Modified barium swallow: clinical and radiographic correlation and relation to feeding recommendations.

Clinical and videofluoroscopic evaluation of swallowing were correlated to determine their agreement and relationship to feeding recommendations. We reviewed a total of 148 patients with swallowing difficulties, of which 93 (45 women, 48 men; mean age 62 years) were evaluated by both clinical and radiographic examinations. A variety of materials were used for clinical bedside evaluation of oral and pharyngeal function. Radiographic examination was done with variable viscosity materials and videotape recording of the oral cavity and pharynx. The severity of oral and pharyngeal abnormalities was graded and findings of the examinations were compared. The combined results of both evaluations generated an index of swallowing difficulty which was correlated to the type of diet used if oral feeding was recommended or to a nonoral route of nutrition. In the assessment of oral and pharyngeal dysfunction, clinical evaluation and radiographic examination correlated closely in 94% of patients; however, the status of pharyngeal function was not determined in 61 (66%) of the 93 patients by clinical examination alone. The combined swallowing index was calculated in 89 patients and its severity correlated significantly with the type of feeding recommended; 64 patients were placed on one of three types of diets and 25 had enteral feedings. In conclusion, combined clinical and radiographic examinations correlated well, but clinical evaluation alone was limited by failure to evaluate the pharynx in many patients. The swallowing severity correlated well with final feeding recommendations.

Videofluoroscopic evaluation of patients with Guillain-Barré syndrome.

We reviewed 14 patients with clinically confirmed Guillain-Barré syndrome for swallowing dysfunction. All had swallowing dysfunction varying from mild to severe. Six patients (43%) had equivalent impairment during oral and pharyngeal phases. Seven patients (50%) had more severe functional abnormalities during the pharyngeal phase than during the oral phase. One patient (7%) had moderate disorder during the oral phase and mild disorder during the pharyngeal phase. Thirty-six percent of the patients had moderate-to-severe dysfunction during the oral phase, and 71% had moderate-to-severe dysfunction during the pharyngeal phase. In 5 patients who had multiple sequential examinations, moderate or severe swallowing disorders improved to mild-to-moderate disorders within 4-8 weeks after the onset of the symptoms. Residual swallowing disorders may be seen in those who had severe swallowing dysfunction during the later phases of their disease. Further investigations are needed to determine if swallowing abnormalities persist after complete recovery from Guillain-Barré syndrome.

Clinical and videofluoroscopic evaluation of swallowing disorders.

Swallowing and feeding problems are common, particularly in elderly persons, and will be an increasing cause of disability as the geriatric population expands. Consequently, the need for clinical and radiologic examinations of patients who have swallowing problems will likely become commonplace. In this review, we define the problem confronting these patients, discuss the clinical and videofluoroscopic procedures used to examine patients with swallowing difficulty, and integrate the results of these examinations and their impact on feeding recommendations.
