An assistant will be in the room to monitor your breathing and heart beat. You may also be given oxygen through your nose. A suction tube will be used to clear the saliva and other fluids from your mouth.
A lubricated endoscope will be placed into your mouth. It will be passed down your throat and into your esophagus. The scope will have a small light and a camera. The doctor will watch the images on a video monitor. Air will be passed through the scope to help your doctor see your esophagus. The doctor will be able to locate the enlarged vein.
Instruments will be passed through the scope. The enlarged tissue will be sucked into the device’s chamber. One or more bands will be placed around the tissue to clamp off the blood supply.
