Managing Esophageal Varices in Portal Hypertension

Esophageal varices are enlarged veins that develop when portal hypertension diverts blood through fragile vessels in the oesophagus. They may cause no symptoms until they rupture, when bleeding can become life-threatening within minutes. Portal hypertension commonly results from cirrhosis related to alcohol-associated liver disease, viral hepatitis, metabolic dysfunction-associated steatotic liver disease or autoimmune liver conditions.

Management combines prevention, rapid treatment of acute haemorrhage and control of the underlying liver disease. In Australia, care may involve a general practitioner, emergency team, gastroenterologist, hepatologist, endoscopy service and, for advanced disease, a liver transplant unit. Treatment should follow local hospital protocols and specialist advice.

Recognising Risk And Confirming The Cause

Patients with newly diagnosed cirrhosis or clinically significant portal hypertension should be assessed for varices. Upper gastrointestinal endoscopy is used when indicated, while non-invasive liver assessment, platelet count, spleen size and imaging can help estimate risk. Transient elastography, commonly available through Australian liver clinics, may support assessment but does not replace clinical judgement.

Risk rises with large varices, red wale markings, severe liver dysfunction and previous variceal bleeding. A person with vomiting blood, black stools, dizziness, fainting, confusion or cold clammy skin needs emergency care. In Australia, family members should call triple zero (000), particularly when travelling from rural or remote areas where retrieval time can be substantial.

Preventing A First Bleed

For patients with medium or large varices, primary prevention usually involves a non-selective beta blocker or endoscopic variceal ligation. Propranolol and carvedilol reduce portal venous pressure, while band ligation mechanically closes high-risk varices. The choice depends on blood pressure, kidney function, ascites, asthma, adherence and access to repeat endoscopy.

Carvedilol or propranolol must be introduced carefully and adjusted by a clinician. Excessive lowering of blood pressure, acute kidney injury, infection or refractory ascites may require treatment to be paused or changed. If beta blockers are unsuitable, planned band ligation is generally repeated at intervals until the varices are eradicated.

Reducing alcohol intake or stopping altogether, treating hepatitis B or C, managing metabolic risk factors and avoiding medicines that increase bleeding or kidney risk are important. Non-steroidal anti-inflammatory drugs such as ibuprofen should generally be avoided unless a treating doctor specifically approves them.

Responding To Acute Variceal Haemorrhage

Acute bleeding requires resuscitation, airway assessment and urgent specialist management. Large-bore intravenous access, blood tests, crossmatching and correction of dangerous circulatory compromise are priorities. A restrictive red-cell transfusion strategy is commonly used, with a target haemoglobin around 70–80 g/L unless the patient has a specific reason for a different approach.

A vasoactive medicine, usually terlipressin or an appropriate alternative, should be started as soon as variceal bleeding is suspected. Short-course antibiotic prophylaxis, often ceftriaxone according to local policy, lowers the risk of infection and recurrent haemorrhage. Antibiotic selection must account for allergy, resistance patterns and the patient’s clinical setting.

Endoscopy should usually occur within 12 hours after initial stabilisation. Endoscopic band ligation is the preferred treatment for oesophageal varices. If bleeding cannot be controlled, a covered oesophageal stent or balloon tamponade may provide temporary control while the patient is transferred for transjugular intrahepatic portosystemic shunt (TIPS) assessment.

Preventing Rebleeding And Further Decompensation

After a first variceal bleed, combined treatment with a non-selective beta blocker and repeated band ligation is standard secondary prevention. Endoscopy is repeated until varices are eradicated, with follow-up surveillance because they can recur. Medication doses should be reviewed after infections, low blood pressure, kidney problems or changes in ascites.

Recurrent bleeding despite combined therapy is an indication for specialist review and often TIPS. Early TIPS may be considered for selected patients at high risk of treatment failure, based on liver function, bleeding severity and other clinical features. Encephalopathy, heart failure and severe liver failure can affect suitability.

The underlying liver disease needs active treatment. Patients with decompensated cirrhosis, repeated admissions, jaundice, ascites, encephalopathy or declining renal function should be referred to a hepatology or transplant service. In Australia, pathways differ between metropolitan hospitals and regional services, so shared care and clear retrieval plans are particularly important.

Choosing The Right Approach In Practice

Treatment decisions should be individualised rather than based on variceal size alone. A stable patient with high-risk varices may be managed electively, whereas active haemorrhage demands coordinated emergency, endoscopy and intensive-care support.

Australian patients may encounter different access arrangements: a city hospital may provide same-day endoscopy, while someone in the Northern Territory, regional Queensland or rural Western Australia may first need aeromedical retrieval. Medicare-funded consultations and public hospital pathways can support care, but private endoscopy and specialist waiting times vary between states and services. Aboriginal and Torres Strait Islander patients may also benefit from culturally safe care, interpreters where needed and coordinated management of hepatitis, alcohol-related liver disease and other causes of cirrhosis.

The practical takeaway is simple: treat suspected variceal bleeding as an emergency, start hospital-based vasoactive and antibiotic therapy promptly, arrange early endoscopic band ligation, and maintain long-term specialist follow-up to prevent recurrence.
