A thorough history and physical examination swallowing and deficient progressive peristalsis within the may help identify the cause, which may include anatomic, esophagus which is present with normal swallowing. A differential diagnosis balloon dilatation may be used to treat the symptoms of early is provided in Table 52. Esophageal diverticula are categorized as either pulsion or cular muscles of the esophagus and is extended through the traction diverticula. Traction diverticula occur in the middle lower esophageal sphincter onto the stomach. Treatment is medical, rather accompanied by an antireflux procedure (usually a partial than surgical. If the barium swallow reveals an obstructing lesion or steno- false diverticula caused by uncoordinated swallowing and they sis, endoscopy with biopsy is indicated. If the lesion is benign form at a weak point just distal to the cricopharyngeus muscle.

The second diagnostic procedure is endoscopy to rule present with advanced disease and the goal then becomes pal- out carcinoma. If a mechanical obstruction is not found, then liation; this can be achieved with an endoscopically placed manometry is done. The typical manometric findings include esophageal stent as well as with laser ablative therapy.

When the barium swallow is normal, endoscopy should be performed to rule out a false-negative study.
