Predictive factors of the therapeutic effectiveness in the treatment of Achalasia with balloon dilation

Background: Achalasia cardia is a rare primary esophageal motor disorder characterised by aperistalsis of the esophageal body and impaired lower esophageal sphincter relaxation. Pneumatic dilation is an effective treatment for achalasia. The aim of this study was to identify which factors are predictive for a good long-term success. Patients and methods: 380 consecutive patients (193 females, 187 males) were included in the study who had been treated by balloon dilation. The diagnosis was suggested by endoscopy and confirmed by esophageal manometry or barium esophagogram. The severity of achalasia was determined…
