What are Oesophageal Varices?
Oesophageal varices are extremely dilated sub-mucosal veins in the lower third of the oesophagus(passage from mouth to stomach). They are most often a consequence of portal hypertension, commonly due to Liver cirrhosis; Patients with Oesophageal varices have a strong tendency to develop bleeding.
Oesophageal varices are diagnosed with endoscopy. Oesophageal Varices resemble varicose veins, but they appear inside the oesophagus and occasionally they occur in the stomach.
Oesophageal Varices develop when the liver develops scar tissue, usually caused by liver cirrhosis (also see Liver Failure). Scar tissue in the liver increases the pressure in the liver and in the veins. The veins leading away from the liver, including the Oesophageal veins, have an increased pressure with the result of the vein walls getting thinner and therefore they are at risk of bursting with the result of a severe bleed. The veins in the oesophagus and in the stomach are the veins that are directly connected to the liver and are directly affected if the liver develops scar tissue.

Signs and Symptoms
Oesophageal varices usually don’t cause signs and symptoms unless they bleed. Signs and symptoms of bleeding Oesophageal varices include:
- Vomiting blood
- Black, tarry or bloody stools
- Shock, in severe cases
What Happens in Intensive Care?
- your loved one will require monitoring using a Bedside Monitors and an Arterial Catheter(Arterial Line)
- You can expect your loved one to have frequent Chest X-rays and blood tests(Blood& Pathology tests in Intensive Care) especially arterial blood gases (ABGs)
- Initially oxygen and respiratory support might be commenced via an oxygen mask or via Non- Invasive Ventilation(NIV) or BIPAP ventilation
- Full ventilation using a Ventilators(Breathing Machine) and a Breathing Tube (endotracheal tube) will usually be required to improve and maintain the oxygen delivery, especially if your loved one requires Balloon Tamponade Tubes
- Sedation may be used if your loved one is in an induced coma and requires mechanical Ventilation with Ventilators(Breathing Machine)
- Infusion pumps are administering drugs to support your loved ones blood pressure and haemodynamic system, as well as intravenous fluids may be administered via a central venous catheter/ CVC(Central Venous Lines)
- An NG Tube (Nasogastric Tubes) is usually inserted into your loved ones stomach, in order to commence nutrition or to remove fluids
- Urine Output is usually measured hourly, after insertion of a Urinary Catheter
- Medications such as terlipressin or vasopressin may be given to help reduce pressure in the liver.
- It is crucial to find the source of bleeding. This can be doen via Endoscopy(video camera) that can be inserted in the Oesophagus and the source of bleeding can be found. Drugs may be injected to cause the vessels to constrict and stop the bleeding
- If the bleeding is extremely severe, Balloon Tamponade Tubes(balloon tamponade device) may be inserted into the Oesophagus and stomach. Once the balloon is inserted, air pressure is inflated into the balloon in order to put pressure on the bleeding source(s) and stop the bleeding. The balloon tubes may stay in situ for 24-48 hours.
This is an example of a balloon tamponade tube
Further surgery may be needed to reduce portal hypertension. This procedure called transjugular intrahepatic portosystemic shunt (TIPPS). A metal opening device is placed in the liver connecting the hepatic and portal veins this allows blood to flow through a different path.
How long will your loved one remain in Intensive Care?
The time spent in Intensive Care will vary from Patient to Patient and can vary from a few days to weeks. How well your loved one recovers depends on a number of factors including severity of liver disease and amount of bleeding.
Are there any complications?
Complications may include continuous bleeding. If liver cirrhosis is the reason for the development of Oesophageal Varices and the bleeding, it is not uncommon for the blood to be very thin, as Liver Cirrhosis or Liver Failure often leads to Coagulopathy, which is a blood clotting and bleeding disorder). Clotting factors are usually chemically synthesised in the liver, however in Patients with Liver cirrhosis or Liver Failure, the liver is unable to synthesise the clotting factors and as a result the Patient is at high risk of bleeding.
Of course, if you have any questions or concerns, please discuss them with the ICU nurses and doctors.
All Intensive Care interventions and procedures carry a degree of potential risk even when performed by skilled and experienced staff. Please discuss these issues with the medical and nursing staff who are caring for your loved one.
