If your GERD (acid reflux) symptoms are severe and cannot be eased with medicine or lifestyle changes, your doctor may suggest surgery. Surgery for GERD is called fundoplication or Nissen fundoplication.

In many cases, surgery can lead to long-term control of acid reflux. If a hiatal hernia is causing GERD symptoms, your surgeon may also repair the hernia during this operation. A hiatal hernia occurs when part of your stomach pushes up into your diaphragm muscle.

During GERD fundoplication surgery, your doctor wraps the upper curve of your stomach (fundus) around the esophagus (tube that carries food and liquids from your mouth to your stomach). Your surgeon will then stitch it into place. This strengthens the valve between your esophagus and stomach, which stops acid from rising into the esophagus as easily.
