Achalasia is a rare neurodegenerative motility disorder of the esophagus with an annual incidence and prevalence of approximately 1.6 cases per 100,000 and 10 cases per 100,000 individuals, respectively [122]. Recent data with the use of high‐resolution manometry (HRM) suggests that the prevalence may be higher, as HRM has a greater diagnostic yield and may lead to an earlier diagnosis compared to conventional manometry [123]. Achalasia affects males and females equally without racial predilection. It can occur at any age, albeit rare in childhood, with a peak incidence between the ages of 25 to 60 years old. Expanded focused discussion on achalasia can be found in Chapter 13.
