HALO esophageal ablation is performed by your Gastroenterologist as a method of treating Barrett’s esophagus through a gastroscope. Barrett’s is a change in the lining of the esophagus, the swallowing tube that carries food and liquids to the stomach. You will be sedated. A gastroscope is used to examine the upper GI tract which includes the esophagus, stomach, and duodenum (the first portion of the small intestines) during an EGD procedure. This tube delivers precise controlled dosages of radio frequency waves to remove a thin layer of diseased tissue in the lower esophagus. This procedure takes approximately 45 minutes with an additional 30-60 minutes recovery time. You will need a driver to take you home because of the sedation. You are likely to experience some degree of pain in the post procedural period but will receive prescriptions to address this.
