In the European Achalasia Trial, treatment with pneumatic dilation or laparoscopic Heller myotomy was successful in a higher percentage of patients with type II achalasia than in patients with the type I or III form of the disease. Although success rates were high for both approaches in type II achalasia, the success rate was significantly higher in the group treated with pneumatic dilation. [14] However, relapse is common after pneumatic dilation; for good long-term outcomes, close follow-up and repeat dilation are required. [15]
