We experienced a case of Achalasia, who had been impressed as a bronchial asthma and treated at a local clinic. Fluoroscopic findings revealed narrowed vestiblar portion with markedly dilated body of the esophagus. Hypertrophied mucosal folds on lower portion of the esophagus were noticed by the esophagoscopy but no ulcerative lesion, nor mass were found. The symptoms such as dysphagia, regurgitation, cough and retrosternal discomfortness were markedly relieved by means of daily mercury bougenagie for a month duration.
