AbstractAchalasia-patients investigated at Ullevål University Hospital this century were identified. Our aim was to evaluate diagnostics, treatment and follow-up. 21 patients were contacted by letter and 18 of these agreed to participate in a telephone interview conducted as a semi-structured questionnaire. They were also offered a consultation, endoscopy and manometry when indicated. This rare disease is difficult to diagnose and the symptoms are often misinterpreted as reflux, asthma or even referred for psychiatric treatment. In 15 out of 18 cases time from first consultation till diagnosis were two years or more, and in one third more than five years. Only two patients were diagnosed within two years from symptom debut. All patients, except one, were treated with either balloon-dilation or myotomy or with both. We found six cases where balloon dilations were repeated three times or more. 11 out of 18 had a myotomy, and in seven of these myotomy was the primary treatment. The questionnaire could not reveal any differences in patient satisfaction between the procedures, but 2/3 stated to be satisfied. The follow up of these patients has not been adequate and will be improved in the future.
