Laparoscopic Heller myotomy or pneumatic dilatation in achalasia: results of a prospective, randomized study with at least a decade of follow-up.

Background And Objectives: The most efficient long-term treatment strategy for achalasia has yet to be established. This study compared the long-term results (≥ 10 years) after either pneumatic dilatations or laparoscopic myotomy using treatment failure as the primary outcome. Secondary objectives were; the frequency and degree of dysphagia and effects on health-related quality of life (QoL).
