Achalasia is a failure of the gastro-oesophageal sphincter (which lies between the stomach and the oesophagus) to open. This results in the accumulation of food and saliva in the oesophagus and dilation of the oesophagus - a condition called megaoesophagus. Achalasia occurs in humans but, although the term has been used in the veterinary literature, it is not thought to be a common cause of megaoesophagus  in animals
