Dysphagia: Validation of a new nonradiological method for the prediction of ineffective swallowing.

摘要

Ineffective pharyngeal swallowing can now be predicted in an objective, automated and nonradiological way that could eliminate the need for fluoroscopy, the tool standardly used to evaluate swallowing. To make this possible, Taher Omari and colleagues have combined high-resolution solid-state manometry with intraluminal impedance. "In the past, we have used these two measurement modalities separately-manometry to measure the strength (pressure) of the swallow and impedance to measure bolus flow," explains Omari. "By combining the two modalities, we have developed a simple to perform diagnostic test with high sensitivity and specificity for swallowing dysfunction."
