Abstract
Achalasia is a primary defect of esophageal motility of unknown aetiology, characterised by peristaltic dysfunction of the esophagus and impaired relaxation of the lower esophageal sphincter. The most common symptoms are dysphagia, regurgitation, weight loss, and chest burning. There are various treatment options for achalasia: botulinum toxin injections, pneumatic dilatation, Heller myotomy, and peroral endoscopic myotomy. The aim of the study was to access the efficacy and quality of life of patients with achalasia after surgical treatment — laparoscopic Heller myotomy and Dor fundoplication. All of the patients after surgery had a high gastrointestinal quality of life index. For all patients, during the follow-up period (median 2.4 years), the intensity of clinical symptoms after the procedure declined. Laparoscopic Heller myotomy with Dor fundoplication is a safe and effective method of treating achalasia and can reduce clinical symptoms and improve patients' quality of life.
