, were studied retrospectively. Before surgery, the demographics and the diagnostic test results were recorded. The patients submitted a dysphagia score for quality of life before and after surgery, and lower esophageal sphincter pressure (PLES) was measured. We also studied the difference produced in quality of life Results:Results: Results: Results: Results: 37 women and 23 men were followed. Mean age was 41.08 (12-87). There was no mortality and no conversions. The mean time of diet resumption was 1.6 day. The outcome was considered excellent in 80% of the series and intermediate in 20% of the series. The mean dysphagia score before surgery was 9.03 points, and after surgery, 1.7 point (maximum of 10 points), p=0.0001. The mean score decrease between pre-and postoperative scores was 7.33 points (87.17%). The mean PLES before surgery was 32.41 mmHg, and 12.7 mmHg after. Conclusion:Conclusion: Conclusion: Conclusion: Conclusion: HDL is a safe procedure and changed significantly the subjective quality of life scores, as well as the objective PLES means.
