What it is?

Fiberoptic Endoscopic Evaluation of Swallowing (FEES) is a procedure where a flexible endoscope is inserted through the nose and into the throat to visualize the structures during swallowing. The evaluation can determine airway protection and swallowing peristalsis with real food and drink.

How long will the FEES study take?

The endoscopy is generally in place for approximately 10-15 minutes depending
on the complexity of the case. However, there is no time limit as each patient’s
needs vary.

What are the benefits?

    There are many benefits. Here are just a few:

  • No Radiation Exposure
  • No scheduling coordination with radiology departments
  • Cost effective
  • Performed at bedside
  • No waiting to be cleared from isolation precautions
  • Real-time visual feedback
  • Use of regular food/liquid
    without Barium
  • No transportation concerns
  • Immediate and timely conclusions
  • Examination at bedside
  • Allow to swallow spontaneously
  • Reduce pulmonary complications
  • Option for frequent retesting to document progress or decline in function
  • Conduct therapeutic interventions without a time limit
  • Functional, real-life situation (poor positioning, fatigue, rate of intake, and method of feeding)

Is FEES safe?

Yes, it’s very safe. There is a 1% chance of developing a nose bleed, and less than 1% chance of experiencing a vasovagal response or laryngospasm during the evaluation.
