The diagnostic criterion for achalasia is at least consistent with the following items: barium esophagogram may reveal a classic "bird's break" appearance, esophageal dilation, or a corkscrew appearance with aperistalsis; HRM manifests aperistalsis and failure of relaxation of the LES [15, 16].
Initial ultrasound examination showed a moderately dilated fetal stomach, distended bowel loops, and aperistalsis (Figure 1).
Aperistalsis on esophageal manometry confirmed diagnosis of achalasia.
Systemic manifestations include proximal myopathy, inflammatory polyarthritis, central nervous system symptoms, esophageal aperistalsis, and hoarseness.
(1) Achalasia is characterised by oesophageal aperistalsis and increased resting pressure with partial or incomplete relaxation of the lower oesophageal sphincter.
In the oesophageal phase, complete aperistalsis, simultaneous oesophageal spasms, slower oesophageal transit, and deficit in sphincter relaxation and pressure have been the predominantly observed abnormalities [67, 70].
On imaging and manometry, achalasia is further characterized by esophageal aperistalsis and failure of the lower esophageal sphincter to relax.
(2) Achalasia is a disease of unclear etiology, characterized by aperistalsis in the body of the esophagus and failure of relaxation in the lower esophageal sphincter (LES).
Achalasia is characterized by an incomplete relaxation of the lower esophageal sphincter (LES) accompanied by aperistalsis of the esophageal body.
Achalasia is an idiopathic motility disorder of the oesophagus characterised by aperistalsis of the oesophageal body and incomplete relaxation of the lower oesophageal sphincter during swallowing (1).
