An appraisal of current dysphagia diagnosis and treatment strategies

Dysphagia is a common, serious health problem with a wide variety of etiologies and manifestations. This review gives a general overview of diagnostic and therapeutic options for oropharyngeal as well as esophageal swallowing disorders respecting the considerable progress made over recent years. Diagnosis can be challenging and requires expertise in interpretation of symptoms and patient history. Endoscopy, barium radiography and manometry are still the diagnostic mainstays. Classification of esophageal motor-disorders has been revolutionized with the introduction of high-resolution esophageal pressure topography and a new standardized classification algorithm. Automated integrated impedance manometry is a promising upcoming tool for objective evaluation of oropharyngeal dysphagia, in non-obstructive esophageal dysphagia and prediction of post fundoplication dysphagia risk. Impedance planimetry provides new diagnostic information on esophageal and LES-distensibility and allows controlled therapeutic dilatation without the need for radiation. Peroral endoscopic myotomy is a promising therapeutic approach for achalasia and spastic motility disorders.
