Diagnosing esophageal strictures

Diagnosis of esophageal stricture will begin with a medical history and physical exam. Tests may include: 

  • Fiberoptic endoscopic evaluation of swallowing (FEES): An endoscope (a thin, lighted tube with a camera attached to it) is passed through your mouth and esophagus. Your physician can look at pictures of your digestive tract and take a biopsy (tissue sample) for examination under a microscope.
  • Esophagram/barium swallow: Special X-rays are taken of your esophagus after you drink barium, a contrast material that coats your esophagus and shows up well on X-rays. 
  • CT scan: A computed tomography (CT) scan combines X-ray and computer technology to produce detailed cross-sectional images of your esophagus.
