AI Summary Endoscopic variceal ligation (EVL) places small rubber bands around esophageal varices to prevent and treat bleeding, usually takes 15 to 30 minutes, and most people go home the same day.
Medically reviewed.
Endoscopic variceal ligation (EVL), also called variceal banding, is an endoscopic procedure that treats and prevents bleeding from esophageal varices. Varices are enlarged veins in the esophagus caused by portal hypertension. A doctor places small rubber bands around the varices. The bands cut off their blood supply, and the veins shrink. Treatment decisions should always be individualized and guided by a healthcare professional.
This page covers EVL: when it is recommended, how it works, what the procedure involves, benefits, risks, and follow-up care. You can also connect with a liver specialist near you for personalized guidance on whether EVL fits your care plan.

ABOUT ENDOSCOPIC VARICEAL LIGATION
Endoscopic variceal ligation (EVL), also known as variceal banding, is an endoscopic procedure. A doctor uses an endoscope, a flexible tube with a camera, to reach the esophagus. Through the endoscope, the doctor places small rubber bands around enlarged veins called esophageal varices. The bands cut off the blood supply to the varices and cause them to shrink.
Varices form when pressure rises in the portal vein, the main vein that carries blood to the liver. This is called portal hypertension. Varices can bleed, and the bleeding can be serious. EVL treats bleeding from varices and helps prevent it.
EVL is one of the endoscopic procedures used for varices. The other main option is endoscopic sclerotherapy, which injects a solution into the varices. EVL is the standard treatment for esophageal varices. It is also considered the gold standard for acute esophageal variceal bleeding.
WHO EVL MAY BE SUITABLE FOR
Your healthcare provider may recommend EVL if varices were found during an endoscopy, if you have bled from varices, or if you are at high risk of bleeding. It is also used to prevent bleeding from coming back.
For people with cirrhosis, a screening endoscopy is recommended when varices are a risk. People with medium or large varices, or with red signs on endoscopy, should receive preventive treatment with either non-selective beta-blocker medicines or EVL.
EVL may also be used when beta-blockers cannot be used. For people with high-risk varices who need blood thinners, non-selective beta-blockers are recommended first. EVL may be used if beta-blockers are not tolerated or not safe for the person. Blood thinners may need a short pause around the procedure.
EVL is used for esophageal varices. Varices in the stomach are treated differently. Every person's liver condition is different, so your care team decides which treatment is right for you.
ELIGIBILITY OVERVIEW
Your healthcare provider may recommend EVL for these reasons:
Before recommending EVL, your care team looks at several factors, including:
HOW EVL CAN HELP YOUR LIVER
EVL works by closing off the enlarged veins that can bleed. The doctor places small elastic bands around the varices. The bands block blood flow to those veins. Over time, the varices shrink and scar over.
This lowers the risk of bleeding and of bleeding again. It also helps manage complications of portal hypertension. EVL treats the varices themselves. It does not lower the pressure in the portal vein, so your provider may also prescribe medicine for portal hypertension, such as a non-selective beta-blocker.
EVL BENEFITS
Esophageal varices are a complication of portal hypertension, which can develop in people with cirrhosis. Varices can bleed, and the bleeding can be serious. EVL treats varices that have bled. It also helps prevent bleeding before it starts and stops it from coming back. By lowering the risk of bleeding and rebleeding, EVL helps protect you from a serious effect of liver disease.
EVL treats the varices themselves. It does not lower the pressure in the portal vein, so your provider may also prescribe medicine for portal hypertension, such as a non-selective beta-blocker. Together, these steps help protect you from the effects of liver disease.
EVL works best with liver-healthy habits. After treatment, keep taking the medicines your provider prescribes, avoid alcohol if it applies to you, and follow the diet advice from your care team. Attend your follow-up endoscopies so your team can check your progress. Your care team will still look after your liver disease as a whole.
Some people with liver disease cannot take non-selective beta-blockers, or do not tolerate them. EVL may be used in these cases to help prevent bleeding from high-risk varices. Your care team will decide which approach fits your health and other medicines.
EVL places small bands around esophageal varices to prevent and treat bleeding, without surgical incisions. It should only be done and followed under the guidance of a qualified healthcare team.
TREATMENT PROCESS
You are usually told to avoid food and drink for several hours before the procedure. Follow your care team's exact instructions.
You receive sedation before the procedure begins. The doctor passes a flexible endoscope through your mouth into the esophagus. A banding device on the endoscope places small rubber bands around the enlarged varices. The varices then collapse over time.
The procedure usually takes 15 to 30 minutes.
Most people go home the same day after a short observation period.
Follow-up endoscopies are often scheduled. They show whether treatment worked and whether you need more banding sessions.
BENEFITS AND SAFETY
EVL lowers the risk of bleeding from esophageal varices and helps prevent bleeding from coming back. It is a standard treatment for esophageal varices, and it is preferred over sclerotherapy for acute esophageal variceal bleeding. It is linked to better initial control of bleeding, lower rates of rebleeding, and fewer adverse events.
EVL is not a stand-alone plan. It works best with medicines for portal hypertension, follow-up endoscopies, and liver-healthy habits. If bleeding cannot be controlled with medicine and endoscopic treatment, your team may consider other options, such as TIPS.
Like any procedure, EVL has risks. Most are mild, such as a sore throat. Rare problems can be serious. Your care team will explain the risks before the procedure.
BENEFITS
EVL reduces the risk of variceal hemorrhage, which is serious bleeding from esophageal varices. It treats the varices before they have a chance to bleed, which lowers the chance of a first bleed.
If you have bled from varices before, EVL helps prevent repeat bleeding episodes. Treating the varices after a bleed lowers the chance that bleeding comes back.
EVL needs no surgical incisions. The doctor works through the mouth with an endoscope, so there are no surgical cuts to heal.
EVL is a standard treatment for esophageal varices. Compared with sclerotherapy, it is linked to better initial control of bleeding, lower rates of rebleeding, and fewer adverse events, which is why it is preferred for acute esophageal variceal bleeding.
Most of these effects are mild. Your healthcare provider will discuss the benefits and risks before treatment. Tell your care team about any symptoms that worry you after the procedure.
SUPPORTING YOUR RESULTS
After EVL, continue any medicines prescribed for portal hypertension, avoid alcohol if applicable, follow dietary and liver health recommendations, and attend scheduled follow-up endoscopies.
Follow-up visits matter because you may need more than one banding session. Your care team uses repeat endoscopies to check your progress.

COMMON QUESTIONS
Your healthcare provider may recommend Endoscopic Variceal Ligation (EVL) if varices were found during an endoscopy, if you have bled from esophageal varices, or if you are at high risk of bleeding. It is also used to prevent bleeding from coming back. For some people with cirrhosis, EVL is an alternative to non-selective beta-blockers. Your care team looks at the size of your varices, your bleeding history, and your overall liver health before deciding.
EVL is done with an endoscope, a flexible tube with a camera, passed through your mouth into the esophagus while you receive sedation. A banding device on the scope places small rubber bands around the enlarged veins. The bands cut off blood flow, and the varices shrink and scar over time. You are usually asked to avoid food and drink for several hours beforehand. Your care team will give you exact instructions.
Most people go home the same day after a short observation period. The procedure usually takes 15 to 30 minutes, and you receive sedation. Your care team will tell you how to prepare and what to expect afterward. Because recovery can differ from person to person, ask your provider about eating, activity, and which symptoms should prompt a call.
EVL lowers the risk of bleeding from esophageal varices and helps prevent bleeding from coming back. It is a standard treatment for esophageal varices. For acute bleeding, it is preferred over sclerotherapy because it is linked to better initial control, lower rebleeding, and fewer adverse events. EVL treats the varices but not portal hypertension itself, so you may also need medicine. Talk with your provider about what results to expect.
Most side effects of EVL are mild. Common ones include a sore throat, chest discomfort, ulcers at the banding sites, and bleeding. Rare problems include narrowing of the esophagus or a tear (perforation), which can be serious. Tell your care team about any symptoms that worry you after the procedure. Your healthcare provider will explain the risks and benefits before treatment so you can decide together.
You may need more than one session. Varices shrink and scar gradually, so follow-up endoscopies are often scheduled to check whether treatment worked and whether more banding is needed. Keep every follow-up visit, and keep taking any medicines your provider prescribes for portal hypertension, such as non-selective beta-blockers. Your care team will set a schedule based on your situation.
