Primary Outcome Measures:
  • Clinical success [ Time Frame: 3 months post procedure ] [ Designated as safety issue: No ]
    Clinical success defined as reduction of Eckardt score (0-12 scale achalasia least-most severe) of achalasia to an Eckardt score of 3 or less post procedure

Secondary Outcome Measures:
  • Adverse events [ Time Frame: 1 week post procedure ] [ Designated as safety issue: Yes ]
    All dilatation or POEM related adverse events, including type, required intervention, severity, time to resolution

Other Outcome Measures:
  • Cytokine levels [ Time Frame: Pre procedure and immediately and 6 hours post procedure ] [ Designated as safety issue: No ]
    Post procedural inflammation compared to baseline as measured by blood cytokine levels

  • Long term clinical success [ Time Frame: 6 and 12 months post procedure ] [ Designated as safety issue: No ]
    Long term clinical success at 6 and 12 months post procedure compared to baseline.

  • LES pressure [ Time Frame: 3, 6 and12 months post procedure ] [ Designated as safety issue: No ]
    Post procedure reduction in LES pressure at 3, 6 and 12 months compared to baseline.

  • Quality of life [ Time Frame: 3, 6 and 12 months post procedure ] [ Designated as safety issue: No ]
    Quality of Life (QOL) improvement at 3, 6 and 12 months post procedure compared to baseline using SF36 questionnaire

Estimated Study Completion Date: December 2015
Estimated Primary Completion Date: March 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Group A - POEM
Per Oral Endoscopic Myotomy for treatment of achalasia
Procedure: Per Oral Endoscopic Myotomy (POEM)
  • Mucosal incision - After submucosal injection, a 2-cm longitudinal mucosal incision is made at approximately 12 cm proximal to the gastroesophageal junction (GEJ).
  • Submucosal tunneling. A long submucosal tunnel is created to 3 cm distal to the GEJ.
  • Endoscopic myotomy is begun at 3 cm distal to the mucosal entry point, and is carried out in a proximal to distal direction to a total length of 10 cm.
  • Long endoscopic myotomy is performed 10 cm proximal to GEJ extending
  • Closure of mucosal entry: the mucosal incision is closed using hemostatic clips
Active Comparator: Group B - Dilatation
- Pneumatic dilatation using a balloon for treatment of achalasia.
Procedure: Pneumatic Dilatation
Pneumatic dilatation using a Rigiflex balloon up to 35 mm at 8 psi for 1 minute.

Detailed Description:

Achalasia is an esophageal motility disorder which involves smooth muscle of the esophagus and the lower esophageal sphincter (LES). Achalasia causes difficulty swallowing, regurgitation, and sometimes chest pain and weight loss. Endoscopic treatments of achalasia can be provided in the form of dilatation of the LES or cutting of muscle fibers (myotomy) of the esophagus and of the LES under endoscopic viewing. Dilatation in this trial is accomplished with rigiflex balloons and myotomy via Per Oral Endoscopic Myotomy (POEM). The effectiveness of treatment of achalasia using each method will be compared in this trial.
