Laparoscopic Heller myotomy for achalasia: analysis of successes and failures.
OBJECTIVE
The outcome of laparoscopic myotomy for achalasia is dictated by many factors.


METHODS
A retrospective study was conducted between 1997-2007, 58 patients who fulfilled all criteria for the diagnosis of achalasia underwent laparoscopic Heller myotomy and 45 (77.6%) were included. Mean follow-up period was 36±15 months; 56 patients had Dor fundoplication; 17 patients had been previously treated by pneumatic dilatation. All steps of the procedure, esophageal manometric findings and radiological records were analyzed to determine factors contributing to the clinical success or failure of the operation. The main outcome measure was swallowing status.


RESULTS
Median hospital stay was 3±1 days and mean operative time was 75±20min. There were 7 intra-operative mucosal injuries; all sutured laparoscopically (5 had previous pneumatic dilatation). Good or excellent relief of dysphagia was obtained in 41 patients and was persistent among 2 patients (both had pneumatic dilatation preoperatively). The remaining 2 patients developed gastroesophageal reflux symptoms. These 41 patients had a preoperative smaller diameter of the esophagus (stage I, II and III), while those with guarding results (4) had stages III and IV. There was a decrease in LES pressure from 45±7mmHg to 10±2mmHg without evidence of restoration of esophageal peristalsis in any patient.


CONCLUSIONS
Laparoscopic Heller myotomy with Dor fundoplication significantly relieves the symptoms of achalasia without causing the symptoms of gastroesophageal reflux disease. A good postoperative result is expected when the length of myotomy is adequate, LES pressure declines substantially, preoperative esophageal dilation is not excessive and distortion of the distal esophagus is absent.
