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>Methods.</i> Clinical data of achalasia of cardia (AC) patients who underwent POEM in our center during January 2014 to January 2015 was collected (34 cases).
