Oesophageal surgery is performed in conditions such as:
In achalasia, the lower end of the oesophagus does not relax and food can not pass through into the stomach. This results in regurgitation of food and unable to absorb nutrients, eventually leading to significant weight loss. It is also a risk of developing oesophageal cancer.
Oesophageal cancer incidence is increasing in the Western world. Surgery involved removal of most of the oesophagus and using either the stomach or large bowel to replace the oesophagus.
