Outcomes of Short-length vs Standard-length Myotomy Using Per-Oral Endoscopic Myotomy (POEM) for Achalasia: A Randomized Controlled Pilot Study
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.
• All patients aged 18+ diagnosed with Type I or Type II achalasia, and patients with EGJ Outflow Obstruction with features of achalasia based on HRM or Endoscopic Functional Lumen Imaging Probe (EndoFLIP)
• All subjects must have given signed, informed consent prior to registration in the study
