Original method of surgical treatment of patients with II-III stage esophageal achalasia -- total demuscularisation of affected esophageal part, selective proximal vagotomy, and formation of invaginated valve from autologous tissues -- is analysed. Overall 39 patients aged 23 to 62 years with II (6) and III (33) stage esophageal achalasia have been operated. There were no specific postoperative complications. Mean hospital stay was 6,5 +/- 1,2 days. Long-term results evaluated from 1.5 months to 5 years after surgery demonstrated good anatomic and functional results confirmed with special methods of examination and CIQLI scale of life quality.
