Secondary achalasia or pseudoachalasia
is a term used to describe acquired esophageal/ motor abnormalities that are similar to primary achalasia.
12) Upper gastrointestinal (GI) endoscopy is also used to identify the condition but its use is mainly to identify cases of pseudoachalasia due to malignancy.
Upper GI endoscopy has been primarily used to identify pseudoachalasia.
Pyloric outlet obstruction can occur with tumors of the antrum and pylorus, and tumors of the cardia can cause dysphagia due to involvement of the lower esophageal sphincter and development of pseudoachalasia
Overinflation of the band can result in obstructive symptoms with pseudoachalasia
seen on UGI series (Figure 12).
Additionally, upper endoscopy (EGD) was performed to rule out masses and pseudoachalasia
3) A more rapid onset and progression of symptoms (less than 6 months) is suggestive of pseudoachalasia and cancer.
3) Manometry cannot, however, reliably distinguish primary achalasia from pseudoachalasia.
, oesophageal motor dysfunction is not caused by a primary denervation disorder but rather by neoplasm or postoperative obstruction of the oesophagogastric junction.
patients tend to be older than esophageal achalasia patients at first symptom onset (69 years vs 53 years).
Proximal tumors may cause dysphagia or pseudoachalasia
, while distal tumors may result in symptoms of gastric outlet obstruction.
