This is a study of the safety and efficacy of a new surgical procedure using endoscopic instruments and a tunneling technique to reach the LES for dissection. We hypothesize that this technique provides an incisionless, less invasive option with similar functional outcome compared to standard Heller myotomy.

Primary Outcome Measures:
  • Improved quality of life as defined by survey pre and post surgery [ Time Frame: six months ] [ Designated as safety issue: No ]
    patients diagnosed with achalasia will be given a quality of life survey before surgery and again six months after surgery.

Secondary Outcome Measures:
  • Negative pH test [ Time Frame: six months ] [ Designated as safety issue: No ]
    Patients will be required to have 24 hour pH testing after surgery.

  • Bleeding [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]
    recorded blood loss will be taken during surgery.

Detailed Description:
By the endoscopic creation of an esophageal submucosal tunnel the inner circular muscle layer can be easily visualized. In contrast to conventional Heller myotomy, the dissection of only the inner circular esophageal muscle layer leaves the outer longitudinal muscle layer intact. Thereby, post-interventional reflux disease should be avoided.
