Keyhole Surgery for Reflux
(Laparoscopic Nissen Fundoplication)



The oesophagus (gullet) enters the abdomen from the chest through a hole in the diaphragm. Sometimes this hole enlarges sufficiently for the top part of the stomach to herniate up into the chest (a hiatus hernia). This condition is often associated with reflux of acid from the stomach into the oesophagus. The first part of the operation is to separate the oesophagus from the diaphragm and place some stitches to narrow the hole so that it is only wide enough to transmit the oesophagus. Then a portion of the stomach is wrapped around the oesophagus to form a new valve that helps prevent reflux.
