Feasibility of a Water-soluble Contrast Application Into Dysphagia Evaluation
An observational study of Dysphagia and Swallowing Disorder, run by Ulsan University Hospital at 1 site in South Korea.
Trial summary
In traditional video-fluoroscopic-swallowing study, a lipid-soluble contrast (barium sulfate) has been used more than 30 years. However, it can cause chemical pneumonitis and subsequently impair reliability of video-fluoroscopic-swallowing study if aspirated. Read more about this study

About this study
In traditional video-fluoroscopic-swallowing study, a lipid-soluble contrast (barium sulfate) has been used more than 30 years. However, it can cause chemical pneumonitis and subsequently impair reliability of video-fluoroscopic-swallowing study if aspirated. The authors reviewed the safety and usefulness of an water soluble agent-based swallowing test.
Read the detailed description
Parallel-group, case-controlled trial was conducted from September 2015 to November 2017. All the patients who referred for video-fluoroscopic-swallowing study were screened.
Based on the pre-emptive evaluation, high-risky patients were allocated to iohexol (Omnipaque)-used video-fluoroscopic-swallowing study and others were allocated to barium sulfate-used video-fluoroscopic-swallowing study.
Statistical Package for the Social Sciences 24 was used to perform statistical analysis for the data. Quantitative data were presented as mean ± standard errors.

Questions about this trial
What is this clinical trial studying?
An observational study of Dysphagia and Swallowing Disorder, run by Ulsan University Hospital at 1 site in South Korea.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 27 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Laryngeal protection (time frame: within 1 hour after video-fluoroscopic-swallowing study). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03598491, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Sep 2019; AzTrials last refreshed its copy on 7 Nov 2026.
