Cryoablation, sometimes called cryotherapy, is a minimally invasive treatment used to destroy diseased cells in the esophagus caused by esophageal cancer and/or Barrett's esophagus. For cryoablation, a physician inserts a small tube (endoscope) through your mouth and into your esophagus. Once the endoscope is in place, liquid nitrogen is sprayed through the endoscope into the esophagus. The liquid nitrogen freezes the lining of your esophagus. The frozen cells die and are replaced by healthy cells. Cryoablation is used to treat Barrett's esophagus with high-grade dysplasia, and some early stage esophageal cancers. It can also be used to improve symptoms of advanced cancers. These symptoms include difficulty swallowing and bleeding.
