Abstract
Purpose: The purpose of our study was to evaluate the role of timed barium esophagogram (TBE) in quantitative measurement of improved esophageal emptying in primary achalasia patients treated with POEM. Also, we investigated the correlation of TBE with improvement of clinical symptoms as measured by Eckardt score.

Methods: This retrospective study included 30 patients who underwent POEM due to primary achalasia. As a baseline study, all patients underwent TBE and were evaluated for clinical status by Eckardt score based on presence and frequency of dysphagia, regurgitation, substernal pain, and weight loss. Follow-up evaluation was performed within 3 months after POEM. Pre- and post-POEM TBE results were compared using a calculated value based on summation of height of the barium columns on 1-, 2- and 5-min delayed images. Also, the correlation of TBE with improvement of Eckardt score was evaluated using Pearson's correlation test.

Results: There was a significant decrease in the calculated value of height between pre- and post-POEM TBE studies (40.5 ± 15.8-17.0 ± 11.6, p < 0.01). Also, the Eckardt score decreased significantly after POEM (6.7 ± 2.0-0.8 ± 1.0, p < 0.01). Pearson's correlation test revealed a positive correlation between improvement of TBE results and Eckardt score (correlation coefficient = 0.56, p < 0.01).

Conclusion: TBE is an objective method for quantitative measurement of improved esophageal emptying in primary achalasia patients treated with POEM and shows positive correlation with clinical symptoms evaluated by Eckardt score.
