Gastroesophageal Reflux Disease, or GERD, is often the result of a hiatal hernia or weakness of the valve called the lower esophageal sphincter. Over time, reflux can lead to Barretts esophagus, dysplasia and even esophagus cancer (adenocarcinoma.) This video shows how an operation called fundoplication can help prevent acid from splashing into the esophagus. Mayo Clinic has a very large team with an international reputation for its skill in diagnosing and treating reflux, Barretts esophagus and esophagus cancer.
