Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults 18–75 with a new diagnosis of primary achalasia confirmed by high-resolution manometry and no prior definitive therapy.

Probably not a fit

Patients with previous esophageal surgeries, secondary/pseudoachalasia, or contraindications to anesthesia may not benefit.

What this trial studies

Adults with newly diagnosed primary achalasia are randomized to receive either peroral endoscopic myotomy (POEM) or laparoscopic Heller myotomy with Dor fundoplication. The study compares symptom relief and outcomes related to esophageal function, reflux, and safety over follow-up. Procedures aim to reduce the obstruction at the esophagogastric junction, but POEM may have a higher risk of reflux while Heller with Dor includes a built-in anti-reflux component. The trial builds on previous evidence suggesting similar short- to medium-term success, while addressing durability and reflux in broader clinical settings.

Why it matters

Potential benefit: If successful, the trial could clarify which procedure offers better symptom relief with acceptable reflux risk for achalasia patients.

How similar studies have gone: Earlier randomized studies showed POEM and Heller with Dor have similar short- to medium-term success, but reflux risk differs between approaches.

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Age 18 to 75 years.
* New diagnosis of primary achalasia confirmed by high-resolution manometry according to the Chicago Classification version 4.0 (elevated median integrated relaxation pressure with 100% failed peristalsis), of any subtype (I, II or III).
* Eckardt symptom score of 4 or more at baseline.
* Upper endoscopy excluding mechanical obstruction, malignancy and pseudoachalasia.
* Treatment-naive with respect to definitive therapy (no prior Heller myotomy, prior POEM or prior pneumatic dilation). Prior botulinum-toxin injection is permitted if administered at least 6 months before enrollment.
* Fit for general anesthesia (American Society of Anesthesiologists physical status I to III).
* Able to provide written informed consent and to comply with the follow-up schedule.

Exclusion Criteria:

* Prior esophageal or gastric surgery, prior myotomy (surgical or endoscopic), or prior pneumatic dilation.
* Secondary (pseudo-) achalasia, suspected or confirmed esophagogastric malignancy, or eosinophilic esophagitis.
* Sigmoid or end-stage megaesophagus (tortuous, dilated greater than 7 cm) considered unsuitable for myotomy.
* Severe esophageal varices, significant coagulopathy, or therapy with anticoagulants that cannot be safely interrupted.
* Significant cardiopulmonary disease precluding general anesthesia or capnoperitoneum / capnomediastinum.
* Pregnancy or breastfeeding.
* Body mass index below 18.5 kg/m2 with severe malnutrition requiring prior nutritional optimization (may be re-screened after optimization).
* Inability to provide informed consent or anticipated non-compliance with follow-up.
