Fundoplication is a procedure used to relieve Gastro-Esophageal Reflux Disease (GERD) and its associated symptoms of heartburn and regurgitation of acid stomach contents.
The operation involves repairing any hiatus hernia which might be present, and then using part of the upper stomach (fundus), to wrap around the lower part of the oesophagus.
This creates a ‘valve between the oesophagus and the stomach, to prevent acid from the stomach refluxing into the oesophagus.
