Endoscopic Swallowing Evaluation

An endoscopic swallowing evaluation known as fiberoptic endoscopic evaluation of swallowing (FEES) is used to assess the following symptoms and conditions:

  • Trouble swallowing liquid, food or medications
  • Feeling a lump-like sensation in your throat
  • Having a history of reflux
  • Having a history of swallowing difficulties due to stroke, Parkinson's disease or other neurological disorder

Unlike a barium swallow, a FEES test does not involve the use of X-rays.

What Does a Fiberoptic Endoscopic Evaluation of Swallowing Test Involve?

Otolaryngologists of the Jefferson Voice and Swallowing Center along with speech-language pathologists of the Department of Rehabilitation Medicine will perform this procedure to record images of your throat and voice box and see how well you are able to swallow liquids or foods.
