John C. Lipham, MD, associate professor of clinical surgery at Keck School of Medicine of USC, in this ABC7 segment treats a patient who has Barrett’s esophagus, a precursor to cancer. The condition signifies damage to the lower esophagus and happens to people who are long-term sufferers of GERD (gastroesophageal reflux disease), but it largely has no symptoms. Dr. Lipham treats the patient with the LINX Reflux Management System, a ring of magnets that encircles the area where the stomach and esophagus meet, which is said to be a life-changing step in fighting Barrett’s, GERD and esophageal cancer. He is one of the few doctors in the country licensed to perform the LINX procedure.
