Procedure: Per oral endolumenal myotomy
In this study, the investigators propose the use of a recent endolumenal technique for partial myotomy in patients suffering from esophageal achalasia.
Under general anesthesia patients will have upper endoscopy. Submucosal injection and mucosal incision is created for entry into the submucosal space. A submucosal tunnel is then created using a needle knife or blunt dissection as appropriate. Dissection will continue distally beyond the lower esophageal sphincter. The inner circular muscle fibers will then be divided to achieve an adequate myotomy length. The mucosal entry is then closed appropriately.
Results will be compared to historical data of conventional Heller myotomies.
