The purpose of the study is analyze of the results of peroral endoscopic myotomy in patients with esophageal achalasia. Material and methods. In the period 2017-2022 years peroral endoscopic myotomy in esophageal achalasia was performed in 110 patients (43 - men, 77 - women). Mean aged from 7 to 75 years. The duration of the disease ranged from 6 months to 40 years. Results. In 109 cases, the intervention was technically successful.

When examining in the postoperative period and assessing the level quality of life using questionnaires SF-36, GIQLI and the Eckardt scale noted relief of dysphagia and a significant improvement in the main indicators. Conclusion. Peroral endoscopic myotomy in patients with esophageal achalasia can be the operation of choice in terms of efficiency, safety and long-term results, the level of quality of life in the postoperative period.
