A hiatus hernia is caused by part of the stomach and lower oesophagus bulging through the diaphragm (a sheet of muscle between the chest and the stomach) into the chest. A hiatus hernia can cause a burning feeling in the upper abdomen and chest (heartburn).

Laparoscopic Hernia Repair involves using surgical instruments to push the hernia back into its original position and repairing the weakness in the diaphragm.
