Abstract:
We evaluated videofluorographic recordings of the pharynx (VF) in patients suffering from aspiration pneumonia. The patients consisted of 55 men and 6 women who consulted the ENT Department at Kumamoto University Hospital between May 1994 and February 2002. Surgery for an upper alimentary tract malignancy (16 patients) was the most frequent background feature. The number of patients with cerebrovasucular disease and neuronal/neuromuscular diseases were 11 and 12, respectively. VF enabled the misswallowing of barium into the trachea to be visualized in 38 patients. Of these 38 patients, 20 exhibited misswallowing during or after the pharyngeal stage of swallowing. Among the 23 patients in whom misswallowing was not detected, 13 had upper alimentary tract diseases. The VF findings suggested the presence of gastroesophageal clearance after swallowing. Gastro-esophageal regurgitation may be a significant factor, in addition to the silent aspiration of oral and pharyngeal secretions during the night as a trigger of recurrent aspiration pneumonia.
Insights
Videofluorography (VF) identified swallowing difficulties in aspiration pneumonia patients. Gastro-esophageal regurgitation, alongside silent aspiration, may trigger recurrent pneumonia.
Area of Science:
- Otolaryngology
- Gastroenterology
- Pulmonology
Background:
- Aspiration pneumonia is a serious condition often linked to swallowing dysfunction.
- Identifying the precise causes of aspiration is crucial for effective management.
Purpose of the Study:
- To evaluate the utility of videofluorography (VF) in diagnosing swallowing abnormalities in patients with aspiration pneumonia.
- To explore potential contributing factors to recurrent aspiration pneumonia.
Main Methods:
- Videofluorographic recordings of the pharynx were analyzed in 61 patients diagnosed with aspiration pneumonia.
- Patient histories, including underlying conditions such as malignancy, cerebrovascular disease, and neuromuscular disorders, were reviewed.
Main Results:
- VF identified misswallowing into the trachea in 38 out of 61 patients.
- Misswallowing occurred during or after the pharyngeal stage in 20 patients.
- Gastroesophageal clearance was suggested by VF findings, implicating gastro-esophageal regurgitation as a potential factor.
Conclusions:
- Videofluorography is effective in visualizing swallowing impairments associated with aspiration pneumonia.
- Gastro-esophageal regurgitation, in conjunction with silent aspiration of secretions, may be significant triggers for recurrent aspiration pneumonia.
