title: [Laparoscopic Heller myotomy for esophageal achalasia].
abstract: BACKGROUND
  Achalasia is characterized by an incomplete relaxation of the lower esophageal sphincter. The best treatment is surgical and the laparoscopic approach may have good results.
  
  
  OBJECTIVE
  To assess the results of laparoscopic Heller myotomy among patients with achalasia.
  
  
  METHODS
  Prospective study of patients subjected to a laparoscopic Heller myotomy between 1995 and 2004. Clinical features, early and late operative results were assessed.
  
  
  RESULTS
  Twenty seven patients aged 12 to 74 years (12 females) were operated. All had disphagia lasting for a mean of 32 months. Mean lower esophageal sphincter pressure ranged from 18 to 85 mmHg. Eight patients received other treatments prior to surgery but symptoms persisted or reappeared. The preoperative clinical score was 7. No patient died and no procedure had to be converted to open surgery. In a follow up of 21 to 131 months, all patients are satisfied with the surgical results and the postoperative clinical score is 1. Only one patient with a mega esophagus maintained a clinical score of six.
  
  
  CONCLUSIONS
  In this series of patients, laparoscopic Heller myotomy was an effective and safe treatment for esophageal achalasia.
