Esophageal Variceal Band Composition and Clinical Application

Material Composition

Esophageal variceal bands are made of elastic rubber material, specifically small elastic "O" rings designed for endoscopic ligation, according to the American Gastroenterological Association 1

The bands used in endoscopic variceal ligation (EVL) are standard rubber elastic bands that function as small "O" rings applied via specialized endoscopic devices, as recommended by the American Society for Gastrointestinal Endoscopy 1

Band ligation is the preferred first-line endoscopic treatment for esophageal varices over sclerotherapy due to its superior safety profile and comparable efficacy, as stated by the American College of Gastroenterology 4, 1
The ligated tissue falls off within 10-14 days, leaving shallow ulcers that heal over subsequent weeks, with a strength of evidence supported by the European Association for the Study of the Liver 2, 3
For gastric varices, particularly cardiofundal varices, band ligation is less effective than cyanoacrylate injection due to the larger size and deeper location of gastric varices, as reported by the Society of Interventional Radiology 4, 5
