What Is Endoscopic Variceal Ligation (EVL) and What Is It Used To Treat?

Endoscopic Variceal Banding or Endoscopic Variceal Ligation (EVL) is a procedure related to gastroenterology, in which a doctor (gastroenterologist) will use an endoscope to place an elastic ring around an enlarged vein. Banding the vein in this manner cuts off the blood flow through the vein, and stops variceal bleeding, which is what this procedure is used to treat.

Stopping immediate (acute) variceal bleeding is the most common motive of EVL. In people who have cirrhosis, high pressure in veins that carry blood from the intestines to the liver (portal hypertension)

causes many problems. Variceal bleeding, which is bleeding from enlarged veins (varices) in the digestive tract is an extremely serious complication of portal hypertension. For people who have advanced cirrhosis and varices especially in the oesophagus, the risk of variceal bleeding is high. After varices have bled the first time, there is a high risk of bleeding again. If the varices are not treated, bleeding can also lead to death. Variceal bleeding is the most severe complication of cirrhosis and is the second most common cause of mortality among the patients.

Variceal banding is often done several times to control the

varices

and

control

bleeding. As an example, banding may be repeated

every 2 to 4 weeks for 3 to 4 sessions. The doctor will monitor the varices every 3 to 12 months for the rest of the patient’s life.

There are certain multi-facility, super-specialty hospitals in Patna, where one can find the leading gastroenterologists in Patna for EVL procedure and other gastric problem treatment. Other more advanced techniques like argon plasma coagulation (APC) and endoscopic sclerotherapy can also be used in combination with EVL to prevent variceal recurrence.

These procedures will only be found in advanced hospitals which have state of the art technology and equipment, found only in metropolitan cities.
