The recent surgical treatment could only be developed after advances in knowledge of the pathogenesis and pathophysiology fisipoatologia achalasia were reached. A cluster consisting of varied autoimmune diseases has been linked to achalasia: It is well known that the resting tonus of the LES is regulated by excitatory acetylcholine, Substance P, among othersas aca,asia as inhibitory neurotransmitters nitric oxide.

An upper digestive endoscopy and esophagogram were carried out, owing to the predominant dysphagy-related symptoms, both suggestive of esophageal achalasia involving the lower esophageal sphincter LES.


The prevalence of autoimmune disease in patients with esophageal achalasia.

This alteration in the myenteric plexus has been explained by different etiopathogenic mechanisms: Diseases associated with thyroid autoimmunity: By contrast, only 4. Impermeable cardiospasm successfully treated by thoracothomy and esophagoplication.
