Keck USC Upper GI division is proud to partner with EndoStim, a new, minimally-invasive approach to GERD treatment, designed to restore normal function to the lower esophageal sphincter (LES). If you are interested in participating in the LESS GERD Trial, please go to http://www.lessgerd.com/ to see if you qualify.

Introduction to GERD
GERD is a disorder of the Lower Esophageal Sphincter. In healthy patients, the Lower Esophageal Sphincter creates a valve that prevents bile, pancreatic enzymes, and stomach acid from traveling back up into the esophagus where they can cause burning and damage to the esophageal tissue. When the Lower Esophageal Sphincter is weak, this allows acid, bile and pancreatic enzymes to reflux up into the esophagus. Most commonly, the refluxed gastric contents are acidic, and typical medical therapy for reflux disease consists of drugs to neutralize or suppress gastric acidity.
GERD occurs when the lower esophageal sphincter (valve) between the stomach and esophagus is weak or opens abnormally. Stomach juices reflux into the esophagus and may injure the esophagus and cause symptoms of heartburn or regurgitation.
However, bile and pancreatic enzymes are also contained within the fluid that is refluxed up into the esophagus. Neutralization or blockage of acid secretion does not prevent injury to the esophagus from these non-acid components of refluxed material. Consequently, one of the major pitfalls of medical therapy for reflux disease is that although acid production is suppressed and heartburn is often decreased or eliminated, reflux and esophageal injury may continue. It has been shown in multiple studies that patients reflux the same amount on or off medications.
