"patchy alveolar opacities, usually bilateral, may be seen. These represent acute pneumonitis or chronic aspiration pneumonia related to dysphagia."
"type I: intermediate prognosis (81%), inversely associated with the degree of oesophageal dilatation"
"type II: very favourable prognosis (96%) 14"
"type III: less favourable outcomes (66%)"
"peroral oesophageal myotomy (POEM procedure) is a newer minimally invasive technique which may be used in select patients"

"Primary achalasia is most frequently seen in middle and late adulthood (age 30 to 70) with no gender predilection 6. Most cases are idiopathic; however, a similar appearance may occur in Chagas disease. Authors differ as to whether to reserve the term achalasia for idiopathic cases or include Chagas disease. Patients with Allgrove syndrome (triple A syndrome) also have achalasia, which is very similar to the primary form of the disease."
"scleroderma: gastro-oesophageal junction (GOJ) will be open; less severe dilatation"
"The lower oesophageal sphincter fails to relax, partially or completely, with elevated pressures demonstrated manometrically 4. This appears to be due to the loss/destruction of neurones in the Auerbach/myenteric plexus. Early in the course of achalasia, the lower oesophageal sphincter tone may be normal, or changes may be subtle."
"surgical myotomy (e.g. Heller myotomy)"
"after Heller myotomy, 10-30% of patients develop gastro-oesophageal reflux, and thus, it is often combined with a fundoplication (e.g. Dor, Toupet, Nissen)"
"There is a variable response to treatment following endoscopic or surgical myotomy, based on which achalasia subtype is present 11:"
