Background: Achalasia is a primary esophageal motor disorder involving the body of the esophagus and lower esophageal sphincter. The mechanism is destruction of the myenteric plexus after a viral infection. Multiple methods of treatment with variable results induced in achalasia. Materials and Methods: We analyzed 70 patients with achalasia that underwent surgical treatment with transabdominal or transthoracic cardiomyotomy from 1982 to 2008 in Mashhad (Ghaem and Omid) hospital and at least 2 years follow up for evaluated result of surgery.Results: The mean age was 39.2 ± 9.42 years and the M/F = 0.89. The most common symptom was dysphagia (100%). The interval between beginnings of symptoms to a definitive diagnosis was 10.6 ± 8.3 month. The ratio between the two techniques was 35/35 = 1. In 67.1% of patients, a previous history of pneumatic dilation was reported. Long-term good results after surgery were seen in 77.2% of patients. Recurrence after surgical treatment was seen in 22.8%. A comparison of the two techniques (with or without antireflux surgery), showed a greater failure rate in transabdominal cardiomyotomy without the antireflux protocol (8/15 = 40%), but by the chi- square test, the difference was not statistically significant (P = 0.107). The most common complication after surgery was esophageal leakage (2.85%), and mortality was zero. In recurrence, most patients underwent pneumatic dilation (9/16 = 56.2%), and if surgery was needed, all patients underwent a transthoracic approach with antireflux treatment.Conclusion: Based on the good, long-term results with the surgical treatment of achalasia, surgery is recommended in most patients. A transthoracic or transabdominal approach had good, long-term results, but a transthoracic approach had better results and usually did not need antireflux surgery.
