive drugs should be started as soon as variceal bleeding is suspected, BEFORE endoscopy 1, 3, 6, 2
• Terlipressin is most effective: 0.5-1.0 mg IV every 4-6 hours, increased to 2 mg every 4-6 hours if needed 6
• Octreotide is alternative: 50 mcg bolus followed by 50 mcg/hour infusion 1, 2
• Combination of vasoactive drugs + endoscopy is superior to endoscopy alone, improving 5-day hemostasis from 58% to 77% 1
• Should be continued for 2-5 days after bleeding control 1, 2

Recommendation: If not already given, start vasoactive therapy immediately and continue for 2-5 days 1, 3, 6, 2

7. Additional Recommendations: Comprehensive Management Plan

Immediate (Within 24 Hours)

1. Obtain Definitive Vascular Imaging

What: CT abdomen/pelvis with IV contrast in portal venous phase, or MRI with MR portography 3

Why:

• Confirm portal vein patency vs thrombosis/cavernomatous transformation to establish EHPVO diagnosis 3
• Assess splenic vein patency to rule out isolated splenic vein thrombosis 3, 4
• Evaluate hepatic vein patency to exclude Budd-Chiari syndrome 3
• Identify portosystemic shunts that may influence management 6

How it benefits this patient: Establishes definitive diagnosis, guides long-term management, identifies need for anticoagulation 3

2. Initiate or Continue Vasoactive Drug Therapy

What: Terlipressin 1 mg IV every 4-6 hours (if available) or octreotide 50 mcg bolus then 50 mcg/hour infusion 1, 3, 6, 2

Why:

• Reduces splanchnic blood flow and portal pressure 6
• Improves hemostasis and reduces rebleeding when combined with endoscopy 1
• Should be continued for 2-5 days after bleeding control 1, 2

How it benefits this patient: Reduces rebleeding risk during critical first 5 days when risk is highest 1, 2

3. Reassess Hemodynamic Status and Transfusion Strategy

What:

• Check current Hb; target 7-9 g/dL 3
• Assess volume status; avoid over-resuscitation 1
• Monitor MAP; target >65 mmHg 1, 6

Why:

• Restrictive transfusion strategy (Hb 7-9 g/dL) reduces mortality and rebleeding 3
• Over-resuscitation increases portal pressure and rebleeding risk 1
• Persistent low diastolic BP may indicate inadequate resuscitation or continued bleeding 1

How it benefits this patient: Optimizes hemodynamics while minimizing rebleeding risk 1, 3

4. Investigate Hypoxemia

What:

• Chest X-ray to assess for aspiration, pulmonary edema 1
• Arterial blood gas if SpO2 remains <92% 1
• Consider echocardiography if hepatopulmonary syndrome suspected 1

Why:

• Persistent hypoxemia (SpO2 90-95%) requires investigation 1
• May indicate aspiration during bleeding episode 1
• May represent pulmonary edema from over-resuscitation 1
• Hepatopulmonary syndrome can occur in portal hypertension 1

How it benefits this patient: Identifies treatable causes of hypoxemia; affects beta-blocker tolerance 1, 6

Short-Term (Within 1 Week)

5. Comprehensive Prothrombotic Workup

What:

• Personal and family history of unprovoked DVT or thrombosis 3
• Inherited thrombophilia panel: Factor V Leiden, prothrombin G20210A, protein C/S deficiency, antithrombin deficiency 3
• Acquired thrombophilia: Antiphospholipid antibodies, JAK2 mutation (myeloproliferative disorders) 3

Why:

• EHPVO in adolescents often has underlying prothrombotic condition 3
• Identifies need for long-term anticoagulation 3
• Affects family counseling and screening 3

How it benefits this patient: Guides anticoagulation decisions; prevents recurrent thrombosis; informs family screening 3

6. Assess for Spontaneous Bacterial Peritonitis

What: Diagnostic paracentesis with cell count, culture, albumin 3

Why:

• Moderate ascites is present 3
• Lab findings suggest possible infection/inflammation 3
• SBP dramatically increases mortality in variceal bleeding 3

How it benefits this patient: Identifies need for prolonged antibiotic therapy; affects prognosis 3

7. Optimize Beta-Blocker Therapy

What:

• Hold propranolol until hemodynamically stable (MAP >65 mmHg, SBP >90 mmHg consistently) 6
• Consider switching to carvedilol 12.5 mg/day 6
• Titrate to target HR 55-60 bpm 3, 6
• Monitor for hypotension, bronchospasm 6

Why:

• Carvedilol is superior to propranolol for portal pressure reduction 6
• Target HR 55-60 bpm achieves optimal portal pressure reduction 3, 6
• NSBBs must be used cautiously with hypotension or hypoxemia 6

How it benefits this patient: Maximizes secondary prophylaxis efficacy while minimizing adverse effects 3, 6

8. Plan Repeat Endoscopic Variceal Ligation

What: Repeat EVL every 2-8 weeks until variceal eradication 3

Why:

• Combination of NSBB + repeat EVL is standard for secondary prophylaxis 3
• Repeat EVL every 2-8 weeks until eradication 3
• Surveillance endoscopy 1-6 months after eradication, then every 6-12 months 3

How it benefits this patient: Reduces rebleeding risk; achieves variceal eradication 3

Medium-Term (Within 1 Month)

9. Hepatology/Pediatric Gastroenterology Referral

What: Referral to tertiary center with expertise in pediatric/adolescent portal hypertension 3, 6

Why:

• EHPVO in adolescents requires specialized expertise 3
• Long-term management decisions require multidisciplinary input 6
• May need interventional radiology consultation for TIPS or other procedures 1, 6

How it benefits this patient: Ensures optimal long-term management; access to advanced therapies 3, 6

10. Assess for Portal Cholangiopathy

What:

• Liver function tests (bilirubin, alkaline phosphatase, GGT) 3
• If abnormal, MRCP to assess biliary tree 3

Why:

• Portal cholangiopathy occurs in 80-100% of EHPVO patients 3
• Cavernomatous transformation compresses bile ducts 3
• Can cause cholangitis, biliary strictures 3

How it benefits this patient: Identifies biliary complications requiring intervention 3

11. Consider Anticoagulation

What:

• Once acute bleeding controlled and hemodynamically stable 3
• If prothrombotic condition identified 3
• Low-molecular-weight heparin or warfarin 3

Why:

• Anticoagulation should be strongly considered in EHPVO after acute bleeding controlled 3
• May promote portal vein recanalization 3
• Prevents recurrent thrombosis 3

How it benefits this patient: Prevents progression of thrombosis; may improve portal hemodynamics 3

Critical caveat: Avoid anticoagulation with active bleeding, severe thrombocytopenia, or high rebleeding risk 6

Long-Term (Within 3-6 Months)

12. Reassess Portal Vein Recanalization

What: Repeat CT or MRI at 6-12 months to assess recanalization status 3

Why:

• Recanalization may occur with anticoagulation 3
• Affects long-term anticoagulation decisions 3

How it benefits this patient: Guides duration of anticoagulation; assesses treatment response 3

13. Consider TIPS or Surgical Shunt if Refractory Bleeding

What:

• TIPS ± embolization if rebleeding despite optimal medical and endoscopic therapy 1, 6
• Meso-Rex shunt (mesenteric-to-left portal vein bypass) may be option in EHPVO with suitable anatomy 3

Why:

• TIPS is recommended for refractory variceal bleeding despite endoscopic and drug therapy 1
• In EHPVO, Meso-Rex shunt can restore physiologic portal flow 3
• Salvage TIPS not recommended if Child-Pugh >13 (not applicable in this non-cirrhotic patient) 1

How it benefits this patient: Provides definitive portal decompression if medical/endoscopic therapy fails 1, 3, 6

When to consider:

• Rebleeding despite VBL + NSBB 1
• Large or multiple gastric varices 1
• Severe complications of portal hypertension 1

14. Screen for Hepatocellular Carcinoma (If Cirrhosis Develops)

What: Ultrasound ± AFP every 6 months 2

Why:

• Not indicated in EHPVO without cirrhosis 3
• Only relevant if cirrhosis develops 2

How it benefits this patient: Not applicable unless cirrhosis develops 3, 2

15. Liver Transplant Evaluation (If Indicated)

What: Referral to transplant center if severe complications develop 1

Why:

• Not typically needed in EHPVO with preserved liver function 3
• May be considered if severe portal cholangiopathy, recurrent bleeding, or liver dysfunction develops 3

How it benefits this patient: Provides definitive cure if complications become life-limiting 3

8. Learning Points: Ward-Relevant Pearls

Diagnostic Pearls

• Normal liver enzymes + massive varices in an adolescent = EHPVO until proven otherwise—this is the single most important diagnostic clue 3

• Portal hypertension in children/adolescents is NOT cirrhosis—the differential is completely different from adults, with EHPVO being most common 3

• Ultrasound alone is inadequate for diagnosing EHPVO—you MUST have CT or MRI with portal venous phase contrast to assess portal vein patency and cavernomatous transformation 3

• Gastric varices are more dangerous than esophageal varices—they bleed less frequently but more massively, and require different treatment (cyanoacrylate, not banding) 1, 5

Management Pearls

• Vasoactive drugs BEFORE endoscopy—start terlipressin or octreotide as soon as variceal bleeding is suspected, don't wait for endoscopy 1, 3, 6, 2

• Restrictive transfusion saves lives—target Hb 7-9 g/dL, not higher; over-transfusion increases portal pressure and rebleeding risk 3

• Antibiotics are not optional—ceftriaxone 1 g/24h for up to 7 days reduces mortality, infections, and rebleeding 3, 6

• Carvedilol beats propranolol—75% hemodynamic response vs 46-50%, making carvedilol the preferred NSBB 6

• Beta-blockers can kill during acute bleeding—hold NSBBs if SBP <90 mmHg or MAP <65 mmHg during active bleeding 6

Prognostic Pearls

• EHPVO has excellent long-term prognosis IF bleeding is controlled—unlike cirrhosis, liver function is preserved, so focus is on preventing rebleeding 3

• Rebleeding risk is highest in first 5 days—this is when vasoactive drugs, antibiotics, and close monitoring are critical 1, 2

• Secondary prophylaxis is lifelong—NSBB + repeat EVL until eradication, then surveillance endoscopy every 6-12 months 3

Pitfall Avoidance

• Don't assume cirrhosis in young patients—age-appropriate differential diagnosis is essential 3

• Don't over-resuscitate—fluid overload increases portal pressure and rebleeding risk; target MAP >65 mmHg but avoid excess 1

• Don't forget prothrombotic workup—EHPVO in adolescents often has underlying hypercoagulable state requiring anticoagulation 3

• Don't treat gastric varices with banding—use cyanoacrylate injection or consider TIPS/embolization 1, 5

• Don't start beta-blockers during active bleeding with hypotension—wait until hemodynamically stable 6

• Don't forget to investigate the hypoxemia—persistent SpO2 90-95% requires explanation and may affect beta-blocker tolerance 1, 6
