Study summary

Patients with newly diagnosed achalasia have been submitted to either treatment with pneumatic dilatation or surgical myotomy. Minimal follow up five years.

Read the detailed description

Patients with newly diagnosed achalasia have been submitted to either treatment with pneumatic dilatation or surgical myotomy. Minimal follow up five years.

During follow up patients have been interviewed with regular intervals, by use validated questionnaires. The level of symptom control has been assessed as well as the scoring cumulative incidence of treatment failures.

Health Related Quality of Life (HRQL) has been regularly checked.

Secondary outcomes

  1. Dysphagia scoring

    Dysphagia score according to standardized, validated scoring system.

    Time frame: At least five years after intervention

  2. Health Related Quality of Life

    Universally adopted and validated instruments are used.

    Time frame: At least five years after intervention.

  3. Direct medical costs.
