title: Laparoscopic Heller myotomy for classic achalasia: results of our initial series of 20 patients.
abstract: BACKGROUND
  The aim of this study was to review our results in the surgical management of achalasia by laparoscopic esophageal cardiomyotomy and partial fundoplication.
  
  
  METHODS
  The patient population was comprised of a consecutive series of 20 patients with classic achalasia who underwent laparoscopic cardiomyotomy and partial fundoplication. Clinical, radiological, and physiological characteristics were analyzed prospectively, with an emphasis on the outcome and complications.
  
  
  RESULTS
  There were 12 women and eight men; their mean age was 37 years. Four intraoperative complications occurred-two mucosal perforations that were resolved laparoscopically and two cases of pneumothorax. The median hospital stay was 4 days (range, 2-14) and the median time to start oral feeding was 3 days (range, 1-7). After a median follow-up of 14 months (range, 2-83), 16 patients were asymptomatic and four had mild heartburn and/or dysphagia. All patients gained weight (median, 8.0 kg; range, 1-23). We observed a median postoperative decrease in esophageal diameter of 1.6 cm (range, 0.2-2.9). Fifteen patients were subjected to physiological esophageal studies; the results showed that power esophageal sphincter pressure had decreased from 32 (range, 15-60) to 12 mmHg (range, 6-25). The median DeMeester score was 14.5 (range, 0.9-194). The median esophageal acid exposure was 3% (range 0-34.6).
  
  
  CONCLUSIONS
  Our initial experience with the laparoscopic management of classic achalasia yielded satisfactory clinical, radiological, and physiological results.
