Gastroesophageal Varices: A Complete Patient Guide
Overview
Gastroesophageal varices (GEV) are enlarged, fragile veins that develop in the lining of the esophagus or the upper part of the stomach. They form as a direct consequence of increased pressure in the portal venous system (portal hypertension), most commonly secondary to liver cirrhosis. When these veins rupture, they can cause life‑threatening upper‑gastrointestinal bleeding.
- Who it affects: Adults with advanced liver disease, especially those with alcoholic or viral (HBV/HCV) cirrhosis. Rarely, children with congenital portal vein anomalies may develop varices.
- Prevalence: Up to 50 % of patients with compensated cirrhosis develop esophageal varices, and 30 % of those will experience a variceal bleed over a 2‑year period [1]. Worldwide, cirrhosis affects an estimated 1–2 % of the adult population, making GEV a common complication in hepatology clinics.
Symptoms
Many patients are asymptomatic until a bleed occurs. When symptoms appear, they may include:
- Upper‑GI bleeding: Hematemesis (vomiting fresh or coffee‑ground blood) or melena (black, tarry stools).
- Early satiety or dysphagia: Large varices can press against the esophagus, making swallowing uncomfortable.
- Chest or upper‑back discomfort: A feeling of pressure rather than true pain.
- Anemia‑related signs: Fatigue, dizziness, shortness of breath, or pale skin due to chronic blood loss.
- Signs of portal hypertension: Enlarged abdomen (ascites), splenomegaly, or caput medusae (visible abdominal veins).
- Weight loss: Often secondary to anorexia from discomfort or chronic illness.
Causes and Risk Factors
Gastroesophageal varices do not arise spontaneously; they are a downstream effect of portal hypertension. Key contributors include:
Primary Causes
- Cirrhosis: Alcoholic liver disease, chronic hepatitis B or C, non‑alcoholic steatohepatitis (NASH), autoimmune hepatitis.
- Portal vein thrombosis: Blood clot in the portal vein obstructs flow.
- Schistosomiasis: Particularly in endemic areas, this parasitic infection can cause presinusoidal portal hypertension.
- Congenital hepatic fibrosis or vascular malformations: Rare pediatric causes.
Risk Factors that Increase the Likelihood of Variceal Development or Bleeding
- Advanced liver disease (Child‑Pugh Class B or C).
- Presence of red wale marks or “cherry red spots” on endoscopic examination.
- Large variceal size (≥ 5 mm) on endoscopy.
- Previous episodes of variceal bleeding.
- Alcohol use > 30 g/day for men / > 20 g/day for women.
- Coagulopathy (INR > 1.5) and thrombocytopenia (< 50 × 10⁹/L).
Diagnosis
Timely identification of gastroesophageal varices is essential to prevent catastrophic bleeding.
Screening Recommendations
- All patients with compensated cirrhosis should undergo an upper endoscopy (esophagogastroduodenoscopy, EGD) at diagnosis, and then every 2–3 years if no varices are found [2].
- Patients with known varices should have repeat endoscopy every 6–12 months depending on size and treatment status.
Diagnostic Tools
- Upper Endoscopy (EGD): Gold standard; visualizes variceal size, location, and stigmata of recent hemorrhage.
- Transient Elastography (FibroScan): Non‑invasive measurement of liver stiffness; higher stiffness correlates with portal hypertension.
- Doppler Ultrasound: Assesses portal vein flow direction and speed, helps identify portal vein thrombosis.
- CT or MRI Portography: Detailed anatomy for pre‑procedure planning, especially before transjugular intrahepatic portosystemic shunt (TIPS).
- Laboratory Tests: Complete blood count, liver panel, coagulation profile, and viral serologies to stage liver disease.
Treatment Options
Treatment aims to prevent first‑time bleeding (primary prophylaxis), stop active hemorrhage, and prevent re‑bleeding (secondary prophylaxis).
Primary Prophylaxis (preventing the first bleed)
- Non‑selective β‑blockers (NSBB): Propranolol (20–80 mg BID) or carvedilol (6.25 mg BID) reduce portal pressure. Target heart rate 55–60 bpm.[3]
- Endoscopic Variceal Ligation (EVL): Banding of medium‑to‑large varices, usually every 2–4 weeks until eradication.
- Combination therapy (NSBB + EVL) is often recommended for high‑risk patients.
Management of Active Bleeding
- Resuscitation: Secure airway, give oxygen, and perform controlled fluid replacement (maintain systolic BP 90–100 mm Hg). Transfuse packed RBCs to keep hemoglobin 7–8 g/dL.
- Pharmacologic therapy: IV octreotide (50 µg bolus, then 50 µg/h infusion) or terlipressin (2 mg IV every 4 h) to reduce portal pressure.
- Endoscopic therapy: Urgent EVL (within 12 h) or sclerotherapy if ligation is not feasible.
- Rescue procedures: If bleeding persists, consider balloon tamponade (Sengstaken-Blakemore tube) or early TIPS placement.
Secondary Prophylaxis (preventing re‑bleeding)
- Combination of NSBB plus EVL is the standard of care.
- For patients who fail medical/endoscopic therapy, a Transjugular Intrahepatic Portosystemic Shunt (TIPS) creates a low‑resistance channel between portal and hepatic veins, lowering portal pressure.
- In selected cases, surgical shunts (e.g., distal splenorenal shunt) may be considered, especially when liver transplantation is planned.
Lifestyle and Supportive Measures
- Complete abstinence from alcohol.
- Weight management and control of metabolic risk factors (diabetes, hyperlipidemia) to slow progression of NASH.
- Vaccinations (HAV, HBV, pneumococcus, influenza) to prevent superimposed infections.
- Regular monitoring of liver function and portal pressure.
Living with Gastroesophageal Varices
Adapting daily life can reduce anxiety and improve outcomes.
- Medication adherence: Set alarms for beta‑blocker dosing; never skip doses without consulting your provider.
- Dietary tips: Small, frequent meals; avoid large meals that increase portal flow. Limit salt (< 2 g/day) to control ascites.
- Alcohol avoidance: Seek counseling or support groups; even moderate drinking can worsen portal hypertension.
- Regular follow‑up: Keep scheduled endoscopies and liver clinic visits.
- Travel precautions: Carry a copy of your medical summary, list of medications, and a letter describing the need for urgent care if bleeding occurs.
- Emergency plan: Know the nearest hospital with an interventional endoscopy service; inform family members of the signs that require immediate help.
Prevention
Because varices are a downstream effect of liver disease, preventing liver injury is the most effective strategy.
- Limit alcohol intake: No more than 1 drink/day for women, 2 drinks/day for men; ideally none if you have cirrhosis.
- Vaccinate against hepatitis B and practice safe sex/injection practices to avoid hepatitis C.
- Maintain a healthy weight: Aim for BMI < 25 kg/m²; diet rich in fruits, vegetables, whole grains, and lean protein.
- Control metabolic syndrome: Manage blood pressure, glucose, and lipids.
- Avoid hepatotoxic medications: High‑dose acetaminophen, certain herbal supplements, and illicit drugs.
- Screen at‑risk populations: Annual ultrasound with alpha‑fetoprotein for patients with chronic hepatitis B or C.
Complications
If gastroesophageal varices are not adequately treated, serious complications can arise:
- Massive upper‑GI hemorrhage: Leading cause of hospital admission for cirrhotic patients; mortality can exceed 20 % despite treatment.
- Re‑bleeding: Occurs in 60 % of patients within 1 year if secondary prophylaxis is not instituted.
- Infection: Spontaneous bacterial peritonitis (SBP) is more common after a bleed due to bacterial translocation.
- Hepatic encephalopathy: Particularly after TIPS, as shunting bypasses the liver’s detoxifying function.
- Development of portal vein thrombosis: Can further raise portal pressure.
- Reduced quality of life: Chronic fatigue, anxiety about bleeding, and dietary restrictions.
When to Seek Emergency Care
- Vomiting bright red blood or material that looks like coffee grounds.
- Black, tarry stools or streaks of blood in the stool.
- Sudden, severe weakness, dizziness, or fainting.
- Rapid heart rate (≥ 120 bpm) or a drop in blood pressure (systolic < 90 mm Hg).
- Severe chest or upper‑abdominal pain accompanied by vomiting.
