Achalasia is an uncommon disorder that results from the degeneration of ganglion cells of the myenteric plexus in the lower esophageal wall. Peroral endoscopic myotomy (POEM) is a minimally invasive procedure capable of overcoming limitations of achalasia treatments. This study aimed to: 1) identify the prevalence of reflux esophagitis and asymptomatic GERD in patients who underwent POEM, and 2) evaluate patient and intraprocedural variables associated with post-POEM GERD.
