Objectives:The aim of the present study is two folds, (1) to investigate the materials of contrast
media and foods used in the videofluoroscopic swallowing study(VFSS), (2) to
investigate the differences between the VFSS results of liquid and solid foods as the test
foods.
Methods: Literature search and data interpretation were performed according to a systematic
method: (i) problem specification, (ii) a plan for the literature search, (iii) literature search
and retrieval, and (iv) data interpretation. The problem was specified as follows: Which test
materials were used for VFSS? Two data bases were searched using specified indexing terms.
The contrast media and foods used by VFSS were extracted from the selected publications.
And, we made a careful comparative review of the VFSS results that the patients swallowed the
liquid and solid foods.
Results: The literature search yielded 561 titles and abstracts. In 34 publications of 561, contrast
media such as Iodine were used except for barium sulfate. Solid foods as a test food were
used in 105 publications. Finally, 14 publications of 105 described separately the VFSS results
of liquid and solid foods about the aspiration were selected. Aspiration often occurred by
swallowing liquids, but few solid foods. On the other hand, the residue rate of the solid foods
at the pharynx was higher than that of liquids.
Conclusion: The occurrence of the aspiration and penetration was various depending on the
kinds of foods. Therefore, we should select the test foods used by VFSS according to the individual
patient’s symptoms.
