Video: Cryotherapy of the esophagus
Cryotherapy treatment for Barrett's esophagus uses extreme cold to destroy abnormal cells. A thin tube, or catheter, is guided through an endoscope to the site of the abnormal cells. Your doctor sprays liquid nitrogen onto the tissue to freeze it and destroy the cells. Cryotherapy may be repeated a number of times, with a month or two in between treatments.
