Esophageal motility disorders, excluding achalasia, lack population-based studies. The 2 best-characterized motility disorders, achalasia and DES, represent only a small percentage of diagnosed motility disorders. The incidence of achalasia is 1-3 case per 100,000 population per year. [1] As with any other chronic illness, prevalence exceeds incidence significantly. Familial clustering is observed, but a genetic relationship is not established. Nutcracker esophagus is the most common motility disorder (>40% of all motility disorders diagnosed), but it is the most controversial in significance.
