What this trial studies

This study investigates whether applying negative pressure suction in the hypopharynx can reduce aspiration during swallowing in patients with oropharyngeal dysphagia. It focuses on individuals who have severe swallowing difficulties and are dependent on gastrostomy feeding tubes due to the risk of aspiration. The study will utilize Video Fluoroscopic Swallowing Exam (VFSE) to assess the effectiveness of this intervention. By examining the swallowing process, the researchers aim to determine if this method can improve safety and reduce the risk of pneumonia associated with aspiration.

Who should consider this trial

Good fit: Ideal candidates are patients with videofluoroscopic evidence of aspiration and who are dependent on gastrostomy tubes.

Not a fit: Patients with complete PES stricture or those unable to follow commands may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve the safety and quality of life for patients with severe swallowing difficulties.

How similar studies have performed: While this approach is novel, similar studies have shown promise in improving swallowing safety in dysphagia patients.
