What is Halo?
Halo is a new procedure to ablate Barrett's Esophagus and dysplastic cells in people who are found to have high grade dysplasia.
How is it performed?
A catheter is passed through an endoscope with a balloon fitted on the end. The balloon is positioned in the area where the treatment is to be done and it is inflated. Short bursts of energy are then delivered to the treatment area to burn or ablate the abnormal tissue. The advantage of Halo over other treatments is that the technology delivers a circumferential (360 degree) treatment to the area.
