A single institution's experience with more than 500 laparoscopic Heller myotomies for achalasia.
BACKGROUND
Long-term symptom relief and patient satisfaction after Heller myotomy are being reported. Herein, we report the largest experience of laparoscopic Heller myotomy for the treatment of achalasia.


METHODS
Since 1992, 505 patients have been prospectively followed after laparoscopic Heller myotomy. Until 2004, concomitant fundoplication was undertaken for a patulous hiatus, a large hiatal hernia, or to buttress the repair of an esophagotomy, then concomitant fundoplication became routinely applied. More recently, laparo-endoscopic single site (LESS) Heller myotomy has been performed when possible to improve cosmesis. Before and after myotomy, patients scored their symptoms.


RESULTS
Before myotomy, 60% of patients underwent endoscopic therapy; of these patients, 27% had Botox (Allergan) therapy alone, 52% underwent dilation therapy alone, and 21% had both. Esophagotomy occurred in 7% of patients. Concomitant diverticulectomy was undertaken in 7%, fundoplication was performed in 59%, and LESS Heller myotomy was done in 12%. Median length of stay was 1 day. With mean follow-up at 31 months, the severity of all symptoms improved significantly. After myotomy, 95% experienced symptoms less than once per week, 86% believed their outcome is satisfying or better, and 92% would undergo myotomy again, if necessary. Symptoms after myotomy are similar with or without fundoplication and regardless of the laparoscopic approach used.


CONCLUSIONS
Laparoscopic Heller myotomy safely and durably relieves symptoms of dysphagia. Confinement is short and satisfaction is very high. Relief of esophageal obstruction is paramount; the approach used or the application of a fundoplication has a lesser impact. Laparoscopic Heller myotomy, preferably with anterior fundoplication using a single site laparoscopic approach, is strongly encouraged for patients with symptomatic achalasia and is efficacious even after failures of dilation and/or Botox therapy.
