title: Esophageal motor disorders.
abstract: Motor dysfunction is responsible for symptomatic illnesses both in the proximal skeletal muscle region and in the distal smooth muscle esophagus. Practical methods for diagnosing and treating oropharyngeal dysphagia continue to reach consensus. Achalasia, the most significant of the distal motor disorders, is of investigative interest because of the expanded armamentarium of treatment options. Minimally invasive surgical methods have taken an important foothold as a primary treatment of this disorder. Appreciation is growing for sensory dysfunction that accompanies distal motor disorders. Such dysfunction may help explain the observed discrepancies between symptoms and measurable motility abnormality.
