Achalasia of the oesophagus: management by videoendoscopic surgery
Achalasia of the oesophagus is a neuromuscular disorder which leads to oesophageal dilatation in the absence of a mechanical obstruction. Dilatation appears to be related to the inability of the oesophagus to generate adequate propulsive waves and sufficient relaxation in response to swallowing. The disease affects men more often than women, and its peak incidence is between 30 and 60 years. The cause is not known, but it is thought to be related to a degenerative or infectious process which causes the destruction of the ganglion cells of Auerbach’s myenteric plexus and a hypertrophy of the circular muscle of the distal oesophagus. In areas where trypanosomiasis is endemic, such as Brazil, oesophageal dilatation similar to achalasia is seen in patients affected by Chagas’ disease.
