Abstract BACKGROUND & AIMS: We compared findings from timed barium esophagrams (TBEs) and esophageal pressure topography studies among achalasia subtypes and in relation to symptom severity. METHODS: We analyzed data from 50 patients with achalasia (31 men; age, 20-79 y) who underwent high-resolution manometry (HRM), had TBE after a 200-mL barium swallow, and completed questionnaires that determined Eckardt Scores. Twenty-five patients were not treated, and 25 patients were treated (11 by pneumatic dilation, 14 by myotomy). Nonparametric testing was used to assess differences among groups of treated patients (10 had type 1 achalasia and 15 had type 2 achalasia), and the Pearson correlation was used to assess their relationship. RESULTS: There were no significant differences in TBE measurements between patient groups. Of the 25 patients who received treatment, 10 had a manometric pattern consistent with persistent achalasia after treatment (6 patients with type 1 and 4 patients with type 2 achalasia), whereas 15 appeared to have resolved the achalasia pattern (peristalsis was absent in 8 patients and weak in 7 patients). The height of the barium column at 5 minutes and Eckardt Scores were reduced significantly in patients who had resolved their achalasia pattern, based on HRM. The integrated relaxation pressure and the TBE column height correlated at 5 minutes (r = 0.422; P < .05). CONCLUSIONS: Patients who resolved their achalasia pattern, based on HRM, showed improved emptying based on TBE measurements and improved symptom scores. There was no significant difference between patients with type 1 or type 2 achalasia in TBEs. These findings indicate that normalization of the integrated relaxation pressure on HRM is a clinically relevant objective of treatment for achalasia. Copyright © 2013 AGA Institute.
