(a) Dilation of the esophagus. Dilated esophagus drooped to both sides of the spine.
(b) Food remnant in the esophagus
(c) Whitish coating of the mucosa caused by adhesion of the remained food inside of the esophagus and thickening of the mucosa
(d) Functional stenosis of the esophago-gastric junction. Endoscope passes through the tight segment with some resistance.
(e) Abnormal contraction of the esophagus. Simultaneous contraction is clearly observed.
Initial Management
•∆+: Barium esophagram with “bird-beak”, aperistalsis, and poor emptying of barium
•Treatment:
– Pneumatic dilation or surgical myotomy
– Peroral endoscopic myotomy (POEM)

– Esophagectomy : “ end-stage ” achalasia characterized by megaesophagus or sigmoid esophagus and signify cant esophageal dilation and tortuosity
– Other methodes: Botulinum toxin or calcium channel blocker
