Abstract
BackgroundThis study aimed to develop a simultaneously swallowing provocation test for dysphagia patients undergoing fiberoptic endoscopic evaluation of swallowing (FEES), as well as to evaluate its efficacy.MethodsIn this test, 0·4 and 2·0 mL volumes of water were dripped into the pharynx under endoscopic examination of swallowing, and determine the latency time (LT) of the swallowing reflex elicited by water. The subjects were 51 bed-bound patients with dysphagia and could be divided into two groups as 35 tube feeding and 16 oral intake subjects. Among the tube feeding subjects, 20 patients who started dysphagia rehabilitation were followed-up to 3 months.ResultsThe mean LT was 7·43 ± 7·19 seconds with 0·4 mL of test water and 5·05 ± 5·59 sec with 2·0 mL. When 0·4 mL water was dripped, LT was significantly longer in tube feeding (10·49 ± 7·97 seconds) than oral intake subgroup (5·72 ± 5·16 seconds) (p < 0·05). After the dietary intervention according to the result of FEES, 5 patients were improved in eating, and 15 patients were unchanged or even got worse among 3-months follow-up investigation. LT with 0.4 ml of test water of the Improved group was 3·16 ± 2·69 seconds and that of unchanged/worsened group was 22·6 ± 17·5 seconds, resulting in the significant difference (p < 0·05).ConclusionsThe results of this study suggest that our endoscopic swallowing test as swallowing provocation test with FEES is a useful examination for dysphagia rehabilitation.
Highlights
This study aimed to develop a simultaneously swallowing provocation test for dysphagia patients undergoing fiberoptic endoscopic evaluation of swallowing (FEES), as well as to evaluate its efficacy
This study has advantage to detect silent aspiration especially for unawakened person. Because this Simple Swallowing Provocation Test (SSPT) developed for the predicting of pneumonia risk due to saliva aspiration at night, it is unclear whether it can use for the predicting for the possibility of oral feeding
Some fibroptic endoscopy has a catheter sheath which can use for water injection, we have developed an altered swallowing function test accompany with FEES based on the SSPT and evaluated its usefulness in clinical settings
Summary
This study aimed to develop a simultaneously swallowing provocation test for dysphagia patients undergoing fiberoptic endoscopic evaluation of swallowing (FEES), as well as to evaluate its efficacy. There are various well-known effective methods of prophylaxis for malnutrition or aspiration pneumonia in dysphagia patients, such as rehabilitation of oropharyngeal function [4], texture-modified diet [5], posture correction, and eating instruction [6], which are performed based on the diagnosis of dysphagia [7,8]. This study has advantage to detect silent aspiration especially for unawakened person. Because this SSPT developed for the predicting of pneumonia risk due to saliva aspiration at night, it is unclear whether it can use for the predicting for the possibility of oral feeding
