Abstract.

The radiologic characteristics of pharyngo-esophageal (PE) dysfunction in Parkinson's disease (PD) are not well established, partly because most previous studies have examined only small numbers of patients. We administered a dynamic videofluoroscopic swallowing function study to 71 patients with idiopathic PD. Using the Hoehn and Yahr disease severity scale, patients were subdivided into those with mild/moderate disease, subgroup I (n = 38), and advanced PD disease, subgroup II (n = 33). From pharyngeal ingestion to gastric emptying, bolus transport was normal in only 2 patients. The most common abnormalities occurring during pharyngeal ingestion included impaired motility, vallecular and pyriform sinus stasis, supraglottic and glottic aspiration, and deficient epiglottic positioning and range of motion. Esophageal abnormalities were multiple but most commonly included delayed transport, stasis, bolus redirection, and tertiary contractions. Typical aberrations of lower esophageal sphincter (LES) function included an open or delayed opening of the LES and gastro-esophageal reflux. A pathogenesis linking PE with the pathology of PD is proposed.

Key words: Pharyngoesophageal dysfunction — Parkinson's disease — Radiologic evaluation — Gastro-esophageal reflux — Deglutition — Deglutition disorders.
