Temporal variation in manometric findings in achalasia: a case report.

Esophageal manometry is a valuable tool in the diagnosis of achalasia. The manometric features proposed for diagnosing classic achalasia are incomplete relaxation of the lower esophageal sphincter and aperistalsis in the body of the esophagus. Atypical achalasia cases have been reported that do not have the characteristic manometric features of classic achalasia. We report the clinical, radiological and manometric follow-up of a 45-year- old woman who presented with atypical manometric features of achalasia that have not been reported in the literature and who after a short period demonstrated the manometric features of classical achalasia.
