What is Cryotherapy (Cryospray) Ablation?
Cryotherapy ablation destroys the abnormal lining of the esophagus by exposing cells to extreme cold using liquid nitrogen. It is a new technique, which is done during an EGD (upper endoscopy). While you are sedated, a small tube is placed through your mouth into your stomach. This prevents air build-up in your stomach. Next, an endoscope (lighted tube with camera) is passed through the mouth into the esophagus, and liquid nitrogen is sprayed on the esophagus through a device passed through the endoscope. By freezing the tissues using liquid nitrogen, we hope to remove the abnormal cells and allow regrowth of new, healthy cells in their place.
