GORD is caused by the backflow (reflux) of food and acid from the stomach into the oesophagus (the tube that connects the mouth to the stomach).  This happens when the valve between the lower end of the oesophagus and the stomach is not working properly.  The main symptom of GORD is heartburn (a burning feeling in the upper abdomen and chest).  Regurgitation of food is also common.  A hiatus hernia is often present, and is one of the causative factors behind reflux.

Laparoscopic Fundoplication for GORD involves wrapping the top part of the stomach (fundus) around the lower end of the oesophagus.  This creates a valve mechanism between the stomach and the oesophagus, thereby preventing further reflux of acid and food.
