Brief Summary:
POEM is a new intervention for the treatment of achalasia and has been reported to relieve the dysphagia symptom effectively. Although the cost of POEM method is less than the method of Laparoscopic Heller Myotomy and Fundoplication, it is still of an economic burden for the patients with achalasia. In this trial, investigators plan to use snare to assist POEM procedure, to observe the safety, efficacy and cost-effectiveness of this method, compared with other knifes-assisted procedure.
