Abstract
Texture modification in the form of gels or jellies is used for patients with dysphagia. For over 20 years, our group has been using gelatin jellies, a type of gel, as a starting diet for patients with dysphagia. Gelatin jellies are served in a small-sliced form and swallowed whole. In sliced jelly whole swallowing (SJWS), sliced gelatin jelly (SGJ) passes through the pharynx in one lump without collapsing. This study aimed to examine the usefulness of SJWS. We analyzed the images of videofluoroscopic swallowing studies performed using the normalized residue ratio scale (NRRSv: vallecula, NRRSp: pyriform sinus), the penetration–aspiration scale (PAS), and pharyngeal transit time (PTT) in 50 patients with dysphagia and compared the results in a prospective study. SJWS had significantly less residue in both NRRSv and NRRSp than in moderately thickened liquid swallowing. No significant differences in PAS scores were found between SGJ and moderately thickened liquid. Additionally, no significant differences in PTT scores were noted between the two. This study demonstrated the usefulness of SJWS in improving swallowing safety in patients with dysphagia. Further studies are needed to evaluate the reproducibility of the test, the comparison of SGJ with other thickened liquids, and the safety of SJWS for different diseases.
