Clinical trial Recruiting at 9 sites Phase 3 Interventional Ages 18 and up

Shorter POEM vs longer POEM for achalasia and EGJOO

Official title: PREcision MEDicine In Achalasia - A Multicenter Randomized Non-Inferiority Clinical Trial of Short Tailored POEM vs. Standard POEM for Non-Spastic Achalasia and A Multicenter Prospective Cohort Study of Long Tailored POEM for Spastic Esophageal Motility Disorders

Run by Northwestern University · NCT07293650 · Data updated 2026-11-12

A 3-phase randomized trial tests whether a shorter 4 cm POEM works as well as the standard 9 cm POEM for easing swallowing difficulties in adults with type I/II achalasia or EGJ outflow obstruction.

Is this trial a fit for you?

Likely a good fit

Adults (18+) with type I or II achalasia or cEGJOO and Eckardt score greater than 3.

Probably not a fit

Patients who do not respond to the shorter myotomy or who have conditions outside the eligible criteria may not benefit.

What this trial studies

This randomized, controlled trial compares two Per-Oral Endoscopic Myotomy approaches for treating achalasia types I/II and EGJOO. Participants undergo either a standard 9 cm myotomy or a tailored 4 cm myotomy and are followed with symptom questionnaires over two years. The study aims to see if the shorter cut provides similar symptom relief with potentially fewer side effects, such as reflux or myotomy-related complications. Enrollment targets 370 patients across multiple sites, with data collection from medical records and patient surveys. The trial is conducted with oversight from Northwestern University and NIDDK, involving Mayo Clinic Arizona, UC San Diego, and University of Colorado Denver.

Why it matters

Potential benefit: If successful, patients may experience similar symptom relief with a shorter myotomy and potentially fewer reflux and other complications.

How similar studies have gone: Previous data suggest POEM is effective, but this study examines whether a shorter myotomy can match efficacy with fewer adverse effects—this is a novel comparison in this context.
