Surgical management of achalasia.

Although achalasia is not a common illness in the United States and Europe, there continues to be a need for surgical therapy for treatment. Laparoscopic Heller myotomy and partial fundoplication has, for the most part, replaced open surgery (abdominal or thoracic) as the surgical treatment of choice. In order to perform this procedure well, one must select patients carefully, evaluate them fully, and adhere to the technical principles required to achieve consistently good results.
