Résumé : Diagnostic criteria for esophageal motor disorders have recently been updated with the advent of high-resolution manometry that gives a precise mapping of peristaltic abnormalities and an indirect view of bolus transit problems. Achalasia, the best-defined motor disorder, is now divided in subsets of manometric phenotypes that predict outcome of treatment and guide our therapeutic approach. Pharmacological therapy using smooth muscle relaxants for spastic esophageal disorders remains poorly effective and used only as a bridge to more effective therapies : endoscopic balloon dilation and surgical myotomy are both effective therapies in achalasia, myotomy being considered as the preferred approach in children because it is aimed to be definitive, while dilations usually have to be repeated. Recently, peroral endoscopic myotomy was introduced as an alternative to surgical myotomy for achalasia, and was rapidly adopted in tertiary referral centers. Showing excellent short-term results, this technique might be also proposed for other esophageal spastic disorders. Gastroesophageal reflux disease and eosinophilic esophagitis, two prevalent diseases in children that may be associated with hypotensive and hypertensive peristaltic abnormalities, have to be searched because specific effective therapies exist for these diseases that may cure the motility disorders.
