Achalasia

Case contributed by Dr Ian Bickle

Presentation

Progressive swallowing difficulties, more so to solids.

Patient Data

Age: 41
Gender: Male
Barium

Dilated, adynamic esophagus with a fluid level and failure to empty.

Bird beak appearance at the GOJ. Trace of barium into the stomach.

Case Discussion

The appearances of achalasia are almost pathognomonic on barium swallow.  These include:

1.  A gas filled dilated esophagus on control film

2.  A distended esophagus with an air-fluid level

3.  An adynamic esophagus

4. A distal acute taper of the esophagus with a bird-beak appearance.

The bird-beak sign is used to refer to the tapering of the inferior esophagus in achalasia.   This has a smooth outline implying a non-malignant cause.    A rat's tail appearance is used interchangeably.
