Evaluating esophageal clearance in achalasia using advanced imaging techniques

Official title: Contribution of High-resolution Manometry With Impedancemetry for the Evaluation of Esophageal Clearance in Achalasia

Run by University Hospital, Bordeaux · NCT06230536 · Data updated 2026-11-12

This study is testing if a new way to measure how well the esophagus clears food can replace an older method that uses radiation for patients with achalasia who have had a specific surgery.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients treated with POEM for achalasia at Bordeaux University Hospital between October 2020 and September 2024.

Probably not a fit

Patients who experience primary POEM failure or are lost to follow-up will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to compare the effectiveness of high-resolution manometry with impedancemetry (HRiM) and timed barium esophagogram (TBE) in assessing esophageal clearance in patients with achalasia who have undergone peroral endoscopic myotomy (POEM). Patients will be evaluated before and after treatment using the Eckardt score, TBE, and HRiM to determine the prognostic value of these assessments on long-term symptoms. The study seeks to establish whether HRiM can replace TBE, which involves radiation exposure, in routine evaluations of esophageal clearance.

Why it matters

Potential benefit: If successful, this study could lead to improved assessment methods for esophageal clearance in achalasia, enhancing patient outcomes and reducing radiation exposure.

How similar studies have gone: While the use of HRiM is gaining traction, this specific comparison with TBE in the context of achalasia treatment is relatively novel and has not been extensively tested.
