title: Technetium tin colloid test detecting symptomless dysphagia and ACE inhibitor prevented occurrence of aspiration pneumonia.
abstract: Symptomless dysphagia and swallowing disorders play a very important role in the pathogenesis of aspiration pneumonia. A videofluoroscopic examination and a simple two-step swallowing provocation test (STS-SPT) could be useful for detection of swallowing disorders in elderly patients with stroke, however, there is no report on such a test for detection of symptomless dysphagia. We administered 1 ml Technetium Tin Colloid (99mTC) to the patient during sleep via a nasal catheter placed in the mouth. At 09:00 h the next day, symptomless dysphagia was checked for by imaging. Improvement of the symptomless dysphagia was observed, and thus we could prevent the occurrence of aspiration pneumonia. The 99mTC test was particularly useful in detecting symptomless dysphagia in elderly patients with stroke.
