Achalasia is an uncommon esophageal motility disorder in which affected patients present with progressive dysphagia. Various causes were known in this disease. Esophageal achalasia is diagnosied by barium esophagogram, endoscopy and esophageal manometry. Treatment of esophageal achasia are pharmacotherapy, pneumatic dilatation, or botulinum toxin injection and surgical therapy. Balloon dilatation is a safe effective first line treatment. We report two cases of achalasia with normal lower esophageal sphincer pressure, typical endoscopic and typical esophagogram findings, which was treated successfully with pneumatic balloon dilatation.
