Surgical management of achalasia

Achalasia is a chronic esophageal motility disorder comprised of ineffective esophageal peristalsis and incomplete relaxation of the lower esophageal sphincter. This disease had historically been managed through medical means as well as endoscopic dilations. However, surgical interventions are now considered standard of care, including minimally invasive Heller myotomy, which was popularized in 1990s, followed by per oral endoscopic myotomy in the 2010s. Both surgical approaches provide acceptable resolution of dysphagia symptoms. Classification of the achalasia as well as other patient-level factors may drive the clinical decision-making between the two approaches, as well as surgical training and surgeon preference.
