what does a nissen fundoplication mean
In brief: Acid reflux surgery. A nissen fundoplication is a surgery for gerd or acid reflux. It is usually performed laparoscopically. The main components of the surgery are repair of a hiatal hernia, if present, followed by wrapping of the upper part of the stomach (the fundus) around the esophagus. This repairs the valve between the esophagus and stomach and prevents reflux.
