NCT04798547

Brief Summary

The objective of this randomized controlled trial (non-inferiority study) is to evaluate the outcomes of 4 cm short myotomy compared to the 8 cm standard length myotomy in Per-Oral Endoscopic Myotomy (POEM) for patients with achalasia. We hypothesize that a shorter myotomy with POEM will have the same clinical efficacy as standard length myotomy based on patient-reported Eckardt score with shorter procedure times and reduced complications.

Outcome Measures

Primary Outcomes (1)

  • Compare symptomatic improvement of achalasia based on Eckardt Score following POEM with 4 cm myotomy vs 8 cm myotomy

    At 1, 6 and 12 months, patient reported outcome of achalasia symptoms will be assessed. The Eckardt Score is a validated research tool for achalasia symptoms. Scores range from 0-12. A higher score indicates worse symptoms. We will compare Eckardt Score pre-POEM and post-PEM at various time points.

    2 years

Secondary Outcomes (3)

  • Compare procedure complications after 4 cm myotomy with POEM compared to 8 cm myotomy with POEM

    1 year

  • Compare procedural time and intra-procedural findings between 4 cm myotomy with POEM compared to 8 cm myotomy with POEM

    1 year

  • Compare post-POEM gastro-esophageal reflux between 4 cm myotomy and 8 cm myotomy using GERDQ assessment.
