AI Summary Endoscopic variceal ligation (EVL) is the preferred endoscopic procedure for acute esophageal variceal bleeding, and sclerotherapy is used when EVL is not feasible or available.
Medically reviewed.
Endoscopic procedures are treatments that use an endoscope, a flexible tube with a camera, to find and treat complications of liver disease, mostly portal hypertension in cirrhosis. Portal hypertension is high pressure in the portal vein, the main vein that carries blood to the liver. They are used most often for esophageal varices, which are enlarged veins in the esophagus that can bleed. The two main procedures are endoscopic variceal ligation (EVL), which places small rubber bands around varices, and endoscopic sclerotherapy, which injects a solution into or around them.
This page explains what endoscopic procedures are, who may need them, how they compare, and what follow-up care involves. You can also connect with a liver specialist to discuss whether one of these procedures fits your care plan.

ENDOSCOPIC PROCEDURES OVERVIEW
Endoscopic procedures use an endoscope to diagnose and treat complications of liver disease, especially portal hypertension and cirrhosis. Portal hypertension is high pressure in the portal vein, the main vein that carries blood to the liver. It can cause varices, which are enlarged veins that may bleed. Treatment plans are personalized based on your diagnosis, your overall health, and whether bleeding has occurred.
You can explore the two main endoscopic procedures below and learn how each one treats varices. Because the right choice depends on your specific situation, connecting with a liver specialist can help you understand which option fits your care plan.
EVL, also called variceal banding, places small rubber bands around enlarged veins in the esophagus. The bands cut off blood supply, and the veins shrink and scar over time. The procedure usually takes 15 to 30 minutes, and most people go home the same day.
Explore this procedure:
Sclerotherapy injects a sclerosing solution into or around enlarged veins in the esophagus. The solution causes the veins to clot and scar, which helps control bleeding. The procedure typically takes 20 to 45 minutes, and a hospital stay may be needed depending on how severe the bleeding is.
Explore this procedure:
Providers may recommend EVL for people whose endoscopy shows esophageal varices, who have had variceal bleeding, or who are at high risk of bleeding or rebleeding. Sclerotherapy is used for active bleeding, or when EVL is not feasible or available.
DIET & LIFESTYLE SUPPORT
Endoscopic procedures work best as part of a full care plan for portal hypertension. Taking your medicines, avoiding alcohol if it applies to you, eating well, and keeping follow-up visits all support your recovery and long-term liver health.
Keep taking the medicines your provider prescribes for portal hypertension, such as non-selective beta-blockers if they are right for you.
Avoid alcohol if it applies to you, and follow the dietary and liver health recommendations from your care team.
Keep your scheduled follow-up endoscopies and appointments so your care team can check how treatment is working.
Follow the dietary recommendations from your care team. Amsety nutrition bars are designed for liver health and can be one option to discuss with them.

ENDOSCOPIC PROCEDURES AND PORTAL HYPERTENSION
Endoscopic therapy is mostly used for complications of portal hypertension in cirrhosis. These include esophageal varices, gastric varices (enlarged veins in the stomach), and portal hypertensive gastropathy (a fragile stomach lining that can bleed). It can also treat bile duct strictures and remove bile duct stones that cause a blockage.
Endoscopic therapy is the first course of treatment for bleeding varices. It is often combined with medicines, and sometimes with other procedures if bleeding does not stop. The rows below show where each option fits.
EVL is the gold standard for acute esophageal variceal bleeding. It is preferred over sclerotherapy because it is linked to better initial control of bleeding, lower rates of rebleeding, and fewer adverse events.
Sclerotherapy is used during active bleeding, after variceal bleeding when more treatment is needed, or when EVL is not feasible or available. Doctors may also choose it when the view is too blocked by blood for banding. It can treat esophageal or gastric varices, and it is a non-surgical option for emergency bleeding control.
When bleeding from varices is suspected, doctors start medicines that lower pressure in the portal vein as soon as possible, often in the emergency room. These medicines can make the varices easier to see and help control bleeding. You also receive short-term antibiotics when you are admitted, because infections are a major risk after variceal bleeding. Your care team may also give fluids and, if needed, a blood transfusion to keep you stable.
When varices bleed, endoscopy should happen as soon as you are stable, and within 12 hours of arriving for care. People with very high-risk or massive bleeding, such as those whose blood pressure stays unstable despite treatment, may need emergency endoscopy within 6 hours.
Gastric varices are harder to reach than esophageal varices and often need a different approach than banding. For varices in the upper part of the stomach, the first-line endoscopic treatment is an injection of tissue glue (cyanoacrylate). The glue causes the vein to clot right away. If glue does not work or cannot be used, doctors may consider TIPS or BRTO instead.
After a bleeding episode, preventing another one starts once you are stable and the first five days have passed. The standard approach combines a non-selective beta-blocker, such as carvedilol or propranolol, with repeated EVL sessions until the varices are completely gone. Banding can also be used to prevent a first bleed in people whose varices are at high risk.
If bleeding continues despite medicines and endoscopic therapy, or returns during the same hospital stay, doctors may place a TIPS as a rescue treatment. TIPS is also a second-line option for people who rebleed even though they take a beta-blocker and have regular EVL. Your specialist can explain which option fits your situation.
FOLLOW-UP CARE
Follow-up care helps your healthcare provider check how well treatment is working and decide whether you need more sessions. Knowing what to expect after a procedure also helps you spot problems early.
Follow-up endoscopies are often scheduled to see how the varices responded and whether more banding or injection sessions are needed.
After EVL, most people go home the same day after a short observation period. After sclerotherapy, you are monitored and may need to stay in the hospital, depending on how severe the bleeding was.
After EVL, common risks include sore throat, chest discomfort, ulcers at the banding sites, and bleeding. Narrowing or a tear in the esophagus is rare. Ask your provider which symptoms need urgent attention.
Only a qualified healthcare provider can decide which procedure is right for you and adjust your plan based on your results and health history.
COMMON QUESTIONS
Endoscopic procedures treat complications of portal hypertension, mainly bleeding esophageal varices. A doctor passes a flexible tube with a camera (an endoscope) through the mouth to reach the veins. The two main procedures are endoscopic variceal ligation (EVL) and endoscopic sclerotherapy. Talk with your liver specialist about whether one fits your treatment plan.
EVL places small rubber bands around enlarged veins, while sclerotherapy injects a solution into or around them. Both cause the varices to shrink and scar. EVL is the preferred option for acute esophageal variceal bleeding because it is linked to better bleeding control, less rebleeding, and fewer adverse events. Sclerotherapy is used when EVL is not feasible or available.
Providers may recommend an endoscopic procedure if you have esophageal varices, have had variceal bleeding, or are at high risk of bleeding or rebleeding. Sclerotherapy is also used for active bleeding or when EVL is not an option. Your provider decides based on your diagnosis, your overall health, and what your endoscopy shows.
You will usually be told to avoid food and drink for several hours before the procedure. You receive sedation for EVL, and may receive intravenous medicines before sclerotherapy. EVL usually takes 15 to 30 minutes, and sclerotherapy typically takes 20 to 45 minutes. Your care team will give you instructions for your situation.
Many people go home the same day after EVL. After sclerotherapy, you are monitored and may need a hospital stay, depending on how severe the bleeding was. Follow-up endoscopies are often scheduled to check your response and decide if you need more sessions.
Common risks of EVL include sore throat, chest discomfort, ulcers at the banding sites, and bleeding. Narrowing or a tear in the esophagus is rare. Ask your provider about the risks of your specific procedure and which symptoms need urgent care.
