Various gastroenteric surgical procedures have been attempted laparoscopically. Laparoscopic esophagomyotomy (LE) with or without fundoplication, performed for achalasia, has gained popularity. In our clinic, LE (Heller's myotomy) was performed on six patients with achalasia. All patients underwent barium esophagography, endoscopy, and esophageal manometry for diagnosis. Extramucosal myotomy was started 6 cm above the cardioesophageal junction on the left anterolateral aspect of the esophagus and continued 1 cm below this area. Endoscopic control of the distal esophageal mucosa and the stomach was carried out under direct laparoscopic visualization following the completion of myotomy during the operation. EE was completed without complication in five patients. In one patient (16%), mucosal perforation occurred after myotomy during endoscopic control and was repaired with endostitches. These were no postoperative complications. The average hospital stay was 3 days. Three of the six patients agreed to 24-h pH monitoring, the results of which showed no evidence of reflux. All patients were completely symptom free in the postoperative period. The average preoperative lower esophageal sphincter pressure was 44 mm Hg, whereas in the early postoperative period and 6 months later, it was II mm Hg. There was no dysphagia or reflux esophagitis during the follow-up period (range 12 to 24 months). LE is associated with low morbidity and a high success rate, comparable with an open procedure, and can be done without an antireflux procedure.
