Is secondary achalasia a reality? Primary versus secondary achalasia: Role of barium swallow
This study was conducted in the Department of Radiology Mayo Hospital, Lahore from January 2002 to December 2002. 30 Patients with findings on barium swallow of Achalasia were taken. Post procedure follow up was carried out either in the shape of endoscopic biopsy or post operative biopsy. The results showed that 25 out of 30 had Primary Achalasia and 5 had Secondary Achalasia. The results were compared with age of the patients and it was found that Secondary Achalasia, which was due to carcinoma of the lower esophagus or fundus of stomach, was virtually non existent before the age of 30. These were 5 patients all above 30 years of age.
