Our institution introduced laparoscopic surgery for esophageal achalasia in 2001. The present report summarizes 15 cases of achalasia treated with laparoscopic Heller myotomy and anterior fundoplication according to the method of Dor, and we have investigated the therapeutic effects on specific symptoms such as dysphagia, reflux, and chest pain. From February 2001 through January 2007, the laparoscopic Heller-Dor operation was performed in 15 patients, including 7 men and 8 women. Achalasia was classified morphologically on esophagography as spindle type in 11 cases, flask type in 3 cases and sigmoid type in 1 case. The degree of esophageal dilatation was classified as grade I in 8 cases, grade II in 6 cases, and grade III in 1 case. Dysphagia was the main symptom and was present in all cases. The mean disease duration was 4.3 years (range, 5 months to 20 years), and the mean weight loss was 4.2 kg. All patients underwent endoscopic dilatation preoperatively. Intraoperative blood loss ranged from 0 to 100 mL (mean, 21 mL). Adequate Heller myotomy was considered more than 6 cm and more than 3 cm in the esophagus and the stomach, respectively. Injury to the esophageal mucosa occurred during the myotomy in 3 cases but could be repaired in all cases during the laparoscopic procedure. All patients reported an excellent level of satisfaction postoperatively. In conclusion, the laparoscopic Heller-Dor operation for esophageal achalasia is a useful procedure because the postoperative satisfaction level of patients is excellent. Despite the risk of mucosal injury, adequate Heller myotomy should be achieved to obtain a good prognosis. It is, therefore, of utmost importance to obtain mastery over the surgical technique to repair any mucosal injury that might occur.
