Esophageal motility disorder
- Diffuse esophageal spasm (DES) – Dysphagia to solids and liquids characterized by difficulty swallowing several seconds after initiating a swallow. Dysphagia is often associated with retrosternal chest pain, heartburn, and regurgitation of food.
- Nutcracker esophagus – Strong esophageal contractions associated with odynophagia or chest pain. Less commonly associated with regurgitation.
- Achalasia – Loss of ganglion cells in the LES, leading to hypertrophy of the LES and dilation of the proximal esophagus. Characterized by dysphagia, regurgitation, and chest pain. Esophagoscopy may show a corkscrew esophagus.
