Endoscopic Variceal Ligation (EVL) in Indore
Endoscopic Variceal Ligation (EVL), also called variceal band ligation, is an endoscopic treatment used primarily to control or prevent bleeding from enlarged veins, known as varices, in the esophagus. These enlarged veins can develop when increased pressure in the portal venous system causes blood to be redirected through smaller veins around the esophagus.
Esophageal varices are commonly associated with advanced liver disease and portal hypertension. Although varices may not cause symptoms until bleeding occurs, variceal bleeding can be a serious medical emergency requiring prompt specialist care.
During EVL, a gastroenterologist uses an endoscope to identify the varices and places small elastic bands around selected varices. The bands reduce blood flow through the treated veins, allowing them to shrink and eventually disappear.

What Is Endoscopic Variceal Ligation?
Endoscopic Variceal Ligation is a minimally invasive endoscopic procedure used to treat esophageal varices.
Varices develop when blood cannot flow normally through the liver and pressure builds up within the portal venous system. As a result, blood may be diverted through veins in the esophagus. These veins can become enlarged and fragile.
During EVL:
- An endoscope is passed through the mouth into the esophagus.
- The gastroenterologist identifies the enlarged varices.
- A specialised banding device is used to place small elastic bands around selected varices.
- The banded varices are deprived of their normal blood flow.
- The treated tissue gradually shrinks.
- The area eventually heals as part of the normal healing process.
EVL is primarily used for esophageal varices rather than treating the underlying liver disease itself. Management of the underlying liver condition and portal hypertension remains an important part of long-term care.
Why Do Esophageal Varices Develop?
Esophageal varices are most commonly associated with portal hypertension, which occurs when pressure increases within the portal venous circulation.
Advanced chronic liver disease and cirrhosis are important causes of portal hypertension. Scarring and changes in the liver can interfere with normal blood flow, increasing pressure in the portal circulation.
Other conditions affecting the portal venous system can also contribute to portal hypertension.
Patients with significant liver disease may therefore require assessment for complications such as:
- Esophageal varices
- Gastric varices
- Ascites
- Portal hypertensive changes
- Liver dysfunction
The underlying cause needs to be assessed alongside the management of varices.
What Are the Symptoms of Esophageal Varices?
Esophageal varices themselves often do not cause noticeable symptoms.
Symptoms can become apparent when a varix starts bleeding. Warning signs may include:
- Vomiting blood
- Black, tarry stools
- Dizziness or weakness
- Fainting
- Rapid heartbeat
- Symptoms associated with significant blood loss
Vomiting blood or passing black stools in a person with known or suspected liver disease requires urgent medical assessment.
Variceal bleeding can lead to significant blood loss, so emergency medical care should not be delayed.
When Is EVL Recommended?
EVL may be considered in patients with esophageal varices when endoscopic treatment is appropriate.
Depending on the clinical situation, EVL may be used for:
- Treatment of actively bleeding esophageal varices
- Prevention of recurrent variceal bleeding
- Management of high-risk esophageal varices when preventive endoscopic treatment is indicated
The decision depends on factors such as the severity of liver disease, portal hypertension, the size and characteristics of the varices, previous bleeding and the patient’s overall clinical condition.
EVL is generally part of a broader management strategy rather than a standalone treatment for liver disease.
How Is EVL Performed in Indore?
EVL is performed during an upper gastrointestinal endoscopic examination.
The general process involves:
- Clinical assessment: The gastroenterologist reviews the patient’s liver condition, symptoms, previous bleeding episodes and relevant investigations.
- Preparation: Appropriate fasting and medication instructions are provided before the procedure.
- Sedation or anaesthesia: Appropriate measures are used according to the procedure and clinical requirements.
- Endoscopic examination: The endoscope is carefully passed through the mouth into the esophagus.
- Identification of varices: The gastroenterologist examines the esophageal lining and identifies the relevant varices.
- Band placement: Small elastic bands are placed around selected varices using a specialised banding device.
- Recovery: The patient is monitored after the procedure and given appropriate post-procedure instructions.
- Follow-up: Additional endoscopic sessions may be required depending on the number and size of varices and the patient’s response.
The number and timing of follow-up treatments are individualized.
EVL for Variceal Bleeding
When esophageal varices bleed, the situation requires urgent medical management.
Endoscopic variceal ligation can be used as an endoscopic method to control bleeding from suitable esophageal varices. Treatment of an acute bleeding episode may also involve other medical measures and management of the underlying portal hypertension.
After the bleeding episode has been controlled, preventing another episode becomes an important part of long-term care.
Patients who have experienced variceal bleeding may therefore require ongoing specialist monitoring and appropriate secondary prevention strategies.
What Happens After EVL?
Following EVL, patients are monitored according to the extent of the procedure and their clinical condition.
Temporary symptoms may include:
- Mild chest discomfort
- Difficulty swallowing
- Throat discomfort
- A sensation of fullness or discomfort while swallowing
Patients are generally provided with specific dietary and activity instructions following the procedure.
The treated varices gradually shrink after band placement. Depending on the extent of varices, more than one endoscopic treatment session may be required.
Follow-up is important because varices can persist, recur or develop elsewhere as the underlying portal hypertension continues.
Is EVL Painful?
EVL is performed during an upper GI endoscopic procedure, with appropriate sedation or other measures to maintain patient comfort.
Some patients may experience mild chest discomfort or difficulty swallowing temporarily after the bands are placed. These symptoms generally relate to the treated areas and should be discussed with the treating medical team if they are persistent or severe.
The medical team provides post-procedure guidance specific to the patient’s condition.
Risks and Safety of EVL
EVL is an established endoscopic treatment, but like any medical procedure, it has potential risks.
Possible complications may include:
- Temporary chest discomfort
- Difficulty swallowing
- Bleeding from the banding site
- Ulcer formation at the treated site
- Rarely, more significant complications
The risk profile depends on the patient’s underlying liver disease, the severity of portal hypertension, the extent of varices and the circumstances in which EVL is performed.
Patients with active or recent variceal bleeding require particularly careful specialist management.
How Are Varices Diagnosed?
Upper GI endoscopy is an important investigation for directly identifying esophageal varices.
The evaluation may also include:
- Detailed medical history
- Physical examination
- Liver function tests and other blood investigations
- Assessment of liver disease
- Ultrasound or other imaging when appropriate
- Assessment for portal hypertension
- Upper GI endoscopy
The exact investigations depend on the patient’s symptoms, known liver disease and clinical findings.
Identifying varices is only one part of the evaluation. The gastroenterologist also considers the underlying liver disease and the patient’s overall risk.
