Esophageal varices are abnormal blood vessels (veins) that develop in the esophagus. They have abnormally thin walls, and the blood pressure within them is very high. This combination makes esophageal varices very dangerous, because they can burst and cause life-threatening bleeding.

Endoscopic band ligation is the use of elastic bands to treat the varices. It is done as part of an upper gastrointestinal (GI) endoscopy.
