Introduction Since peroral endoscopic myotomy(POEM)for the treatment of achalasia was first introduced by Inoue et al.[1]in 2010,various endoscopic knives including the Triangular-tip knife have been used during the procedure[2].To date,the investigation on endoscopic knives with good performance and low expense is still underway for patients with achalasia.In this case,we successfully carried out POEMassisted by a snare tip in a patient with achalasia.
