Objective:To investigate the application value of fiberoptic endoscopic evaluation of swallowing (FEES) in patients with dysphagia after stroke.Methods:A total of 200 patients with dysphagia who received treatment in Wenzhou Hospital of Traditional Chinese Medicine from January 2019 to December 2020 were included in this study. All patients underwent videofluoroscopic swallowing study (VFFS) and FEES. Examination results and the incidence of adverse reactions were compared between VFFS and FEES.Results:VFFS results revealed that oral food residue occurred in 122 patients, food leakage in 168 patients, food aspiration in 170 patients, epiglottis valley residue in 179 patients, pyriform sinus residue in 184 patients, cricopharyngeus muscle dysfunction in 61 patients, and abnormal esophageal peristalsis in 58 patients. FEES results revealed that food leakage occurred in 173 patients, food penetration in 151 patients, food aspiration in 180 patients, food retention in 166 patients, and vocal neoplasm in 21 patients. The incidence of adverse reactions generated in FEES was lower than that in VFFS (5.5% vs. 12.0%, χ2 = 5.29, P < 0.05). Conclusion:FEES has high sensitivity and safety in the detection of dysphagia after stroke, and it has important guiding significance for the treatment of dysphagia.
