We, therefore, designed this propensity score (PS) case-control study with the aim of evaluating how POEM compares to the long-standing laparoscopic Heller myotomy + Dor fundoplication (LHD) and verifying if it may really replace the latter as the first-line treatment for achalasia.
Types I and II achalasia respond well to POEM, LHM, and PD, while most studies have shown that type III achalasia responds better to POEM than to LHM and PD.
<i>Background.</i> Here we aimed to evaluate and compare the efficacy and safety between partial full-thickness myotomy and circular muscle myotomy during POEM procedure in achalasia patients.
