Outcome after treatment of achalasia is usually assessed by the Eckardt score (ES). The timed barium esophagogram (TBE) is used to objectively assess esophageal clearance after treatment. High-resolution manometry with impedancemetry (HRiM) provides information on esophageal clearance of liquids in addition to motility parameters. The aim of this study was to compare esophageal clearance determined by HRiM and TBE in patients with achalasia treated by POEM.
The patients included are all patients treated by POEM at Bordeaux University Hospital between October 2020 and September 2024.
Primary POEM failure, lost to follow-up, absence of completion of the ES, TBE or HRiM pre or post poem at 3 months.
