To study the application value of flexible endoscopic examination of swallowing(FEES) for the aspiration screening, the diagnosis of dysphagia and evaluation of the therapeutic effectin acute stroke patients with dysphagia.

Three hundred and seventy-three patients with acute stroke who hospitalized from October 2015 to January 2020 in Dalian Municipal Central Hospital Affiliated of Dalian Medical University and underwent FEES for analyzing the characteristic performance were enrolled, and 11 cases of them were examined by video fluoroscopic swallowing study (VFSS). The results of the reliability of diagnosis dysphagia of the two methods were compared. The results of FEES for assessing the recovery effect after treatment were evaluated.

In 373 patients, the FEES revealed 268 cases(71.85%) of aspiration (99 cases) were recessive aspiration, which was better than that in water swallow test (50.94%, 190/373). Patients with potential cricopharyngeus achalasia got the same results through both of VFSS and FEES. FEES could provide more positive indicators and guide clinical rehabilitation treatment and objective assessment of rehabilitation effectiveness.

Acute stroke patients with dysphagia have characteristic laryngeal performance. FEES is simple to operate and has high application value.
