Esophageal varices are dilated veins of the portal systemic system, which pass through the lower area of the esophagus. Patients presenting ruptured esophageal varices have a 40-70% fatality rate, and recurrent bleeding is typical. The Oregon Medical Laser Center has created a chitosan dressing for the Department of Defense to be used on massive hemor-rhages. To extend the application of chitosan bandages for hemorrhage control and tissue repair of esophageal varices, the Clinic team has designed a non-invasive endoscopic delivery system of a chitosan bandage for use under video guidance.
