The efficacy of peroral endoscopic myotomy vs. pneumatic dilation as treatment for patients with achalasia suffering from persistent or recurrent symptoms after laparoscopic Heller myotomy. A RANDOMIZED CLINICAL TRIAL

For achalasia patients with persistent or recurrent symptoms after laparoscopic Heller myotomy (LHM), pneumatic dilation (PD) is the most frequently used treatment. Per-oral endoscopic myotomy (POEM) is increasingly being investigated as rescue therapy. This study aimed to determine the efficacy of POEM versus PD for patients with persistent or recurrent symptoms after LHM.
